Mac Pro? First Ultra class chip came in Mac Studio. They missed an opportunity to call it a Mac Pro Mini.
They've actually improved cooling a fair bit. The two chips I mentioned though are definitely power hungry though. That Intel chip can use up to 115W sustained. I don't think I want to know what the burst power is. The larger MacBook Pro might actually be able to get close to that (I think Apple's solution is on the order of 100W if you push both CPU and GPU simultaneously). Yeah the Apple system is considerably lower power once you start looking at GPUs as well.
Edit: actually looking at it the AMD Chip is only rated at 55W similar to Apple's CPU cores. I think in practice it will be higher though.
Edit 2: Sustained boost of 128W apparently on the AMD chip. Sheesh.
