It's certainly closer than it has ever been, the mobile Ryzen 4000 series is a massive improvement across the board. At the high and medium end, it completely dominates Intel.
Where Intel still rules (in x86 land) is that all day battery life. They're simply better, for now. I think mobile Ryzen 5000 may take over even that niche, but it remains to be seen.
From all the tests I've seen, AMD has a power consumption advantage compared to intel. This directly translates into longer battery life. While there's probably situations where Intel has better battery life due to software maturity, we've already seen tests where in low load situations amd is beating intel. During high load it's not even a competition at this point.
