You need a discrete video card on ARM exactly as much as you do on x86.
The GPU is independent of the CPU architecture, so if you don’t like x86 iGPU performance expect to not like ARM iGPU performance either.
Of course you can dump a full desktop dGPU into the same package as your CPU, like Apple did with the M4 Max, but again this can be done on x86 as well. None of that is dependent on the ISA.
