title: Will RISC architecture processors outperform that of CISC in future
body: <p>The heated discussion around the topic between CISC and RISC has never reach into a consensus, but the reality in industry turns out to be that RISC architecture processors, like ARM, PPC, etc, are seldom used as CPU in modern desktops, laptops and computation-intensive servers. They are used more on embedded computing side like phones, tablets and other mobile devices. At most recent CES 2015, ARM does not even appear there. The trend is really like that Intel with its CISC or more-CISC-less-RISC combination chip dominates the high-end processor industry with outstanding performance, whereas RISC processors are more characterized by their low power consumption targeting embedded devices. </p>
  
  <p>I would just like to know without historical and commercial reasons as well as the great effort and concentration put by Intel to push CISC forward, will RISC outperforms CISC? Or maybe in future? Especially considering that CMOS fabrication hardware complexity is approaching its limit, and more parallelism is demanded for nowadays computing, which matches the superb advantages of RISC in pipelining instructions. Besides, I would like to know if there is inherent limitation of RISC that makes it not able to compete with CISC architecture in performance?</p>
  
  <p>Different thoughts are appreciated. Thanks!</p>
