    so which one saved pore power or performance? Next time please try to think harder. Thanks.

    i've probably missed you rebuilding all my closed source games for arm

    Phoronix: NUVIA Published New Details On Their Phoenix CPU, Talks Up Big Performance/Perf-Per-Watt

    Since leaving stealth last year and hiring some prominent Linux/open-source veterans to complement their ARM processor design experts, we have been quite eager to hear more about this latest start-up aiming to deliver compelling ARM server products. Today they shared some early details on their initial "Phoenix" processor that is coming within their "Orion" SoC...

    LibreOffice runs on ARM since 2014, stop snorting apple product dust https://www.phoronix.com/forums/foru...it-arm-aarch64
    See here on Debian packages https://packages.debian.org/sid/libreoffice

    It's NOT about recompilation and porting. It's about OPTIMIZING for performance, stability
    This is true for Power but not for ARM. All decent software is usign NEON extensions on ARM or has ARM assembler optimizations.

    AND new hardware features like built in A.I. and Neural Net processors that Intel nor AMD CPU's have built in like ARM or their Apple or Qualcomm derivatives.
    Unless you are actually doing tasks that need AI, there is no use for "neural net processors" (a fancy name for an embedded GPU, because that's what that is).

    ARM, Apple, Qualcomm and Mediatek are ALL going to beat Intel AND AMD to 5nm. And that's REAL 5nm not optimized 7nm but will be marketed as "5nm". And by the time even AMD gets to real 5nm ( and forget about Intel as they are hopelessly lost in fabrication now ) ARM, Apple, Qualcomm and Mediatek will be chugging merrily along at 3nm.
    Considering that everyone apart from Intel is manufactured by the same fabs, I don't see how that is even possible.

    With even MORE Power per Watt efficiencies AND ALSO just plain more computational OOMPH. Not to mention built in AI Engines, Neural Net Engines, GPS, Vision Engines NONE of which is in ANY x86 processor either from Intel nor AMD.
    That's a fancy name for a GPU, bro.

    I am NOT an Apple fanbois.
    Yes you are. You are posting a ton of bullshit propaganda about Apple, and caring about nonsense like their market evaluation.

    EVERY SINGLE DEVICE running ARM and a version of iOS/MacOS all completely optimized and performanced tuned to ARM.
    And will still lose badly to "unoptimized" Linux probably, just like MacOS or iOS does today.

    There’s also the problem of Apple’s minuscule market share. I can tell you’re in the US because Apple seems more widespread here than elsewhere. They have 10-15% of the smartphone market. Their total PC share is 3%, laptops like 7-10%. That’s not leading anything. Worse, I see the company making some of the mistakes they made in the early 90s. They might still succeed, but it’s not the sure thing you make it out to be.
    Thanks for typing that out. I was about to write the something similar. I don't care about architectures and which one "wins" the pc-market. But why on earth would he think, that apple plays such a big role here? Just because they have their own ARM-"implementation" like 30 other vendors? People already/still falling for their marketing-BS?

    x86 is here to stay because of the existing software ecosystem around it. It has been declared as dead or obsolete many times in the last 20 years, but I see little indication that it's going away any time soon. Unless nuvia presents something that is vastly superior to x86 in perf per dollar AND comes with tooling/software at least equivalent to x86 servers, it'll remain a niche product or die like most of the rest of the "disruptive" arm server startups.

Everybody poo-pooed those announcements as well. Until Microsoft...as they always have done...copied Apple as well and turned the lumbering Wintel Titanic around to follow Apple's lead.
    Floppy drives lumbered on for ~7 years after Apple dismissed them. Flash unfortunately lasted a decade longer as well. When they disappeared it was because they were obsolete, not a long delayed reaction to Apple’s decision.

    The A series chips don’t perform as well as they seem to in benchmarks. The benchmarks perform differently because they’re on different hardware. There’s no question they’re currently on top of mobile CPU performance, but I’d like to see actual results of the chips doing desktop tasks, not the oft-mentioned Geekbench results.

    Your snark about Linux being tied with x86 is dead wrong, though. It started briefly as a 386 specific project, but Linux has been multi-platform forever, and runs fine on ARM. I think you’d be surprised how poorly optimized Mac OS actually is. OS X started as a very clean product, implementing advanced features in an ideal manner, but it’s accrued so much crap in the last decade that I think it’s more technically indebted than OS 9 now. Apple’s contemporary disrespect for developers, that increases with every subsequent version, reminds me of Microsoft in the late 90s.

    I agree that we’re overdue for change, but I think looking at one thing we have and saying it’ll leapfrog another is awfully naive. I’d rather expect the unexpected and be completely surprised.
