I'm guessing some might roll their eyes, but I am trying to decide if I should wait until April to buy my new AMD Ryzen 5. Will newly manufactured 1st generation Ryzen 5 CPUs incorporate the necessary changes? And how about 2nd generation Ryzen, will it have these issues and need microcode updates or will these security issues be addressed at the factory printing of the CPUs? I would rather use CPUs that don't have the issue, versus ones that reply on microcode update with every boot.
 
I think (but do not know) that permanent microcode updates for any processor will only happen when then vendor release a new revision of that processor. If I am right, I also think that a new revision (which also includes other changes, not only microcode) will take longer time than until April this year.

Well 2nd generation Ryzen is coming, and AMD has known about this issue for a while, so I logically think that they would have made those changes already, before they start mass manufacturing in March / April. Wish there was a way to confirm.
 
how do I know if a microcode update like happened?

I notice it says intel......so are amd64 not affected?
