Difference between RISC AND CISC Architecture

The major difference between RISC and CISC Architecture are as follows :

RISC CISC
It contains small set of instructions with fixed format.It contains large set of instructions with variable formats.
The Data transfer is from RISC is from Register to Register.The Data transfer in CISC is from memory to memory.
The CPU control in RISC processor is mostly hardwired without control memory.The CPU control in CISC processor is Microprogrammed contorl unit.
RISC has low cycles per second.CISC has high cycles per second.
In RISC, instructions are reduced and simple.In CISC, instructuions are complex.
RISC contains Register based instructions.CISC does not contains register based instructions.
RISC includes single clock.CISC includes multi-clocks.
