    I can't keep up with it any more , what's new , what's old and what is just a variation.

    That's ok, Intel can just clock it to 45.0Ghz....

    In all seriousness, I can't imagine a patch needed that will kill performance by 90%, that would essential make Intel irrelevant and unable to compete unless everyone went out and bought new chips assuming the new gen will be immune from this flaw.

    As i understand it this is unique to one form of Googles code.

    Which would likely mean Google will migrate those servers away from intel, rather than patch them.

    It's ok, it's in very very very specific scenarios

    It’s really really really not ok. It’s the opposite ok. It’s very very very bad. It’s lots and lots and lots of law suits on top of lots and lots and lots of law suits.

    Like BSD has advised if people want secure Intel systems (and servers) to turn off HT?

    Your maths are off. If you read the article and original post of the application

    So is 319.5Mhz not 450Mhz. :D

    Easy, just multiply the prices by 0.071 so the 10900K should sell for £38.34 including vat :p


    Is not that bad.... do not exaggerate the numbers... the correct speed to get the performance back should be 41.8Ghz not 45Ghz. :D
    And no we wouldn't need a nuclear power station to power those CPUs. A gas power station will be enough, for each household using Intel CPU :rolleyes:


    See above is worse :p

    Wasn't that the initial advice for the first batch of Spectre et al vulnerabilities?

    Didn't know they had also said it for this very specific kind of work load.

    Even at £38.34.......................i bet Intel would still be making a small profit. Probably even more of a margin than most local shopkeepers make.

    In what instances will my CPU be gimped down to 450Mhz then?

    Gotta love journalists who go for sensation.

    There is no doubt for whatever reason people are really wanting to find vulnerabilities in intel chips right now, but again attacks on them? hardly unending, they almost zero due to not been practical.
