For a few seconds I thought you were all talking about back when Intel introduced thermal management causing AMD to get a reputation for burning up[1] if the heat sink wasn't properly installed.
The issue with Spectre is that it is a new "buffer overflow". You can't "fix" a buffer overflow through hardware alone. You need software + hardware... and at best, you only get mitigations.
And within the next few months, some researcher is going to come up with a new Spectre-based attack that current mitigations won't work on. Its a bit annoying. Just sit tight and stay up to date on Spectre, its a moving target.
Not that I'm aware of, but neither has Intel. Intel recently published some patches that will enable Enhanced IBRS mode in future processors but those haven't even been talked about yet, I imagine that AMD will do something similar in the end but we haven't heard it yet.
