This "old-technology" machine (socket 1366) performs pretty much simillar to i7 5960x ... and this is what I expected

Oh u did nvm, Sorry my bad!

Just ignore this post...

please, can you share how you over clocked your Xeon's.

He did not OC his xeons. They are unOCablea as far as I know.

that's what I thought, but he says he did, didn't he?

Got a load of these turning up this week, would love to know the benchmark not OC's, and again, interested to know how you OC'd them?

Just finished building a new rig and hope to finally test this scene on it tonight, Ran a test render last night and held steady OC'd at 4.4ghz stable Specs below:

ASUS Rampage V Extreme MB
16GB DDR4 PC4-24000 (3000MHz) Ram
i7 5820k 6 core
M.2 128GB drive (primary OS)
240GB SSD (secondary drive Programs)

The key component is MOBO. Noramally xeon's are not overclockable ... but there is one motherboard (Evga SR-2) that allows you to do this (only for socket 1366). The problem is this motherboard is no longer manufactured. So the only way to get it .. you need to find it on ebay/amazon. The problem (again!) is that it gets pretty pricy and there is not so many of this MOBO on the market.

I will not test this CPU with no OC (dont want to mess with my OC settings) but I will have soon another rig with very similar dual xeons: x5675. Of course I will do the test and share the result as soon as get new machine .

It seems a bit strange but also a bit normal... after all you are looking at 4.2 ghz vs 2.0 ghz.

I have an SR-2 and have overclocked socket 1366 xeons. But there is no point anymore, the 1366 cpus are out of date and slow now. A single new i7 is equally fast or faster as a dual socket SR-2 overclocked and half the price.

I don't think there is any point with xeons if you require value for money. If time is more important than money, by all means, but the i7 overclocked is easily the best value. If getting the i7 allows you to upgrade twice as often as getting a dual socket xeon then your better off with the i7 as the next gen i7 will be faster than the last gen xeon.

I'll put up a bench mark in a moment to prove the point.

[werticus]

twin 1366 6core xeons at 3.2ghz + 3 generation old i7 (4 core) at 3.4ghz and another 2 gen old i7 (6 core) at 4.4ghz in DR and it gets 1min 55seconds which is a fair bit slower than the current 8 core i7 at 4.4ghz gets on its own. Probably uses about 4x the electricity too.

Because the scene is too light, so it is not good to make a judge for machines with many cores. As this makes my new machine 5.6 times faster than my 6 years old i7 @3.55GHz.

So I tried to a 3000 resolution (embree on) 3:34 this makes the new machine 6.9 times faster than the old
And a 4000 res. (embree on) 5:53 and this makes it 7 times faster.

Our latest couple of machines have been XEON based and we are very happy with them. However, we are considering getting a couple of overclocked (professionally - not by me!) 8-core i7 based machines. From this thread, it seems they are good value, but in terms of stability, assuming the machine is built well, how to they compare with XEONs?
