Synthetic Benchmarks: Pixel Shader Performance

This utility can also tell us quite a bit about the performance of this or that graphics adapter during shader processing:

During per-pixel lighting processing DeltaChrome appears in between GeForce FX 5700 Ultra and RADEON 9600 XT. With simple pixel shaders 1.1 DeltaChrome showed its best performance. It is not so successful with shaders version 2.0, although even in this case its performance is close to that of RADEON 9600 PRO. Not bad for S3 Company, which hasn’t been in this market for three years!

With disabled Z writes nothing actually changes.

And as soon as we disable color writes the situation no longer looks so rosy: S3 DeltaChrome is a complete loser in all tests. The new VPU runs the worst during per-pixel lighting processing. Maybe it is the low working frequencies that cause this disaster, or again, the raw drivers.

In order to represent the results in a more convenient way, let us take a look at Pixel Shader performance in 3DMark 2001SE and 3DMark03 benchmark suites:

In case of pixel shaders 1.1, S3 DeltaChrome S8 can hardly boast any remarkable achievements, although it manages to outperform GeForce FX 5600 Ultra in two modes out of three.
