The performance of a RISC processor depends on the code that is being executed. The processor spends much time waiting for first instruction result before it proceeds with next subsequent instruction, when a compiler makes a poor job of scheduling instruction execution.

RISC processors require very fast memory systems to feed various instructions. Typically, a large memory cache is provided on the chip in most RISC based systems.
