Technology at a Cross-Roads
Not too many years ago, industry pundits predicted that microprocessors based on RISC
(Reduced Instruction Set Computer) computing, an architecture that reduces chip complexity by
using simpler instructions, would forever out-perform current x86 processors based on CISC
(Complex Instruction Set Computer) architectures, which use microcode to execute very
comprehensive instructions.
Yet today, CISC processors essentially match RISC chips in integer performance, and are
quickly catching up on floating point performance. As can be seen in the chart below, x86
performance has nearly erased a 50% SPECint benchmarking deficit when compared to RISC
performance over the past four years. SPECint is a set of eight compute-intensive integer/non-
floating point benchmarks used to measure typical processor performance.
Future gains in performance are anticipated to have less to do with instruction sets than with
implementation techniques. Therefore, any decision adopting 64-bit RISC or VLIW (Very Long
Instruction Word) based processors over 64-bit CISC based processors will likely offer little if
any advantage in overall processor performance.
