I'm talking specifically about their mobile lineup, not desktop. And more specifically the performance to power efficiency the M series is getting. It is more than 2 generations behind.
Each Ryzen mobile generation also improved efficiency, in particularly the last generation (AI PRO 300).
Intel, on the other hand, started a few generation ago with an edge in terms of efficiency, and now they're behind; they are definitely the one that fell asleep.
The fact that ARM may have unreachable efficiency doesn't mean that AMD, as x86 producer, is doing nothing.
