Everyone talking like games are the only thing these bombastic chips can't do.
Well there are many other things they can't do either, like CUDA acceleration (for many python-based ML and DL algorithms), or any kind of workflow relying on OpenGL in general.
Sure there are workarounds, but Apple made it clear they do not intend to push other platforms then theirs by putting hardware acceleration for ProRes in their chips, and showing off apps like Compressor, Logic and Final Cut.
Nothing wrong with that, classic Apple, it just means it's a platform designed for SOME pros, not ALL pros.
I do image analysis and frequently hit some issues due to Apple's lack of support for tools commonly used otherwise, and that's why my main machines remain PCs. Ironically, this forces me to be in the Microsoft ecosystem a lot, and the Macbooks are still very enjoyable for classic desktop work.
Now, that being said, if Apple was really serious about gaming, they would create a separate line dedicated to that. I would see them buying Razer like they did with Beats, and keeping the brand while using Apple chips and a custom OS that supports all the nice libraries, like SteamOS does.
Sadly, they will never do it, either to avoid spreading their line too wide (to remain faithful to the famous Steve Jobs 4 quadrants), or simply because they just don't get it (Apple Arcade is becoming a sad excuse for the mess they brought to this world with their app store policies).
