Memory performance - Stream

Website: University of Virginia

Stream is a synthetic memory bandwidth benchmark developed by John McCalpin at the University of Virginia.

It comprises four individual tests, each of which represents a typical long vector operation, a typical workload in server and HPC applications.

Unfortunately, the Windows version of Stream is hardcoded to support 1, 2, 4, 8, 16 or 32 threads, not the 24 threads native in both of the test systems in this review. For this reason we ran Stream with the 16 thread profile enabled.

I'm hoping this line isn't a misprint
6128 2GHz 8 80W 1,333, 1066, 800 $266
Though the motherboards are FAR from economical (in regards to a specialty case requirement, and high set up costs), 8 physical cores at 2GHz a piece is a rather INSANE value for $266.

No, it's not a misprint, but don't forget that $266 is the list price, so what you end up paying (depending on where you buy it) won't be exactly the same as this. It's a great price even so :)

looks like folding has a new king... might be time to save for a amd 6174setup!

you got the Xeon table wrong - the logical cores column
