Thanks for Your answers, it helps me very much.
If it was 940 i7 that I am really impressed by these speedup results!!

Found this from SGI, look at page 2

AMD Opteron 2389 vs. Intel Xeon W5580
 

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!

Nehalem benchmarks on up to 1024 cores
 

Duplicate post in soni2007 thread, but have look at the Fluent benchmarks at
http://www.fluent.com/software/fluent/fl6bench/new.htm

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
