Radeon X1900 GT Game Requirement Analysis
Radeon X1900 GT is a high-end GPU based on the 90nm variant of the R500 architecture.
It's based on the R580 Core and offers 36 Pixel Shaders, 12 TMUs and 12 ROPs, on a 256-bit of standard GDDR3. The central unit runs at 575MHz and the memory clock operates at up to 600MHz.
Its performance is relatively average but just about 1% faster than Radeon X1800 XT.
Most of today's games might be playable at medium settings although the low preset will have to suffice on some. As it's not based on a Shader-Unified architecture, both DirectX 10 & 11 games aren't supported.
