Inno3D GTX 580 OC

1. About Nvidia's GTX 580 GPU

Nvidia has finally released the highly anticipated GeForce GTX 580 graphics card. As card based on a new GPU, the GF110, the GTX 580 comes to replace the GTX 480 and also perform better, as the GF110 is more complete and most importantly, it comes with all its features enabled. Remember that the GTX 480 and GF100 were not exactly the the products that NVIDIA first envisioned. Generally, the GF100 shipped through many Nvidia cards had not all of their SMs enabled.

The new GF110-powered GeForce GTX 580 is using around 3 billion transistors, which is the same as the GF100 featured. However, the GF100 comes with all the available L2 cache, ROPs and all the SMs enabled. These are translated in a 6.6% more shading, texturing, and geometric performance for the GTX 580 compared to the GTX 480 at the same clockspeeds.

With GTX 580 taking the $500 spot , Nvidia's GTX 480 will retail at around $400-$420, and the GTX 470 is available at $239-$259, still competing with the AMD Radeon HD 6870. Speaking about AMD, the company does not have a direct competitor for the GTX 580 at the moment, besides the Radeon HD 5970. This is expected to change soon as AMD will release its Cayman GPUs by the end of the year.

The GF110 features 512 CUDA Cores divided up among 4 GPCs, and in turn each GPC contains 1 raster engine and 4 SMs. At the SM level each SM contains 32 CUDA cores, 16 load/store units, 4 special function units, 4 texture units, 2 warp schedulers with 1 dispatch unit each, 1 Polymorph unit (containing NVIDIA’s tessellator) and then the 48KB+16KB L1 cache and registers. This architecture is not very different than what we saw with the previous GF100 GPU, at least for the computing side.

The real change comes on the graphics side. GF104’s texture units improved this to 4 samples/clock for 32bit and 64bit, and it’s these texture units that have been brought over for GF110. GF110 can now do 64bit/FP16 filtering at full speed versus half-speed on GF100. In addition, the GF104 doubled up on texture units while only increasing the shader count by 50%.

The card also features a new high-speed 32x anti-aliasing for keeping the rough edges smooth as well as a new tesselation approach.

The result is what Nvidia call's "the world's fastest DirectX 11 GPU."

Beyond the specific architectural improvements for GF110, NVIDIA has also been tinkering with their designs at a lower level to see what they could do to improve their performance. The company looked at GF110 at a transistor level, and determine what they could do to cut power consumption. So the GF110 includes a new type of transistor, which has better characteristics than those used for the GF100. The result was a lower power consumption without sacrificing performance.

Attached to GTX 580 are also a series of power monitoring chips, which monitor the amount of power the card is drawing from the PCIe slot and PCIe power plugs. By collecting this information NVIDIA’s drivers can determine if the card is drawing too much power, and slow the card down to keep it within spec.

Nvidia's new offering also runs quieter with its vapor chamber thermal design. The combination of the new vapor chamber thermal solution and new architectural enhancements make the GTX 580 the fastest and quietest GPU in its class, delivering an increase of up to 35 percent in performance per watt, and performance that is up to 30 percent faster than the original GeForce GTX 480.

 

It's time now to see the specifications of the GTX 580. Nvidia released the product with 512 CUDA cores, with a Graphics clock / Processor clock of 772 / 1544 MHz, 1.5GB / 384-bit GDDR5 onboard and a memory speed of 4.0 Gbps:
