Performance: Central Processors
Now that we’ve learned how the CPU performance test works in 3DMark06, it’s time to do some practical testing. First, here are the overall CPU performance scores that 3DMark06 produces:
The first thing we should mention is that the CPU test from 3DMark06 is really well optimized for dual-core processors. The difference between the single- and dual-core CPUs strikes your eyes immediately.
Among dual-core processors, the models from Intel’s Pentium D and AMD’s Athlon 64 X2 series keep on roughly the same level. Although AMD’s processors are a little ahead of Intel’s processors of the same price, the gap is a negligible 5%.
Intel’s Pentium 4 is superior among single-core processors, most probably due to Hyper-Threading technology.
If you are interested in details, take a look at the results of both the subtests the overall CPU rating is calculated in 3DMark06.
Although these tests vary in their use of physical modeling and AI algorithms, the relative results are almost the same.
And lastly let’s see how strongly the CPU performance affects the overall score in 3DMark06.
So, the CPU does affect the overall score, but not too much. The weight coefficients in the overall score calculation formula are selected such that it is the graphics subsystem performance that becomes the basis for a 3DMark06 score.
