    you won't update because you have nothing to hide... Why?

    Re: Intel processor security flaw requires OS kernel level fix

    It appears that Intel CPUs since Westmere include something called PCID (Process-Context Identifier) that helps mitigate the effects to some extent - although the fixes have to consider this instruction set extension, and thus might be coming later than the "quick" fix that'll come out this month.

    It seems the bug kills SSD performance massively, if you are a hard SSD user. Bad news for some.

    So in actual fact, very few "core" chips are in the "you MUST upgrade" catagory, and those that are, are so old that really those people should be considering an upgrade anyway?

    I suspect it kills all disk I/O massively, but it's less noticeable with hard drives as they're already slow.

    Re: Intel processor security flaw requires OS kernel level fix

    So, if I ran that file and it says I'm vulnerable, what do I actually have to do to fix that?

    Hope that your motherboard manufacturer has pushed out the update IME software

    Yes, that might be the case. Intel back to 4% down and AMD up 7% now.

    Edit:

    BBC News have finally got an article up:

    "Intel did not respond to requests for comment"

    Apologies. So there is now another hardware level bug with Intel CPUs? I guess we all now know why AMD CPUs have run slower, because they're actually doing things properly it seems. I definitely think I'll be upgrading to AMD next round.

    It probably explains why the intel ceo sold 11 million in shares just last month....https://www.nystocknews.com/2017/12/...poration-intc/

    That's a juicy story.. Yes great timing there! The Intel cpu security flaw story is the most read on the BBC news site now.

    Well, if you don't mind the hackers gaining access to protected memory areas which hold secure data such as passwords, banking details etc, then you are correct. Why not post all that info on Twitter and save them the trouble of hacking you
