Radeon HD 2900 GT Game Requirement Analysis
Radeon HD 2900 GT is a high-end GPU based on the 80nm variant of the second unified shader architecture, R600.
It's based on the R600 GT Core and offers 240 Shader Processing Units, 12 TMUs and 12 ROPs a 256-bit memory interface of standard GDDR3. The central unit runs at 600MHz and the memory clock runs at up to 800MHz.
Its performance is not comparable to neither Radeon HD 2900 Pro nor Radeon HD 2900 XT due to featuring only 240 Shader Processing Units. Still, it's clearly above Radeon HD 2600 GPUs.
Due to the limited memory size, most of today's games will require unattractive resolutions but should run fluently from medium to high settings at anything below 1024x768.
