Performance in Synthetic Benchmarks
Futuremark 3DMark05 build 1.2.0
The Radeon X1650 XT scores only 115 points less than the GeForce 7900 GS. That’s an excellent result considering that the AMD solution has worse technical characteristics, particularly a 128-bit memory bus, and belongs to a lower price category. Let’s discuss the results of the separate tests now.
The GeForce 7600 GT is in the lead in the “pure speed” mode thanks to its 12 TMUs, but the Radeon X1650 XT overtakes it in the 4x FSAA mode.
The Radeon X1650 XT triumphs in the second test. This is expectable considering its 8 vertex processors as opposed to the GeForce 7600 GT’s 5. The scene is rather small and the memory load is low here. This allows the AMD card to get very close to the GeForce 7900 GS.
The third test is like the first one: the Radeon X1650 XT is somewhat slower with disabled FSAA and equal to its opponent with enabled FSAA. The GeForce 7600 GT is better in high resolutions of the FSAA-less test mode, just like in the first test.
The overall outcome is correct since the Radeon is just a little slower than its opponent in two out of three tests, but has a considerable advantage in the second test. This is true for 1280x1024 resolution and should also be true for 1024x768 the benchmark defaults to.
