That's Intel's boost behavior, AMD is much more linear. My 4750U in performance mode never exceeds 25W and settles at 23W under sustained load.

- hajile 4y agoWhat device is that chip in and at what frequencies is it running (by number of cores in use)?
- mkopec 4y agoLenovo ThinkPad Gen1 AMD, Arch Linux, acpi platform_profile = performance When running stress-ng, measured with turbostat: - 4.18 GHz single thread consuming 9W - 3 GHz 16 threads consuming 25W, ramping down to 2.94 / 23W after a couple of seconds and when compiling Linux on 16 threads it stays at 2.85 GHz / 23W In performance mode it does run at 80 degC under sustained load, so usually when undocked I just leave it in balanced mode where it's capped at 20W short / 15W long Also worth noting is that in low-power mode (11W / 11W) it'll still hit max single core frequency possible.
