During lockdown I had the Intel Mac pro in my home office and my electric bill doubled with that thing on. It also pushed out so much heat, but at least the chassis design was whisper quiet. I don't know, by the end of it all, I was so happy to get that heavy thing out of my house.
Sure, it was definitely the fastest thing to enable the tools I needed back in 2020 and I was extremely happy to have it. It also became obsolete once the M1 had native tooling ready a couple of years later. Soooo yea.
I guess with all that excessive space in that chassis they can overclock the system and squeeze out every bit of performance. The PCI expansion could be good for production studios that need it. At that cost level though, the system will have to outperform anything you can find on the windows side.
