FAH - x2-3800 v C2D 6300 = AMD Wins?

[FatRakoon]

Got a funny one here.

Im playign about with a few of my PCs setups, and I have run a few tests on them with FAH. ( Bloody takes ages, but why not )

Anyway, im having a look at my stats with FAHMON

Now, I have seen somethign very interesting..

Ok, what I have been messing about with the last few days is simply getting them to run the same projects and simply comparing them

Funny one this, but I have found, that my conroe is the slowest CPU for folding according to FAHMON anyway.

What I have is this...These are a couple of the current projects FWIW

Project : 1809

Opteron 144
= Avg. Time / Frame : 10mn 14s - 215.30 ppd
Conroe ( Core 1 )
= Avg. Time / Frame : 17mn 21s - 126.99 ppd

Project : 2125

X2-3800 ( Core1 )
= Avg. Time / Frame : 44mn 11s - 127.76 ppd
Conroe ( Core 2 )
= Avg. Time / Frame : 45mn 07s - 125.12 ppd

Can you see what I mean?

The opteron 144 is doing the EXACT same project as CORE 1 on the Conroe, and one of the cores from the 3800 are running the very same project as CORE 2 on *** conroe.

On both Projects, the AMD is proving the quicker, the x2-3800 by a very small fraction, but the Opteron is almost double the speed of the conroe!!!

These are 2 projects I know, but even the last time, I ran the same project on these 3 systems, with both cores on the conroe and the x2-3800 so, 5 different cores running the same project and in that project, which IIRC was number 1809 ( Amber ) the opteron had also completed that project a good few hours before either the 3800 or the C2D had.

Does this then prove that for folding, an Opteron is a better choice than a conroe? Also that the x2-3800 is a tiny tiny bit quicker than the conroe???

Surely not?

That cannot be right can it?

Anyone care to verify these results? Perhaps if oyu have both an AMD and a Conroe to run the very same project on both and tell me which CPU completed their project first?

Thanks for that reply.

Project 2125 is Gromacs, and the conroe is 1 minute slower over 45 minutes.

Project 1809 in an Amber and the Opteron is a full 7 minutes quicker than the Conroe.

As you say however, its Mhz v Mhz and different projects are better for their CPUs then...

That would indeed bring things closer perhaps.

The only double gromacs Im runnign right now is the P4 2.6 which is only switched on for a few minutes here and there, and dont have any tinkers

The Conroe is currently at stock, so I will slow the Opteron down then, and see if I cant grab tiny/quick projects for all 4 of the different types and re-give it another go perhaps?

Sorry, I didnt get your Reply Lay-z-boy till I posted this.

I suppose it could be just a chance then, that perhaps I managed to get projects that happen to be much better on AMD than on Intel?

If thats the cae then, then surely if one can be selective n what projects you run, you can in theory, use only very efficient projects on a poor spec AMD and actually get much better high scores than someone with a top-end intel then?

...In theory at least!

 

[FatRakoon]

Yes, Im not selective on what comes down... If I catch it early, I will stop it and simply copy the data over to another PC rather than anything else... I just wait for FAH to give me a new project on the cores otherwise.

How can I select specific projects?

I should run a couple of older ones and a couple of newer ones then.

Old and new on each core perhaps?
