    Finally, a compelling reason to go with AMD.

    Everything, through Linux, OSX and Windows will have to software patch an easily exploitable hole in the Intel CPU architecture. MS will be pushing an update next week, linux distros are all patching ASAP and Apple is dragging it's feet.

    https://www.theregister.co.uk/2018/01/02/intel_cpu_design_flaw/

    So there we go. Fuck.

    Should be noted it's just the CPUs, not SSDs or t-shirts or anything.

    I love the line from the AMD guy in that article that gives the game away.

    My entire work computer estate is on Intel processors (hundreds of thousands of machines). Yes, it'll be bad for gamers and power users, but these kinds of numbers could be bloody awful for business.

    Edit: okay, maybe not so bad for games and such, but the rest...

    Oh fuck indeed. I've just read it's an architecture problem and the patch will just block the exploit but permanently cripple all CPUs made within the last decade.

    This is big and bad; I think we might have the biggest tech story of 2018 right here. What will really light a fire under this as far as the media is concerned is that Intel's CEO sold a hell of a lot of stock in the company just a couple of weeks ago, at a point at which this was likely known internally but not yet public.

    From what I've managed to read, impacts on users will vary depending on what their system is used for. Gaming is not likely to be as heavily impacted as other uses.

    But this is about as bad for Intel as it could possibly get.

    It’s genius by Intel. Suddenly all of us hanging in with Haswell or even older CPUs are forced to upgrade to maintain the same gaming performance we’ve been enjoying for years

    @THFourteen Yeah, except in all likelihood, chips coming off the production lines today contain the flaw. "Fixed" chips may still be weeks or even months from market.

    Plus the potential for class action suits here is immense. There is absolutely no upside for Intel in this.

    2018 starting out to be a bumper year full of great news.

    @Rogueywon

    Looks like us gamers will probably be Ok

    @THFourteen Indeed, though gaming isn't the only thing I use my PC for. But I note those benchmarks are all Linux-based, where kernel patches already exist. A lot of the actual real-world impact is likely to come down to how MS choose to address this via their Windows update, as that's more relevant for the majority of gamers.

    They'll find a way to keep the cripple to a minimum, it's as much in their interest as it is Intel's to fix the issue in CPUs going forward.

    I'm sure we'll see a lot of benchmarks, but considering that most games are already inefficient at using the CPU's full potential, it probably won't make a difference either way.

    I guess it will be much more annoying for servers and for productivity applications in general.

    As the ancient i5-750 on my dying mobo is already close to collapse under any more or less recent game, it's not great news for me. Also not because I hoped to buy an i5-8400 in the near future. Maybe I'll delay/reconsider that.

    Fuck's sake. Bought a fancy-ish laptop last year and now I'll resent it.

    I imagine if not already in production, revised models wont be far off. So best to wait for the all clear.

    I feel like there's a possibility this will be easily patched with minimal impact, but there's always that big grey area of doubt. Just going to bite my nails until the patch drops and the benchmarks roll in.

    Yeah, we had a meeting about it yesterday. Quite apart from the capacity planning of potentially taking such a massive performance hit, having the kernel memory readable on servers performing financial transactions isn’t exactly ideal.

    Thankfully, that seems like a pretty clear case of insider trading, so Kzranich should get jail time rather than a shrug of the shoulders, a mea culpa and a golden severance package.

    It should be fairly easily patched but some people who have a syscall intensive workflow will need to buy a new PC/Server/Whatever. As far as I can see, there’s no way to patch this without a substantial overhead cost.

    I'm not going to hold my breath on that one, past experiences has taught me that rich white guys get away with a lot.

    If it was murder, possibly but the yanks really don’t like people fucking with capitalism.

    @JamboWayOh Even if that's true, what will count against him in this case will be that a lot of the people screaming for his head will be even richer white guys (Intel shareholders, plus those of all of Intel's major business and Government customers, all of whom are going to get hit by this).

    They'll have to redesign their chips though, adjust the production process, retrain the Chinese children who solder the nano-circuits together and stuff. I'm no expert, but I don't have the feeling the new chips will be on the market in a few weeks. We'll see. I was considering AMD alternatives already, the i5-8400 just seemed to have a particularly attractive performance/price ratio right now.

    He must be fairly confident he can get away with it. He must have known when he did it people would notice as soon as this shit storm hit.

    @DrStrangelove While we're all just finding out about this now there is no way Intel haven't known about it for a while. It would be suicide to still be producing chips with the flaw now. However if if it does take longer is it really worth knowingly buying a flawed design rather than wait? Even if it was fast enough for what I needed I wouldn't buy one of the effected chips on principle now.

    Yeah, that would be me. The hassle this could cause is mind numbing right now, I just don't want to have to deal with it.

    I would imagine that the percentage of companies and governments that this will effect will be in the high 90s.

    AWS powers half the internet and Azure takes care of the rest of it. Amazon must be losing their minds.
