    i7 beating Xeons with multiprocessing off despite lower clock speed

    EchoOut Level 1

      I'm starting a new freelance job doing VFX work for a documentary and ran some tests last night between 4 computers with Multiprocessing turned off and on to help me figure out my workflow for this particular gig. Feel free to tune out if this doesn't interest you. Just wanted to report my results as they definitely made me think of this topic. It helped me a lot.


      The comp I was using in AE CC2014 was a test of a 15 second 1080p comp of a multiplaned mountain scene with Particular snow and haze, some light wrap, color correction, track mattes and typical VFX things. Small camera push with DoF turned on.


      Computer 1: MacBook Pro (2012), 2.7 GHz Intel Core i7, 16 GB 1600 MHz DDR3, OSX 10.10.2

      Multiprocessing off: 8:52
      Multiprocessing on: 5:03

      Computer 2: Mac Pro (2009), 2 x 3.33 GHz 6-Core Intel Xeon, 32 GB 1333 MHz DDR3, OS X 10.9.4

      Multiprocessing off: 18:56
      Multiprocessing on: 5:13

      Computer 3: Mac Pro (2013), 3.5 GHz 6-Core Intel Xeon E5, 32 GB 1867 MHz DDR3 ECC, OS X 10.9.5

      Multiprocessing off: 13:59
      Multiprocessing on: 4:41

      Computer 4: HP z820 (2013), 2 x 3.10 GHz 8-Core Intel Xeon E5-2687W, 64GB 1600 MHz DDR3 ECC, Win7 Pro

      Multiprocessing off: 15:30
      Multiprocessing on: 2:34


      So some pretty giant leaps for the Xeon machines with multiprocessing turned on. And then my little i7 laptop smoked them with single core processing, even with the slower CPU speed. Crazy. I guess me working on my laptop and rendering on the HP will be the thing to do on this one.
