Futuremark 3DMark06

Both versions of GeForce 8800 GTS behave just like in the previous test, but 3DMark06 uses more complex graphics. Combined with 4x FSAA in some tests, this should produce a different picture of performance. Let’s check it out.

The separate groups of tests bring us expectable results. The SM3.0/HDR group makes use of a number of more complex shaders and the advantage of the GeForce 8800 GTX is more definitely outlined than in the SM2.0 tests. The AMD Radeon X1950 XTX looks good when the application uses Shader Model 3.0 and HDR whereas the GeForce 7950 GX2 looks better in the SM2.0 tests.

When we turn on FSAA, the GeForce 8800 GTS 320MB falls behind the GeForce 8800 GTS 640MB at 1600x1200 and cannot pass the tests altogether at 1920x1200 due to the lack of memory. The speed of the 320MB version is almost two times lower in both SM2.0 tests although the two are quite different in terms of graphics scene design.

The amount of graphics memory affects the card’s performance even at 1280x1024 in the first SM3.0/HDR test. The junior GeForce 8800 GTS is about 33% slower than the senior one then. And this gap grows up to 50% at 1600x1200. The second test, with a less complex and smaller scene, does not need too much of graphics memory and the gap between the two cards is 5% and 20% at 1280x1024 and 1600x1200, respectively.
