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. 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.
2. 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.
3. 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.
4. 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.
5. AMD PowerPlay™, AMD ZeroCore Power 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.
6. 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.
7. Minimum recommended system power supply wattage is based on the specific graphics card and the typical power requirements of other system components. Your system may require more or less power. OEM and other pre-assembled PCs may have different power requirements.

Reviews 

HardOCP.com “…we feel the Radeon HD 7870 has earned our [H]ardOCP Editor's Choice Silver award, it is a very good video card that we are impressed with.” –B. Justice, HardOCP . HardwareCanucks.com “If you are in the market for a sub-$400 GPU or are looking to step up from a HD 5800-series product, the HD 7870 2GB is the card you'll want to pick up. It has all the makings of a success story: great performance, a relatively affordable price, low power consumption, quiet operation and plenty of overclocking headroom.” – M. Hoenig, Hardwarecanucks HotHardware.com “…the Radeon HD 7800 series appears solid. The cards performed well and they ran relatively cool and quiet.” -M. Chiappetta, HotHardware LegitReviews.com “Considering how fast, quiet, overclocking friendly and power efficient the Radeon HD 7870 GHz Edition is, we can see this card selling very well. Overclocked up to 1.2GHz this card screamed and was an impressive DX11 graphics card.” –N. Kirsch, LegitReviews PCPerspective.com   Rage3d.com “If you're still holding on to a DX10 card, or have a first generation DX11 card, the combination of performance and power efficiency in the AMD Radeon HD 7800 series should be a compelling offering for you…” –J. Prior, Rage 3D The Tech Report “And, again, the Radeons are way more power-efficient.” [than the comparable GeForces] – Scott Wasson, The Tech Report “The Radeon HD 7870 and 7850 are the most power-efficient of the bunch, but why wouldn't they be? They both have small and nimble 28-nm GPUs, while our other cards must make do with larger, more power-hungry 40-nm chips.” – Scott Wasson, The Tech Report “Without overvolting, we succeeded in running the Radeon HD 7870 at 1200MHz with its memory chugging along at 1375MHz.” – Scott Wasson, The Tech Report
