> The underlying vulnerability is primarily caused by CPU architecture design choices. Fully removing the vulnerability requires replacing vulnerable CPU hardware.

Me: So I guess we have no choice but to upgrade all our x86 to AMD.

just read a few articles/papers about the intel bugs #meltdown and #spectre.
#meltdown require OS kernel patch, cause 5% to 30% slow down for system call intensive apps (networking/file). and #spectre is unfixable.
We are fucked. by next week, nobody will remember the problems, except hackers and gov. But have a cookie, you are fucked already anyway with ur phone and usb and ssh etc.

- Patron, on va arriver à saturation des ventes de CPU, l'obsolescence programmée ne suffit pas à relancer les dites ventes et à renouveler le parc
- Ok, on va mettre une grosse faille qui oblige à vraiment remplacer le truc discrétos, et dans 10 ans on révèle le machin, et hop, vente forcée sans rien faire

Seul #Spectre touche #AMD.
