Ryzen 7 Mini-PC makes a power-efficient VM host

Power efficiency &amp; power management really need to be a focus. I have an old Gigabyte GA-AB350-Gaming-3 I got when I eventually upgraded to a Ryzen 1700 (now 5800), and I: a) cannot get this system to idle below 80W after stripping non-essentials, b) suspend or sleep in any way (the system goes down but I literally have to pull the plug, wait, and replug it in to turn back on). I&#x27;ve tried undervolting, spent hours trying to tune power profiles &amp;making sure maximum PCIe aspm link savings are active; the system is just a brute, and unmanageable. It feels so cursed &amp; has been such a leaden disappointment I&#x27;ve tried to carry for so long; it has truly shattered my faith in AMD in general.<p>I&#x27;d rather not get a G core, but hearing that this system idles at 10W is incredible. That&#x27;s what my 8600t HP tiny PC&#x27;s idle at. That would be stellar.<p>I&#x27;d love to see more reviews and write ups include power consumption, and also ideally suspend capabilities. Ideally wwol would also be verified working.

Seems strange that they compare this to a raspi in the conclusion rather than one of the fully integrated mini PCs with a soldered down laptop CPU, eg from Minisforum.<p>Besides, the barebones unit is over €200, the 8700G is €300, and RAM is €150-250, for a total of €650-750. Meanwhile an 8GB Raspi 5 is less than €90 all-in and a 7 node cluster of these would use about as much power in total as the 8700G does on its own.
