Comparing the speed of CPU architectures is a very complex and sometimes futile undertaking, as the platform around processors might be much more significant than the actual ISA. Still, it is historically interesting to see how different RISC architectures fared against each other in the RISC/Unix world of the 90s. While PA-RISC processors were usually faster than their competition at the same clock speed, they were expensive to fabricate. Their platform, HP 9000 with PA-RISC and HP-UX, was u...| OpenPA.net
