Different CPU Mark values with same processor

[David (PassMark)]

Yes, RAM speed and setup (e.g. dual channel) can effect CPU performance. As can background software, power schemes, cooling and other factors.

Hello,

I have done some running of PerformanceTests in two PCs with the same processor and similar components. In one PC I always obtain a better result compared with the other one. If the processor is same in two PCs, why do I get a different result in CPU Mark? Does the rest of components or software configuration influences in the results?

Thanks.
