PC Spec. for Katago #851

I know that GPU is more important than CPU for Katago performance.

But, I'm curious if there is a performance decrease when using a low-end CPU with High-end GPU.

ex) Graphic Card : RTX 4070 ti or Better CPU : i3-12100F or worse ※ Is that sufficient or need better CPU?

If the CPU is sufficiently weak, there might be. Normally the CPU finishes all of its work faster than the GPU, so then the time is determined just by waiting for the GPU to finish and the CPU doesn't matter. But if the CPU is very slow and can't do its work fast enough then the CPU would matter.

I don't know about specific hardware - you would have to test it yourself, or find and ask people with hardware similar to yours to test it.

Is there a linear relationship between CPU load rate and visit/s? Or is it related to block size?
