45nm Phenom Overclocked, Super Pied

[hokiealumnus]

Hi, hokiealumnus Well I'm quite bussy with folding and I can tell you that the multi core client for folding, isn't doing much intercore communication.
It's not like the ps3 client that does do a litle bit of work on each spu.
the folding multicoreclient behaves like a client that can work on a grid of computers, so it doens't need the big intercore bandwith (it's not like the intel intercore communication is as slow as ethernet ) That's why folding smp needs the MPI service for multicore! So phenom will only outperform Core 2 if folding would implement somthing like the ps3 core, but that doens't make much sens for a normal x86 cpu.

This makes complete sense, thanks for that.

I should point out that the F@H results I was quoting were from Windows XP 32-bit. I have been having issues with Ubuntu (64-bit) and this rig, but when it actually folds right, it gets significantly higher ppd. It's been a while since I tried (trying again and typing from Ubuntu now), but IIRC project 1753 got ~2,200ppd, which beats the C2D by just over 300 on that project. I guess it just needs the right application to take advantage.

I guess the conclusion one can draw from this is that the C2D/C2Q platform isn't necessarily better (when ignoring the overclock potential of course), it's just different. Were more applications tailored specifically to AMD's architecture and not to Intel, we may see the reverse happen and Phenom beat Core2.

So, this has helped me learn some about why my Phenom isn't as bad as I thought. Thanks for everyone's input. I feel slightly better now.

Now, let's all continue to cheer on and support AMD. They'll get over the hill and beat Intel again; they have before. 3.4GHz (even if at insane Vcore for a 45nm chip) is a definite step in the right direction. Go AMD!
