There is apparently a security flaw in every recent Intel microprocessor, and by "recent" I mean "since November 1995".
Ryzen CPUs (and maybe AMD processors in general) appear to not be affected.
This one looks nasty--it looks like speculatively-executed instructions don't get security checks. Someone on Twitter claims to have an exploit that lets them read kernel memory.

(a) Make heavy use of virtual machines
(b) Do heavy random I/O - databases are about the only thing that really does this.
Games are about 1% slower. Most desktop apps will be affected even less than that.
Cloud servers are badly affected. One multi-user game went offline when Amazon patch their servers because the load basically doubled for the same number of players.
I do know one developer who returned his brand new Intel 8700K system and replaced it with a cheaper AMD Ryzen 1700 machine (which is what I have) and got much better performance. (AMD isn't affected by Meltdown, and is partly safe from the other bug, Spectre.)

Yeah, since that's my day job, I'm looking forward to that.

Will get both fixed ASAP.
