Futuremark 3DMark06 build 1.0.2
The GeForce 7950 GT scores more points in 3DMark06 than the Radeon X1950 Pro but 439 points less than the Radeon X1900 XT.
The difference is smaller in the SM2.0 tests that are free from advanced shaders, but bigger in the SM3.0/HDR tests where the progressive graphics architecture from ATI works under favorable conditions. The Radeon X1900 XT is just a little faster than the GeForce 7950 GT in the first group, but easily overtakes the GeForce 7900 GTX in the second group of tests.
The results of the separate SM2.0 tests look logical to us. The first test is a burden for the relatively weak TMU and ROP subsystems of the Radeon X1950 Pro. Well, even the Radeon X1900 XT, with much better specs, is a mere 0.2fps ahead of the GeForce 7950 GT.
The second test provides an opportunity for ATIís cards to show their muscle on processing the complex geometry when rendering the abundant vegetation and to use the advanced lighting and shadows processing capabilities of the RV570 and R580 chips.
The GeForce 7950 GT looks generally preferable to the Radeon X1950 Pro but ATIís solution belongs to a lower price category whereas the Radeon X1900 XTX, at least its version with 512MB of graphics memory, leaves no chance to the GeForce 7950 GT.
