Windows XP Professional x64 Edition


1. Introduction


After a few unplanned delays, Microsoft has finally released its Windows XP Professional x64 Edition. The first step into the 64-bit world was made by AMD. AMD has been waiting 3 years for this release while users who have AMD's x86-64 platform were only able up till now to take advantage of the full capabilities with the freeware Linux operating system.

For a long time, Intel had ignored the 64-Bit architecture. It is quite interesting that, a few weeks after the release of Intel's CPU with x86-64 architecture, the Windows XP 64-Bit edition has also been released. It appears as if Microsoft was holding back on its release until the new CPU was ready.

So while the x86-64 bit architecture is gaining momentum becoming more and more popular for its features and with newer CPUs like the Celeron D processors expected in the near future, it is time then to take a deep look into the new operating system from Microsoft which has promised.so much.


2. System Specifications

What is this version? Does my machine support it?

This Windows release is the 64-bit version of the Windows XP 32-bit operation system. The interface is similar to Windows XP but there are a lot of changes. Microsoft has also updated the Windows XP kernel which is also partly based on Windows 2003. Windows x64 will run on the AMD Athlon 64 and AMD Opteron with AMD64, and the Intel Xeon and Intel Pentium 4 with EM64T. Windows XP Professional 64-Bit Edition and Windows XP Professional 32-bit differ in performance and capacity. As a result, the setup, disk space and device driver requirements also differ. You can't install this version on a computer that has an x86 (32 bit) architecture. Don't confuse Windows XP Professional x64 Edition with Windows XP Professional 64-bit Edition. Windows XP x64 is for x64 systems and Windows XP 64-bit is for Intel Itanium-based microprocessors.

Windows XP Professional x64 Edition only comes in professional version. (From now on when we refer to Windows XP Professional we mean the 32-Bit version and when we refer to Windows XP Professional x64 Edition we mean the 64-Bit version).

Below is a comparison table listing the setup requirements for both Windows XP Professional and Windows XP Professional 64-Bit Edition.

As we can see, Windows x64 can support a lot more memory than Windows XP 32-bit Edition. Desktop users may not see big differences, as few users need more than 4GB of virtual memory. A big advantage we can see is with the memory subsystem, for example with the Non-paged pool. This pool is used by the operating system for virtual addresses, which remain in memory and are not paged out to the hard disk. The bigger the pool, the faster the operating system operates.

Except that, the additional (and wider) general-purpose registers of the x64 architecture allow for significant gains in compiler efficiency and overall application speed. With more registers, there is less need to write out persistent data to memory, only to have to read it back a few instructions later. Another gain with the additional, wider registers is faster function calls. Up to four arguments can be passed in registers to a function which is a big improvement over the x86 approach of pushing and popping arguments off and onto the stack for every floating-point operation.

Notice: The current x64 Editions of Windows actually only use 40 bits for addressing memory, yielding an address space of 240 or 16 TB. The theoretical maximum of a full 64-Bits of address space is 264 or 16 exabytes (1.6x1019).

However, a 64-Bit system needs more memory in order to function properly. As we can see from the table below, Windows x64 kernel takes 60% more memory than Windows XP 32-Bit Edition. As a result, in order to gain the same performance level with the 32-Bit, users must upgrade their system memory.

3. Product Overview

Why upgrade to Windows x64? Do I really need this upgrade? What am I going to gain from this release?

Windows XP Professional x64 Edition Overview

According to Microsoft, Windows XP Professional x64 Edition supports the latest class of Intel Itanium processors designed for users who need to create and manipulate large amounts of complex data.

Windows XP 64-bit Edition is designed for users that require large amounts of memory and floating point performance in areas such as mechanical design and analysis, 3-D animation, video editing and composition, and scientific and high-performance computing applications.

Based on the Explicitly Parallel Instruction Set Computing (EPIC) design technology, the Intel Itanium processor can perform up to 20 operations simultaneously by using advanced compiling techniques and large processor resources. This means that the applications can preload substantial amounts of data into virtual memory to enable rapid access by the processor. This reduces the time for loading data into virtual memory and the time for seeking, reading, and writing data to storage devices and as a result, applications to run faster and more efficiently.

· Performance Benefits

With the 64-bit version, engineers can create large, more complex models in fields such as automobile or airplane design. This means that engineers can use a lot of new techniques to improve product design. Except that, 3-D animators, digital artists, and game developers, can render more complex 3-D models faster that before. According to Microsoft, in the areas of scientific and high performance computing, Windows XP Professional x64 Edition will aid in oil and gas exploration, seismic analysis, computational fluid dynamics and scientific visualization among other applications. The hardcore gamers will experience more complex textures that require biggest amount of memory with more image effects on the upcoming games for the 64-bit Windows,without having to worry about the performance.


· Increased amount of memory used

In our days, there are a lot of users that are reaching the memory limits on the 32-bit systems. Here comes the new x64 Edition to solve this problem. With Windows XP Professional x64 Edition, the memory limit has increased to 128 gigabytes (GB) of RAM and 16 terabytes of virtual memory. The amount of virtual memory is going to be increased even higher in the future, as new hardware capabilities will be available.

· Single Desktop for Technical and Business Applications

Windows XP Professional x64 Edition will provide a single desktop for technical and business applications, eliminating the need for technical workstation users to maintain a PC for business applications and a separate workstation for high-end technical applications. Most of the existing 32-bit programs will run on the Windows XP Professional x64 Edition in comparable performance to 32-bit Windows, hopefully it will be boosted.

Server Administrators will not have to worry about compatibility problems when they want to setup a server with both Windows XP Professional x64 Edition systems and 32-bit systems. Furthermore, they can manage them with the same administrative tools.


On Windows XP Professional x64 Edition, Task Manager displays the 32-bit programs that run through WOW64 emulator with an "*32" extension.

· Same programming model

Developers with 32-bit skills will be comfortable and quickly productive in the 64-bit Windows environment, finding it virtually identical to the development environment for 32-bit Windows. The Microsoft Win64 application-programming interface (API) is the same with the Microsoft Win32 API except some necessary modifications to acquire best performance on every platform.
Finally, the feature set is the same as the previous 32-bit Windows with the necessary modifications which includes: UI and programming models, networking, security, graphics, multimedia, directory service, Plug and Play, and tools features.


4. Compatibility

Am I going to have any problem with the new Windows? My old games and programs are going to work in the new release?

There are a lot of products such as cameras, game pads, TV-tuners that are not yet supported. As a result, it is recommended to make a research on the Internet to find out if the product that you want to use with the Windows x64 is supported. In the future all the companies are going to release the necessary drivers so if there is a device that you don’t care too must to use it for now you can still install Windows x64

.If you try to update your Windows from the 64-Bit version of Internet Explorer you will get an error message displaying that you have to use the 32-Bit version

Windows XP Professional x64 Edition includes IExplorer in both 32 and 64-Bit versions for compatibility reasons. For example, windows update works only with the 32-Bit version for now.

We have a list with most of the companies that have already released drivers for the Windows XP Professional x64 Edition here and a list with programs that are not supported here.

As you can see, the list of unsupported programs is quite large while the drivers list is quit short and a lot of users will be disappointed after reading them However, this is probably going to change with a service pack/ patch or a unique release for every program.

DirectX Diagnostic tool also comes in 2 versions

Last but lot least, Windows XP Professional x64 Edition does not support 16-Bit applications and DOS applications. Users that are still using 16-Bit applications will not be able to run them on the new operating system. Moreover, some 32-Bit applications use 16-bit code during installation, which means that these programs cannot be installed. Finally, all kernel mode drivers must be 64-Bit. No support is available for 32-Bit drivers and applications that depend on a 32-Bit kernel mode driver will not run, even in the WOW64 subsystem.

From now on, the most of the programs that are released on 2 versions, will let you to select the version you want to install

5. Security Issues

What about security with the new Windows? What are the differences from the previous Windows?

An important new feature in the x64 processor architecture is the Data Execution Protection (DEP) bit that controls which areas of memory can be used to execute code. While AMD and Intel have different names and slightly different implementations for this feature, the result is an enhanced layer of hardware protection against some of the most destructive worms and exploits of the past several years.

Data Execution Protection

Beginning with Windows XP Service Pack 2 (SP2) and continuing with Windows Server 2003 SP1 and Windows XP Professional x64 Edition, Windows uses DEP to prevent malicious code from being able to execute, even when a buffer overrun occurs. Even without a processor that supports DEP in hardware, Windows is able to detect code running from memory locations that it should not.

With the introduction of x64 processors, both AMD and Intel added hardware support for DEP. The processor sets the No Execute bit (for AMD processors) or the Execute Disable bit (for Intel processors) on all entries in the memory address table that are for data only and should not be executed. If code attempts to execute from within an area of memory marked as data only, Windows will raise a status access violation exception and terminate the process.

While DEP is by no means a substitute for a well-designed and implemented anti-virus and anti-malware deployment in any organization, it is an important additional layer of protection that would have prevented the spread of the MSBlaster worm had it been widely implemented at the time.

The x64 versions of Windows also support Microsoft's PatchGuard technology that prevents non-Microsoft originated programs from patching the Windows kernel. This technology, available only on Windows x64 Editions, prevents kernel mode drivers from extending or replacing kernel services including system service dispatch tables, the interrupt descriptor table (IDT), and the global descriptor table (GDT). Third-party software is also prevented from allocating kernel stacks or patching any part of the kernel.


6. Gaming Experience

What about playing games on the Windows XP Professional x64 Edition? Are my old games going to work with this release? What about the new upcoming games? Are they going to be different from the Windows XP Professional version?

On the gaming side, some users will be surprised to learn that some games may not work correctly under Windows XP Professional x64 Edition. For example, games that are using Starforce copy protection cannot be installed because the driver for the copy protection is present only as a 32-bit version.

But games that will be optimized for the Windows XP Professional x64 Edition are coming fast. The first game has already been released. It is the Shadow Ops: Red Mercury. The changes are going to be a lot because of the benefits of the 64-Bit technology that we discussed at the beginning (vast memory space and advanced multi-media processing capabilities). From AMD.com we see a press release saying that "...With the 64-Bit version of Shadow Ops: Red Mercury, gamers will notice larger and more detailed areas to explore, breakthrough artificial intelligence (AI), and never-before-seen textures that compel players to gawk in amazement". Atari.com has also released this announcement: "The 64-Bit version of the game will be included with the 32-Bit version and will allow for improved textures, better image quality, faster game performance and an enhanced gameplay experience.... Gamers who install the 64-Bit version of Shadow Ops: Red Mercury, get access to the 64-Bit only level of detail, with mind-blowing texture quality, enormous map sizes and amazingly enhanced artificial intelligence, creating an exceptional game play experience." So, you can expect differences in the quality of the textures of the ground, the gun, the shadows of the characters, more objects in the environment or more detailed, differences in lighting and shadow enhacements.We have a photo to compare the changes.


Shadow Ops: Red Mercury 32-Bit version


Shadow Ops: Red Mercury 64-Bit version

You can take a look at some more photos with the changes from the 32-Bit to 64-Bit version that we found on the game homepage here.

Comparing this game with other games like half life 2 and doom 3, we can accept that the 64-Bit version of shadow ops hasn't anything better to present in the graphics department. But don't be misled by the supposed changes from the 32-bit to the 64-bit versions. The result is still poor and not as good as on other successful 32-bit games like half life 2, far cry and doom 3.

Unfortunately, the game does not support any benchmarking tool for now and FRAPS (the program that we use to count frames per second in games that don't support benchmark options) does not work correctly on Windows XP Professional x64 Edition with the 64-Bit version of Shadow Ops. As soon as we find a way to run a benchmark test on this game, we will update this review.

Another game that is expected to release a 64-Bit patch is Far Cry. Far cry is a very popular, awesome First Person Shooter (FPS) based on a last generation 3D engine named CryEngine. Real-time editing, bump-mapping, static lights, network system, integrated physics system, shaders, shadows and a dynamic music system are just some of the state of-the-art features that CryEngine offers. According to AMD.com, "AMD64 technology enables Far Cry's next-generation engine to push the threshold of action gaming with unprecedented AI, Polybump™ mapping, advanced environmental physics, destructible terrain, dynamic lighting, motion-capture animation, and total surround sound. Far Cry's unbelievable 800-meter draw distance redefines the idea of long-range gameplay." More information can be found here.


7. Availability And Price

Are there a lot of 64-bit choices out there? Is the home user able to find 64-bit processors easily? How much more will it cost compared with an x86 processor?

AMD and Intel offer a broad range of x64 processors, and both original equipment manufacturers (OEMs) and system builders are shipping x64 systems that range from enthusiast desktops and laptop machines all the way up to 4-way multiprocessor server machines. With the release of the x64 Editions of Windows, 64-bit is ready to become the mainstream of computing.

By the end of 2005, Microsoft hopes that all new server class machines shipping will be 64-bit. And at the end of 2006, the majority of new PCs and workstations will also be 64-bit.

The current price of x86 and x64 processors is going to be essentially identical, making the choice of an x64-capable processor the clear preference. Still, the lower end consumer x86 processors and computers are significantly cheaper than x64 machines and will continue to be the main choice for most cost-conscious consumers.

After reading the answers to the questions posed, if you are satisfied with the result and with the research you may have done, you can continue to install Windows x64.


8. Windows Installation

If you are familiar with the installation of Windows XP PROFFESIONAL or HOME versions, then you will not have any problems installing this version. (You can buy Windows XP Professional x64 Edition from Microsoft.com. For those who already have an x64 computer running Windows XP Professional (32-Bit), they can exchange their 32-Bit edition of Windows XP for Windows XP Professional x64 Edition.)

· Phase 1

You have 2 options on how you are going to install XP Professional x64 Edition.
1. Install Windows x64 over an existing operating system.
As a result, you will not be able to recover your previous operating system. The previous WINDOWS folder will be deleted and you will lose all registry values. Nothing else is going to be deleted. (Although your previous programs will not be lost, there is a possibility that they will not function correctly).
2. Make a new partition or use a second Hard Disk Drive to install Windows x64.
This option is recommended. With this option you will lose only 2GB of disk space, the previous operating system will still be functional. You will have the ability to select with which operating system you want to start.

Before continuing with the installation, check the List with the devices that are supported at this time. Also, if you have a small computer system interface (SCSI) drive or a raid controller, you will need 64-Bit Drivers. Check our List will the current drivers that are available.

· Phase 2

First, Make sure that you have “Boot From CD” Function enabled in the BIOS settings.
In order to do this, press the “Delete” button (or the respective key for your BIOS setup) during the Power-On Self Test (POST). In the Boot Sequence menu select your CD/DVD-Rom device as the “First BOOT Device” (if there is an option ”Boot From CD”, enable it). Insert the Windows x64 CD-Rom and restart your computer.
After the POST test, the prompt "Press any key to boot from CD" will appear, press any key at the prompt, and the installation will begin. (If you want to install a SCSI drive or a raid controller, insert the floppy disk you have created with the 64-Bit drivers).

When the Installation menu appears, select the hard disk on which you want to install Windows x64. The installation will start after the necessary restart.

After the installation, when you logon to Windows, you should see this screen:

Click to enlarge - The first screen that you will see after the installation

The next step, is drivers installation.


9. Drivers Installation

Most probably after the OS installation, the system will not recognize some of your hardware components and in the device manager tab, you will see something like this:

Click to enlarge - The device manager after the windows installation
Device Manager Window

Don't panic. We are going to solve this problem.

Windows XP Professional x64 Edition requires the installation of 64-Bit drivers only. You cannot install 32-Bit drivers. There are some device drivers that have been modified to allow installation of 64-Bit and 32-Bit drivers from the same .inf file. This is necessary to avoid installing wrong drivers under the wrong platform.

When installing drivers for the Windows XP Professional x64 Edition, be sure that the provider says that the driver works on “Windows XP Professional x64 Edition” and not on the “Microsoft Windows XP” or “Windows XP Professional”.
Some users will probably remember a time when Windows 2000 had exactly the same problem after their initial release when the operating system didn’t recognize a whole lot of hardware. We have already mentioned our list of companies that have released drivers for their products which is also posted in our forums. Click here to see the full list.

You must install drivers in the following order, in order to install the drivers correctly and to avoid conflicts with other drivers. After any install you make, it is recommended you restart your computer.

1. Motherboard Drivers
2. Graphic Card Drivers
3. Sound Card Drivers
4. Any other device drivers

Driver Installation procedure

After the driver installation, we are ready to test our system. In the next page you will find information about the computer that we used to run all the tests on and what programs we used.


10. Test System

The system that we ran all the tests on is listed below. For each operating system, we used a separate partition with the same capacity (15GB). We decided to use an AMD processor because in contrast to Intel's Itanium, AMD's 64-bit architecture can handle 32-bit code very fast, which makes for a smooth transition to 64-bit computing.

11. Game Benchmarks - Far Cry

You are Jack Carver running your own boat charter business in beautiful Micronesia. With a past best left behind you, you'll be focusing on your present assignment: escorting an ambitious journalist named Valerie Cortez to the Island of Cabatu. It seems like a piece of cake, but you'll soon learn: paradise can be hell.

Farcry is an awesome First Person Shooter (FPS) based on a last generation 3D engine named as CryEngine. Real-time editing, bump-mapping, static lights, network system, integrated physics system, shaders, shadows and a dynamic music system are just some of the state of-the-art features that the CryEngine offers.

A great advantage and strong point of the CryEngine is its physics system which supports character inverse kinematics, vehicles, rigid bodies, liquid, rag doll, cloth and body effects. All physics seem to be very realistic and you never get bored when facing enemies, since character models have multiple animations that blend in believable ways.

With an integrated shader system and a massive terrain which maximizes the view distance to 2km, these features make Farcry a perfect action game and also a referable benchmark to speak of.

- Benchmark Settings

For this game we recorded a custom demo from the start of the Rebellion stage. We chose an indoor scene in order to avoid getting the CPU bound effect. This will result in slightly higher results since it is also less GPU intensive

The latest patch (1.3) was used for our tests which updates the game's graphics engine to use the 3.0 Shader model. This option is only supported for the 6800 series.

The resolutions we ran the demo under, are as follows: 800x600,1024x768, 1280x1024 and 1600x1200. The tests was committed with Anti Aliasing at 6x (AA) and Anisotropic Filtering at 12x (AF). All tests were taken with Jack's flashlight on, to increase the game's demands from the graphics cards and with ai_update_interval set to zero so that the results are subjective.

In this game, we notice a performance drop of around 7% with Windows XP x64 Edition while running at the resolution of 800x600. This shows that the 32-Bit emulator for the Windows XP Professional x64 Edition (WOW64) cannot reach the performance of Windows XP Professional. We were happy to see that with the other resolutions, the performance difference was less than 1%.


12. Game Benchmarks - Colin McRae 2005

For all you racing fans out there, this test is for you and will represent the Racing game category in our benchmarks.

 

From the graphics point of view the first thing you'll notice in the game is the excellent amount detail of your racing car. High resolution textures on the car and lighting make it quite impressive. All the eye candy such as the sun reflection in the virtual camera are still the same as the older CM versions but motion blur has been added when your card hits something hard which will happen most often if you're new to the racing simulation world.

To measure performance on the game we used fraps to get the average fps of the whole 8th stage of UK which is actually the only stage you get to play on the demo.

However, with Colin MCRae 2005, we clocked exacly the same frames per second at each resolution. WOW64 did a great job with this game showing that we could expect to see the same performance with some games and maybe even a little better.


13. Game Benchmarks - Half Life 2

Half life 2 is no doubt the most anticipated pc game of all times. Gamers keeping the excellence of Half Life 1 in their mind as well as the remarkable E3 demo preview, have been anxiously waiting for the much delayed release of HL2.

Regarding the storyline, the player again picks up the crowbar of research scientist Gordon Freeman, who finds himself on an alien-infested Earth being picked to the bone, its resources depleted, its populace dwindling. Freeman is thrust into the unenviable role of rescuing the world from the wrong he unleashed back at Black Mesa. And a lot of people he cares about are counting on him.

Characters - Advanced facial animation system delivers the most sophisticated in-game characters ever seen. With 40 distinct facial "muscles," human characters convey the full array of human emotion, and respond to the player with fluidity and intelligence.

Physics - From pebbles to water to 2-ton trucks respond as expected, as they obey the laws of mass, friction, gravity, and buoyancy.

Graphics - Source's shader-based renderer, like the one used at Pixar to create movies such as Toy Story® and Monster's, Inc.®, creates the most beautiful and realistic environments ever seen in a video game.

AI - Neither friends nor enemies charge blindly into the fray. They can assess threats, navigate tricky terrain, and fashion weapons from whatever is at hand.

To measure performance we used the Video Stress Test(VST) that is available in the CounterStrike:Source beta available through Steam. We set all the details to the highest level and each time changed the resolution from 800x600 up to 1600x1200.

As we can see, Windows XP Professional has a performance lead with this 32-Bit game, up to 5% at 800x600 resolution and as the resolution increases, the performance difference increases up to 9% at the 1600x120 resolution. The Windows x64 emulator, WOW64 is not able to run this game at the same performance as Windows XP Professional for the same reasons that it was not able to run the Far Cry.

At this point, we will continue with some application tests to see if we have any performance changes when we run the same 32-Bit versions on each of the Windows versions and then to see the boost in performance when we use a 64-bit version of an application with Windows XP x64 against the 32-Bit version with Windows XP Professional.


14. Application Benchmarks - 3DMark2003

3D Mark is a widely used and accepted benchmark that stresses the DirectX performance of a VGA card. A very strong point of 3DMark is that it's VGA card measuring is does not require any CPU power. So the resulting fps are a good reference a VGA card's rendering performance. For testing the performance of each card we used the 4 game benchmarks 3DMark has.

3Dmark03 also includes sound and CPU tests as well as some other feature tests.

- Game Test 1 - Wings of Fury (DX7)

This test is a combat flight simulator written for older hardware (DirectX 7). Particles are used a lot in this test - smoke and vapor trails, flak and gunfire, and explosions are produced using point sprites and quads.

- Game Test 2 - Battle of Proxycon (DX8)

This test is a simulation of first person shooter game types. 1.1 and 1.4 Vertex shaders are widely used since all character models are skinned using vertex shaders.This makes this test a good vertex shader comparison for VGA cards.

- Game Test 3 - Trolls' Lair (DX8)

This test should be the favorite of all RPG lovers. It is a cut scene of a female warrior facing two malicious trolls. Again the same vertex and pixel processing is used as in game test 2.

This test also uses post-processing effects, such as Depth of Field and Bloom effects which are widely used in today's game cut scene sequences.

- Game Test 4 - Mother Nature (DX9)

Mother nature represents the level of effects and realism that are possible using 2.0 vertex and pixel shaders, plus some other features that DirectX 9 offers.

Windows XP x64 does a really good job in this test. The difference is barely noticeable. Below are the full games results. The results must be considered as identical because of the fact that 3DMark has a tolerance of ±2% and so the difference in the FPS could have swung either way.


15. Application Benchmarks - 3DMark2005

With 3DMark05, Futuremark continues the tradition in its benchmarking software by providing a state-of-the-art Microsoft ® DirectX ® 9 3D performance benchmark.
3DMark05 is an all new 3DMark version taking the most out of Microsoft's DirectX 9. The previous version 3DMark03, did a nice introduction into this level of technology. However 3DMark03 used DirectX 9 specific features in a limited manner, because fully supporting hardware was rare at the time of its launch. In contrast, 3DMark05 requires DirectX 9 hardware with full support for at least Shader Model 2, and takes shader usage to never before seen levels.
Just like its predecessors, 3DMark05's point system is set so that at the moment of release, the high-end VGA cards available in stores can only score around 5000 3DMarks, whereas the worst card that meets the programs requirements yields a score of 1000.

 

Game Test 1 -Return to Proxycon

Being the sequel to the "Battle of Proxycon" from 3DMark03, in "Return to Proxycon" we're once again set in space and the battle continues as space pirates invade a cargo ship in order to take control of its valuable cargo.

 

 

This test, tries to simulate a future first-person shooter game with all the high details that entails. The dynamic shadows, high-detailed environment and advanced lighting techniques ensure that under normal circumstances, no recent card can run it with decent frame rates.

Game Test 2 - Firefly Forest

A forest gets filled with magic fireflies in the night. The moon is nearly full, illuminating the forest with a bluish faint light. The magic fireflies have flickering bright green lights that playfully move around the forest.

This scene is a nice example of a smaller scale outdoor scene with rich vegetation. Immediate visibility is not so far, and there is a skybox surrounding the whole scene.

A large number of trees with their branches swinging separately, and dense vegetation being dynamically distributed according to the camera movements, make this test the most demanding of the three.

Game Test 3 - Canyon Flight

A Jules Verne type airship flies through a canyon guarded by a dangerous sea monster. The airmen defend their ship using heavy cannons, but these seem to have no effect on the huge sea monster. Finally the crew manages a narrow escape using the "last resort" afterburners of the airship.

This scene is fairly complex with large areas of water reflecting the high canyon walls. The water actually is one of the key points of interest in this scene. The water not only does realistic looking reflections and refractions, it has a depth fog, making the sea monster swimming under the airship actually look deep down in the water. The air in this scene also uses
a volumetric fog, making distant cliffs of the canyon really look far away.

Final Score

 3DMarks on 3DMark05 are now calculated by the following formula:

(Game Test 1 * Game Test 2 * Game Test 3)^0.33 * 250

Below we have the Total score for 3DMark 2005

Just as with 3DMark 2003, this test shows similar performance scores for both Windows versions. However, with Windows XP x64, we have a performance lead of approximately 3% allround.


16. Application Benchmarks - PCMark04

PCMark04 is an application-based benchmark and a premium tool for measuring overall PC performance. It uses portions of real applications instead of including very large applications or using specifically created code. This allows PCMark04 to be a smaller installation as well as to report very accurate results. As far as possible, PCMark04 uses public domain applications whose source code can be freely examined by any user.

PCMark04 includes 4 categorized suites for benchmarking your computer. These include a CPU, Graphics, Memory and a Hard Disk Drive benchmark.

We ran all the test for both operating systems.Here are the extended results:

The difference is unnoticeable with most of the PCMark04 tests.

Once again, the differences in the graphics tests puts Windows XP in 1st place because of the WOW64 emulator. Take a look at the results for the transparent windows test under the Graphics suite. In this test, 10 windows are drawn on-screen and then faded in and out. The results then record the average number of windows drawn per second.

In the memory and CPU tests, the differences is also not noticeable. With the HDD tests, we notice a performance increase with Windows XP Professional x64 Edition. This is because of the better memory handling of Windows XP Professional x64 Edition which we have already discussed.


17. Application Benchmarks - SiSoftware Sandra 2004

SiSoftware Sandra 2004

SiSoftware Sandra (the System ANalyzer, Diagnostic and Reporting Assistant) is an information & diagnostic utility. It should provide most of the information (including undocumented) you need to know about your hardware, software and other devices whether hardware or software.

CPU Arithmetic Benchmark

Sandra's CPU arithmetic benchmark suite uses 2 famous benchmarks (Dhrystone and Whetstone) for stress testing the processor. Also it includes a new version of the Whetstone test that makes use of a processor's SSE2 instructions to show the performance boost an application might gain should it be optimized for SSE2. Unfortunately this does not always represent a true real-life performance, but is useful to compare the speed of various CPUs.

The 64-Bit performance benefits in this test show only 65 iterations per second more with the SSE2 instructions and about 500 more for the Whetstone FPU (floating point) and Dhrystone (arithmetic) benchmark.

CPU Multimedia Benchmark

This test involves the generation of Mandelbrot Set fractals that are used to realistically describe and generate natural objects such as mountains or clouds. By using various multi-media extensions MMX, 3DNow! and SSE(2/3) better performance is achieved.

Here the benchmark takes advantage of the x8 SSE2 instructions for floating points and x16 SSE2 for integers, we managed to get about 5000 iterations per second less (about 23%) with integers and 2000 iterations more (about 9%) with floating point.

Memory Bandwidth Benchmark

This tests examines how your memory sub-system compares to other systems with the same or similar memory. The benchmark is based on the well-known STREAM memory bandwidth benchmark.(The main difference is that STREAM 2.0 uses static data (about 12M) but SiSoftware Sandra uses dynamic data (around 40-60% of physical system RAM). )

 

Although this test is highly dependent on the memory modules used, we observe slightly lower performance with Windows XP x64.

Cache & Memory Benchmark

This test is based on the Memory Bandwidth Benchmark test. The difference is that the memory index is lower as streaming/buffering/block pre-fetch is not used on this test to increase performance with small blocks (it is usefull only in large amounts of data)

Combined Index: is a composite figure representing the overall performance rating of the entire Cache-Memory performance in terms of MB/s. The value is a result of the logarithmic average of all the results for the entire address space.Here we notice a small lead for windows XP x64

Speed Factor: Represents the speed differences between the CPU's cache and memory. The value is a result of the ratio of the fastest cache (for example L1) bandwidth to the main memory bandwidth, which means that the lower the result, the better for us. Here we have Windows XP professional lagging behind by about 20%.

HDD Benchmark

This Benchmark is a composite figure representing an overall performance rating based on the average of the read, write, and seek tests, and file and cache size. It is intended to represent hard disk drive performance under typical use in a PC. A larger number means better performance. The weighting of the results is not equal that it represents the distribution of different files sizes as used on these devices (obtained through field research).

Combined Index: is a composite figure representing an overall performance rating based on the average of the Combined Index figures over the four file sizes. This test measures the time that 4 files of the following size: 512 Bytes, 32KB, 256KB and 2MB can be read, written and deleted (the number of files per minute). Windows XP x64 shows a performance lead of about 5000 operations per minute.


18. Application Benchmarks - Science Mark 2

Science Mark 2.0 is an attempt to put the truth behind benchmarking. In an attempt to model real world demands and performance, SM2 is a suite of high-performance benchmarks that realistically stress system performance without architectural bias. Synthetic benchmarks are useful, and can tell the user valuable performance characteristics about their system's performance, but they should not be used in entirety to measure system performance; this role is reserved in greater part to real applications performing real tasks. Science Mark 2.0 is comprised of 7 benchmarks, each of which measures a different aspect of real world system performance. According to sciencemark.org, the codes in Science Mark 2.0 were architected with general system performance considerations before they were implemented.

Let's take a more detailed look at each benchmark test and what it does:

"MemBench" - An unbiased, synthetic benchmark that sweeps through more than 15 different, publicly available, memory copy algorithms to measure the peak memory performance of your CPU’s caches and your memory subsystem.

"BlasBench" - Scientists and engineers use large matrix multiplication to determine peak MFLOPS. BlasBench measures the MFLOPS of your machine via large matrix multiplication. The benchmark can be run in single or double precision. Real world matrices are often large and don't fit into the processor's cache. Science Mark 2’s optimized implementations of matrix multiplication in single and double precision, from an algorithm point of view, perform remarkably better than the blind man's matrix multiplication routine. BlasBench uses building blocks called kernels at its lowest level that determine overall MFLOPS performance. These kernels are written in C and a wide assortment of assembly forms (SSE Vector, SSE2 Vector, SSE2 Scalar, x87, 3DNow! Vector) to support any processor architecture in the x86 market.

"MolDyn" - Science Mark 2.0 performs Molecular Dynamics Simulations. It has the flexibility of simulating any 5 noble gases, in 3 different crystallographic configurations, with variable numbers of atoms at a user specified temperature.

"Primordia" - Science Mark 2.0 computes the electronic orbitals for the atoms between Hydrogen and Promethium in the periodic table using a Restricted Hartree-Fock method. Primordia outputs the total all electron energy of the atom in addition to the kinetic and potential contributions. The user is allowed to specify different grids upon which the orbitals are determined.

"QMC" - The Primordia orbitals are utilized to simulate and determine the properties of molecules using the extremely accurate quantum Monte Carlo algorithm. Primordia and QMC are indicative of what is done in commercial chemistry codes on workstations and supercomputers about the world.

"FEM" - The behavior and properties of fluids and structures is modeled using the Finite Element Method. Similar tasks are performed by automotive, aerodynamic and civil engineering companies during their product design.

"Cipher" - Benchmark tests four different forms of encryption algorithms, AES 128/256 bit and RSA 512/1024 bit. Sean's AES 128 bit encryption algorithm is quite possibly the fastest implementation on the face of the earth.

Score is weighted thus:

(((Memory Score + Stream Score) / 2) + Cryptography Score + Molecular Dynamics Score + Primordia Score + BLAS Score) / 5

Unfortunately the final version of ScienceMark 2 for Windows x64 Edition is still beta. According to the developer, performance may change in the future depending on how they tune for fp performance. We should see significant speedups on both EM64T and AMD64 processors in 64-Bit mode. Part of this will be due to compiler improvements. : Intel EM64T systems are supported, however, ScienceMark2 won't be able to detect them properly in MemBench at this time. This will be remedied in a future version. Also, CipherBench is not supported in 64-Bit mode at this time. This will be remedied in a future version. The graph below shows us the results of the 32-Bit version of this program that we ran under Windows XP Professional and the results of the 64-Bit version that we ran under Windows XP Professional x64 Edition.

As we mentioned before, the Cryptography Benchmark (CipherBench) is not available at this time for the 64-Bit version of this program. This is the first test where we use a 64-bit version and we managed to see significant performance increases. In the molecular Dynamics Benchmark, notice the awesome performance difference of 49%. We can understand that this result is due to the fact that in the 64-Bit architecture, a lot of procedures are completed in less time. Also, in the Primordia test, we have an increase of 9%.

However, in the BLAS/FLOPs test we can see that the Windows XP x64 drops to under 35% but if we consider that this is still a beta program we can expect improvements in a future, stable release. (The improvements of course will concern improved scores and not the opposite).


19. Application Benchmarks - Pov-Ray

The Persistence of Vision Ray-Tracer (Pov-Ray) creates three-dimensional, photo-realistic images using a rendering technique called ray-tracing. It reads in a text file containing information describing the objects and lighting in a scene and generates an image of that scene from the view point of a camera also described in the text file. Ray-tracing is not a fast process by any means, but it produces very high quality images with realistic reflections, shading, perspective and other effects.

What is Ray-Tracing?
Ray-tracing is a rendering technique that calculates an image of a scene by simulating the way rays of light travel in the real world. However it does its job backwards. In the real world, rays of light are emitted from a light source and illuminate objects. The light reflects off of the objects or passes through transparent objects. This reflected light hits our eyes or perhaps a camera lens. Because the vast majority of rays never hit an observer, it would take forever to trace a scene.

Ray-tracing programs like POV-Ray start with their simulated camera and trace rays backwards out into the scene. The user specifies the location of the camera, light sources, and objects as well as the surface texture properties of objects, their interiors (if transparent) and any atmospheric media such as fog, haze, or fire.

For every pixel in the final image one or more viewing rays are shot from the camera, into the scene to see if it intersects with any of the objects in the scene. These "viewing rays" originate from the viewer, represented by the camera, and pass through the viewing window (representing the final image).

Every time an object is hit, the color of the surface at that point is calculated. For this purpose rays are sent backwards to each light source to determine the amount of light coming from the source. These "shadow rays" are tested to tell whether the surface point lies in shadow or not. If the surface is reflective or transparent new rays are set up and traced in order to determine the contribution of the reflected and refracted light to the final surface color.

Special features like inter-diffuse reflection (radiosity), atmospheric effects and area lights make it necessary to shoot a lot of additional rays into the scene for every pixel.

The below graph displays the time in seconds that the program have to run in order to complete the test.

We have also selected this test not only because it is one of the few available for the 64-bit version, but because we want to examine the benefits of the 64-bit architecture regarding rendering images and complex textures while using effects.

In the test, we selected a resolution of 1280x1024 with an antialiasing threshold value up to 0.3 (to speed up antialiasing, a threshold value is used between pixels. If the difference in color between two pixels is higher than the threshold, then antialiasing is calculated). Parse time is the time it takes to parse the project, photon time it takes to render the Photon map. The photon map is used to render true reflective and refractive caustics by shooting packets of light (photons) from light sources into the scene. The Average Render is the average PPS (pixels per second) that the render took.

With Windows XP x64, rendering was finished 7 minutes faster (30 minutes for Windows XP Professional and 23 for Windows XP x64) which makes it 23% faster than Windows XP Professional.


20. Conclusion

Windows XP Professional x64 Edition is an operating system with a lot of opportunities. Currently, there aren’t a lot of users that really need this release, but in the future memory capacities will have reached such high levels that it will be necessary. Programmers, web designers, 3D animators to gamers, all will need this.

According to Bill Gates, Microsoft is going to continue supporting this operating system as well as Windows XP (Professional and Home Edition) for another 10 years. This is because Windows XP is the most successful operating system. Moreover, a lot of the features of the “Next Generation” operating system Longhorn, will be made available in the future for the Windows XP and Windows x64 versions through patches.

Considering this, then it is a very good move to choose to buy this version over other releases. We still recommend you that if you choose to install this operating system, that you create a second partition or install a second hard disk drive to avoid any problems.

Performance Changes

From our tests, we have come to the conclusion that with the new operating system, current 32-bit applications (including games) will have a performance decrease of 1% - 8% although in some special cases there may also be a performance increase of 5%. The benefits of the 64-bit architecture come into their own with 64-bit applications where we managed to see over 49% performance increase and there is still room for improvement. The ability to simultaneously run more applications than ever before, makes this release necessary for the power users.

Security and Compatibility

Considering that there are not a lot of antivirus programs available for this OS at this time, we would suggest you not use this version for surfing on the Internet, especially if you have important documents on your machine that you don't want to lose.

Final words

Microsoft believes that by the end of 2005, all new server class machines shipping will be 64-bit and at the end of 2006, the majority of new PCs and workstations will be 64-bit. This is logical if we consider that the price range will be at the same level as for Windows XP Professional of Home versions and that there are a lot of 64-bit processors to choose from, so Windows XP x64 will dominate in the end. It is the prelude to what will happen when Windows Longhorn Final version is released.

We still suggest you install in a separate partition or on another hard disk drive to avoid compatibility problems, and to check our list for available drivers and the available programs that are supported for now. It will take some time before this will be a 100% safe OS to install, replacing your older Windows. Don't forget to take a look at microsoft.com for more information and how to buy Windows XP Professional x64 Edition.
