I was wondering why AMD didn't finally get access to the top notch process at TSMC. They can have some of the best margins in their products, just because they ended being the best now and they certainly have the volume already. They didn't even start addressing notebooks or the lower ends of the market with Zen 3.
Zen 3 is probably the fastest CPU on the market, it is not even scaled down to N5 or N6 which could get power consumption down to the best we have seen for notebook market.
Instead the rumors are that in 2022 the improvements will go mostly into packaging extra cache. And now the next processes are already booked by others.
