I just went comparison shopping. A fully loaded M1 Ultra has 64 cores and peaks at $8,000. That means this speed test needs a reevaluation. If you wanted to do 24 cores (still faster than these specs), it's $3,000 - a lot of bang for the buck in comparison. Compared to an $8400 AMD rig; It has a 3970 with fewer cores, going to get more expensive than the Mac with the 3990. The graphics card is a GPU Quadro RTX A4500 20Gb 4x DisplayPort - not sure how that compares at all. Again, the RAM and GPU on the Mac are not really comparable to PCs as far as I can tell -- it seems to use a lot less RAM for the M1 due to its architecture for the same process -- though, video buffer matters on AI and video games - not sure if anything is going to really max out the 64g shared memory. There are a lot more development apps for AI and tools for Unreal Engine and other specialized apps on Windows at the moment, but, I expect a lot of progress in Neural Net-related tech because it's standard on the Mac platform. There's also a lot of room for optimization. Apple wins hands down in bang for the buck for heavy-duty creative work, not sure about the video cards, and Windows still has an edge for developers.

The threadripper because I don’t care about having an interstates GPU, I would rather have the increased power.
