Not true. Copy-pasting from my Ryzen terminal:

   $ spectre-meltdown-checker | grep "NOT VULNERABLE" | wc -l  
   12

So? The same script reports 11 lines on my 4 year old Haswell. It should read as "mitigated or not vulnerable" instead of simply "not vulnerable".

Edit: oh wait, it's actually 12 lines, the same as on your system. The reason it reported 11 on the first run is because KPTI has been disabled manually here.

:) I grepped for the wrong thing. Here's a better version:

   $ sudo spectre-meltdown-checker | grep "Not affected" | wc -l


   On Skylake: 0
   On Ryzen  : 10

I don't have an Ivy Bridge CPU to test this on, but AMD has suffered from _significantly_ fewer number of vulnerabilities than Intel, not just "one more" as the top commenter suggested.
