This discussion about RISC vs CISC seems to conclude that a RISC
machine by reducing the instruction set can run these instructions
much faster but won't reducing the instruction set increase the
number of instructions required to perform a specific task.

If the RISC instructions are twice as fast but require twice as
many, what is gained?

I know that in the real-world RISC-based machines are faster but
why?

yours ponderingly,
