Maybe a small desktop. My desktop processor is 180W TDP (Threadripper 1950x), while some others are 250W TDP. You can also get a dual-socket workstation, for 2x CPUs (both pulling 200W each).
Thermals and power are significantly higher on desktops, it ain't even funny. Laptops win in power-efficiency, but absolute performance is always going to be a Desktop.
