"Have you ever bought a car because it had an 8,000-rpm engine?" That's the rhetorical question posed by Peter Coffee, writing for eWeek in a new article entitled Clock speed is not output.

Coffee said that the complexity of modern computing systems -- their logic and the design of their I/O systems -- has more to do with how much relative horsepower they can harness. Consumers must, as Coffee said, "watch our speedometers instead of our tachometers."

Coffee approves of Apple's contribution in this arena. Coffee noted that Apple has been working for years to get buyers to focus away from what Apple calls "the megahertz myth" -- the belief that a processor working at a higher clock speed is the single most important measure of a system's performance. Ultimately, connectivity, as Coffee puts it, has a major impact on how well the computer can work.

Coffee also corrects a previous column's shortcoming by acknowledging Apple as the progenitor of the IEEE 1394 standard, known to Mac users as FireWire. He also talks about the forthcoming 1394b standard, which will up bandwidth greatly.
