It's a laptop chip, and a 15w one at that so I wouldn't exactly say that's high-power.
Eh, at it's minimum configuration. I run two 5500u in similar setups that are almost always at 30W+ with pstate in its epp setup. In the scheme of things, not that much I suppose, but I run a couple little n100's as well that almost max out at 15W, and my Synology units have these crappy Marvell chips that use less than 5W. The 5500's are vastly more capable, but y'know...it's all subjective to the user.
You know, I think I did the thing I always do and forget how bad the idle power for Ryzen cpus are due to how they're architected.
Like, my home server is a 10850k, which is a CPU known for using 200+w... except that, of course, at idle/normal background loads it's sitting at more like 8-15w. I did some tweaking to tell it to both respect it's TDP and also adjusting turbo boost to uh, don't, but still: it's shockingly efficient after fiddling.
I wouldn't have expected a 5500u to sit at 30w under normal loads, but I suppose that depends on the load?
Well it's an APU, so it's running pretty much everything. Running any normal network services pretty much means it's in use.
In the context of having a normal light bulb back in the day on 24/7, it's still more efficient, but there are other options out there than use much less power is all I was saying. If you're heavily transcoding, I don't think it matters at all.
Right, but you're pulling way more power than the homeserver I'm running is, and at 10-15w it's doing frigate + openvino based (on the igpu) identification on 4 cameras, usually 2 jellyfin streams at any given time, 4 VMs, home assistant, and ~80 other containers plus a couple of on-host services for NAS duties (smb, nfs, ftp, afp, nginx, etc.)
I was just surprised that a Ryzen U-series chip would be worse re. power usage.
