Error in the Intel Core i7-2720QM @ 2.20GHz bench?

[gfxman]

I'm going to buy a new mac book pro 15, and, using this page as reference:

http://www.intel.com/products/processor/corei7/mobile/index.htm

it should have the

i7-2635QM - 2.00 ghz /
i7-2720QM - 2.20 ghz /
i7-2820QM - 2.30 ghz /


The pass mark cpu says ( http://www.cpubenchmark.net/high_end_cpus.html )

Intel Core i7-2720QM @ 2.20GHz > scores 7,155

the strage thing is that the superior cpu model, scores far less

Intel Core i7-2820QM @ 2.30GHz > scores 4,88

How is that possibile ? Thank for any reply.

From time to time, it is necessary for us to manually clean up the charts. In this case, there were a few submissions for the Core i7 2820QM that were using older builds of PerformanceTest that did not fully support Sandy Bridge. This skewed the average toward the lower side for this CPU.

I see, you update the charts to fix the values, thank you!
