Yep! The Test-Select score should be 215, not 289!!!

He couldn't even copy the 64bit result from his July 19 benchmarks correctly (he pulled the 32bit one by accident):

This whole article is shoddy. Already, folks at Ace's are noting many of the results were not compiled for AMD64, and are not reproducible.

Anand's test is a joke

Nah, if you objectively test, then any A64 > 2Ghz will completely eat alive that P4 3.6ghz of course.

But you definitely need good 64 bits compiles from the software and not flawed tests which measure videocard speed nor tests with intel c++ executables in 32 bits at both machines (or even 64 bits at the P4 and 32 bits at the A64).

You must compare of course objectively and they didn't do this.

Good examples is that i can compile tscp at a 2.2Ghz opteron while someone else is gaming at the other cpu, so effectively i've got less than 1 cpu and i get a score of 311k nps for a program that runs within L1 cache and they managed to get 155k nps at an A64 with it.

That's really pathetic. I just did a simple compile gcc -O3 -mcpu=k8

Now please watch the stupid other software they picked. gzip is in specint and not 64 bits either.

It's a hard fact that at 64 bits the P4 will be more dissappointing compared to opteron than when you compare 32 bits.

The small L1 caches of the P4 will really not survive 64 bits code + data. It will be outdated before it is released therefore this P4 Xeon 3.6Ghz.
