It's very hard to know which processor did what by just looking at the tiny picture.... are the Core i7, still the best bang for the buck?

4x Opteron 8393 SE on a quad socket (TYAN - S4992) MB

... sounds expensive

Get some Istanbuls in there!

... sounds expensive

4x Opteron 8393SE - US $ 1.530,50 -> eBay USA - less than two Xeon X5580

Get some Istanbuls in there!

...could be one of the next steps

hmmm...
The closest I could find was this:
http://cgi.ebay.com/Supermicro-H8QME-2- ... 286.c0.m14

any good? (oh, wait... I think those are dual core, not quad cores )

hmm.. how about this one: http://cgi.ebay.com/Opteron-8354-Quad-c ... 286.c0.m14
(that is like $320)

one of my Quad Opteron setups is a H8QME-2 I bought for 200 Eur ($ 287) - but you have to take care, only Mainboard Rev. 2.01A has "Shanghai" / "Istanbul" (six-core) support.

I bought 3x 4 pcs. of Opteron 8360 SE on ebay USA - the highest price was $ 1.300 for 4 ($ 325 for one CPU) - so you see it may be quite cheap to get a good Setup for Maxwell

the NUMA architecture of AMD Opteron is perfect for Maxwell because Maxwell depends on good CPU - RAM performance

interesting... take a look at the motherboard: TYAN S4985G3NR
http://www.newegg.com/Product/Product.a ... 6813151085


which you can add: TYAN M4985-SI Expansion Board
http://www.newegg.com/Product/Product.a ... on%20board



So, if add 8 quadcore Opterons from my previous link: http://cgi.ebay.com/Opteron-8354-Quad-c ... 286.c0.m14



and then a whole bunch of these:


we should have a fairly decent system for maxwell

Okay stop dreaming, back to work...

[arch3990]

nice work with the pics - but why didn't you just take this one:



Tyan Transport VX50 (8x Opteron Sockel-F, dual PC2-5300R reg ECC DDR2)

http://www.tyan.com/product_SKU_spec.as ... =600000101

8x Opteron 8435 (6-core) - 48 cores

[arch3990]

Get some Istanbuls in there!

4x AMD Opteron 8439SE - 2.80 GHz (24 cores): 3m23s / 3157.18






4x AMD Opteron 8439SE - 2.80 GHz (24 cores) - OC to 3.1 GHz: 3m02s / 3171.85

[micheloupatrick]

Impressive!
What's the real (no eBay) cost of the system?

[arch3990]

... I can't tell you - HP offers something similar - (HP ProLiant DL585 G6 w. 4x 8439SE) - this system costs (without HDDs) - 13445,50 Eur (in Germany)

(but this system cost less than an actual Mac Pro Octo with 2.66GHz)

[dmeyer]

(but this system cost less than an actual Mac Pro Octo with 2.66GHz)

Ummm, how is that possible? The 8439SE chips alone are $2500+ USD each...

[arch3990]

you need a lot of patience and a little bit of luck... with e*ay

(these ones came from e*ay UK and were brand new and sealed)

[Leonardo]

no 32 cores for me... I went ahead and bought a: Silverstone tj07 case, core i7 920, EVGA gtx 260, CORSAIR 1000W PSU, everything else is classified

I'll be water cooling it and OCing it, as soon as I get another job that pays for the parts

(pics will come soon)

Yes, the quoted Mac Pro is $4,699...
And you have to buy a motherboard (the Tyan sells for $499 at Newegg), a power supply, some ram, a hard disk drive, a case, a 3D card, keyboard...
you certainly got an incredible deal on those Opteron.
