Yes. TSMC figures will be optimistic/best case - so that 55% increase drops to ? 45% ?TSMC data is in theory... AMD reached around 40% increase avg. in real benchs with Vega 20 going from 16nm to 7nm.
There is obvious some Architecture improvement with Navi but it is way lower than the marketing tries to show.... 10% improvement in perf./watt with a new Arch is good it is just not Maxwell level.
(the table you posted above) - I guess the comparison is VegaVII 16GB vs Vega64 8GB .. but here's the thing - there's also a doubling of HBM2 memory in that comparison which adds further power consumption to VegaVI, making the gains less by an (unknown) amount ..
I hope that +50% is purely architectural otherwise the non-shrink gains seem to be approaching negible levels ..
