UPC the truth is that all of these benchmarks are pretty obscure. All of them could probably use tuning as well.


Well, we're just talking about compilation switches here. That
they didn't fix the Xeon compile is an indication that they
didn't have to. Though it's hard to figure out what happened
given the incompetence of the person doing the benchmarks.

They were originally done on an AMD ONLY REVIEW

Please provide a link to the AMD-only review on the chess
benchmark.


But the fact that intel was very competitive on super pi and other athlon favorable benchmarks(doesn't AMD win by a much larger margin in my sql under a 32 bit OS) indicates that 64 bit performance is just fine


Did they run any > 4GB memory benchmarks?


And it indicates that running 64 bit programs is a pain and it isnt for free:)

Running 32-bit programs is a pain if you don't know what you're doing.


I'm sure the amd fan boys like you are tuning the code to prove their platform isn't inferior but other than a few geeks who cares?


I'm sure that Anandtech cares about its reputation.

Why everyone should care is to provide accountability. If
Anandtech said that 1+1 = 3 on an Intel processor, I'm sure
the Intel guys would have a problem with that.

There is one person who frequents this board (and I'll keep his identity private to satisfy the TOS) who used to argue that the only reliable CPU benchmark was the calculation of Pi, since it wouldn't make use of a processor's cache or memory subsystems. Needless to say, the silence is now deafening.

Hey sorry it works out that way, but that is in fact the case.

As for super_pi, they had no access to any source code, or build configuration, just a random binary, so it is not a reasonable test. It probably isn't even 64-bit. And who knows what processor it was optimized for?
