![]() ![]() I'm using Ubuntu 20.04 with kernel 5.4.0 on an HP Envy x360 laptop. How can I get my new laptop to reach its maximal clock speed when not all cores are needed? with echo 0 > /sys/devices/system/cpu/cpu*/online) the laptop does reach the corresponding higher turbo boost frequencies, resulting in increased performance (a task that took on average 18.5 seconds before now takes 16.8). But they never reach the higher turbo boost frequencies. (these are 4 physical/8 virtual cores) When I throw a large single-thread load (calculating pi with mpfr) at the cpu I observe that two cores (maybe one physical core?) run at exactly 3500 MHz while the others have a lower frequency. I have a laptop with an Intel i7-1065G7 cpu.
