On second read this was confusing. The best STREAM results from using the Intel compiler on Linux. The ones I've been doing and that Scott has been running are using regular gcc instead. So when the new AMD system is clearing 75MB/s in the little test set I'm trying to get automated, that's actually a conservative figure, given that a compiler swap is almost guaranteed to boost results a bit too.
