The small A53 core is pretty safe, but only because it's branch prediction is so simple there's just not enough there to leverage for a meaningful exploit. You're obviously not going to be running Doom Eternal a CPU with those.

Overall, IBM and AMD seem to have both been more careful about internal design decisions related to the core itself (with caveat following). My concerns with AMD continue to revolve around the black-box PSP, closed firmware, and NDA restricted documentation, none of which will help anyone trying to determine if shipping AMD CPUs are actually affected by these (or other) issues.
