Apple silicon is great for low power desktops and laptops, but they don't actually have groundbreaking performance relative to what we've got in the server space. If you dropped the M2 Ultra from the $4000 into a server, it would perform about the same as a $1500 AMD 7950X3D based server (this is a common budget server setup with ECC) in CPU tasks. Stick a common GPU in there and you're running circles around the M2 Silicon in GPU tasks.

The Apple Silicon is great at really low power work, but if you dial desktop or server GPU power limits down they also become quite efficient. The marginal cost of electricity is cheaper than buying more hardware, so nVidia and others run their parts deep into the diminishing returns part of the curve to maximize performance at the expense of power efficiency.
