Hope some mod will take this to HW section.
This choice depends purely on your needs and expectations and of course...budget.
Good
workstation with 5960X will come you at around 3000 euros including high-end GPU.
Good
workstation with 2p 2680v3 will come you at around 6000 if you include high-end GPU.
5960X offers higher overclock for both single and all cores, up to about 4.4 Ghz per average chip under best cooling. This means you can reach about 40perc. more performance for both single and multi-threaded tasks.
2680v3 offers only mild turbocore feature and about 4-5perc. BLK overclock if you use Asus workstation motherboards. That in reality gives you 2.9-3.0 Ghz for multithreaded rendering, and 3.3-3.4 for singlethreaded workstation tasks. More than enough.
That concludes to fact that 5960X makes slightly better workstation horse, but 3.3+ Ghz for Haswell chip is well beyond any penalization that you could even notice compared to running super-clocked i7.
In multithreaded tasks, 5960X is about 80-90perc. as powerful as single 2680v3 in default turbocore, and roughly 20perc. faster when super-clocked to maximum potential.
To take out: High end dual Xeon (2680V3 + and higher) will be twice faster than 5960X, and cost twice more. That makes it very easy choice...it depends how much money you're willing to spend.
And:
Have a look in the benchmark thread here and compare Corona's results with official benchmarks (for example whether a speed ratio between two certain CPUs is comparable to the ratio from the same CPUs from a dedicated benchmark site).
No. The benchmark is faulty, and based on old Corona core. It basically ignores the performance of dual CPU setup.
I found that fore some reason dual Xeon setups do not scale linearly and that a simple GHZ
Than you found wrong. I run quite few dual-xeons...and yes, they scale almost linearly. Until you reach the too many cores of top models, and then certain applications including Corona have problems utilizing all the cores, but this is software issue and not HW.
