AMD64 vs Dual MP's

Hey guys, I'm working on the RC5-72 effort over at distributed.net and I was wondering which setup would be faster. For the AMD64 system I was thinking a 3400+, a Gigabyte board using the Via chipset, at least 1.5GB of memory. For the MP system I was thinking (2) 2800+ MP's, Tyan's Tiger MPX, and at least 2GB of memory.

One of the problems I'm having is I can't seem to find a RC5-72 keyrate for the AMD Athlon64 3400+, I have found the keyrate for the Dual 2800+ MP's, it is 13,850,114 keys/s. The only entry I see at the speed site, http://www.distributed.net/speed/, for a AMD64 chip is for a 1600+, which I didn't even think they made, and it said the speed was 5,771,251. There was also a Opteron 2200+ that's speed was 8,199,173. I would get a dual Opteron system but they are way to expensive.

So any help would be appreciated, especially if someone has a 3400+ CPU and could benchmark it for me, that'd be even greater. You can get the zip file with the program at http://www1.distributed.net///download/clients.php.
 
Hi lelliott731,
You might be better off asking distributed.net questions in a forum with more distributed.net experience since we almost exclusively talk about medical and science DC projects. I used to do RC5-64 back in the day, but have since moved on to medical research projects so I don't have any idea if my memories apply to the new projects. Have you thought about looking for cures to diseases instead of cracking encryption keys? A lot of us used to do SETI and d.net but found Folding or UD to be a lot more satisfying. If you do decide to join, Folding would love that MP setup you're proposing! :)
 
That is a really good post lelliot731, kudos on lots of info... if I had a 3400+ I'd bench it for you... nobody (that I know of) is running one of those around here yet, but maybe somebody has a 3200+ you could extrapolate from?
Look at the the Medical DC stuff... It sure does some useful stuff.
cheers, and good luck... sharp
 
Fresh from the oven. ;)

So the dual MP's whip the AMD64 3400's tail. They pump out 13,850,114 keys/s. Thanks for the info CIWS!

Sounds like it, I'd have to run it on my Dual 2600+, but I suspect each of those CPUs does 6-7 mill keys, which combined will still stomp the single CPU setup.
 
Na dude, I ran RC5 and a few other dist.net clients years ago. Everything is now working on medical oriented stuff. Folding,UD,FAD, etc It took 200 thousand+ people almost 5 years to crack -64 and everthing is already at least 128bit encryption. So I'm not too worried about a brute force attack ;)

CIWS you want to join my RC5-72 team:)?

I don't think he does, but how about you join our folding team?
