Performance in Semi-Synthetic Benchmarks
The results in 3DMark06 once again prove that it in fact didn’t make much sense for Gainward to launch a GTS 250 with 2048MB of video memory: the performance difference between our today’s hero and a standard solution equipped with 1024MB of memory is either absent at all or falls within the acceptable measuring error.
Futuremark 3DMark Vantage
We minimize the CPU’s influence in 3DMark Vantage by using the Extreme profile (1920x1200, 4x FSAA and anisotropic filtering). We also publish the results of the individual tests across all display resolutions to provide a full picture.
The results of 3DMark vantage are much more interesting: Gainward GTS250 2048MB managed to get far ahead of the common GeForce GTS 250 1GB in terms of general scores, but the GPU score turned out considerably smaller, although the card anyway passed 3000 points mark. Additional video memory may have come in handy during non-graphics related calculations such as PhysX physical model, for instance.
The results of individual tests do not contradict our assumptions. We only registered a slight advantage Gainward card demonstrated over the reference Nvidia solution in the first benchmark and it made about 3%. In both cases overclocking didn’t do much for the performance numbers, especially in the first test where we could see it matter only in 1280x1024 resolution.
