Most of the problems with passmark comes from the the benchmark list not assigning any weight to sample size. You cant filter out cpus that only have 1 or 2 samples. So you have to manually look at every cpu's sample size and compare only ones with a high sample count. If you dont do that you end up confused by data like this:
AMD Athlon II X2 4400e 1516
AMD Athlon 64 X2 Dual Core 5600+ 1515
Intel Celeron B815 @ 1.60GHz 1504
Intel Celeron B840 @ 1.90GHz 1504
Intel Pentium E5800 @ 3.20GHz 1469
In what world is it even possible that a X2 5600 be slower than a X2 4400e? I know it is only 1 point but still, these scores should not be even. Same goes with the two celerons. One should obviously outscore the other by around 15%. And who the heck would choose an athlon X2 4400e over a 3.2GHz Core 2? How can a 3.2GHz Core 2 with 1M cache possibly score worse than an athlon 4400. But then again wth is a 4400e?
the prefix e means energy efficient
it is the same cpu as the 4400 but consumes less power
thats the problem with passmark
also i have meet duplicate cpu with 15% diferense or more!?!?!?
the only good it has all the cpus to compare
the other think is the way the cpu score is calculated hmmmmm is something to be discused
