Looking forward to this. It seems lately you can only get < 35W x86 CPUs through laptops or some very niche vendors or even mystery sellers on alliexpress. I’d like something that idles at sub 5W like ARM SBCs do but without the whole OS or boot jank.

I’m pretty sure people will suggest x86 options that fit into that description but again it looks like you have to scrape the internet for stuff like intel 1[2,3][1-9]00t or wathever the AMD alternative is.

Anecdotally, I use a CPU from an aliexpress mystery seller in my desktop machine. It's a i9-9980HK with about 40W TDP...

Which I unlocked to ~300W and installed a water cooling system.

It can idle at around 5W, but a synthetic load (e. g. prime95) quickly makes it draw full 300W and then throttle a bit. Fun stuff, definitely wouldn't do it again due to enormous strain on the PSU and an unreasonably high power draw relative to performance.

There are many many machines out there with x86 soldered CPUs all of them idling at less < 10W. E.g. ASUS PN-series with Celeron CPUs. You can even find them on physical stores. I have a PN40 idles at less than my RPI4b...
