Apple to Buy TSMC’s Entire Supply of 3nm Chips for 2023::Apple will receive all of TSMC’s first-generation 3-nanometer process chips this year for upcoming iPhones, Macs, and iPads, according to…

    In this case it’s not truly a result of limited fab availability.

    TSMC has two main variants of their 3nm node. The original one, that Apple is using, is N3B. It has worse yields, so TSMC started work on another variant, N3E. N3E has much better yields but will not be ready until late 2023 or early 2024. Everyone else besides Apple opted to skip N3B and go for N3E. Apple, with their very consistent release cadence, didn’t want to wait for N3E. So Apple — and only Apple — is using N3B.

    Thus, we have:
    (1) TSMC only has one 3nm node in 2023: N3B.
    (2) TSMC only has one customer for N3B: Apple.
    (3) TSMC will never have any other customer use N3B, and have no incentives to build capacity beyond what is needed now.

    It’s effectively tautological that their entire 3nm allocation will be sold exclusively to Apple in 2023.

        The practical performance differences between N3B and N3E should be more or less immaterial to the end user. N3E just has a lower defect rate, meaning a greater portion of chips will be valid when made under that process versus made under N3B. There was a fairly credible rumor a few weeks ago that Apple was paying TSMC per valid chip instead of the industry standard per wafer. So for us, the end users, the cost won’t even be passed down — that’s just a cost that TSMC has to bear.

        That said, if you don’t need a new phone now, waiting is good in general. Whatever is out today, they’ll have something better next year. Wait as long as you’re willing and able between upgrades. Unless you’re absolutely loaded with money, I guess.

          Honestly, if not for security patches, most people could probably use a top of the line 8 year old smartphone, like the Iphone 6, without almost missing any feature or functionality, maybe for 20 years or more. Would certainly be great for the environment if we could use a smartphone for 15 years or more, with all the computational power already available this should be doable on the technical level. Unfortunatelly, it will not be allowed to by mnanufacturers, and we do not have a universally compatible functional linux for phones, that also can pass the locked bootloaders.

            Repair would have to become easier or cheaper if you want people to use their phone for 15 years. It’s incredibly likely the screen will break in that time frame.

              The EU already demanded user replaceable batteries, outside of that just not using software lockdowns a la Apple would already allow 3rd party repair and manufacture of equivalent parts, going even further the Fairphone is modular and with open specs, this kind of modularity and open protocols would theoretically allow smartphones to be Ship of Theseus style immortals.

            I update every 4 years, and it’s mainly just due to wear and tear and limited hardware and security improvements.

            I also just feel like you don’t appreciate the improvements that are made if you’re just getting incremental changes every year. Waiting a few years means you’re going from a ~10% improvement in performance to a ~40% improvement.

            But yeah, can’t wait for phones to become a thing that is updated when actually needed, like laptops. Not just annually because Big Tech tells us to or whatever.

              I appreciate all the technological quirks, but most people don’t really need or even use then.
              I do not know how different the current cameras are from an Iphone 11 Pro Max, but i just see people taking pretty pictures with the software optimizations (that could be updated via software) and uploading then to instagram, whatsapp etc, lots of times in compressed and digitally altered formats. Or writing text messages, using the bank app, playing shitty mobile games like candy crush, watching tiktok-youtube-streamings, paying stuff by nft, listening to spotify-other musics, etc. I really strugle to think how a common person with common habits will NEED to upgrade from a Iphone 14 Pro any time soon (for hardware reasons).

            Yeah I had an iPhone 6 Plus until 2 years ago. But I couldn’t keep using it because it was stuck on iOS 12 and all the apps no longer supported it.

            Although the screen and camera were pretty damaged, and the battery was dying, so maybe it was a good time to upgrade anyway.
