Частота Процессора

[maximelson]

Всем привет. Подскажите стоит kubuntu 20.04,процессор intel i5 12400. Заметил странную вещь в простое,частоту на минимальное значение сбрасывает лишь одно ядро,остальные ядра держат частоту 2500mhz. Причем частоту сбрасывает не конкретное ядро,а прыгает по разным. Перезагрузил в Win 10,там все ядра сбрасывают до 800mhz.

А вот что выдает cpufreq-info,тут у всех ядер сбрасывается. Кому верить?

Почему решил, что это странно. Уже ни один инженер не скажет, с какой частотой будет работать данное конкретное ядро, данного конкретного процессора, в данный конкретный момент.
Все эти управления мощностью слишком сложны и давно не определяются одним "говернором". А в конкретно твоем, оказывает-ли вообще влияние этот "говернор". Тут важнее "поверстаты", "поверлимиты".
Что ты задал "режим экономии", совсем не значит, что в системе нечему заставить вспотеть твой процессор.
В качестве примера, приводил здесь скриншоты.
