Fillrate and shading
All four cards in this premium line-up sport a 16-pipe rendering setup, more shading power than is healthy, and 256-bit memory interfaces that deliver well over 30GB/s of juicy bandwidth to even the slowest card of the bunch, a GeForce 6800 GT. I took a brief look at shading and fillrate power, via 3DMark03, to see how NVIDIA and ATI's best stack up.
Pretty healthy single-texturing performance from all cards, with Gainward's souped-up GT taking top honours.
The common multi-texturing scenario sees all NV40-based cards take a backseat to ATI's 520MHz core-powered RADEON X800 XT PE. 6GT/s is nothing to be ashamed of, however.
Vertex shading is also dependant upon core speeds. With that being the case, Gainward's GLH does as well as expected.
Pixel shading performance has always been a GeForce 6800-series strongpoint. That's illustrated by the GLH taking top spot for a second time.
