AMD revenue:

2018 $6,475
2017 $5,253
2020 is also when they launched Zen 3 and the corresponding EPYC (Milan, IIRC). Furthermore, it takes years to build a presence in the server market. So, while Zen 2 EPYC (Rome) caused the industry really to sit up and take notice, they couldn't turn on a dime and start cranking out lots of new server designs based on the CPU in that same year.
2020 is also when they launched the Ryzen 4000 series of laptop processors, which combined up to 8x Zen 2 cores with their integrated graphics. This came at a time when Intel's laptop offerings still consisted of either Ice Lake quad cores or Comet Lake 6-core CPUs.
In other words, you're weaving a narrative that omits many key aspects, in order to deprive AMD of the agency of its own success. Yes, they benefited from Intel's misfortune in ramping up their 10 nm nodes, but even that only happened because AMD had a ready and viable alternative. Then, AMD built on that success, instead of squandering it.
So, I'm not endorsing everything
@Lewinator56 , but I think your take errs
at least as much, in the other direction.
this gen is about twice as efficient as anything else, at least at low power?! ( "Low" power meaning 100w and below)
No, it's not 2x at 100W! At 100W, the 9950X is about 85% as fast! In fact, at
no point in that graph is the 285K ever 2x as fast as the 9950X!
Also, you're singling out their chiplet-based CPUs and overlooking their monolithic products.
