The SAPPHIRE HD 7950 OC Edition, which is factory overclocked to 900Mhz and features SAPPHIRE’s new dual-extractor technology - Dual-X - a highly efficient multi heatpipe cooler with dual fans providing quiet and very cool operation during normal operating conditions, and superb cooling performance even under extreme load. For enthusiasts wishing to maximise performance, a new version of the SAPPHIRE overclocking tool, TriXX supporting this latest generation of technology is available free to download from the SAPPHIRE website. TriXX allows tuning of GPU voltage as well as core and memory clocks, whilst continuously displaying temperature. Manual control of fan speed is supported, as well as user created fan profiles and the ability to save up to four different performance settings. Both of the SAPPHIRE HD 7950 models have a dual BIOS, allowing for further experimentation by the enthusiast. On the OC edition, the second BIOS is pre-programmed to allow a higher maximum overclock and more aggressive fan profile.
Equipped with the most popular Dual Link DVI (Digital Visual Interface), this card is able to display ultra high resolutions of up to 2560 x 1600 at 60Hz.
HDMI (with 3D)
Support for Deep Color, 7.1 High Bitrate Audio, and 3D Stereoscopic, ensuring the highest quality Blu-ray and video experience possible from your PC.
Enjoy the benefits of the latest generation display interface, DisplayPort. With the ultra high HD resolution, the graphics card ensures that you are able to support the latest generation of LCD monitors.
Doubling the effective bandwidth of previous DisplayPort implementations, DisplayPort 1.2 now includes support for Multi-Stream, allowing you to drive up to four separate monitors from a single DisplayPort 1.2 connector (requires DP1.2 monitors or Multi-Stream compatible hub), Stereoscopic 3D monitor support and adds support for high quality, lossless, 7.1 channel audio formats.
Advanced GDDR5 Memory Technology
GDDR5 memory provides twice the bandwidth per pin of GDDR3 memory, delivering more speed and higher bandwidth.
AMD HD3D Technology
Enjoy the most immersive experience possible with full support for High Definition Stereoscopic 3D, a technique that presents 2D images (movies, games, photos) in a format that creates the illusion of three-dimensional depth when using compatible 3D displays / glasses / software.
PCI Express 3.0
PCI-Express 3.0 delivers double the bandwidth per lane of PCIe Gen 2 for faster GPU (GPU communication-up to 16GB/sec in each direction), maximizing the performance from your GPU when paired with the latest platforms.
Discrete Digital Multi-Point Audio
The AMD Redeon HD 7900 Series is the first GPU that can simultaneously output multiple and discrete audio streams via HDMI and DisplayPort Output.
Supports the latest OpenGL API (Application Programming Interface) to accelerate performance of applications outside of DirectX®, i.e. Adobe Autodesk 2D/3D graphic design.
Shader Model 5.0
Supports the latest Shader Model 5.0 feature set including VTF (Vertex Texture Fetch) which is a key feature used extensively in many of the games that ship today. Without support for this feature the game will fall back to a lesser shader path resulting in the loss of cool, lifelike effects made possible by Shader Model 5.0.
AMD Catalyst Control Center
The AMD Catalyst Control Center™ software application gives you complete control over the performance and visual quality of your SAPPHIRE AMD Radeon™ based graphics card allowing for the best experience on your PC.
Dolby® TrueHD and DTSHD Master Audio Support
Support for copy protected, high bandwidth, 7.1 channel surround sound over HDMI. Get a fully immersive, high definition audio experience with the latest Blu-ray movies. (Requires a DVI to HDMI dongle on some models, an HD capable monitor and a Blu-ray drive)
