AMD announced its most important GPU for the season, the Radeon R9 285. The chip is designed to compete with the GeForce GTX 760 from NVIDIA at not just performance, but also energy-efficiency, and low component costs, so AMD can price it better. Based on a brand new 28 nm silicon by the company, codenamed "Tonga," the R9 285 features 1,792 Graphics CoreNext 1.2 stream processors, 112 TMUs, 32 ROPs, and a 256-bit wide GDDR5 memory interface, holding 2 GB of memory.

AMD partners are free to come up with 4 GB variants. The card supports DirectX 12, OpenGL 4.4, and Mantle. It features new AMD innovations, such as XDMA CrossFire, TrueAudio DSP, and 4-display Eyefinity by plugging into every connector on the card (two dual-link DVI, one DisplayPort 1.2, and one HDMI 1.4a). The card draws power from a pair of 6-pin PCIe power connectors. Available now, the Radeon R9 285, from various AMD partners starts at US $249.
