Aug 12, 2010 11:56 PM in response to Peter wiikby stuckfootage,Hey Peter,
I can't answer your question, but I can suggest an objective way
for someone to answer. Eric Ohman made a test and discussed it here:
http://www.vfxtalk.com/forum/shake-cpu-test-application-mac-osx-t15780.html
The test is pretty easy to run. Just launch Terminal and past this:
shake -checker 1600 1600 2 -turbulate 1 1 10 10 10 10 -nocache -cpu 1 -fo /shaketemp.tga -v
By changing the number after -cpu, you can change the number of threads.
Here's an example of the render times using the command line above,
runing on a 2 x 3.0GHz Quad-Core Intel Xeon:
1 CPU thread: 13.66 seconds
2 CPU threads: 7.36 seconds
3 CPU threads: 5.21 seconds
4 CPU threads: 3.67 seconds
5 CPU threads: 3.07 seconds
6 CPU threads: 2.66 seconds
7 CPU threads: 2.31 seconds
8 CPU threads: 2.03 seconds
It's cool that Shake actually uses all the cores!

Aug 13, 2010 12:31 PM in response to stuckfootageby Kevin Brock,FWIW, I just ran this code too. I'm on a 2008, Mac Pro 8-core. 10.5.8, 6GB RAM.
Numbers look like this:
1 CPU thread: 14.59 seconds
2 CPU threads: 7.44 seconds
3 CPU threads: 5.52 seconds
4 CPU threads: 3.92 seconds
5 CPU threads: 3.28 seconds
6 CPU threads: 2.92 seconds
7 CPU threads: 2.59 seconds
8 CPU threads: 2.33 seconds -

No need to download it. Just paste this in your Terminal window:
shake -checker 1600 1600 2 -turbulate 1 1 10 10 10 10 -nocache -cpu 1 -fo /shaketemp.tga -v
