My question for you is "Why is this a reasonable means of comparing computing power for the money?" The reason why MIPS seems like a problematic unit of comparison to me is that different machines have different instruction sets. Some instruction sets are far more complex than others. For example, what a Symbolics 3600 and a VAX workstation can do in a single instruction might require half a dozen instructions or so on a RISC workstation. Could someone shed some light on this for me? +---------------------------------------------------+-------------------------+ | "The pain was enough to make a shy, bald buddhist | Edan Kabatchnik | | reflect and plan a mass murder." | enk@slcs.slb.com | | - The Smiths | enk@wheaties.ai.mit.edu | +---------------------------------------------------+-------------------------+
