I came across this website: http://www.caselab.okstate.edu/resea...benchmark.html. And found they have a benchmark for parallel CFD performance. The data base of tested cpu's is not very large at the moment. But they offer you the possibility of running the benchmark yourself, and submit the results.

A limitation of the benchmark is that your pc must be x86 compatible.

Under downloads you can find a XML file with the data of the tested cpu's. There are also two other files which contains the data to run the benchmark yourself. It is quite easy to run the benchmark and it is fast.

I think it is nice to have a good overview of the performance of different cpu's in a parallel set up, so i would like to ask you to run this benchmark on your machine and submit your results.

Thank you in advance! A lot of people will appreciate your effort.
