It's not good idea to do these comparison based on isolated part like CPU only. While that is what established the performance, in the overall scheme, with the price of 32GB DD4, SSD, quality PSU, X99 motherboard, it's not everything.
For node it's absolutely perfect though, it made 5930k literally obsolete and useless.

For workstation, even the 1000 euro pricemark makes 5960X worthy candidate. It's basically must buy.

The last time I checked the price was not so far from the 4770k, I don't see why do you think the 5960x is a must when the price has a 270% relation vs a 123% in performance :P I don't see the benefit of investing in it, can you explain it a bit more?

Cheers!

5960X features basically the same (or better) overclockability than 5820K, so they can be close (25perc.) at base clocks, they really come apart at the top range (4.4 Ghz), where the performance you get from single CPU machine is rivaling the top Xeon range (as those have locked multipliers) and far precedes 50+perc. Sure, the CPU itself costs 3 times as much, but if you're comparing full workstation, for example 32GB DDR4, 256GB SSD, quality parts (NH-D15, platinum grade PSU 750W,etc..), GTX970, you end up comparing 1700 euro vs 2500 euro machine (prices out of head), one being 50perc. faster in rendering performance. And that's pretty good deal.

But you can achieve similar performance with both procs (with the exception that the 5820k has 6 cores, and the 5960x has 8 cores), so why use such proc if the overclocking is more or less the same, you can save the money for other things, like better parts, or a render node, I can make you a 5820k now for 800€ +/-

Of course I can understand what you say, but i've developed a way of work and it's never have a better workstation than the nodes of the farm, in fact, have better nodes than workstations (or at least equal), this way I can have the render times in control without surprises hehehe

Cheers.

Because every performance increase matter to some. There are situations I require such instant feedback I don't bother with DR at all, so having the most powerful workstation I can get gives me the results I need. Nodes simply help with the overall rendering time.
5960X can be seen as luxury but imho it's only small price increase to some for the value you get back. With up to 19 score in Cinebench11.5, you're getting almost 65-70perc. of multithreaded performance of 2p Xeon E5 26xx v2/v3 WS system, but with superior singlethreaded performance, so you're getting quite a lot of value in one package (for up to 3K is not a lot for truly high-end workstation).
Same can be said for priorities, perfomance/value simply stops being single condition to take into account at some point. But that's already another issue.

From practical standpoint, hypothetical 800 euro 5820k is useless for me for example. I need 64GB ram in every single machine, and that alone is 800 euro for DDR4, such feature already minimizes the role of CPU's cost in overall scheme.

In the end it's like every Hardware choice, you sacrifice something over something based upon your needs and priorities. But 5960X, even for its price, it literally rocks.

Ivy Bridge v2 Xeons can't be overclocked because they have locked multiplier ???? why cant be ???

juraj, why would you need 64gb in every node, isn't 32gb more than enough for rendering?
Thank you.

This is not overclocking in same way as you do with unlocked multiplier (K-series) i7. He's using BCLK straps (or FSB) instead, and he's basically limited to 3-8 perc. at cost of instability (it's connected directly to PCI lanes too), and it does depend heavily on unit you're lucky to get.

Mmmh I don't share your thoughts, while I can see the benefit of having a higher single threaded performance for some tasks, I can't see that an inctrease of in price of 169% more over the 5820k has any leverage, when you are talking about the ram, well, the 5820k and the 5960k shares the same type of ram, so I still don't understand why you may want to invest so much more for a little more performance, just a 23% more of performance, no matter if you compare it with xeons, because those are totally different computers, no overclock, more expensive parts like the motherboard, more power drain, more noise, more maintenance, and yess, I like more a single CPU computer than a multiple cpu computer.

I'm comparing two CPU's from the same family that can live inside the same system, the difference is that you invest 169% more money with one than with the other to get just 23% more of power, I can't see the benfit of it :)

Cheers!

Maybe another good and cheaper candidate based on 2011 is the 4930k, +/- same results than the 5820k:

Interesting.

Cheers.

Ok this became absolutely pointless discussion I don't think you're even reading what I write.

SHD look better because i posted the corona benchmark scene too ;)
