Performance in Synthetic Benchmarks
Futuremark 3DMark05 build 1.2.0
The relatively small advantage in terms of GPU frequency helps the PowerColor X1950 Pro Extreme reach the 10,000 points mark, scoring 404 points more than the standard Radeon X1950 Pro does. This is expectable since 3DMark05 defaults to 1024x768 resolution without FSAA, and the memory subsystem performance isn’t very important under such conditions.
We can see the same trend in every test: the PowerColor card has the biggest advantage over the reference card in 1280x1024. In the higher resolutions it is limited by the memory frequency. The GeForce 7900 GS is always slower than the PowerColor, but differently in each test. The lag is the biggest in the second test that requires high speed of execution of shaders, both vertex and pixel, but doesn’t need a high fill rate.
