Anyone run R3 x64 with this processor (currently going for like $1300)?  I'm curious how much of a boost can I expect if I was to upgrade from my Q6600 2.4GHz (OC'd to 3.6GHz on P5E-VM HDMI mobo) to QX9650 or even i7 975 using the same mobo, and overclock it as much as possible.  I know the price to performance ratio will be very high and $$ wise the Q6600 will be better, but if I can expect say 600 Kn/s on avg. then it might be a bit more tempting.

I usually average about 300 Kn/s in IA mode...can someone post their numbers?  Please be specific in your answers (R3 Dynamic or Human, overclocked? ram? hash size? etc.).

I heard the Harpertown is even faster...can someone provide a link for this cpu and a recommended motherboard for it? I'm curious if it's only a bit more than a QX9650 then perhaps I should get that instead.  Though again, I'm not sure what speed boost I can expect from an overclocked Q6600 @ 3.6GHz to a harpertown (using R3 x64).  I doubt they're faster anyway...after all, the Xeon harpertown only costs between $300 & $900 (http://www.canadacomputers.com/index.php?do=ShowProdList&cmd=pl&id=CPU.606)

Thanks in advance.

QX9650 @ 3.96GHz will give you some 335 kN/s, and there's no result for i7 975, but i7 965 @ 3.8 GHz will achieve around 400 kN/s.

This is all R3 x64.

Ahh thanks.  I forgot his site has some benchmarks.

Any idea which cpu this would be exactly?

1663kN/s  Intel 5x8 Harpertown   Cluster  40 CPU

Nice speeds there.  Though I'm not sure what he means by 5x8 and cluster.  Is that 5 cpus at 8 cores each resulting in the name "cluster"? And what motherboard has 5 cpu sockets anyway? Assuming there is one, the price must be like $10,000 for the cpu and motherboard I'm guessing.

This is a result for Lukas' cluster; forgett about it, unless you have tens of thousands of € that just can't fit into you wallet. Anyhow, it is way outdated, Lukas now has a cluster of almost 60 cores (if not more?). It is a monster consisting of number of machines running Intel Xeon and i7 processors, and with special Rybka Cluster you can't buy for any amount of money.

Yes, 72 cores now. And I guess Lukas will add another machine very soon. :-)

I guess the winner of most correspondence chess games will be the one with the ultimate hardware that 99.99% of the world doesn't have :-o

I strongly disagree.  The best correspondence players are those that develop a symbiotic relationship with their chess engines.  When the tactical wizardry of the engine is combined with human sagacity, strategic planning and creativity the end result is a chess player that is capable of playing chess at a level that is much stronger than the sum of its parts.  No amount of hardware can compensate for the human element.  There will never be an engine-only CC world champion.

"you can't buy for any amount of money"

Wouldn't be sure about that ;) But it would be quite a bit :)

I stand corrected. :-)
