Radeon X1800 XL Game Requirement Analysis
Radeon X1800 XL is a performance GPU based on the 90nm variant of the R500 architecture.
It's based on the R520 Core and offers 16 Pixel Shaders, 16 TMUs and 16 ROPs, on a 256-bit of standard GDDR3. The central unit runs at 500MHz and the memory clock operates at up to 500MHz.
Its performance is considerably better than Radeon X1800 GTO thanks to core configuration, as is the power consumption.
Some of today's games might be playable at medium settings although the low preset will have to be used on most. As it's not based on a Shader-Unified architecture, both DirectX 10 & 11 games aren't supported.
