Sapphire Radeon X800 GT

SaphhireRadeonx800GT.jpgThe eight pixel-pipeline GPU in Sapphire’s Radeon X800 GT is clocked slightly slower than the GeForce 6600 GT in Leadtek’s card (486- vs. 500MHz), but its memory configuration more than compensates for the difference: Sapphire’s card is not only equipped with twice as much GDDR3 memory as Leadtek’s, but the GPU’s 256-bit memory interface is twice as wide. This helps explain Sapphire’s superior benchmark performance in nearly every category.

ATI will eventually ship its CrossFire dual-GPU solution, but from what we understand of ATI’s technology, it wouldn’t use the X800 GT card in a CrossFire configuration. Here’s why: The CrossFire Edition boards will achieve parity with whatever card they’re paired with, so if you couple a 128MB X800 CrossFire Edition card with the X800 GT, half the X800 GT’s frame buffer will be wasted. Pair the card with a 256MB X800 XL CrossFire Edition, and half the CrossFire’s pixel pipelines will shut down.
