Stunning. As someone else mentioned the electricity hit alone could be
enormous. Not just in data centres but across all intel users.

Class action suit against intel I think. This is on the level of the
FDIV bug of yore. Worse in some sense.

Must be full cigar time at AMD...

Curiously Apple claim that their mitigation of this has no measurable
effect on one aspect (CVE-2017-5754 or "rogue data cache load" - aka
Meltdown) of the flaw (using 3rd party benchmarking s/w); and "only"
2.5% slowdown in one of three benchmarks for the other flaws (
CVE-2017-5753 or "bounds check bypass," and CVE-2017-5715 or "branch
target injection.").

This makes me wonder if the article's claims of 5 - 30% slowdown (post
OS fix [Windows, Linux]) are exaggerated or if Apple's fix is either
miraculous or incomplete.
