    Intel processor security flaw requires OS kernel level fix

    But there could be performance impacts of between 5 and 30 per cent depending on task.

    Re: Intel processor security flaw requires OS kernel level fix

    If I receive a serious performance hit due to their blunder then I will be rightly furious and I can see some compensation claims coming their way. Although with that being said, on the flip side, if only Intel performance gets hampered with these fixes, then AMD have just closed the gap for free and the competition is back on!

    Bittersweet.

    Re: Intel processor security flaw requires OS kernel level fix

    So which modern Intel CPU's don't suffer from this then if, as suggested in the article, I wanted to go out and buy a new processor to avoid the flaw?

    As it seems to cover the i7 8700K which is a recent chip the answer may be none!? That's a bit of a shocker.

    I'm am heavily interested in the performance impact of Hypervisor Clusters. This could cripple or poison Intel in this market.

    They all do, just newer CPUs have less of a perf impact.

    Re: Intel processor security flaw requires OS kernel level fix

    Up to 30 percent will kill some cpu's, my mums atom based tablet is slow enough as it is lol.... maybe this is intel's way to force upgrade old pc's, it's not like we have any other reason to upgrade these days.

    They've seen how well it works for apple by using the software to 'slow down' their older models for the benefit of it's users of course so they're now having a go at it under the guise of a bug fix.

    Then they've hardly picked a good time with AMD at it's highest point for well over a decade and generally offering better value for most mid-high end users (the likes who will have the most to lose from this), Ryzen 2 coming and presumably their APU lineup will be getting fleshed out too.

    As advertisements go it would hardly be a great incentive to upgrade your Intel CPU for another Intel CPU.

    Re: Intel processor security flaw requires OS kernel level fix

    30% is no joke. As someone who is on Sandybridge/Ivybridge/Haswell for my Workstation and Server/Gaming PC/Laptop this could have pretty significant ramifications for me if it hits workloads I use.

    Goddamn it DDR4 memory manufacturers...

    Re: Intel processor security flaw requires OS kernel level fix

    I wouldn't say gaming might be unaffected based on the Phoronix tests, a lot of those games tested are either GPU bound or they are benching in 4k (why on earth 4k when testing CPU performance?).

    And for windows gaming I'd wait to see what Microsoft does when they patch it.

    Re: Intel processor security flaw requires OS kernel level fix

    My 3570k is already flagged for a Ryzen replacement just waiting for DDR4 prices.

    Hopefully this won't kill my performance too much as I need this to last another year at least.

    Doesn't feel like a good time to be a PC owner but as I use it for productivity I have no other choice.

    so consumers need a 30% refund from Intel strictly in Sterling Pounds.

    Perhaps they will give you a free Pentium, they might have a few that are hard to sell now

    I know the feeling. Sadly I probably need to wait longer too - I was considering getting a cheap i7 for my board to keep me going before this news. Might as well not bother now...

    Yeah I nearly pulled the trigger on a top end IVB Xeon which was going for a decent price, so I also know the feeling.

    Re: Intel processor security flaw requires OS kernel level fix

    Notice how the news creeps out after Black Friday, Xmas and Boxing day sales, pretty cynical... With Ryzen now a viable alternative on both mobile and desktop, I think I'll stick to AMD.

    If everybody takes the same approach then the prices of i7 / Xeons from the last few generations could tank pretty hard. If your usage doesn't happen to be hit too badly by the issue then this could end up being a win. Not sure how long it will take for the 2nd hand market to adjust though, probably have to wait for the Zen+ launch at least...

    Re: Intel processor security flaw requires OS kernel level fix

    Maybe this is the true reason Intel pushed out so many CPU's this year. If this flaw had come out before the release of the latest series then they pretty much would have had to pull and redesign it.
