If you're only seeing 6 render threads on a 12 core machine. If you're only seeing 12 render threads on a 12 core machine. Nevertheless, you should be able to open Activity Monitor and see the "CINEMA 4D" process sucking up anywhere from 1600% CPU to 2400%.Īgain, if you're only seeing 6 render threads on a 6 core machine. If you're using the XMB (physical) renderer, then you won't see any yellow squares at all since the XMB sampler is a brute force ray tracer (there is no progress per say, the time you let it run determines the quality of the finished image). You see them during the GI computation and raytracing phases of the render. The render threads manifest as those yellow buckets/blocks/squares, one per thread. A 12 core machine should spawn 24 render threads.
Therefore, under Cinema 4D- a 6 core machine should spawn 12 render threads. This allows the hardware to execute two threads at once per core. This means that one physical core appears as two logical cores to the operating system (and by extension, any programs running under that). The CPUs in a modern day Mac Pro are hyperthreaded. I am just concerned something may be wrong with the 12 core? It was a very subtle difference but still a 12 core should be blowing away the 6 core! does it have something to do with the amount of ram i have in the 12 core? does each processors need a certain amount of ram to function at optimum power? where as the 6 core has 12 gigs all to itself and the 12 core has 6 gigs to each processor only.?
I just bought both computers and i am quite concerned why my 12 core (19000 range qeekbench) would be slower than my 6 core (15000 range qeekbench). Mac pro 2012 6-core 3.33GHz 12 gigs DDR3 1333MHz ram ATI Radeon 5770 Mac pro 2012 12-core 2.4GHz 12 gigs DDR3 1333MHz ram ATI Radeon 5770 I was suddenly shocked by how this would ever be possible.
I have been doing some of my typical 3D work in cinema 4d R12 and today i discovered that the extensive 3D animation i was rendering out was rendering faster in the on screen preview on the 6-core than my 12-core. I have a bit of an unusual observation that i found this afternoon.
