Performance in Gaming Benchmarks: Synthetic Tests

Futuremark 3DMark05 build 1.2.0

Although GeForce 7950 GX2 uses a new driver that belongs to the ForceWare 90 series, its result is only 147 points ahead of the GeForce 7900 GT SLI. If we compare these two solutions from the technical specifications standpoint, the result like that will be quite logical, because GeForce 7950 GX2 has faster GPU than GeForce 7900 GT SLI, but its memory is slower.

If we compare our hero against Radeon X1900 XTX, the new Nvidia solution will be 1258 points ahead, which is about 10% (since the overall performance rate lies around 12,000). Not very impressive I should say, since the baby features two graphics processors onboard, but it is a victory anyway.

In the regular eye candy mode the newcomer outperforms GeForce 7900 GT SLI by only 5% in 1280x1024. In 1600x1200 this advantage doubles: 10%.

The advantage of GeForce 7950 GX2 over GeForce 7900 GT SLI starts growing only when we enabled SLI AA 8x and reaches 20%. Although we are talking about the today’s highest-performance graphics systems, the best performance they can provide is 40fps on average. In other words, it is absolutely insufficient for the next-generation games with enabled extreme anti-aliasing modes.

In SLI AA 16x mode GeForce 7950 GX2 retains its intermediate position between GeForce 7900 GTX SLI and GeForce 7900 GT SLI.
