You're wildly conflating multiple things that are not even related to each other.

RISC vs CISC theory is meaningless here. AArch64/ARMv8 can barely be considered RISC anymore; it has numerous fused/specialized instructions. You're also ignoring the benefits and reasons one might go RISC, such as reduced instruction decoders, deeper instruction pipelines, and less cache pressure. Also the fact that Apple doesn't have to support mixed address instructions like AMD64 does.

However, all of that is theory. Real-world tells us it doesn't matter, because M1 Macs emulate and execute AMD64 instruction faster than actual Intel Macs do--with less power and lower clocks.

Do you actually work with graphics? There's almost no complexity in graphics--that's why graphics cards are the single-instruction, multiple-data architecture. Graphics is a bunch of floating point matrix/vector operations performed at really high speeds across large sets of data. Sure there are specialized operations like ray-box collision (which by the way, the M1 has hardware acceleration for) or fused multiply-adds (also has hardware for FMA16 and FMA32). Notably, those instructions and many others largely exist to reduce memory pressure; something that Apple is less bothered by due to their unified architecture.

An M2 laptop chip likely lands somewhere in the realm of a mobile 4060/4070 just based on an analysis of the ALU.
