Honestly, this is one of the reasons I think Intel's stock is likely undervalued at this point (not that I want to invest my money with management I don't feel confident in).

Intel is facing a lot of threats and they rested on their laurels. At the same time, Intel is still 75-80% of the market - even as AMD started killing Intel in performance for several years. I'm less sure that Intel will hit its fab milestones than Intel's press releases, but I'm also not sure that AMD can really take advantage of that. AMD is reliant on TSMC's capacity and as we've seen recently, AMD often has to wait a year or two before it can use TSMC's latest processes. Even AMD's upcoming Zen 5 processors will be using TSMC's 4nm N4P process (with future Zen 5 processors expected to be 3nm). If Intel is able to get 18A out the door in 2025, Intel's fabrication will certainly be competitive with what AMD can get (and likely quite a bit better).

From what I've read (and I might be wrong), it sounds like Intel is moving to High NA EUV soon (now-ish/2025) while TSMC is waiting until around 2030 (https://www.tomshardware.com/tech-industry/manufacturing/tsm...). Is TSMC falling into the trap of letting a competitor out-invest them - the same trap that Intel fell into ~2012-2022? Probably not, but it does seem likely that the advantage TSMC had will taper away over the next couple years - assuming Intel isn't full of crap about their progress.

Even if TSMC maintains a lead against Intel, can AMD take marketshare? Specifically, can AMD produce as many chips as demanded or are they somewhat limited by how much capacity they can get from TSMC? For example, if people want X number of AMD server chips, does AMD manufacture 25% of that number and 75% of customers buy Intel chips because that's what is available due to AMD's lack of fab capacity? I'm not saying that is the case - it's a genuine question for someone that knows more about the industry than I do.

We do know that TSMC has limited capacity. Apple tied up TSMC's 3nm capacity such Apple is the only company shipping 3nm parts. It looks like Intel will be the next company shipping 3nm parts with their Lunar Lake using TSMC's N3B process this fall.

I'd also note that Intel's fabs aren't unlimited either. Meteor Lake moved to Intel 4 in December 2023, but Emerald Rapids (server) remained on Intel 7 at the same time. Intel can't just churn out as many Intel 4 chips as they'd like.

I too wonder how/why AMD is still below 25% marketshare given Intel's issues. I wonder if AMD has limitations on how much fab capacity it can get which is stifling attempts at gaining marketshare. At the same time, it looks like Intel is on a course to fix its issues - if one can believe what Intel is saying. If Intel is able to ship 18A chips in 2025 at volume, it seems like it should fix the big issue that Intel has been facing - inferior fabs. AMD has been able to out-do Intel in part because it's been able to rely on TSMC's better fabrication. Is this just a blip where Intel looks bad 2020-2024? That's a genuine question because I don't really know enough about the industry. Maybe someone will say that Intel's PR is mostly bluster and that they're still being run by beancounters trying to optimize for short-term profits. Maybe someone will say that Intel is investing in the right direction, but there's still a lot of risk around pulling off High NA EUV for 2025. Maybe someone will say that Intel is likely to hit their milestones and will regain the title of best-fab.

However, given that AMD hasn't been able to really hammer Intel's marketshare, it feels like Intel has more staying power than I'd think. Again, like the parent comment, it's always puzzled me that AMD hasn't gained a ton of marketshare over the past 5 years.
