RISC and CISC (continued...)

Advantages of RISC over CISC are their speed, smaller chip designs, less cost and can be designed more quickly.

Despite of RISC advantages, RISC was not adapted as processor developers were unable to manufacture RISC chips in large enough volumes to make their price competitive. Also, Intel is a big company using CISC chips. Intel spends lots of money for chip development and research.

I came across Intel’s white paper “Migration from UNIX/RISC and Mainframe to Intel-based Solutions”. They claim that many companies have benefited by migrating to Intel processor in terms of flexibility, lower costs and reliability. I need to find out is it necessary or rather is it really beneficial?
