I'm not an expert, but my layman's understanding is that the lower sizes and new production techniques decrease power consumption.
The price of ongoing power consumption probably dwarfs the price of the chip itself in terms of cost of ownership in most cases.
E.g. an i7 draws 65W at idle, or about 1.5kWh/day. That's ~$0.20/day where I live, about $6/month or $36/year. Max draw is ~4x that. I've probably paid more in power to run my CPU than I paid for the CPU itself.
- humanwhosits 4y agoMost chips run rather cool, user-facing CPU in laptop/desktop/server are a bit of an exception
- causi 4y agoE.g. an i7 draws 65W at idle, or about 1.5kWh/day I don't know which chip you're talking about but a 12900K idles at ten watts.
- pure_simplicity 4y agoHe is talking about an i7 on an older node, since he is comparing the lower production cost of older nodes with their higher usage cost (electricity). I don't know what intel generation would correspond to 32nm, but that was the node discussed.
- causi 4y agoThat would be the venerable 2600K of Sandy Bridge. It idled at five watts.
