I think *AMD's* stock is going to go up a lot more than Intel's, because = they have pretty good server/workstation hardware now, and no = vulnerability to the most serious variants of this attack (which means = no performance impact from mitigation). Apparently there are also = mitigations for Spectre v1 and v2 which have minimal performance impact; = Meltdown is the one which has a big performance cost to deal with. Probably some ARM and PowerPC server vendors could get a boost too, but = only after their exposure to these attacks has been properly assessed. - Jonathan Morton
