    Well AMD the performance king now it seems. :)

    "Millions of computers using Intel chips are prone to hacking thanks to a flaw that went unnoticed for a decade, it has emerged.

    Software giants are currently working on a fix for that flaw but industry experts have warned it could potentially slow down all devices running the chips by up to 30 per cent.

    The flaw could allow hackers a ""persistent and undetectable backdoor into someone's computer," Mike Godfrey, cyber expert at Insinia Security told the Telegraph. "

    Is that the end of Intel? 10 years, damn.

    The 5%-30% seems to have been from a Linux test.

    Wow, not good at all. I wonder how long it will be for a patch. I run script blocking addons on my browser so hopefully I haven't been infected.

    https://www.google.com/amp/s/www.bl...ter-rival-intel-said-to-reveal-processor-flaw

    On Tuesday, the technology website The Register said a bug lets some software gain access to parts of a computer’s memory that are set aside to protect things like passwords. All computers with Intel chips from the past 10 years appear to be affected, the report said, and patches to Microsoft Corp.’s Windows and Apple Inc.’s OS X operating systems will be required. The security updates may slow down older machinery by as much as 30 percent, according to The Register.

    It appears ARM is affected as well

    From the link above.

    OC3D has some Linux graphs

    Little effect on gaming. The difference in Assassin's Creed: Origins was 126 FPS to 123 with an i7 7700K.

    Ryzen tests here, and yes there is a difference. From what I can tell, I might be wrong, but all 3 are being affected by the bug but only Intel stuff is vulnerable.


    The Linux gods are still treating AMD stuff as vulnerable.

    It appears there has been 2 vulnurabilities, Meltdown which only affects Intel and Spectre which affects all 3.

    Seen some stuff from windows 10 only

    I cant link them cause it was a post on reddit that I can no longer find but it looks like it doesn't affect gaming on windows 10 if thats what you are worried about

    Also from what I know the patch for Windows 10 is available now and 8.1 and 7 will get patches in the next week or so

    Yeah that thread got deleted on the PC Master Race Reddit for some reason. Here's a European site with some benchmarks showing basically no difference.

    Well it's being reported the fix may not resolve all the problems for intel. No reports of impact on AMD other then continued reports of potential problems. ARM seems to be getting similar issues. The are reporting it as a performance shortcut in a Google testing report.

    "
    Variant 1 is software patchable and affects almost all modern processors, Variant 2 and 3 are not patchable and affect Intel and potentially ARM"

    And this was already the market that was really under threat from the release of Ryzen (the EPYC wing).

    This is a disaster for Intel. I'm surprised their stock didn't plunge more today.

    Mention Bitcoin in a tweet and you go 10% up.

    Admit that you just buttfucked your biggest customers over the last decade and that you may have crippled THEIR operations - 1% down. Analysts have no fucking idea what just happened.

    WTF happens when FB, Google or Amazon take a 30-50% hit on server speed? From what I understand networking is particularly hard hit. Compiling is fucked. Games - zero effect.

    Also seems AMD also shares issues though not so serious. ARM mobile doesn't have issues, big ARM has some issues.

    Nice write up:

    https://www.wired.com/story/critical-intel-flaw-breaks-basic-security-for-most-computers/

    "Although both attacks are based on the same general principle, Meltdown allows malicious programs to gain access to higher-privileged parts of a computer's memory, while Spectre steals data from the memory of other applications running on a machine. And while the researchers say that Meltdown is limited to Intel chips, they say that they've verified Spectre attacks on AMD and ARM processors, as well."
