AMD's upcoming Vermeer CPU to be made on TSMC 5nm+ and not 7nm?

Rumors are spreading that AMD's upcoming "Vermeer" Ryzen 4000 series desktop processors will not be made on TSMC's 7nm process. Official roadmaps from AMD, which were published earlier this year, showed these Zen 3-based chips will be made on a 7nm process but word on the street is that AMD may have switched to TSMC's 5nm+ instead.

Taiwanese tech site DigiTimes talks about a readjustment of AMD's and TSMC's foundry blueprints:

Rumor has it that AMD and TSMC have adjusted their foundry blueprints. The Ryzen 4000 desktop processor series originally expected to launch at the end of 2020 will now use TSMC’s enhanced 5nm processor (5nm Plus) instead of 7nm EUV.

TSMC's 5nm+ is expected to enter mass production in Q4 2020. AMD's Ryzen 4000 series was scheduled for September/October so if this news is accurate it may mean that "Vermeer" will launch later than expected. This would explain why AMD is launching a "Matisse Refresh" in June. If AMD is indeed using 5nm+ for Vermeer, it could indicate a Q1 2021 launch date instead.
