    So it is not the same ? "disclosed to Intel" and "when Intel first knew about this" ?

    Why are AMD mentioned very rarely in articles? I only read Intel this and Intel that, but according to the Meltown.com AMD is also affected by Spectre: Or is this kernel memory a completely different horse

    Meltdown.com said:
    Almost every system is affected by Spectre: Desktops, Laptops, Cloud Servers, as well as Smartphones. More specifically, all modern processors capable of keeping many instructions in flight are potentially vulnerable. In particular, we have verified Spectre on Intel, AMD, and ARM processors.
    And Meltdown is not completely ruled out for AMD:

    At the moment, it is unclear whether ARM and AMD processors are also affected by Meltdown.
    Is Intel in the spotlight because they will be hit the hardest in terms of performance with these patches? I did a few benchmark on my PC (Haswell) using Crystaldisk to see how the I/O is affected, and the only degradation I saw was in the 4KBQ1 test for writing. Not sure how this will affect much. I will try and launch a few games later aswell that's cache and CPU heavy and see how they fair.

    Absent specific performance hits relative to the Intel processor installed, I've disabled the Windows 10 update service on my oldest laptop (core 2 T 7500 @ 2.2Ghz). I'm now thinking about doing the same for our other machines.

    I thought I read that these OS patches were temporary pending Intel coming up with a more clever fix that doesn't take a (presumed) hammer to performance.

    i think the original el reg article was talking more about meltdown which is mostly an intel thing. intel talks about everyone getting hit but that's more about spectre

    Because the bug is in Intel CPU.

    If MS put the same style of fix as Linux did then you'll be hit by the performance degradation (if any) irrespective of whether you use Intel or AMD as the fix (in Linux kernel anyway) doesn't differentiate.

    Seems to be three different exploits, AMD's take on it An Update on AMD Processor Security | AMD.

    Interesting, thanks. Seems I was wrong about it being Intel only.

    It is certainly a confusing state of affairs.

    Windows Meltdown-Spectre patches: If you haven't got them, blame your antivirus


    Microsoft has warned users that its patches for the dangerous Meltdown CPU bug won't reach them if their third-party antivirus hasn't been updated to support this week's Windows security update.

    By now Windows users should have received the patches Microsoft released yesterday to plug the widespread Meltdown bug and its companion Spectre, which expose most computers and phones to speculative execution side-channel attacks that affect chips from Intel, AMD, and Arm.

    Microsoft released software updates for Internet Explorer, Microsoft Edge, Windows, and SQL Server, but customers will also need to apply firmware updates from their respective hardware vendors too.
