The article I read said AMD is not affected.
The proof of concept may be awhile. Apparently
they're being deliberately vague to avoid giving
away the bug until it's patched. (Also see article.)



I think I was muddling two separate vulnerabilities which seem to be
called meltdown and spectre. Meltdown affects only (or maybe mainly)
Intel. Probably Meltdown does have proof of concept code somewhere but
hopefully not public.

I just installed a large security patch KB4056894 on both my Windows 7
64 bit PCs which apparently includes patches for something or some
things that are important, probably including Meltdown. No noticeable
slowdown seen yet. Benchmarks: the one in CPU-Z still the same result,
Novabench 4.0.3 still same result.

Looks hopeful.
