For certain chips like the 13900HX (mobile) vs 13900K, I believe they are the exact same chip. The difference is the mobile version is binned for power usage so that it can run on a laptop.

To the extent that this degradation is wholly voltage/power related, laptop chips are much less likely to degrade. They are selected to run at lower voltages and power AND their peak boost frequency is lower.

To the extent that this degradation is caused by poor design, the laptop chips that are binned versions of their desktop chips are vulnerable to the same sorts of issues.

edit: I am familiar with the 13900HX because that's what I have in my laptop and I have been trying to follow along in case I need to RMA my laptop or do some microcode update for it.
