IIRC they’ve already started going after anti-adblock updates to Chromium.

Yeah, Apple’s secret sauce isn’t necessarily perf/watt in an all-core load (although they’re obviously near the top there as well) but in idle power consumption. I’m guessing that M3 does better here, but I remember seeing a Phoronix test/review that showed that when capped at 15 W, the latest Ryzen laptop CPU beats the M2 in all-core workloads, although the M2 gets better battery life in “normal” workloads.
