Choosing hardware for rendering


In general, the more cores the better.

Here’s some general guidelines for choosing hardware:

  • Arnold scales linearly with increasing processor speed
  • Arnold scales well to multiple cores
  • For a rough estimate of  expected performance, you can multiply the clock speed by the number of physical cores.
  • Get enough RAM to hold your typical data sets (you probably should run
    some tests with your most challenging scenes)
  • Hyperthreading on Intel processors usually gives about 1.2x speedup on average.
  • If possible, running some tests is the best way to choose the best hardware for you
