Depends. The cpu attempts to hold the maximum possible speed on any cores that are in use.

On my water cooled and specifically tweaked desktop- yes. It’ll hold max boost indefinitely, even with all threads. (getting to about 80c after 10 mins). Single-thread max is faster, and it’ll hold that as well.

My laptop will pull power within 15 seconds and be down to base clocks in a couple mins. Unless I set it down outside and it’s very cold.

Most un-tweaked chips are going to be below 25 watts with a single core loaded, and lots of laptops can cool that without any problems.
