Please explain Passmark

[cantholdanymore]

Most people in this forum totally disregard this benchmark, why is it so bad?
The reason I'm asking is because if you type "cpu benchmark" in google, the passmark site is at the top of the list, so a lot of semi-informed users will make their buying decisions base on this benchmark. I know I did it before finding this forum😎

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
