Hmmm not sure I agree. You say useless but we've seen that when a well optimised game is released (RE Village) the max does match a 3080. No credible test I've seen says the 3060 matches the max in raster performance.
MacStories agrees on real Mac Studio hardware. 3080 desktop he mentioned is actually faster since he compared it to 120fps which is Max graphics preset and Ray Tracing enabled. Max graphics without Ray Tracing is 169fps so with the lower Prioritize Graphics preset it's even faster.
I ran REV on mobile 3060 at same 2560x1440 Prioritize Graphics preset and averaged in the 120s fps. Here's baby crib scene for reference.

I started the game on my M1 Max Mac Studio and Studio Display at 2560 x 1440 with the game’s Prioritize Graphics preset enabled. At those settings, Village generally maintained 60-70 fps with a rare dip into the 50s during one particularly intense scene.
The results aren’t in the same league as a gaming PC with a dedicated graphics card. For example, I’ve seen benchmarks for Resident Evil Village running with an NVIDIA 3080 card that can run the game at over 120 fps. That’s double what I saw with my Mac Studio...
