The problem with PassMark is that it is pretty inaccurate. Best to wait for real application benchmarks before getting your hopes up.
What's makes you say it's inaccurate?
Based on my understanding and interaction with the PassMark community, the developers go to great lengths to ensure their benchmarks are as accurate as possible. And like other CPU benchmarks, they take into account various factors for calculating the cpu score, including: -
* integer maths;
* floating point math (fpu);
* prime numbers;
* multimedia instructions;
* string sorting;
* 32/64 bit performance;
In fact, I would say it's far more accurate than crod like SysMark by BapCo - over which various processor manufacturers (via, amd, nvidia) have revolted against.
