It seems like AMD might have a leg up on Intel on this one... and apparently the system integrator who did this also sells Itanium and Xeon systems.... and says that he gets significantly better performance from Opterons
Of course you have to compile the binaries on a Xeon machine... thats the catch
Read the article[The Inquirer]
Re: Manufacturers use Intel compilers to make AMD Opterons fly
sweet, I missed this article. Very interesting.
To be honest, though, I'd be more interested in seeing an Opteron vs. Itanium performance comparison rather than Opteron vs. Xeon. I mean, I'd really hope that Opteron can beat Xeon hands-down (which it does :-)).
