If I run a benchmark for a program on the M1, that's a single data point. It's hard to call a single data point "linear", "quadratic", or anything else... and you can't really put multiple benchmarks on the X-axis, because they're measuring different things.
What would even make it (whatever "it" is) "extremely unlikely"? People have had over 6 months to run benchmarks on the M1. Surely you can find a concrete answer to your question that doesn't involve random speculation on internet forums?
Based on my own experiences, I have no reason to believe that the M1's performance starts tanking if you run it for longer than a few seconds, in case you're implying that the other processors will "catch up" if they have longer to get up to speed... why would they? That makes no sense either. Longer compilations are faster on M1 too, relative to my Intel hexacore MBP, from what I've seen in the past. I mean, obviously, right? Why wouldn't they be? Intel's processors change frequencies in milliseconds... it doesn't take them minutes to warm up.
The M1 isn't a silver bullet. AMD makes laptop processors that are more powerful. But the M1 is still really good for what it is, and those AMD processors consume notably more power than the M1 to achieve their performance.
