The Answer is There are number of reasons for the move towards RISC machines away from CISC. Some of them are:

\bullet

Since early computers had limited memory capacities and were expensive, having a CISC instruction set enabled performing complex operations with very few instructions (encoded within a smaller memory size compared to a corresponding RISC program). Since then memories have got cheaper and there has been a lot of advances in the design of cache hierarchies (for example, a dedicated on-chip instruction cache, prefetching techniques, etc.) that permit RISC machines work-around longer instruction sequences

\bullet

Writing a compiler to generate efficient code is easier for a RISC architecture than for a CISC architecture as the compiler can take advantage of a lot of registers provided by the RISC architecture than a CISC

\bullet

RISC instructions are easier to pipeline than CISC instructions
