Footnotes 

Additional hardware (e.g. Blu-ray drive, HD or 10-bit monitor, TV tuner) and/or software (e.g. multimedia applications) are required for the full enablement of some features. Not all features may be supported on all components or systems - check with your component or system manufacturer for specific model capabilities and supported technologies.

1. Based on GCN Architecture, the world’s first 28nm graphics architecture, the AMD Radeon™ HD 7970 and HD 7950 graphics achieve 3DMark® 11 scores in excess of X2700 and X2200, respectively. These results are the two highest scores achieved by single-GPU graphics cards on stock platforms as of 26 January, 2012. System configuration: Intel Core i7-3960X (3.3GHz), MSI X79A-GD65 8D, 16GB DDR3-1600 (9-9-9-24) and Windows® 7 64-bit. Testing based on AMD Catalyst™ 8.921.2. The NVIDIA® GeForce® GTX 580, NVIDIA’s highest performing single-GPU graphics card, was evaluated using NVIDIA ForceWare 290.53 BETA and scored X2124.
2. Utilization of PCI Express 3.0 bandwidth requires a mainboard equipped with a PCI Express 3.0 PHY. Not all mainboards feature this technology – check with your component or system manufacturer for specific model capabilities.
3. AMD Eyefinity technology works with games that support non-standard aspect ratios, which is required for panning across multiple displays. To enable more than two displays, additional panels with native DisplayPort™ connectors, and/or DisplayPort™ compliant active adapters to convert your monitor’s native input to your cards DisplayPort™ or Mini-DisplayPort™ connector(s), are required.  Support for six simultaneous displays may require complementary products compatible with DisplayPort 1.2 Multi-Stream Transport. Maximum number of configured displays may vary - check with your component or system manufacturer for specific model capabilities and supported technologies.  SLS (“Single Large Surface”) functionality requires an identical display resolution on all configured displays.
4. AMD HD3D is a technology designed to enable stereoscopic 3D support in games, movies and/or photos. Requires 3D stereo drivers, glasses, and display. Not all features may be supported on all components or systems – check with your component or system manufacturer for specific model capabilities and supported technologies. A list of supported stereoscopic 3D hardware is available at http://www.amd.com/HD3D.
5. AMD CrossFire™ technology requires an AMD CrossFire Ready motherboard, an AMD CrossFire™ Bridge Interconnect (for each additional graphics card) and may require a specialized power supply.
6. AMD PowerPlay™ and AMD PowerTune are technologies offered by certain AMD Radeon™ products, which are designed to intelligently manage GPU power consumption in response to certain GPU load conditions. Not all products feature all technologies – check with your component or system manufacturer for specific model capabilities.
7. AMD App Acceleration is a set of technologies designed to improve video quality and enhance application performance. Full enablement of some features requires support for OpenCL™, DirectCompute or DirectX® Video Acceleration (DXVA). Not all products have all features and full enablement of some capabilities and may require complementary products.
