I'm not denying that the problem exists, but I don't think Alderon provided enough data to come to a conclusion, unlike on the desktop, where it's supported by other parties in addition to Alderon's data (where you can largely point to 14900KS/K/non-K/T, 13900KS/K/non-K/T, 14700K, and 13700K being the one affected)
Right now, the only example given is HX (which is a repackaged desktop chip[^], as mentioned), so I'm not denying that the problem is happening on HX based on their claims (and it makes a lot of sense that HX is affected! See below), but what about H CPUs? What about P CPUs? What about U CPUs? The difference in impact between "only HX is impacted" and "HX/H/P/U parts are all affected" is a few orders of magnitude (a very top-end 13th Gen mobile SKUs versus every 13th Gen mobile SKUs). Currently, we don't have enough data how widespread the issue is, and that makes it difficult to assess who is impacted by this issue from this data alone.
[^]: HX is the only mobile CPU with B0 stepping, which is the same as desktop 13th/14th Gen, while the mobile H/P/U family are J0 and Q0, which are essentially a higher clocked 12th Gen (i.e., using Golden Cove rather than Raptor Cove)
