I'm curious about AMD not being vulnerable, mostly because this page: https://www.kb.cert.org/vuls/id/584653 makes me think that AMD has admitted to being vulnerable.
That page talks about both Meltdown and Spectre, as far as I can tell. AMD is vulnerable to Spectre; everyone agrees on that. According to https://www.amd.com/en/corporate/speculative-execution AMD claims it's not vulnerable to Meltdown (aka "Variant Three").
