Tech Specs
The X800XL is based on ATI's R430 graphics core. Its primary distinction between ATI's other R4x0 cores is that it's built on an 110nm manufacturing process whereas ATI's other cores are built using a 130nm low-k process. It's a native PCI-Express chip.
Sapphire's X800XL Ultimate has a core clock speed of 400MHz and a memory speed of 490MHz (980MHz effective), typical of X800XL cards. It has 256MB of GDDR3 memory from Samsung rated for 2.0ns, or 500MHz maximum. It also has 16 rendering pipelines, 6 vertex shader units, and a 256bit memory bus.
