Hey,
I've been playing around with a few rigs and there wattage usage. I'm looking for quick CodeProject AI response times with the minimalist power usage. Thought I would share some kill-a watt usage on two powerful setups. Got my hands a new Ryzen 7 8700G with 780M iGPU. As well as a 12700k undervolted and lowered pl1 and pl2 . Only had Blue iris running when testing the wattage. Not super scientific. I'm Considering running the Ryzen setup for the long haul. The biggest issue I've seen is the detection times are greatly dependent on the clock speeds of the GPU. Which most setups are basically idling (low clock speeds and having to ramp up to detect). Nvidia GPU's benefit greatly from Performance mode. At the expensive of power draw. I didn't get into tuning the Ryzen iGPU yet. Granted at stock it's pretty quick. Thanks for looking.

Ryzen 8700G
DDR 5 5600 32gb
1tb Nvme
5tb 3.5 hdd
Psu sf 450 platinum
Average around 50-55 watts.

Intel 12700k
GPU 4060 single fan. I've ran it in performance mode(basically never clocks down/idle) 15-25ms detection times. As well as Normal mode 60-110ms.
DDR 4 3200 32gb
1tb Nvme
5tb 3.5 hdd
Psu sf 450 platinum
Average around 95-100 watts with GPU performance mode.
Average around 75-80 watts with GPU normal mode.

If you want to save some more watts try setting the Maximum processor state to 99%

You may also want to experiment with adding a few Coral TPUs and testing the performance/power there. They only use a maximum of 2 watts each. The next release of CPAI should have much improved multi-TPU support.

If you're interested in this route, don't use the USB TPUs unless you have to. The USB interface seems to have all sorts of emergent properties that don't play nice. I've been experimenting with 8 TPUs in my machine for low power reasons.

The 8700G build dropped 8-10 watts. Cruising at 40-45 watts. Nice little tip/tweak.

@mailseth

Ive tried the M2 coral pcie version about 6 months or so ago. Too many canceled attempts. I did See MikeLud1 post in GitHub about training the Coral for his models. I'll revisit when it matures.

My i7-8700 system did the same thing. This is totally illogical. The info I could find says reducing the maximum to 99% disables turbo boost in the Intel chips. My CPU usage was a bit under 20%, so turbo boost shouldn't have even been running. With turbo boost off I expected the CPU usage percentage to go up, but it did the opposite. The CPU percentage went from the 16-18% range to 12-14%. Very illogical. There must be more to it. This is a big deal for a machine that runs 24x7!
