Performance in Semi-Synthetic Benchmarks

Futuremark 3DMark06

 

The GeForce GTX 275 is first in 3DMark06 when overclocked. Without overclocking the card scores as many points as the GeForce GTX 285 and loses to the Radeon HD 4890.

At the default GPU and memory frequencies the GeForce GTX 285 has a very small advantage in the individual groups of tests. Perhaps its advantage is more conspicuous in the SM3.0/HDR group. Overclocking has a different effect: there is almost no performance growth in the SM2.0 tests but the SM.30/HDR tests are won by the overclocked GeForce GTX 275 with a score of over 8000 points.

Futuremark 3DMark Vantage

We minimize the CPU’s influence 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 difference is far more substantial in 3DMark Vantage as this benchmark defaults to the resolution of 1920x1200 with 4x FSAA and uses all of the resources a modern graphics processor can offer. Anyway, the overclocked GeForce GTX 275 can catch up with and even outperform the GeForce GTX 285, scoring over 6,000 points.

The individual tests agree with what we have seen above but the difference between the two mentioned cards from Nvidia is somewhat more conspicuous in the second test and the overclocking is more beneficial. This is quite logical considering that the second test puts a higher load on the memory subsystem and RBEs.
