How efficient is your cruncher?

[krusha03]

The couple of servers that I've measured tend to be pretty close to the TDP number but then I normally use the minimum amount of ram, only one hard drive, minimal graphics, etc.

Maybe that 2666 is part of the 2660 line - http://ark.intel.com/products/81706/Intel-Xeon-Processor-E5-2660-v3-25M-Cache-2_60-GHz

Some info i managed to found is that it's an amazon cloud exclusive cpu with up to 36 virtual cores or something like that. Weird...

Thanks Bro.
Tomorrow I will be posting the 2P

 

[Norton]

I'm overdue for getting one of mine on the list

I'll try to get the data from my Z77/2600k rig posted later today (Norton03 in my specs)- it gets around 6k ppd at 120w iirc

* EDIT here's one of mine:

Norton | Corsair HX650 | Core i7 2600k + GS8400| 1 HDD | 118W @100% (8 threads) | 5984 | 50.71 | Ubuntu 12.04 LTS | crunching 24/7

Those v2's look pretty sweet - 70+ is very good.

They are amazing

Airmont and Carrizo-L is what I'm looking out for. Wonder if they'll come in packages I like. Still need to post main rig, will probably do that soon.

I think these 2 socket motherboards sip too much power.... Too bad there is also no option to change voltage or multiplier... In the end it might be more efficient to go for higher TDP CPUs due to the large overhead the MB has. But yeah those Xeons v2s and i7s look really good efficiency wise. Table updated

Edit: Hmm why the big diffrence in PPD between @manofthem and @xvi i7s?

All of the dual-LGA1366 systems that we have are built on the Intel 5520 chipset. It's a 65nm part rated at 27W. I'm honestly not too surprised.

Indeed, I am very disappointed of this Build
And I guess that the new 2P Machine that I am building it will consume the same
4 x Xeons L5640 2.26GHz = 370W

Edit: what a mistake, 4 x Xeon V2 @ 3.8GHz would consume less power.

Don't feel bad. The dual octo core machine has a TDP of 150w per chip and it draws a little more than 300watts - 2687W - first generation. That's why I'm actively looking for 12 and 14 core v3 chips.

There were a couple of 12 cores for a little less than $600 each on ebay a couple days ago but they went fast. I probably should have pulled the trigger on those but I really want the 14 cores.

I was thinking something like 40 watts extra but the board uses almost as much as power as the CPUs themselves. Here for example they said the board + 2 cpus use ~140W

By comparison, I'm rather happy with mine. ~240w from the dual-E5620s for ~9k PPD isn't bad (although, not great: the 2600k gets 7k from 150w). Although I know in Germany electricity is a lot more expensive....

But the initial investment would be much higher right? i mean 2 L5640 + motherboard cost as much as one Xeon + motherboard

145€ motherboard
178€ cpus
36€ ram
80€ coolers
50€ hdd
70€ Case
70 power supply
50€ pin repaired

Total 679€

No one forced you to post here but if you are claiming that show the numbers to support it

Sorry for the late response:

HammerON | EVGA 500W | Q6600 @3GHz 1.26V + ATI 3650 | 1 HDD | 173W @ 100% (4 threads) | 2454 | 14.18 | Win 7 Pro x64 | Dedicated cruncher

But Xeon e3-1230V2 + motherboard will cost you about 330 euros right? Then you will have to by an extra of everything for 2 (except coolers) It's not that bad man

Added. And damn that's less efficient than my FX

 

[HammerON]

Here is my main rig:
HammerON | Corsair AX1200 | i7 4770K @4.4GHz 1.232v GTX 780 (SLI) | 2 SSD | 211W @ 100% (8 threads) | 5266 | 24.96 | Win 7 Pro x64 | Crunches 24/7, except 1-2 hours a night for gaming

Time to (finally) submit my little ARM box. Time for SCIENCE!

xvi | 5v wall wart | Rockchip RK3288 @ 1.8GHz + Mali-T764 | 8GB eMMC | 9W @ 100% (4 threads) | 723 | 80 | Android 4.4 | Cheap eBay RK3288-based no-name media center box

Awh! Couldn't quite best Agentskid, but I can't complain with the results. I think I got mine for ~$80-90, so the initial investment isn't too bad, I'd say. PPD/investment could be better since for the price of about 3 of these, one could have a half-decent dual Xeon rig.
I think I'll see about picking up another one soon, but I'd like to check out something with an ARMv8 core, or at least something like a newer Exynos. It's hard to find anything too new in anything except a new phone though.
(Part of the reason why I want a second one is just so I can call them my "ARMada of crunchers".)

I will post my 4P System results as soon as i can

Points of note: the bigger rig is about 95% efficient in that the power from the socket is only 5% higher at 252.7w
The same cannot be said of the bronze psu trying to run at 5% load. This is closer to 65% efficient.
Close attention must therefore be paid to psu selection or multiple boards could be run from one psu or maybe one of these j1900 rigs could be piggybacked onto an existing rig.
