Vertex Shader Performance

Due to very high clock frequency, RADEON X1300 PRO is seriously ahead of GeForce 6600 and RADEON X700, which is far from being a logical outcome, I should say.

The same test from the 3DMark03 benchmarking suite reveals a much more realistic result. 2 vertex processors of the RADEON X1300 PRO do not let it catch up with the GeForce 6600, and especially RADEON X700, which boasts 6 fully-fledged vertex processors, as you know.

It is interesting that in case of a simple vertex shader 2.0, RADEON X1300 PRO is again victorious and undefeated. It probably the fast rasterization unit that determines this success, due to high working frequency of the solution.

High core frequency and 128-bit vector ALUs allow RADEON X1300 PRO to show pretty decent performance during complex vertex shaders processing. Nevertheless, it is not enough to catch up with the RADEON X700 with its 6 vertex processors.

The same is true for the geometric Xbitmark test, where the newcomer yields only to RADEON X700.
