*the computer is passively cooled and fully powered off of solar. It is actually repurposed from the components of my first homelab build (cca 2021), it sports a 8-core/16 thread Ryzen 5 and 64GB(!!) of DDR4 ECC RAM which I did not dare to look up what you'd have to pay for today (I got the two 32G modules around 200€ each, a bit pricy even then, as these are server/workstation-grade sticks).
By turning off PBO ("turbo") I still get plenty of perf out of the CPU (~10K multi-core Geekbench 6) while making sure the passive copper heatsink doesn't break a sweat. This also helps keep peak power draw at bay (65W measured absolute peak), which meant that I could power the whole thing off a 80W wide-input PicoPSU and completely avoid the AC power brick — it is directly hooked into my 24V battery pack via the solar charger. I am in fact also replacing the (odd, 19V) power brick of the monitor with a similar setup using a voltage regulator.
So sustainable efficiency,
massive data centers. -

@flaki Keyboard not weird enough, cannot process.

@duncan_bayne tbf this is a 5750GE with a 35W target TDP, this APU is intended for stuff like those Lenovo miniPCs
