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.

What device is that chip in and at what frequencies is it running (by number of cores in use)?

[mkopec]

Lenovo 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.
