So...after reading/watching some follow-up...
It looks like the card that AMD demoed when Zen3 was announced was the 6800XT which is the 72CU version of Big Navi 21.
Leaked Big Navi product stack shows an 80CU version.

Additionally, the TSMC process is showing it's benefits in the OC headroom on the Big Navi cards. AIB's are getting 2.5GHz on air.

All of this leads me to believe Ampere is not long for this world.
