I'm not sure if that's a big deal with a single box.

Threadripper is only 300W+ under load. Idles for the CPU are ~100W for the whole system. (https://www.kitguru.net/components/cpu/luke-hill/amd-ryzen-t...)

GPUs are similar. GPUs take ~20W while idling, but 300W or 500W while under load. FPGAs are also similar.

-------

The total system idle of a Threadripper + 2x GPU + FPGA rig probably is under 200W.

If you happen to utilize the entire machine, sure, you'll be over 1000W. But you'll probably only utilize parts of the machine as you experiment and try to figure out the optimal solution.

A "mixed rig" that can handle a variety of programming techniques is probably what's needed in the research / development phase of algorithms. Once you've done enough research, you build dedicated boxes that optimize the ultimate solution.

By power I meant compute power. Did not mean power draw.

Ahh, gotcha. I guess I misunderstood.

Your earlier comment makes sense now that I understand what you're saying.
