Radeon HD 2600 Pro Game Requirement Analysis
Radeon HD 2600 Pro is a middle-class GPU based on the 65nm variant of the second unified shader architecture, R600.
It's based on the RV630 Core and offers 120 Shader Processing Units, 8 TMUs and 4 ROPs a 128-bit memory interface of standard DDR2. The central unit runs at 600MHz and the memory clock runs at up to 500MHz.
Its performance is, overall, below the average and so today's games are only playable at unattractive resolutions and using low (on some) or medium (maybe) presets and DirectX 11 games aren't supported.
