SAPPHIRE has officially announced the HD 7950 Mac Edition, a new
graphics accelerator compatible with the Apple Mac Pro series of
desktop computers.
The HD 7950 Mac Edition is based on AMD's latest Graphics Core Next
(GCN) architecture. SAPPHIRE claims that the new card
delivers a significant graphics performance boost for Mac Pro users
in a wide range of applications including gaming, audio or video
editing and content creation. For example, gaming frame rates are
increased by over 200%, general benchmark performance increased by
around 30% and graphics intensive benchmarks increased by as much
as 300% compared with the NV 8800GT commonly used in these
machines.
The SAPPHIRE HD 7950 Mac Edition is equipped with 3 GB of GDDR5
memory, and its Dual Asynchronous Compute Engines (ACE) deliver up
to 2.87 TFLOPS Single Precision compute power. It provides hardware
support for Open GL 4.2 and Open CL 1.2 as well as AMD HD3D
technology and APP acceleration.
AMD's GCN architecture supports a number of post-processing and
scaling operations. These include de-blocking, de-noising,
automatic de-interlacing, Mosquito noise reduction and edge
enhancement as well as image quality enhancement technology, such
as adaptive anti-aliasing and 16x angle independent anisotropic
texture filtering. The SAPPHIRE HD 7950 Mac Edition features AMD
PowerPlay technology which provides automatic power management
during operation and ensures low power consumption under idle
conditions.
Integrated display support includes two mini DisplayPort outputs
with a maximum resolution of 3840 x 2160 per display under MacOS X.
The card also features a 3 GHz HDMI 1.4a port. This output also
supports a maximum resolution of 3840 x 2160.
Finally, there is a Dual-link DVI port with HDCP, which supports a
maximum resolution of 2560 x 1600. As this is a DVI-I port it can
also be used with the older style VGA monitors, with adapter
supplied. The card supports two display outputs to be used at the
same time, allowing dual monitor configurations to be used for
increased productivity.
The SAPPHIRE HD 7950 Mac Edition is compatible with Apple Mac Pro
models from 2010 and later with an available PCI-Express x16 slot.
Two six-pin power cables required are supplied with the card. A
driver disk is provided which enables the card to be used with Mac
OS X 10.7.5 (Lion), 10.8.2 (Mountain Lion) or later.
The SAPPHIRE HD 7950 Mac Edition can also be used in the latest PC
architectures. It has Dual Firmware support via a simple Firmware
(Dual BIOS) switch. In one position the Sapphire HD 7950 MAC
Edition supports Mac OS X/Windows under non-UEFI compliant mode and
in the other it supports Windows with UEFI hybrid firmware enabled.
A Windows driver disk is also included.
Under Windows, additional features are supported, including
hardware acceleration of video decoding, HDMI audio pass through
and additional display resolutions. |
