Vertex Shader Performance

Both, GeForce 6800 as well as RADEON X1600 XT feature 5 vertex processors onboard. Although the newcomer from ATI has them working at a significantly higher frequency, which determines the excellent results in this test.

The same picture can be seen in the corresponding 3DMark03 test.

Even higher performance advantage over the previous generation solutions can be observed in Simple Vertex Shader test from 3DMark05 test suite. In this case RADEON X1600 XT proves more than twice as fast as GeForce 6800.

This advantage is slightly smaller in Complex Vertex Shader test, although RADEON X1600 XT remains an indisputable leader.

With no light sources involved, the performance of GeForce 6800 and RADEON X1600 XT is about the same. The latter gets ahead of the competitor with 4 light sources in the scene. And the best result is achieved when there are 8 light sources activated. This is another piece of evidence proving how efficient ATI’s new vertex processors are.
