Is laptop CPU and PC CPU comparable?

[VL_Hermes]

if i wanna find out how good is a laptop cpu compared to another, can i use the pc cpu counterpart to know how big of a difference they are? or cpu laptop and pc laptop of the same series is much different so they're not comparable at all and i must look into each one as laptop cpu. (i wanna use linus video as comparison,but he only reviews pc cpu)

Here is a benchmark set that includes both mobile and desktop CPUs. Generally desktop CPUs are faster, as they have a higher power budget. But the difference isn't super big. At least if you compare the same core counts to each other.

You ideally need to look at each laptop itself, not even just the CPU. Mobile platforms are usually power and/or thermally constrained, and that limits their performance potential. On AMD side, the mobile CPUs are architecturally similar to the desktop APUs, but they have less cache than the full fat desktop CPUs for example. On the Intel side, there are some mobile CPUs that do not have any desktop counterpart e.g. Tiger Lake, Meteor Lake.

the thing is with ryzen cpus (and K series intel cpus) on desktop, they will turbo indefinetly unless it throttles, on a laptop, it might hit 5 GHZ briefly but will quickly drop down to base clock, usually under 3 gigahertz
