Anecdotal evidence, but I had both a 13th gen and 14th gen Intel CPU with the bug that caused them to over time, destroy themselves internally.

The most-user-visible way this initially came up, before the CPUs had degraded too far, was Firefox starting to crash, to the point that I initially used Firefox hitting some websites as my test case when I started the (painful) task of trying to diagnose the problem. I suspect that it’s because Firefox touches a lot of memory, and is (normally) fairly stable — a lot of people might not be too surprised if some random game crashes.
