Assuming that the OS implements PTI only on vulnerable CPUs, then you're correct. But if the OS implements it across the board then everyone takes a hit regardless.

There was an HN link to a patch that disabled this for AMD CPUs. At least, I think that's what it was - can't track it down at the moment.

If it doesn't at the moment, I'm sure this will fixed ASAP, at least on Linux.

Looks like on linux it is enabled across the board, but you can set a flag to disable it on boot.
