    its timing based attack, already dealt with in firefox months ago.

    except this is a hardware fault and cannot be patched only on application/OS side.

    no, honestly this happens double on Intel archs then ARM v7/v8 + AMD all toghether because they never cared about cache synchronization issues in the name of +1/2% score in synthetic benchmarks.

    There's a Windows update pushed out today that address another Spectre variant. And now this.

    I don't know about you guys, but if AMD hadn't pulled a rabbit out of the hat with the Ryzen line of CPUs, I'd be pretty dejected right now. Thankfully 7/8 of the desktops in the house now are on AMD.

    So basically Intel has been charging higher prices while cutting corners for years to get ahead of AMD (IPC-wise)... and now the security fixes will cost Intel's users the performance boosts that they payed for. Great!

    Certain activities are better done behind airgap. For day to day banking and sensitive things, one can always get some cheap device with linux oriented on security and not do anything else there.
    "mitigations" ... my English may not be very good, can you explain meaning of the word to me?
    And article is year old and not related to this.

    I am honestly curious how this changes CPU's performance... mitigation after mitgation, windows patches that cripple your performance by up to 15%, now disabling hyper threading... it's as if Intel did everything wrong since they introduced the core2 architecture. And even if they did not do wrong, they still "missed" some details. In the last ten years.
    Every year there's another problem that eats away half of their "7%" yearly performance increase, exaggeratedly speaking. So basically Intel offers even less than what I though, they're losing ground to AMD if you take everything into account. "Older" node, AMD IPC catches up, CPUs will probably run just 500MHz lower than Intel and not 1GHz like it was at times, AMD doesn't need 2/3 major security mitigations of 2018 / 2019... they're cheaper...

    If I was personally responsible for sensitive data and valubable IT infrastructure, I'd get the f away from Intel. I would simply not have trust in their security anymore.
    Every 6 months there's another issue, requireing a OS fix and / or a microcode update.
    First breaks stuff again, second isn't even availble! I STILL cannot get all the fixes for my CPU unless I work them into the BIOS myselves, right? Thanks... but this is enough for me personally.

    the articles reference to timing changes directly influences this new bug.

    I agree.
    I almost fried my Motherboard Bios last time, trying to update the microcode for Meltdown/Spectre.
    (Bad Bios flash,managed to get replacement Bios chip)
    Will be going back to AMD anyway now.
    X570 here we come.

    Definition of mitigation
    : the act of mitigating something or the state of being mitigated : the process or result of making something less severe, dangerous, painful, harsh, or damaging

    You AMD fanboy's realize, this vulnerabilities have been around since 2008 or something and no one has been attacked due to it.... now there are actual patches out in software and soon micro code updates. Safer today than yesterday.

    But go ahead, make a mountain out of a ant hill and enjoy your lower performance AMD in every application.

    "A micro code here, a micro code there."

    Let's translate that...

    "A performance hit here, a performance hit there."

    And this keeps adding up everytime a new hole has been found. By the time everything has been patched i'm down to a stock i5.

    I kind of like Asus boards due to their ability to flash custom BIOS through flashback.

    It does not matter if Asus fixes things, the community can fix it and share these modified BIOS files.

    You do realise you're posting the same arguable rubbish in two threads, because in one people were already not sharing your opinion? ;)
