    Re: AMD CPU L1-data cache vulnerable to sidechannel attacks

    Interesting how only one of the Zen2 processors were tested. I wouldn't call that a comprehensive list for research. Also interesting is how yet another Intel vulnerability with the management engine (hard to exploit but will likely render DRM useless on entire generations when it is inevitably exploited) and then this comes out but seems very well publicised.

    How very interesting.

    AMD has responded to this, mind including this?

    Is it possible to have the actual quote? A lot of media are blowing this out of proportion considering it relies on a previously mitigated exploit to be vulnerable to commit the attack.

    Intel 'sponsored' and from what I've read elsewhere, biased testing by not using fully update setups....

    Then it's likely getting 'pushed' to the front of every inbox because it's AMD even though in the grand scheme of things it's pretty minor compared with the holes that keep turning up in intel hardware...

    Re: AMD CPU L1-data cache vulnerable to sidechannel attacks

    Wow. The spectre of this almost makes me meltdown over my decision to buy AMD over Intel. I should have listened to that load of zombies and bought Intel even though its current chips are overpriced and comparatively underperforming, not to mention security flawed. Oh boy. Quick I'd better cancel my order stick with my AMD chip as planned.

    Stop that. Stop that right now. Bad Dad jokes should be illegal.

    I've just bought an AMD Zen2 chip and the more of this stuff that happens, the happier I am to be rid of Intel and that I haven't handed them any money this time around.

    but... but... but I'm not a dad!?! Oh no. It's got me before my time. Farewell youth!

    I've almost got my 3900x system finished. Not regretting it.

    if companies did as much research with Amd's procs as they do with Intel's I would not be surprised to find Amd has just as many vulnerabilities as Intel's, if not more.

    Why?

    Security is largely about company culture, and the two companies are not alike.
