I don't think this is the case.

Intel Panther lake beats the M5 in GPU and multi-core performance, and is only behind in single core (and not by much). Panther Lake is also on some Windows laptops that trounce MacBook battery life (e.g., Framework 13 Pro according to Just Josh Tech medium-brightness productivity benchmarking).

The Snapdragon X2 Elite beats the M5 multi-core performance (the HP Omnibook Ultra 14 is priced identically spec-for-spec with the MacBook Pro with M5). Still behind in single core and probably graphics, but squarely in the same realm.

Both of these chips are within small deviations of the M5. We could call Intel and Qualcomm 1 year behind at best.
