Better ask Joe or Mark about this one  this weekend i did compile about 50 versions of the apps so i only provided the apps and msattler and Joe did the speed testing. I only did a quick check if the apps are working 

Can someone shed some light on the diferences of the three x64 versions please? Or do these three versions correspond with what type of cpu you might have? i.e sse2, sse3 and ssse3 capable cpu's.

I have a Core 2 Duo E6700 @ 3.2ghz (on a P5B Deluxe) which has all three of these extensions, but Im not sure which extension version would run the best. lol

Any help would be appreciated.

And thanks crunch3r for the hard work,

That's what i'm telling people all day long  However... i do see a possibility to gain another 10 to max 15% in performance... but ONLY for the 64 bit app.

Anyhow, we need to get a common base (2.4V changes) for ALL apps. That' Linux,Windows,UNIX before we can start figuring out how to get some more performance...

The testbench I used was the 1.43 knabench available in the downloads 'test and benchmark tools' section.
The test WUs used are attached below.  For a short test, just run the 6 FMXXXX wus..  For a longer, more accurate test, use the MBXXXX wus, but they will take much time to run, closer to a full lenght Seti wu.
And I substiuted the 2.2b app (use the one that matches your cpu) for the reference app rather than the old 5.15 that is in the test package.
You had also asked earlier about the best wu to use for comparing apps and platforms.  That is the problem, there is no such wu.  Different AR wus crunch differently with different apps, some are faster on one than another.  So the only way you can test is by running a range of wus and see which app does better overall.
And as far as the result database, Simon has mentioned working on such a thing on the home page of this site.  Hopefully he has the time soon to continue work on that project.

No, the testbench only runs a single instance of the test app at a time on one core..  My quad is x64 and is my fastest rig, that's why I run the tests there, because I can test 32 bit and 64 bit apps.

2 msattler
Yes, this testbench uses only 1 core. My question is : is any test-bench exist to correctly test full-cores-load run times?
AFAIK conroe has common L2 cache for cores so real situation for app when it runs in parrallel on all available cores quite different from single core run.
It's interesting to compare full-load run-times on Core2 Duo/Quadro with Athlon 64 X2 version IMHO.

2 SkOrPn I don't use any graphic or screensaver so cant give any help/comments on your situation, sorry.

Many thanks

If there were a way to test the same app on 2 cores or 4 cores simultaneously, I wouldn't mind knowing if it can be done and trying it..............would it be a hard thing to modify the knabench script to do it,  or really just not worth the bother?
