The difference between an IGP and a discrete option is more than just clock speed. A big part of the difference is fast dedicated memory (GDDR or HBM2), a solid cooling solution, and more importantly the amount and type of cores. Apple has never had great cooling in their machines, save for the big G series towers and the Mac Pro, so some performance is lost right from the get go.

Apple is likely to go their own way, for better or for worse. We knew this when Metal came out and they started to move away from drivers universally used by industry (OpenGL). That’s fine, people don’t buy Macs for graphically heavy weight stuff like 3D simulations or gaming. Most Mac users want the GPU for compute power for video rendering, and such, which is why going with AMD/ATI has long been a staple of the Mac.
