Performance in Synthetic Benchmarks
Futuremark 3DMark05 build 1.2.0
By default, 3DMark05 uses 1024x768 resolution without full-screen antialiasing. The Radeon X1950 XTX cannot show its best under such conditions because its fast memory is of little use then.
The first test depends heavily on the speed of processing textures and, accordingly, on the graphics memory bandwidth. Since we also enable full-screen antialiasing in our tests, the Radeon X1950 XTX has something to show its muscle on and it does so, leaving the Radeon X1900 XTX from 15% to 20% behind.
The second test renders a smaller scene, and the Radeon X1950 XTX only enjoys a 10% performance boost. This is enough to make it the leader among single-chip cards, though.
The new card from ATI is about 10% ahead of the Radeon X1900 XTX across all the resolutions in the third test, too. It doesn’t reach the level of the GeForce 7950 GX2, but it’s incorrect to compare these two cards directly. Nvidia’s solution is a dual-chip device and is in fact a SLI tandem, although occupies one PCI Express x16 slot.
So, the new Radeon X1950 XTX really has a bigger potential than the Radeon X1900 XTX but only reveals it in high resolutions and/or with enabled full-screen antialiasing.
