Our first benchmark to start it off would be Futuremark’s 3DMark06.
In the benchmark, the SM3.0 and SM2.0 aspects of rendering are tested separately
and this would help to differentiate the capabilities of the different cores.
As shown in the results, the new core does in fact have better
rendering capabilities when it comes to SM3.0/HDR rendering as the scores do
show a significant improvement in the SM3.0 score: a whooping 50%
gain. Apart from that, however, SM2.0 rendering only improves by a slight margin.
Next up, also from Futuremark, 3DMark05 is widely used for
it’s accurate results on guaging performance on different GPUs. This synthetic
benchmark is similar to 3DMark06 with less of the fancy stuff.
With less HDR/SM3.0 rendering, the 7800GS doesn’t really pull
as big a margin as it does in 3D Mark 06. Still, the 7800 GS offers a pretty
decent 15% gain over the 6800 GT.
