Remember you can get an HP Prodesk G3 400 or some such for $60 refurbed with far more hardware capabilities if you don't need the portable form factor, gpio, or power consumption. It's actually a better deal for home servers.

Electricity is something you have to pay for for always-on computers: Prodesk G3: 24 hours * 365 days * 35W * 1000W/kW * $0.30/kWh = $91 Raspberry Pi 5: 24 hours * 365 days * 12W * 1000W/kW * $0.30/kWh = $31 It's likely that 12W over-counts for the Raspberry Pi 5 and 35W under-counts for the Intel chip, so it might be even worse than this.

  Right, I agree, but electricity prices are variable and location dependent, for example, it doesn't cost me 30c/kwh, it's more like 5 cents and 3 cents depending on the time. With that logic, the $20 in difference of $30 per year vs $10 per year of Pi is fairly meaningless for performance boost I am getting. If your electricity is expensive, sure, but I imagine the performance boost would be worth it for an actual homeserver that a G3 can make vs a tinkering/fun project you can make with a Pi.

  What do they idle at? I have two home servers that are essentially at idle 24/7.

  You're comparing a CPU that became generally available in 2017 or earlier (i.e., the 7th-gen or 6th-gen Core CPU in the Prodesk G3) with a more much recent CPU.

    I didn't invite the comparison. The comment I was replying to said to buy this exact model of computer instead of a Raspberry Pi 5.

  $0.30/kWh is 3x the average US price of electricity.

    california goes from .30 - .50 per kwh - thanks to regulatory capture and pg&e wait... https://www.pge.com/tariffs/Res_Inclu_TOU_Current.xlsx https://www.pge.com/tariffs/Res_Inclu_TOU_Current.xlsx I can't tell what my current rate really is, but seems like average is 38.2c/kwh

      And like a lot of things related to California, the issues there are unique to the state.

I just bought a 10th gen i5 laptop with 16gb of ram for $60 off of ebay. HP c640 chromebook. Fast enough to run a 7B LLM at 1-2 tokens/sec

the new intel m100 nuc platform chip is probably where its at. yes its double the price, but in terms of power usage its ~4 watts at the plug at 50% load, (vs 30) and more over a million times faster.
