Curious if this affects laptop chips, or just desktop? I've got a 13th gen i7 in my laptop that so far has not had any problems (well, except keyboard issues that seem to be due to the manufacturer), but would like to know if there's a risk of CPU issues in the future.

TFA sources Intel as saying even they don't know whether Laptops are affected, given similar circumstances.

It’s answered in the FAQ at bottom of article that they are still investigating.

I’ve seen videos on YouTube where they say intel claims the issue with laptop chips is a separate issue which the videos go on to say that it is a strange thing to say if intel isn’t sure about the root cause of either issue.

  Could it be that the manufacturing defect only crashes the CPUs at a higher voltage, and the 13900HX/14900HX mobile CPUs run at a lower power (157 W) than the 13900K/14900K desktop CPUs (253 W)? If so, then Intel might be trying to spin this as the high voltage being the cause rather than oxidation or some other manufacturing problem.

    My understanding is that the chip is able to request higher voltage from the mainboard as demand increases. And it’s allowed to request an unsafe level of voltage. This is particularly problematic under high load.

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.
