    Well, we know that Intel says Intel and ARM processors are open to these attacks. And we know AMD is almost certainly not. Read up, buttercup.

    Check out the video in action.


    Am I affected by the bug?
    Most certainly, yes.

    Can I detect if someone has exploited Meltdown or Spectre against me?
    Probably not. The exploitation does not leave any traces in traditional log files.

    Can my antivirus detect or block this attack?
    While possible in theory, this is unlikely in practice.


    And that's the good news!

    Edit: Direct from AMD -

    So when is the class action lawsuit that gives everyone $30 off towards their next Intel CPU?

    When the price of each intel CPU raises by $50.

    Already have my receipts ready!

    Their statements do seem to suggest though that Spectre should affect AMD processors, its just they haven't been able to reproduce the attack on AMD processors. Meltdown apparently is Intel only successfully verified.

    Spectre is variant 1 and variant 2. Variant 1 affects AMD Pro and FX CPUs under Linux and is patched. Variant 2 affects Intel only with near zero risk to AMD due to architecture differences and there is no known fix.

    I have 5 receipts for Intel CPUs I've purchased over the past decade. Can't wait to get my $50!

    lol, thanks for pointing out the different variations variant.


    That just shows you how long they are sitting on this, probably spent a good couple weeks sampling logos for the website.

    Intel already took a nice hit in the stock market due to this, so their statement is seems to me that it is meant to spread damage to AMD.

    Started digging into those myself and them implications look to be profound especially when it comes to CPU optimization techniques which are at the crux of these particular issues.

    Going to be funny when IO operations are faster on a Core 2 than an i7....

    The patch hits ALL Intel x86 CPUs, so it's more likely that the Athlon 64 X2 will be faster in I/O.

    While Intel would love to serve us a few processors in the home, Intel knows the real profit is in servers. Intel runs the vast majority of the 75,000,000+ servers out there. And those are just internet servers, not SQL servers, or file servers.

    But it's not like servers would do a lot of kernel IO now would it?....Oh wait.

    Now show me some server benchmarks


    Now lets say the slow down is a rough 20% when there's a lot of IO. That is about 15 MILLION CPUs Intel has to come up with quick, preferably with the fix installed. Last I checked Ice Lake was behind schedule.

    So who's the viable alternative?

    Since your post only shows gaming benchmarks, it's misleading. It's not the whole picture.

    I have an intel CPU, but I am not wholly upset with intel, I would not be heart broken if they made exploiting a capital offense, they ruin your cpu's, they ruin your games, they ruin your privacy, they ruin your safety, just wait until things become more automated and they ruin you living.

    For my home gaming PC, I don't expect too much difference in performance. At work, I am very concerned for our VM Ware environment as 90% of all our applications and software is virtualized and will be impacted severely. We could find our entire network infrastructure lose up to half its performance from this.

    I like how the mufuka that be the intel ceo, keeps this bullshit quiet just long enough for him to dump his millions of bucks of shares before news leaked out and intel share value fell.

    What a cnut.

    See I didn't buy an AMD CPU because I was poor, I've been preparing for this for years due to being clairvoyant :)

    Have to see when the fix is in play from Microsoft to see what the real damage is, googling around it's 30% up to 49%, what next, 145%, you apply the patch and all devices near your pc get slower?

    "Hello support, my blu ray player is loading slow... It it sitting near an intel PC?"

    I dunno what's worse at the moment, owning an intel cpu or being intel.

    Thanks to this Azure started rebooting our VMs a week early with very little notice once Intel et al. lifted the NDA. Not really a problem but not fun either way.

    Ok maybe I'm not understanding this. But it looks to me like 1) someone has to get a malicious program running on my system; 2) has use this exploit to get a memory dumb; 3) has to somehow get that memory dump transmitted to them and 4) has to comb through to see if they got lucky to get a password (and know what that password applies to) or CC#. I'm not losing much sleep over this (but I'm not running a server for say Amazon I'm only talking about my home PC). And a program to do 1-3 seems like that's going to have a signature once known and can be virus scanned.


    And for speed. This mostly is on I/O. I/O that's cached and can be predicted is that correct? So my most I/O intensive task is doing a make on a large project. But it's just reading straight from the SSD and then writing the complied code back to the SSD, so this isn't likely to be effected by the patch if I understand what's going on.

    Wow....AMD on the ball! AMD has a golden chance now to get some market share back on the Enterprise side.

    AMD marketing will find a way to let this golden opportunity slip through it's fingers.
