Yes. I expect both vendors to reach parity with respect to mitigations of known speculative execution vulnerabilities. Whether their architectures have been fundamentally redesigned to make these issues more difficult to exploit is anyone's guess.

Variant 1: Both AMD and Intel will continue to rely on OS patches.

Variant 2: Both AMD and Intel will fix in silicon. Intel's fix comes in Cascade Lake.

Variant 3 (aka Meltdown): AMD was not affected, Intel will fix it in silicon in Coffee Lake Refresh and Cascade Lake.

Variant 4: Both AMD and Intel will rely on OS and Microcode patches

L1TF: AMD was not affected, Intel will fix in silicon in Coffee Lake Refresh and Cascade Lake.

I'll note that for the AMD products, this is my best guess from Lisa Su's comments. I do wish they put out a table like Intel did.

EDIT: Replaced the Intel source with a better link

Don't forget the recent seven additions to meltdown/spectre. It'll be interesting to see if the latest round of hardware protections help there.

8th gen (Coffee Lake) have the same uarch as Skylake and have no hardware fixes for Meltdown or Spectre.

Yes, but 9th gen has fixes: https://www.anandtech.com/show/13400/intel-9th-gen-core-i9-9...

And no pcie4 either, unfortunately.

Sure they take care of it real well... in the OS.. can’t wait till this comes to windows by default.
