    Yeah.
    That's what you get for setting your roadmaps on fire.
    Applies to Intel, too, since Intel goes byebye soon.

    What was wrong with Llano?
    AFAIK it was a pretty capable chip with a GPU performance similar to the HD3850/3870 which is pretty much what AMD had promised, and years ahead any iGPU Intel could provide for years to come.

    It was unapologetically late.
    (reminds you of 10nm haha)
    Yeah but the CPU part was years behind Intel when it actually launched.

    So you're suggesting Apple wanted Llano but it was too late?
    You've been recently posting a lot of stuff without anything to back them up, and honestly, this falls right into that pile too. Any references to AMD APUs and/or CPUs in macOS came years after Llano at least as far as I'm aware and even then they're more likely just stuff left in AMD drivers from their common base than anything else
    Last set of them came up earlier this year when _rogame spotted them, but same happened few times earlier too

    Yeah lol.
    They were also the sole driving force for things like Crystalwell.
    Because Llano in macs never reached product development stage due to them solid ass delays.
    As did plenty of other things like CNL-Y macs or 1st gen ARM mac test boards and whatever else.

    The very first time Llano appeared in a roadmap it said 2011, which is when it ultimately launched.
    Back in 2007 AMD had a codename "Shrike" APU planned for a 2009 debut of their Fusion concept, but it was cancelled less than a year later.

    So whatever you're talking about, it's probably not Llano.

    I could see Apple being somehow vindictive about what happened with e.g. Kaveri, which had two GDDR5M PHYs for high GPU performance, but fabrication of that memory was scrapped when Elpida went bankrupt, which makes it not AMD's fault. Also, I doubt Apple would ever want to adopt bulldozer CPU cores.


    In the end, what I'm saying is you're not making much sense with your Llano delay allegations. The 32nm Llano was never delayed. There was a 45nm Shrike that got cancelled, but it's a very different chip.

    The fact that you consistently fail to back any of your claims with any source at all makes it all even harder to digest.

    Llano was truly late launching in H2 2011 given it was just a shrinked K10 with a GPU. Even the completely new arch - Bobcat - launched in Jan 2011. So maybe that awesome 32nm delivery from GloFo was the culprit.

    Anyway, Apple migrating to a dead K10 architecture followed by utterly sad Bulldozer-based chips (ok, up to Carrizo-refresh) sounds hilarious given their premium branding. If there ever were such talks, Apple would likely back off at the very moment they were shown the APU roadmap.

    Yeah.
    The first die is a go.
    Nah, only Genoa is 2021 for select customers*.
