Regardless of price, I would like to know the combination of computer parts (gpu, cpu, mainboard, etc.) for maximum speed

Regardless of price, I would like to know the combination of computer parts (gpu, cpu, mainboard, etc.) for pytorch maximum speed.

In my experience, I think no matter how good the gpu performance is, it does not make any sense if the bottleneck happens in cpu. So I asked this question.

Sorry for not asking you a direct question with Pytorch.
