Yes, but I didn't say that I wanted to buy 168 Xeon CPUs in several racks of blades and equal the amount of points that he's capable of producing. If I sold every folding rig that I have right now, new and old, and every spare card that I have which hasn't made it's way into a rig yet, I'd have more than what it would take to build a fully loaded SR2 system. And it alone could produce more points running Bigadv SMP units as well as a couple of GPUs than my current setup is capable of...
For what its worth.... I had an old core2 system, a q6600 getting pretty mince points and my gtx460 was getting 15,000 per day. I thought that was good until I got my i5 2500k, only draws 150W at the plug when going full tilt and gets 22,000 PPD on its own. i7 2600k should be a similar power draw and hammer out a heck of a lot of points with bigadv, anyone know how many roughly? Some of these new CPU setups make GPU folding a bit of a waste imo.
Hi James_ Please put us out our misery and tell us what the specs of the kit is?? Im gonna start buy guessing its a rendering farm set-up for a image/design company, the speed of the WU's coming out of that/those rigs is immense. If im right, what GPU's are they running....Tesla? Anyhoo please let us know! Cheers
I can tell you exactly what a 2600K @ 4.5 Gig delivers : - 50K PPD bigadv on Linux. Power from the wall 165 Watts. It probably beats anything on the market for folding efficiency either in £/PPD or PPD/watt unless anyone cares to bring forth a different candidate Sorry, off topic really
Thats nice mate, especially as you can squeak a higher overclock usually out of the 2600K. You would need about 5 460 GTXs presumably for 50K PPD, which is £500. You can build a full 2600K rig for that, maybe?
5 X 460 GTX = a lot > than 160Watts. The cost of 5 GTX 460s + support hardware = a lot > than a 2600K rig. I agree a 2600K is capable of a lot more than 4.5Gig but where I run mine seems a sweet spot. I use an Asus P8-P67 (B3 stepping) with all volts on auto resulting in a core of 1.3V - the simplest OC I've ever done.
1.3V is pretty insane, my 920 runs 3.8GHz with HT at 1.2V! And indeed, 5 460s would draw shitloads more than 160W, you couldn't fit 5 in one rig and thus would need two with expensive mobos and PSUs. The other simple fact about GPU folding is that expensive GPUs give no return at all - my GPU was £400 and barely does better than GPUs half the price in folding while guzzling the watts.
What GPU is in that system? I'm toying with the idea of building a newer z68 system later this year just using onboard graphics, so even lower wattage. Three of your systems would also probably out ppd an sr-2 rig and for less power and much less £££ to build.
Yeah, GPU folding has definitely lost all that once made it great. The increased efficiency and decreased cost of new multi core CPUs along with the better SMP client has shown GPU folding up a bit, but remember that less than a year ago a rig full of high end GPUs was still the best way to achieve maximum points from a single box. Times and trends change though
Well, you're taking an extreme example, but I do agree, gpu folding has lost a lot of it's appeal. Used to be cpu folding had a bigger initial outlay, but with lower power consumption etc, so better int he long run, but now the initial outlay is no bigger alot of the time.
Apart from the hassle and drop in PPD until you got set up, wouldn't that save a fortune in power and have a better PPW? folding should be measured in WU's rather than points =p lol
As I peer into my crystal ball, I see... no, it can't be... but, yes GPU3 -bigadv WUs, requires GTX580 or above.
