I am planning to buy a workstation with the fastest processor available. Currently, i have a Xeon 5160. I am confused between the two : AMD Opteron 2389 and Xeon W5580 (that's Nehalam, right?)

Any suggestions, ideas, benchmarkings available?

Thanks in advance!

Duplicate post in soni2007 thread, but have look at the Fluent benchmarks at

In general this confirms Jackill's results that Nehalem is 60-90% faster than Shanghai. It also shows the memory bottleneck seen with previous Harpertown quad-cores have been resolved. So a dual quad-core box will now give close to 8 times speedup.

The 1024 core benchmarks are at
