Or those who play on recent handhelds. Steamdeck with integrated RDNA2 is very capable with even modern games. Sure, you can't crank it up to ultimate quality with hundreds of fps - but it's enough, and above the "cheap" level of performance.
Also, looking at geekbench results, it basically matches the M2 Max in a mbp.
Currently the most powerful AMD iGPU is Radeon 780M (found 7840U/HS and 8700G CPUs). Judging by Notebookcheck‘s results, M2 Max GPU has up 2× the fps in Borderlands, 2.5× the fps in Witcher 3, and 3× the fps in Shadow of The Tomb Raider.
As for the benchmarks, the M2 Max GPU has 4–6× the fps in GFXBench, compared to Radeon 780M. And the RDNA3-based 780M has twice the raw compute performance, compared to Steam Deck’s RDNA2 GPU.
Unfortunately, GPUs in handhelds are always severely underpowered.
I wish Asahi would move forward much faster and I could game on it, but at this point, gaming on a Mac isn't really a thing.
Source: I have one from work that I really want to be able to play. Whisky, Crossover, Parallels, I tried them all.
M2 Max isn't available on the free market (as part) but if it where it likely alone would cost noticable more then what a full handheld can afford to cost
With a caveat: at its native 1280×800 resolution.
