People were also saying the smartphone market is changing and Apple can't keep up and proof was a down quarter or two in the last 10 years of Tim Cook being CEO. I guess it's a perspective of does one believe Intel's glass is half empty or full regarding Intel.
To paraphrase Stephen Colbert: Intel's glass is 2/3rds empty. That last third is usually backwash.
Yup.
I'm a bit disappointed by how many people are evaluating the market based on a single product release. Is the M1 well ahead? Yes it is. Does that mean AMD and Intel are doomed? No, I don't think so. It just means they got their asses kicked, and will need several years to recover from that.
It'll be interesting how Alder Lake does. The first time Intel does a heterogenous setup (and the first time the entire line-up is finally 10nm), not counting their nobody-cared low-end Lakefield offshoot. I don't expect it to surpass the M1, but the 10nm releases of Ice Lake and Tiger Lake have at least managed some amount of catching up.
I don't think people are evaluating the market based on just the M1. Third Point didn't-- they have a laundry list of concerns.
I think a lot of people see the eventual demise of Intel as inevitable and probably overdue. We've known that x86 is a challenged architecture, that Intel's management has been a mess for decades, that their principle advantage was their process, etc. We've watched them fail at every attempt they've made to diversify their product line, lose ground to AMD on design and to TSMC on process.
If this was still just Intel vs. AMD+TSMC then I'd agree it was just a matter of catching up. In the end they're bound by the same constraints so they should be able to converge to equally effective designs.
But it's not just those players anymore. Apple Silicon not only added instruction set architecture as a free variable to optimize, but also system level architecture. The solution space just got a lot bigger and the x86 subspace just looks undesirable in this new world.
The PC architecture is based on modular commodity design, where commodity parts are interconnected by defined interfaces. This allows competition and innovation in each subsystem, and allows system vendors to mix and match among vendors. The exception, of course, is the processing subsystem which was always x86. This was great for innovation in system design over the past few decades, and also great for keeping Intel in the driver seat since they always had a scale advantage over AMD.
That doesn't seem to be the best system tradeoff anymore. It makes it impossible to optimize across the defined interfaces.
Furthermore, the x86 architecture really isn't what anyone would choose if they were starting fresh. It's too ugly to maintain. Arm may not be perfect, but it's certainly better and it's sufficiently mature. The performance difference has gotten extreme enough that even the backwards compatibility argument starts to fail-- backwards compatibility is maintained through translation with sufficient performance.
And backwards compatibility just isn't the challenge that it used to be. Once Windows, Visual Studio, and its APIs port to a new architecture (not necessarily Apple Silicon, but the inevitable PC replacement architecture), the vast, vast majority of applications will follow fairly easily. Almost everything is done in higher level languages these days.
If Intel had shown any ability to adapt in the market in the past, or to design anything other than x86, then maybe people would give them better odds, but Intel's history ain't great in these areas and the fact that they hadn't anticipated this move in the market just further supports that assessment.
Could Intel cobble together a new architecture in response to M1? Sure, but it would be brand spanking new without any of the design maturity and market adoption that Arm, and specifically Apple Silicon, have.
@cmaier estimated 2 years from design to tape out. That's 2 years for a 1st generation part to reach the market and compete with what will likely be 7th or 8th generation Apple Silicon designs?
I don't know that there's anyone out there right now that can compete with AS directly in the foreseeable future, but they don't need to. They need to put out a PC alternative to AS, and AS may be the benchmark that they're compared against but perhaps will remain a different market segment. Regardless, Intel is at a standing start as far as I can tell, and given their history I don't see any reason to expect they'll win that race.
In short, I don't think what you're hearing is entirely a case of people reacting to a single event-- I think people have a much more sophisticated view based on a fuller understanding of the technologies, players and economics involved. Like I said, I wouldn't count Intel out entirely, but this is a totally different situation than "OMG Threadripper!!! Intel is dooomed!!111".
