On paper, the M series is faster. It's not the same situation as when AMD and Intel were suprised by Apple, though. All of the tricks that made people go for the M1 Macs and think amd64 is dead are now also available on amd64.

Price-wise, you're still often better off with amd64. People like to compare the top-end chips, but the competition for a huge slab of amd64 is a small laptop running an iPhone CPU, not the M6 Ultra or whatever the latest and greatest is today. After Apple followed the rest of the industry, the launch price advantage of the Neo quickly grew smaller, especially outside of the USA. If you want a 15 inch laptop, you're pretty deep into high end prices the moment you consider a Macbook.

In practice, getting the M series to run Linux takes longer than it takes Qualcomm to release a Linux build that works, and amd64 takes a few months of actual vendor support rather than enthusiasts hacking away for free, so in that sense the M series is still behind.
