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.
Weirdly the temps were good, with like 20c headroom. Steve speculated it might be the VRM. It’s a weird custom mainboard with laptop RAM, but normal, socketable desktop CPU.

Errors in spec sheet and instruction guide, tools-less design, that needs tools, tempered glass panel, that isn’t glass, proprietary hardware, slow laptop RAM, CPU that runs 1.3GHz below spec, loud/annoying sound, bloatware.
Good packaging though.
What’s the point of underclocking the CPU?

Usually heat management (which means they probably didn’t install sufficient cooling).
Ohhhh, wow. Ridiculous.

Thank you!
Thank you from me as well! +1
