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.


It's public now. It's even available as javascript.

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.


MS is focused on Windows 10 and has issued a patch for it, I cannot
confirm patches have been issued for prior versions at this point.
Unless the description for what you installed specifically states
it's for this issue, I wouldn't assume that it is.
