Power (heat) modern (especially high end) CPUs and GPUs can see some impressive reductions in power with not too much of a hit to performance.
My 4090 underclocked basically as far as it will go draws about 200 watts under normal loads, 250-300 under pretty extreme loads. But the performance penalty is only like 15%
Normally when you want to save power in a desktop device you just throw a laptop CPU or GPU in there because those are tuned for better performance per watt…. Or just not an Intel CPU because AMD is so much better in that regard.
