Rumor is that Zen 3 will have 4-way SMT. I wonder how much this calculates into more IPC.

Rumour has it that SMT4 isn't planned for Zen 3[0]

Is SMT as unsafe on AMD as it is in Intel?

No, they properly checked so they were not as affected as Intel.

Meltdown didn't affect them at all and iirc they where only affected by one of the three spectre variants.
