For BOTW specifically you're better off playing on CEMU (Wii U emulator) as it's the exact same game(not a more limited version as one would assume) but significantly faster. TOTK you'll need RyujinX.

Exact numbers are hard to give: native game resolution or native macbook resolution? Docked or undocked? Shaders cached or not? Graphics mods (some of which are efficiency/performance related) or not? Generally though most games run at native size at native speeds once you get everything going. BOTW/TOTK are some of the heavier ones though and, ignoring BOTW as I play that on CEMU, TOTK runs alright as long as you don't push it or expect high FPS mods.
