I'm pondering about building CPU from logic gate chips. The thing is most projects like that use chip count efficient (usually microcoded) designs which aren't fast enough to run "real" familiar software. I want 32-bit instruction set with virtual memory, capable of running Linux and fast enough to run games like Doom. Fastest reasonably available logic gate family is 74AUC (possibly with exception of exotic ECL gate…

I imagine the physical factors like capacitance, induction, impedance etc will be the limiting factor
