differences between Opteron and Xeon?

[Guest]

hello, I want to build a workstation for 3d rendering and so forth.
I want to also "rent" it out for other people to use the power for their own usage.

I was looking at a 10 core Xeon E5-2670 v2 and putting it on a dual socket motherboard so I could upgrade later.
But I could also get a 16-core Opteron 6376 and put that on a dual socket motherboard for a much lower cost.

what would be the pros and cons of choosing either or these?
the Xeon would be $1,500 and give me 10 cores, 20 threads-
the Opteron would be $700 and give me 16 cores/threads

Once upgraded to a dual cpu setup, would the Operon (32 cores) or the Xeon (20 cores, 40 threads) be faster?

I want to do other things while it does work, so I would need a lot of ram... 64GB sound like enough?

I want to be able to use it while doing other things in the background- So I would need a lot of ram...can I jam non-ECC ram into these 2400/2600mhz ram into these as long as the mobo supports? or do these have limits?

EDIT: for the Xeon, I was looking at the http://www.newegg.com/Product/Product.aspx?Item=N82E16813131861 or the http://www.newegg.com/Product/Product.aspx?Item=N82E16813131817

For the Opteron...I don't know yet...http://www.newegg.com/Product/Product.aspx?Item=N82E16813131643 ?

Same as comparing the 8 core FX8350 to a quad core i5. AMD gives you more cores, but each core is considerably weaker. Intel gives less cores but each core packs a LOT more punch.

aren't server CPUs a lot different? the FX chips have some weird sharing thing with the cores...I could of sworn Opterons don't have that...

Nope. Same Bulldozer/Piledriver microarchitecture that inherently has weak IPC.

okay- Intel looks good as the ASUS Z9PE-D8 mobo actually supports higher clocked ram-

Wouldn't the AMD be better for multiple tasks do to the larger amount of real cores and cache?

I would end up doing quite a bit at once and I am wondering if the single core performance of the Xeon is worth 2x the cost if the AMD would have more cores.

The $650 6 core e5-2630v2 are similar performance to the $700 opteron 6376. That's just how weak the cores are compared to intel. Might I suggest the 8 core e5-2640v2 at $920. The performance increase for the 10 core does not justify the price increase.

now THAT puts it into better perspective! I was originally looking at the e5-2630(non v2) before looking into a higher core cpu
...no the price increases doesn't justify it as much, no...

It's even cheaper on superbiiz http://www.superbiiz.com/detail.php?p=E5-2640V2
the asus board I'm looking at even lets me run it turbo'd 24/7 so that is pretty good...

I like this cpu more...I think I'll wait to see if anyone has a better suggest, but this looks pretty good! Thank you!

just a few addon questions-

Is there i difference buying OEM and retail? The OEM is $25 cheaper so I wonder...

and would it be considered okay to get these cpus used? considering intel chips don't have pins on them I wouldn't think they would get damaged.

Oem just doesn't come with a manual since neither come with a heatsink. If you want to try used it's your choice. I buy used a couple of times, haven't had any issues.

Who the hell needs a manual for a cpu
I would probably be using a Noctua air cooler...could go dual H100i but I don't see the 10C diff to be that big of a deal...

Then I'll probably buy them used, what will happen? A portal opens and demons come to take my Board to silicone hell? 😉

Thank you for assisting me, you even went a little above and beyond~
