Best CPU for playing 50 HAP videos simultaneously with composite TOPs?

Hardware
1

My project is basically 200 HAP videos, 50 per scene, playing simultaneously into several composite TOPs and out through several spouts/siphons/ndi. Might convert this in the future into instancing SOPs onto a rectangle screen with rendering TOP (no other manipulations - would look identical to a movie-TOPs composite network).

Some softwares either

  1. Take advantage of every core & thread (like a threadripper)
  2. Or are single-threaded (fastest CPU wins)
  3. Or can take advantage of only a few cores/threads, but not all

In my situation, what would be the ideal CPU? Is HAP mainly using the GPU or CPU? Would instancing with SOPs bring that workload to the CPU?

Hi @bluewhale,

from the docs:

Hap is a video codec that performs decompression using a computer’s graphics hardware, substantially reducing the CPU usage necessary to play video.

50 simultaneous HAP videos sounds a lot - especially reading the data from a harddrive might be your main issue?
What’s the resolution of the videos and what is your output resolution?

cheers
