16core opteron workstation too slow!

[Janosik]

i give here my render time from my 16 core amd machine and its very simillar to your time is : 1:47 min heh but with other vray test scene is with teapots in "museum" is time gain really not visiable so where is the problem ...... ?

I see a similar setup there, an 8 way quad core 8354 opteron, perhaps run the same test as used there to see how it performsand compares. What kind of system is that 4 cpu socket computer, is that a boxx?

About buying a new workstation, those lower end 55xx nehalems are really the bang for the buck right now, such has the 2.27Ghz.

not bad in cpu operation got intel 2 x 5410 too and ita averagely half of amd machine performance in multitread operation ofcourse ..... problem is somewhere in vray i think .....

if thats the case, a good idea would be to test with another render such as mr and see if there is any difference.

2morbid angel : yea i tried with maxwell bench , nice scaling , mr i can try too , will refer ....

2janosik: I had this speed range-problem again and again.
The some vray-scene is on my 16core opteron 2x faster as on my dual-quad-xeon.
But some scenes are slower. I don´t know why.

hmm strange .... so maybe we can do some research on this ground .....
or maybe vlado can tell something to this area .....

Take a look at my response here:

now we have the same problem as it seems...

3 machines the ones with xeon processors need 4 times (four) longer render times than the other machines...(they have 16 and 12 gb ram...at rendering there is about 3 to 7 gb free)

windows7 64bit max2010 design 64bit vray1-5 sp4 multithreading on

is there a solution... the snoop off setting didn´t do a positive...i tried to check speed step to on...but not better... any tips for other bios performance settings?
will tell later...
