In recent tests Open64 is better than ICC at producing code that executes on the Pentium Dual Core T2370

In fact, its not just better... its significantly better.

Stop talking out your ass.

So what is the best benchmark (however that is defined)?

Phoronix test suite

The venerable UnixBench BYTE magazine lineage, updated by Yahoo.

Geekbench

If you want to know which filesystem would perform the best, you might try just benchmarking them all with the Phoronix Test Suite. (I haven't tried it myself, but I read Phoronix' news, and there's all kind of pretty graphs.)

Phoronix Test Suite ( http://www.phoronix-test-suite.com/ ) supports Win7 now. It also allows comparison against OSX and Linux ( http://www.phoronix.com/scan.php?page=article&item=linux_windows_part3&num=1 ).

It's Free, it's Open Source and has a bucketload of tests already. You can combine result sets and you can even get the results uploaded for comparison at http://global.phoronix-test-suite.com/

Creating your own tests is nice and easy too.

(Full disclosure - I am one of the project members).

It doesn't run on Windows but Phoronix Test Suite would give you a good baseline for the hardware.

So what's stopping you? :-) They give instructions on how to do this here. The only thing it probably won't do well is bootup testing, but then you probably want something like Bootchart for that.

``Note: I'm not defending the Phoronix guys. As a previous poster pointed out, they are inherently bad at explaining the why things are slower and sometimes they are flat out wrong''

In that case, the best they can do is to stop talking about it and just stick to what they know. Knowing just what is faster and what is slower is useful by itself. It can be used as a starting point for investigating what exactly caused the speed-ups and slowdowns. If the Phoronix folks can't or don't want to do this investigation themselves, it's perfectly fine to leave it up to other people.

If you're really so curious you can oprofile and find out yourself.

I'd say, let's use http://phoronix-test-suite.com/ btw, sorry for the GenuineAMD typo ;D As it is already tagged - I meant AuthenticAMD

The Phoronix Test Suite.

It's Linux only, but a CPU that performs better on Linux will perform better on Windows.
