Corona Alpha4 Benchmark scene

Keymaster, what is the cause can be that 4770k shows so long time in corona? It is may be some optimisation in code? 
It is interesting because in vray test 4770k = 3930k

I have no idea. I havent done any performance testing on these CPUs

Afaik 3930k is a 6core (12thread machine) and Haswell architecture does not have that much performance boost over Ivy Bridge. It has significant power consumption difference though.

Non the less, I am quite confident 6core Ivy Bridge should perform better than 4core Haswell.

I wonder what Vray version you did tests on, as i remember that in one of older versions, there was some problem with multithreading efficiency. In 2.40.03 everything should run fine though.

i understand this but:

this tests makes me think about that is more interesting 4770k for 370$ than 3930k for 620$ (price in Ukraine) if they both are equal

and i think all are interesting in save 250$ for buy new videocard for example))

It really depends on many conditions ;)

But i think here they tested different CPUs on same rig: http://www.tomshardware.com/reviews/core-i7-4770k-haswell-review,3521-14.html

whether there is at somebody this scene for.3ds?
есть ли у кого нибудь эта сцена для .3ds?

In simpler scenes, i4770 might come close to i3930, but in no way are they at equal perfomance in Vray :- ), wtf. I have both 3930k and 3770k (5perc. slower than 4770) and difference is exactly where it should be, close to 40perc.

Anyway, can anyone test it at current Xeon generation ? Is there any problem in perfomance scaling to dual cpus or xeon platform ? For example in 2x2867 E5 Xeons (16cores=32 threads).
