I was wondering if there any benchmarks out there comparing Itanium 2 to opteron. Seems like with Itanium 2 at 1.5 ghz only opteron should be the top dog in 64 bits now. Really haven't heard about how amd is doing with sales vs intel in the 64 bit server arena though. Just wondeirng whats going on there.
lol I was asking for benechmarks comparing those 2 cpus, I wasn't giving any evidence about it. And it meants it just seems like opteron might be better because its got .5 ghz more than itanium. Anyhow like I said before I can't find any benechmarks comparing 64 bits cpus anywhere.
Considering the similarities between the K8 and K7, I'd say that plenty of the optimizations and tweaks that have gone into x86 compilers over at least the past 3 or so years (since the release of the K7 at least) will benefit the K8. Add on top of that how trivial it is to adjust a compiler to take advantage of the extra registers and I don't think IA-64 has any advantages in terms of compilers than the K8.
If anything, IA-64 is at a disadvantage because the K8 is a much more traditional OoOE core with high-frequencies and a 3-way superscalar design. Compilers have been designed and made with such architectures in mind for the past 10+ years.
Compiling methods and principles for an in-order VLIW architecture just recently came into focus because of Intel's push of IA-64.

However, the recorded benches speak for themselves. The fact is that the Opteron was running on a 32 bit OS most likely executing 32 bit code. Whether or not running in 64 bit code actually improves the Opteron, the Itanium is currently running native 64 bit code.
I you can remember well that was a co production project made on P7 at the 1 place and legitation have appear after that intel sperate from co-project that far from be anything relate to Itanium wich have start in 89 lab at HP
