Radeon HD 2900 XT 512MB Game Requirement Analysis
Radeon HD 2900 XT 512MB is a high-end GPU based on the 80nm variant of the second unified shader architecture, R600.
It's based on the R600 XT Core and offers 320 Shader Processing Units, 16 TMUs and 16 ROPs on a 512-bit memory interface of standard GDDR3. The central unit runs at 743MHz and the memory clock runs at up to 828MHz.
Its performance is somewhat faster than Radeon HD 2900 Pro due to being higher clocked and the extra memory bandwidth is bottlenecked by the small sized frame buffer and thus most games have to be played using a 1024x768 resolution but should be playable at high settings.
