Used in smartphones and tablets, based around ARM processor

Lower energy requirements and can go into “sleep mode” when not actively processing

Multiple machine cycles per instruction 

Greater energy consumption

Smaller in size as less complex circuitry required, less silicon needed to make thus cheaper

More intensive tasks will do better with CISC

Used in laptops and desktop computers, made by Intel or AMD

Run at lower clock speed, but can perform simpler tasks more quickly than CISC

Has more complex hardware

Can support pipelining

Has simpler hardware

Cannot support pipelining

Uniform instruction format, using a single word with the opcode in the same bit positions in every instruction = easier decoding.

Different sized registers = more complex compiler design.

Full range of addressing modes = easier ways of addressing blocks of memory.

Same sized registers, allowing any register to be used in any context with separate floating point registers = simpler compiler design.

Simple addressing modes.  Sequences of load-store and arithmetic operations needed.
