Apple M1 or PC with graphic card for large 4K TV Three.js visualisation

We are building a Three.js 3D configurator for closets.

Our clients wants to showcase the configurator on multiple large 4K TV screens in its showroom.

We are not sure which hardware we should recommend. We will be testing a Mac Mini with the new M1 chip.

Are there benchmarks available that compares Apple M1 vs a regular PC + graphic card specific for WebGL usage? Or does someone else has a hardware recommendation for this kind of usage?

(I hope the question is not too ‘general’ for this forum).
