Are you sure? Wouldn't 4x interlagos 16 core CPU's have more like 32 cores (in regards to f@h) because of the shared FPU?
 
No, I'm not sure and in truth, I'm not up to speed on AMD server processors at all. If Interlagos is like BD, and M-C has one FPU per core, then I know for sure interlagos ppd would be lower than M-C ppd.

Come to think about it, I think Macaholic posted interlagos numbers that were quite a bit lower than those M-C numbers.

Macs numbers are on a 4P Opteron 6124HE (M-C) @ 1.8 GHz.

Obviously with AMD pricing it's time to become familiar.

there is some stats on 4x16 cores 2.0ghz of interlagos

p6901 : 3:52 tpf
~647K ppd

*of course with p6903/4 would be much higher

[09:15:07] Completed 0 out of 250000 steps (0%)
[09:18:59] Completed 2500 out of 250000 steps (1%)
[09:22:42] Completed 5000 out of 250000 steps (2%)
[09:26:16] Completed 7500 out of 250000 steps (3%)
[09:30:08] Completed 10000 out of 250000 steps (4%)
[09:34:06] Completed 12500 out of 250000 steps (5%)



Interlagos would be the choice if stats above legit.
 
Very impressive indeed.
What motherboard is that running on?

HOLY SCHNIKIES. That's some ridiculous PPD. 2GHz Interlagos are about $523 each and 4p boards are about $800. Throw in a good power supply and you are at about $3k for a system. This is equivalent to 6 2600k rigs price-wise but 13 times the ppd.

the PPD does make sense, given [email protected] can achieve 670K ppd with p6903.

you forgot about the 16x1GB RAM :D
 
Low-end 4P G34 6124HE (32-cores) will complete p6903 every 2 days for approximately 200PPD. FYI, The Egg now has Interlagos. Get 'em while they are hot. Use a Xigmatek Elysium case if you want. ;)

mecaholic, dumb question for you but why is your ram configured specifically in those slots like that and what is the max ram that board can hold? That thing just looks sexy, how is heat output and do they overclock?

Edit: after looking harder at the pic it looks like all the ram slots are being used, I thought you were only using the red sticks at first glance lol.
 
I know they are not out yet, but a single 8 core SB-E Xeon should do the new big adv correct? Should be able to throw those in a X79 board and overclock it too!
 
yes those Xeon E5-26xx with 8c/16t should able to qualify but PRICEY :) 2x the price of 16-core of interlagos.
Cost you an arm and leg to throw those puppies in desktop board to OC, unless you can get ES version. At least from f@h perspective, xeons only cost effective if running 2P to take advantage the 4x bonus factor.

Might be two times the price, but with interlagos you can not overclock at all. I would expect the cheapest E5-2650 to do better than dual interlagos. The turbo multi should be at least 22 (I can't seem to find it listed anywhere). I have not played around with the bclock multi much yet but my board has 125, 166, and 250 settings. If you can use the 250 bclock for the CPU, you will easily hit the max frequency possible.
 
i used to fold with 2 SR2s , X5650s and L5640s. If i knew what i know now, i would pick AMD48 route. (costs the same but 2 SR2s twice the e-bill, PPD on amd48 much higher)
Yes, XEON oc better but we are talking physical vs logical cores here. F@H love physical cores. That was the story between Magny-cours and Westmere

I dont think the story much difference with Interlagos vs SB-E

i dont think a single E5-2650@4ghz+ can out fold 2x16 interlagos.

How does interlagos have better PPD/watt than SB-E? Last time I checked bulldozer was a hot slow chip that got terrible PPD. Isn't interlagos just the server version of bulldozer? I'm not 100% up to date on this stuff either so I would love an explanation.

I can see a 4p amd system destroying a single socket xeon with expo, but not a 2p amd system. At the cost of a 4p system you could end up with a SR-3 when it comes out and dual SB-E xeons.

What we really need is an AMD 4p board that supports some kind of overclocking hehe.
 
THe interlagos chips run at much lower frequency and voltage than the bulldozer, hence better ppd/watt.
 
Much better said, since interlagos is a bulldozer. What I meant was desktop bulldozer. I'm afraid I'm going to appear somewhat stupid until I learn AMD terminology.

It would be a Supermicro H8QGi-F. Nice board. May get another Real soon. Yes it has OC potential. Dynatrons work fine, wee bit noisy, but they do a decent job for the price and size. Noctuas would be better, but I went inexpensive for the first G34. ;)

Cool... thank you very much! :) Next question, what's the power draw on that baby at the wall?

Edit: ...and what kind of case are you using? The Xigmatek Elysium you mentioned doesn't appear to fit SWTX boards.
