> Did processor companies ever advertise that processors guaranteed certain security properties
It's not the guaranteed security as much as the advertised speed that's the issue. If they put out a chip which could only be used at half the advertised speed or else it would catch on fire, nobody would argue that they should be let off the hook because they didn't guarantee that the chips were fireproof in their ads.
If the chips can't perform at advertised speeds safely during typical use they're not delivering what was advertised.
