Not being good at 3D already means it's bad.
Adobe Photoshop and Lightroom is such a poor example as they take advantage from high clock CPU speed, not GPU performance which is not even GPU intensive software. If anyone testing Apple GPU with 2D based on not GPU intensive software, then they have no idea what they are doing. Seriously, you only tested in too specific area where GPU doesn't really matter. Why do you even limit the test result with Adobe Photoshop, Lightroom, DXO, and Topaz? Those results dont represent the performance toward 3D at all.
All you doing is justifying its performance based on 2D fields, not 3D fields which is way more GPU intensive. Is it a joke or what? What you are claiming its that Apple GPU is good with none GPU intensive software. So how about game, graphic, AI, and more? Apple didnt even invest any of them.
If you really wanna check Apple GPU's performance, I would highly suggest to test them with GPU intensive software but then, Apple Silicon Mac does NOT have or support GPU intensive software which already defeats its purpose. This is why Mac is only well known for 2D or none GPU intensive software.
If you still want some real life test, Resident evil 8 is a great example: M1 Max is not even close to mobile RTX 3070.
