I9 12900 - přímo z intel ark
Processor Base Power: 65W
The time-averaged power dissipation that the processor is validated to not exceed during manufacturing while executing an Intel-specified high complexity workload at Base Frequency and at the junction temperature as specified in the Datasheet for the SKU segment and configuration.
Maximum Turbo Power: 202W
The maximum sustained (>1s) power dissipation of the processor as limited by current and/or temperature controls. Instantaneous power may exceed Maximum Turbo Power for short durations (<=10ms). Note: Maximum Turbo Power is configurable by system vendor and can be system specific.
Tolik k tomu, co píše Intel u jednotlivých CPU.
Co se toho, co tu píšete o autech, týče...:
Doporučuji pustit PC,, fungovat na něm třeba 3 dny a změřit průměrnou spotřebu CPU. Pak by to možná odpovídalo přirovnání ke spotřebě auta.
