Submission + - Research Shows RISC vs CISC Doesn't Matter 1

fsterman writes: The power advantages brought by the RISC instruction sets used in Power and ARM chips is often pitted against the X86's efficiencies of scale. It's difficult to asses how much the difference between instruction sets matter because teasing out the theoretical efficiency of an ISA from the proficiency of a chip's design team, technical expertise of its manufacturer, and support for architecture-specific optimizations in compilers is nearly impossible . However, new research examining the performance of a variety of ARM, MIPS, and X86 processors gives weight to Intel's conclusion: the benefits of a given ISA to the power envelope of a chip are minute.
