The data that you seek regarding the linearity (or lack of) for AMD's Renoir and Matisse (Zen 2) on TSMC's 7 nm is shown here:

If you just want to get an idea of monolithic APU performance as a function of processor U, H, and HS ratings as a function of power, see here: (note chose laptops that exhibited no thermal throttling from notebookcheck and ultrabookreview if I remember correctly):

TSMC's 7 nm process is highly tuned for lower powers. There is a rapid increase in power for minimal performance gains above 65 W. This is unlike Intel's '10 nm ESF' which is rather linear to 80-90W as shown by Techspot. Please note that I sent Techspot staff my analysis a while *before* they did their Tiger Lake analysis.
