It’s about half the cost to build your own based on Ryzen thread ripper and DDR5. I’ve done this before however, it’s not ARM64. It also requires like 1000w power supply. Can you build a machine just as capable? Yes. Will it be as efficient? No. Will it be Arm? Probably not. That said, I run Apple MacBook Air as my daily so YMMV.

*edit* ok a bit more than half. Chip shortage has scalpers sitting on threadrippers.

If you leave it switched on using 5 cents worth of electricity an hour, how long does it take to cost more?

Do you need a Threadripper to compete with M1 Ultra? Ryzen 9 7950X seems pretty comparable and doesn't require a 1000W PSU unless you must pair it with a 4090 or something.

Depends, how cache friendly is your workload? The M1 ultra has more than 4x the memory bandwidth of the threadripper. Of course the GPU makes a big difference in cost and power use. If you need a 4090, there's nothing comparable. But if the Apple iGPU is enough you save a ton of power and space.
