From the Intel advisory:

This vulnerability does not exist on Intel-based consumer PCs.

I'm glad that credible sources are now available. It's unfortunate that it took so long to confirm, but congrats to SemiAccurate on a massive scoop.

Edit: On the previously-mentioned scale, this sounds like a solid 8 or 9 out of 10.
