    If its a modern intel laptop, its likely the PL2 clocks. The PL2 level is basically a time interval where the cpus run at a higher boost clock than sustained turbo, and ia defined to run at that for a short time period (e.g about 40 seconds) before clocking to the standard boost clocks (PL1). Its why laptops heat up fast and ramp very quickly. It makes processors seem faster than they are. (Similar to like running speed in a 40 yard/meter dash vs a marathon running speed)

        I see. I also have an old laptop (4th gen i7). I personally use throttlestop to limit its turbo clock speeds just for sake of noise.

          I decided to try undervolting my laptop’s cpu and found the intel-undervolt tool. It seems that reducing cpu voltage by 25mV has solved the issue.
