 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. | Interface | PCI Express 16x 3.0 | | Chipset | ATI Radeon HD7950 | | Memory | 3Gb DDR5 | | Core Clock | 900Mhz | | Memory Clock | 5000Mhz (1250Mhz DDR5) | | VGA (Max Res) | Supported by Included DVI to VGA Adapter | | DVI (Max Res) | 1 DVI Port (2560 x 1600)

 | 28 nm GCN (Graphic Core Next) Architecture The new and 28nm GCN Architecture with more efficient process technology puts more transistors in less space, enabling a dramatic increase in Processing Power. Crank the settings, devastate your enemies and bear witness to absurdly high frame rates with AMD Radeon HD7000 series graphics card-DirectX 11 has never looked this good. Maximum setting and crazy performance shouldn’t be a compromise. The AMD Radeon HD7900 Series with the new 28 nm GCN Architecture assures that it’s not. |
|
 | 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. |
|
 | AMD Eyefinity 2.0 The next generation of AMD Eyefinity technology is here, featuring all-new support for stereo 3D, universal bezel compensation and brand new display configurations. Face it: the best just got better: The enhancements for AMD Radeon HD7000 series include: Stereo 3D-multi-display stereoscopic 3D support via DisplayPort 16K X 16K maximum display group resolution-output up to 268 megapixels per GPU.
*To support 3 displays, one of the monitors has to support DisplayPort
**When running Microsoft Windows XP, Eyefinity technlogy supports a maximum of 2 displays.

|
 | Enhanced Multi-GPU Capabilities Triple or quadruple gaming power with AMD CrossFireX Multi-GPU technology. Increase your gaming performance up to 2x with AMD CrossFire technology, 2.75x for TriFire configurations, or with QuadFire configurations. With AMD ZeroCore Power Technology, the graphics card in slave modes will be switched off in idle to maximize the power saving. |
|
 | 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. |
|
 | Microsoft DirectX® 11 Get intense gaming performance and unrivalled image quality with stunning 3D visual effects, realistic lighting and lifelike imagery with SAPPHIRE graphics cards supporting DirectX®11. New features in DirectX®11 such as Hardware Tesselation, HDR Texture Compression, Multi-threading support and DirectCompute bring lifelike gaming and an experience never possible on a PC before. |
|
 | 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 5.0Q |
 | 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) |
|
 | Display Flexibility Offers an incredible choice of the latest display connectivity options natively on the board, including dual-link DVI-I, DisplayPort and HDMIalong with adapters to ensure compatibility with your legacy analogue VGA monitor.
|
|
 | TriXX Utility TriXX helps users to get the optimum performance from compatible SAPPHIRE graphics cards in any application by allowing them to monitor, tune and save different settings of key parameters for the card. | | |
 | AMD PowerPlay with ZeroCore Power Technology AMD PowerPlay is a power management technology in response to the GPU loading, AMD PowerPlay automatically manages the power consumption. AMD RADEON HD7000 Series with AMD ZeroCore Power Technology, the power consumption can be as low as less than 3 Watt when idle, making the best use of power. |
|
 | Accelerated Internet Applications Rendering The new AMD Radeon HD 7000 Series accelerates the rendering performance with the latest web browsers (IE10, Firefox 6) and programming interfaces (Direct2D, HTML5, WebGL, Flash 11 / Molehill). |
|
 | AMD HD Media Accelerator AMD HD Media Accelerator has been designed to help optimize and dramatically improve video playback on your computer by taking advantage of hardware video acceleration from your AMD Radeon GPU. With full 3D stereoscopic decode you can enjoy it all in 3D. AMD HD Media Accelerator speeds up the decode of one 1080p and one 1080i HD video streams simultaneously by hardware, and the new hardware encodes/transcoder processes your media content faster than ever! |
|
 | Cutting-edge Quad HD display support (4K Support) The display resolution on AMD Radeon HD7000 series is quadrupled to the resolution of 4KX2K( 4096X2160 ) from the outputs of DisplayPort 1.2 and HDMI. |
