what is the xeon equivalent cpu for the i7-975x ?

Postposted on Wed Dec 19, 2012 5:36 am

hi !





i proceeded some tests about performance of our firm ERP on my desktop computer.

And from the old xeon 5130, i gains 15s on the longuest task ! (during 30s on the xeon) what is a big deal !





i own a core i7-975x cpu, and i'd liek to know what is the xeon architecture and performance equivalent of it ?

Just remind my i7 is a 4xcores of 3.33GHz release in year 2009

thanks for help

Best regards,

Xeon W3580 for single socket version

Xeon W5590 for the dual socket version

The Xeon chips are half-locked, but they can support ECC support DIMMs (provided that you have motherboard that supports ECC).
Ivy Bridge i5-3570K@4.0Ghz, Gigabyte Z77X-UD3H, 2x4GiB of PC-12800, EVGA 660Ti, Corsair CX-600 and Fractal Refined R4 (W). Kentsfield Q6600@3Ghz, HD 4850 2x2GiB PC2-6400, Gigabyte EP45-DS4P, OCZ Modstream 700W, and PC-7B.

thank you.

ouch, release date are old too, i though they would be newer like xeon E? something....

Your i7-975 is also pretty old. The W3580 almost a i7-975 with a different label on the box.

If you want a new xeon of comparable performance to it, then something from the E3-12xx range would do. E3-1240 at 3.3GHz. It will run a bit faster than an i7-975 or W3580 as it is slightly more efficient (maybe 10%) per clock, will run even faster when just running a single thread as it will turbo boost to 3.7GHz, and uses less power. Also much cheaper than the W3580 launched at. Or you might want to look at the E3-1290V2 as being the flagship single socket xeon, if time is valuable, or maybe a dual socket solution, if you can scale to 32 threads with a pair of E5-26xx. A E5-2687W core should beat the W3580 despite a slight clockspeed deficit, and you get 2 processors with 8 cores (16 threads) each, so twice as fast if you have enough threads.

thank you for your reply.


in fact, i was planning the E5-1620 cause it is cheaper (very) and seem to be as (even better) quick that the i7-975.

Even if the E3-1290V2 will be faster in single thread (what my app really need and my app is not scallable over threads), it is really too expensive for only 100MHz and energy-powerless : more than the double in price compare to the E5-1620

Also consider the other Ivy bridge E3-12xxV2 chips, especially if you don't need a powerful GPU, and would be happy with the integrated graphics. The E5-1620 is Sandy Bridge EP which uses socket 2011, which is usually more expensive than the socket 1155. It does give quad channel ram and more PCIe lanes.

more details for best recommendation

If you only care about single threaded performance, I would suggest the E3 system over an E5 system.

I'd suggest the E3 1245 V2: It is "only" 3.4ghz compared to 3.6ghz however it is an Ivy core and IPC is ~5% better than the Sandy core in an E5 so its almost even.

The motherboard will be cheaper, and the system will use less power too. You could put the savings towards bumping the E3 up to a 1270 or 1275@3.5ghz.

Do you need iGPU or plan to use another? Can save $ and power by leaving the iGPU out.
Is 32GB of ram enough or do you need 64GB or even more? E5 can go really high on ram (I've seen 256 on single socket, even more on dual) with a board that takes registered DIMMs but it sure won't be cheap.
Is this machine doing anything else? Need a lot of I/O? Sometimes you can save a lot getting onboard parts, e.g. I know of an E5 motherboard with dual 10GbE and a SAS controller that is almost as cheap as buying just the NIC by itself.

Also are you actually going to use ECC ram or VT-d?
If not, a 3770K (or 3570K) on a Z77 is the cheapest way to get fastest single threaded performance. (non-K on Q77 if official VT-d support is needed)
Even if you don't overclock it per se, quite a few motherboards (asus for example) can keep the turbo pegged for you, which is sort of like a 'free' ~400mhz.
