Notas de Rodapé 

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

Reviews 

AnandTech.com “…with the 7750 coming in at 104W at the wall and the 7770 at 106W. AMD’s continuing efforts to reduce idle power consumption are clearly paying off, making this the lowest idle power usage figures we’ve recorded yet.” - Ryan Smith, AnandTech

HardOCP.com “…if you have anything under a GTX 560 Ti like a GTX 550, or 550 Ti or 560 non-Ti, then the Radeon HD 7770 would be an upgrade.” –B. Justice, HardOCP “The HD 7770 delivers the same gameplay experience as a GTX 560 Ti, and is less expensive” –B. Justice, HardOCP “The Radeon HD 7770 video card is absolutely perfect for 1080p displays, or displays capable of 1920x1200. In every game we tested here today we had no need to drop below 1920x1200 resolution to scale up in-game eye candy.” –B. Justice, HardOCP

HotHardware.com “All told, the Radeon HD 7700 series cards look solid at their respective price points and are certainly worthy of consideration if you’re in the market for an affordable GPU.” -M. Chiappetta, HotHardware

LegitReviews.com “The most impressive areas of Cape Verde were without a doubt the series power efficiency. AMD has a very efficient design here that doesn't require much power and therefore doesn't produce much heat. That leads to power savings, lower temperatures and GPU cooling solutions that don't make much noise.” –N. Kirsch, LegitReviews

PCPerspective.com “As it stands today the Radeon HD 7770 is the most power efficient card at the $160 price point…” –R. Shrout, PC Perspective

Rage3d.com “The AMD Radeon HD 7700 series should be the default choice for the majority of upgraders, system builders and value-added resellers who are looking for the best balance of power and performance today's most common resolutions, supporting the latest features and standards.” –J. Prior, Rage 3D
