    Some possibly very bad news for Intel.

    Ouch... some of those benchmarks take a significant hit. I wonder if this is due to it being a quick patch to fix the vulnerability, which can be optimised at a later date, or if it's a hit we just have to suck up. I'll be keeping a close eye to see how this affects the server CPU.

    Yeah the numbers don't sound too good tbh.

    You probably understand this better than I do to be honest, but from what I read it seems its going to be more the server/enterprise and VM users that suffer the most.

    I bet there's a lot of panic with cloud computing providers - Amazon S3, Azure and the likes :eek:. Hopefully the performance impact isn't as bad as it sounds.

    Looks like desktop users are pretty much unaffected: Servers/datacentres might be more affected though.

    Just as well as I got the update this morning as I posted the link above.

    Well I must admit, following the emergency update yesterday morning I've not noticed any issues/slowdown etc here. Had a couple of rounds of BF1 and its ran just as good as ever.

    Think this has been blown out of proportion a little perhaps.

    Edit: Ah. Well thats a lot of hardware that won't be fixed then isnt' it. Even my Mb hasn't had a BIOS update since 2014. :rolleyes:

    I just hope we don't see anything exploiting this in the wild any time soon, as this mess is going to take a while to sort out.

    How long before we see new hardware without these flaws? Is it too early to assume the next CPU generation will have fixes in place?

    well, actually, you are 'vulnerable' ... it's just that someone will need to be at your PC to use the 'bug' ... if they at your PC, then you more than dorked. ;)

    Just wondering what is your view on these Meltdown and Spectre viruses on Linux, Windows and other devices. Are the software developers for all distro's /Operating Systems well behind the curve as this has been in extence for some time.

    The windows side of it is patched, as is Linux I think. But you will still need a 'Processor Microcode' update to protect you from the bugs.

    I've downloaded the Windows patch, KB4056892, on 06-01-2018 and all seems well.

    Does this give total protection from the problem or is it only partial cover? Or no cover at all? :D
