Radeon HD 2600 XT 256MB GDDR4 Game Requirement Analysis
Radeon HD 2600 XT 256MB GDDR4 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 energy efficient GDDR4. The central unit runs at 800MHz and the memory clock runs at up to 1100MHz.
Its performance is quite superior to Radeon HD 2600 Pro due to being much higher clocked and featuring GDDR4 but only slightly faster than the Radeon HD 2600 XT GDDR3 variant while consuming extra power.
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.
