However, only one of the PoCs runs on AMD, and that doesn't cross process boundaries.

So how easy is it to turn that PoC into something I should worry about? Seems like browsers are the most affected by this scenario, but that also means harden the browser (separate process per page) and it might be difficult to exploit.

As a general rule of thumb, if everyone already has a PoC, you should assume someone has been doing targeted practical attacks for a while.
