Now let’s have a look at the influence faster bus of Athlon XP Barton processor may have on the rendering tasks.

The results are not at all surprising. The CPU computing capacity is of No.1 importance during rendering. That is why CPUs working at higher clock rates outperform processors with lower clock frequency no matter how fast their bus is. As for the outrageously high results shown by Pentium 4 here, Intel owes them to Hyper-Threading technology, which sometimes affects the performance in multi-threading tasks quite significantly.

Absolutely the same situation is valid for rendering speed in Lightwave 7.5.

And again nothing new. No comments needed.

How well will the overclocked Barton with 400MHz bus perform in professional OpenGL applications? The answer to this question will follow from the results of SPECviewperf 7.1.

Athlon XP with 400MHz bus appeared very fast here. The only test where Pentium 4 managed to defeat the hypothetical Athlon XP 3200+ was 3dsmax-02. In all other tests the laurels were indisputably won by AMD processors. We would like to specifically stress the results of drv-09 and proe-02 tests, where faster Athlon XP bus ensures a tremendous effect.
