Help understanding hardware and rendering terminolgy


So I’ve trying to figure out the render farm I’m working on. But anyone who knows anything about it is in India and only communicates pretty sporadically.

Here are some questions I have.

  1. What is the difference between a thread and a core? I thought I knew the difference but then my VFX supe told me they were the same thing. That’s not what I had learned, but I wasn’t about to argue with him about it.

  2. When you are talking about render hardware and blades…what does a slot refer to? One of the people I was talking to said that on our farm: we have machines with different numbers of cores. 24, 48 and 72. The 48 core machines have 4 slots. The 72 core machines have 6 slots for 12 threads and 4 slots for 16 threads.
