Intel released CPU microcode updates to address four new security vulnerabilities disclosed by the company on May 14, 2019. These microcode updates can be encapsulated as motherboard UEFI firmware updates, and for some processors even distributed through Windows Update. In its Microcode Revision Guidance document put out on Tuesday, Intel revealed that all Core and Xeon processors going as far as the 2nd generation Core "Sandy Bridge" architecture are eligible for microcode updates. 

Specs: AMD 2920X Threadripper, Corsair MP510 M.2, 64GB Corsair RGB Dominator,  ASRock X399 Taichi, Corsair 1000D, EVGA RTX 2080 Black

    Chipmakers are going to be forced to do away with speculative execution altogether. Intel uses SpecEx to a far greater degree than AMD. Hence: ZombieLoad.

    Too clever by half.

    I’m assuming you’ve heard the expression before, lol.

    Intel makes more sophisticated processors, they run faster... they are also more vulnerable to side-channel attacks. Yes side channel attacks are very difficult to implement - but they can happen. If you can be hacked without even opening a file or some other security flaw you, the user, opened up - that’s a very BAD thing. You literally are powerless... as are antivirus software.

    They will run about as fast as their AMD equivalents (per core) and cost 60% more

    I'm not a programmer and know nothing about how a CPU is made and how it works. Though, I wonder:

    - why the CPU technologies onboard can't only work from itself out and not the other way around

    - why there isn't a DEP for processors onboard, and not just for the OS

    Will this be another performance hit?  This could be a slippery slope for them since this could be lawsuits in the making since these security patches are downgrading the performance from it's originality.  Granted software can bog down the system but coming from intel who is in charge of said performance guarantee out of the box and say barely any software installed, the CPU performance already takes a hit. 
     
    If it's advertised as a 4.0 Ghz CPU but say add 20-30% performance degredation, does it still stay the same speed but runs slower or is it actually running like and changed to a 3.7 Ghz CPU?  I'm not an expert hence my off shoot theoretical scenario but curious what some members who have knowledge in all of this have to say.

    Way over my head - although someone I work with put it this way - the more “chatty” a processor is outside of the physical core (with the chipset and devices, using hyperthreading, using cache to speculatively execute) the more likely those comms are to be intercepted. Practically all of the tricks that make modern processors perform beyond their physical limits on their own make them more vulnerable.

    It is reported:
     
    Intel offered to pay the researchers a USD $40,000 "reward" to allegedly get them to downplay the severity of the vulnerability, and backed their offer with an additional $80,000. The team politely refused both offers.

    Because of the current (implemented) design --> The OS & CPU have a direct connection for Speed. 

    New designs would have to include more hardware inside the CPU

    If they weren't so greedy and attached a few more zeroes to the bribery figure it may have worked.

    I'm a Intel guy just like an Nvidia guy.  Not going to lie about that but will criticize where it's do.  With that said, these tactics I've noticed for some time now aren't just bad PR but very troubling.    Some theories come to mind.  They're innovationally weak and in trouble and know they're going to hit a ditch soon (think AMD for the last several years) and these shiesty tactics are a way to make the public/shareholders think otherword.  If I was a intel shareholder atm, I'd be worried if they haven't been already.
     
    For the record, I still hope they come out with a slam dunk CPU soon so I can upgrade and have a playable experience in BFV.

    I’ve just rewarded Intel $1,400 for their incompetence and venality.

    Bought 9940x which is supposedly unaffected by ZombieLoad (which is apparently far more serious than what we’ve been led to believe). Although part of me very much wanted to pull the trigger with a new AMD build - like most I’m too heavily invested. Vmware offers no assurances as to the compatibility of their workstation suite with thread ripper - and learning the ins and out of new hardware is just not in the cards.

    I’m looking forward to others taking the plunge first and ploughing the way forward to getting off of Intel’s hamster wheel..

    I used to mine. Now I compute.

    Meanwhile things look pretty good for AMD right now.
    Granted it was vulnerable to meltdown but not as direct as intel.
    But yeah intel was hit hard by spectre and meltdown and now this.
    Will AMD face a similar issue? Perhaps but it does feel good to be on team red where my processor is concerned right now.... intel is taking a beating by these kind things

    I’m gonna put on my tinfoil hat and suggest that a lot of these “flaws” were by design and intentional - and were put there to aid and abet eavesdropping.

    Only after outside researchers caught them did they patch these “flaws”.

    I used to mine. Now I compute.

    I wouldn't go that far it's entirely possible that Intel probably had no idea that this sort of thing was possible and if they did they may not have known the whole effect of such things. After all nobody has a crystal ball and no one can see into the future and how technology can have issues later on the pipeline.
