It isn't much of a sudden shrink.Without me being an expert in foundries/lithography, but AMD is launching Zen3 and RDNA2 next month, they are practically finished products based on 7nm (or +) node. There is no chance of sudden 'shrink' of those in few weeks.
N7+ was finished in mid-2018 at TSMC.
N5 was finished in early-2019 at TSMC.
N7+ at TSMC was getting a lot of flack as being bad. With most of customers cancelling their orders for N6 for non-cadence products and N5 for cadence products.
N7+ was projected to 100 million Taiwan dollars for it's volume production of 2019. For 2020, it was absorbed into N7 revenue which is shared between N7/N7+/N6. Which indicates they don't want to talk about it going forward.
N5 at TSMC was getting huge praises as being good. Being a very strong node for mobile and HPC.
Compared to above, N5 was projected for 10% of annual wafer revenue and 8% after COVID19.
Non-cadence = They switch to whatever node on their timetable.
Cadence = They switch when the foundry provides. (Two year cadence: 14nm/2016 -> 7nm/2018 -> 5nm/2020 -> 3nm/2022)
The general idea is AMD had two designs:
Zen3 on 7nm family nodes and Zen3 on 5nm family nodes. Which started development near each other.
As 7nm+ became more negative at TSMC, then the 5nm node getting praised at being ahead of schedule. The logical conclusion is to have the Zen3 on 5nm design to be preferred.
Zen3 on 7nm+ engagement in 2018. => Thursday, January 9, 2020 tapeout
Zen3 on 5nm engagement in 2018 => Sunday, August 4, 2019 tapeout
Third quarter 2018 => 7nm+ risk production
First quarter 2019 => 5nm risk production
