  1. Interesting, but one nitpick by LizardKing · · Score: 3, Informative

    Definitely an interesting article, and I'm even inclined to read some of the authors stuff. However, he might need to clarify that bit about the Dhrystone benchmark being thirty or more years old. If it is, then it wasn't written to allow comparison against the performance of the Vax as he claims. The first Vax systems didn't ship until the late 1970's, a little over twenty years ago.

    There is one. The argument he's debunking:
    If performance is increased, the cost will increase; if the cost is increased, the price will increase. Therefore, a higher-priced CPU delivers higher performance.
    The problem with that argument:
    Price and cost are unconnected: the price will move up or down regardless of the cost.
    It's not terribly clear because he omitted a step from the argument, but I suppose otherwise the title for that section would be too long and unwieldy.
