The Radeon R7 200 series are designed for DirectX 11 and Windows 7. AMD is also supporting DX12 with the R7 200 series.

r7-240GCN

The AMD Radeon R7 200 series are all made at 28nm and use the new AMD graphics core next architecture (GCN) which is intended to make it easier to design general compute cards looking forward.

AMD cards can now be looked at by the number of GCN units in the card as opposed to the number of unified shaders. Each GCN module has 64 shaders and the new architecture can now assemble large numbers of these in parallel to improve rendering performance.

GCN works well for DX11 and DX12 and other APIs. each GCN module can work on a separate API towards the complete image.

GAMES

The R7 220 is 500 GFLOPS and the rest are even more powerful. See the page on system requirements for better background information. Generally these cards dramatically more powerful than the R5 200 series. The R7 200 series can handle most games at 1280×720 and 1920×1080.

The Radeon R7 240  can all handle games from the Xbox / PS2 period generally. The more powerful Radeon R7 265 can all handle games from the Xbox 360 / PS3 period generally.
