Meltdown affected Apple's ARM CPUs as well. If you read the linked support doc, you can see that they released Meltdown mitigations for iOS as well.

Yes... like I said almost exclusively affects Intel CPUs. Just because 0.001% of non-Intel CPUs are affected while 100% of intel CPUs are, doesn't make Intel's strategy forgivable. I'm tired of seeing it echoed everywhere.

  Tired of seeing what? The truth? The truth is that all these chips are affected.. it's one thing to ask for clarification on the numbers but this is not "fake news".

    It's misleading, that's all there is to it.

      I think this is an example where the truth misleads the reader more than a lie (aka. simplification of fact)

  Do you know how many CPUs Apple makes? It's certainly an order of magnitude larger than all the unaffected vendors combined...
  - tomxor 9y ago
    Do you know what proportion of the number of ARM based CPUs that Apple has made or distributed in it's devices over last decade that are affected? Do you know what proportion of the number of x86 CPUs that Intel has made over the last decade that are affected?
    - tarlinian 9y ago
      Are you really implying that the fact Apple doesn't even disclose which processors were vulnerable to this a positive?
      - tomxor 9y ago
        No. You really don't need that information to infer roughly what proportion are affected. There is very little information out there about specifically which ARM chips are vulnerable, but it's always "High performance ARM designs". This is one of the few references: > Intel is the company most significantly affected by these problems. Spectre hits everyone, but Meltdown only hits Intel and ARM. Moreover, it only hits the highest performance ARM designs. For Intel, virtually every chip made for the last five, ten, and possibly even 20 years is vulnerable to Meltdown. https://arstechnica.com/gadgets/2018/01/meltdown-and-spectre-heres-what-intel-apple-microsoft-others-are-doing-about-it/ https://arstechnica.com/gadgets/2018/01/meltdown-and-spectre... Do you really think Apple has been using such a processor going all the way back to the first iPhone and iPad? Not to mention there are far more android phones and tablets than there are Apple ones (revenue !== number of devices) "High performance ARM designs" weren't really a thing until more recently, and they aren't going to be anywhere near a majority used in these devices... Remember what you are comparing this to. The statement I'm complaining about is already factually wrong by assigning the Meltdown vulnerability to AMD, and then additionally it's extremely missleading by implying equality in it's application to ARM and Intel which is anything but. I'm honestly surprised how many of you replied to my comment in disagreement, I suppose it just shows how well PR FUD works and spreads if it's not dispelled loudly enough. Still I expected more on HN.

    No it's not. There are far more embedded ARMs shipping every year than Apple could ever dream of selling.
