AMD has officially revealed the Radeon R9 Nano, a quiet and power efficient graphics card designed for small form factor PCs. Measuring about six inches in length, the Radeon R9 Nano uses High-Bandwidth Memory (HBM), and features 30 percent more performance and 30 percent lower power consumption (175W) than the AMD Radeon R9 290X card. This enables gaming enthusiasts and modders to build compact entertainment systems with enough power to deliver 4K gaming to their living room televisions along with VR experiences.

First shown at E3 2015, the Radeon R9 Nano uses the graphics chip codenamed "Fiji," and will be available starting September 7, 2015 for about $649 US. The compact video card will support DirectX 12, AMD Eyefinity, AMD Crossfire, AMD FreeSync, AMD LiquidVR, and 4K Resolution.
