On Meltdown AMD claims "Zero AMD vulnerability due to AMD architecture differences.".

ARM has handled this best (Meltdown is Variant 3) https://developer.arm.com/support/security-update

I just finished watching a webcast on sans.org regarding this. A recording of the webcast should be available on their site later today (4 January). Some of the things I learned: 1. The 'Meltdown' security flaw is present in intel, AMD and ARM processors and relates to out-of-order instruciton execution. 2. 'Meltdown' exploits have been developed by researchers using intel processors but not on AMD or ARM processors.  However, the latter use similar out-or-order execution/cache strategies and are, in theory, subject to the same problem.  The speaker indicated an exploit on AMD and ARM processor was 'only a matter of time.' 3. The Sky is Not Falling. Or was that a piece of sky that just landed on my head? ss/wb

Disaster?  Not at all.  Let me know what you want for all your 'shelf warmers'.

...for the computer industry, this is a disaster. Computers with faulty processors now become shelfwarmers or have to be sold very cheaply. I have already postponed my intention to buy me a new notebook.

AMD's CPUs aren't vulnerable to the issue, so Intel has to do everything they can to make people think "everyone is vulnerable" so server buyers don't choose AMD models instead of waiting months for Intel to have fixed CPUs available that won't suffer from the performance degradation.

AMD is Intel's only meaningful competition, so of course they want to leave people the false impression that AMD is vulnerable. Other processors are vulnerable (apparently ARM designed cores are, not clear if independently designed ARM cores by Apple, Samsung, etc. are or not) but they don't compete with Intel at all.

Does anyone have more specific information on this hardware bug?
