Yes, but they are RISC architecture rather than CISC.

Reduced Instruction Set Computer chips have few built in commands, and achieve complex instructions by chaining together lots of simple ones.

They run much faster than Complex Instruction Set Computers. Hence, even though an old PowerPC chip might have a clock speed of, say, 800Mhz... it's still much faster than a 2GHz Intel.
