The Need for Processing Power One of the reasons for the popularity of sub-$1000 PCs is a lack of mainstream applications that are demanding enough to convince the buyers to opt for more powerful systems. In earlier days, a marked difference in performance of mainstream applications (e.g., business productivity applications such as word processors and spreadsheets) was apparent between lower end machines and higher end machines. For many, such difference justified the extra expense of higher end machines. But even entry-level computers perform admirably today on those applications, and the improvement in performance on more expensive systems is apparent only to benchmarks. (As an aside, the diminishing returns are not just a matter of perception. The percentage increase in the clock speed between a 33 MHz 486 and a 50 MHz 486 chip is equivalent to that between a 233 MHz Pentium II and a 350 MHz Pentium II. Of course, we now appear to have three additional speed grades - 266 MHz, 300 MHz, and 333 MHz - in the middle.) Clearly, to sell the higher end chips, applications that are hungry for processing power are necessary. Some had hoped that the World Wide Web, with its rich graphics and multimedia content, would be such a "killer application." At least for the average home user connecting to the Internet via a POTS modem, the bandwidth and not the CPU is the bottleneck for such applications. In the business world, a significant number of computers are used primarily for word processing, presentation graphics, spreadsheets, etc., which as discussed earlier, do not always justify the extra processing power. While it is true that some people, such as game players and software developers, can certainly use the extra horsepower that comes with the higher-end processor, the question is what percentage of the market do they represent? Does this mean that I think we have reached a saturation point in terms of the need for processing power? Absolutely not. Would the average Joe require more powerful computers in the future than available today? Without a doubt. With applications like digital photography, speech recognition, and videoconferencing on the mass-market horizon, the need for higher-powered machines in the future is inevitable. However, it would be a fallacy to immediately extrapolate that into a rosy scenario for Intel, for the right question is not whether more powerful applications would become mainstream in the future (they would), but whether the more powerful applications would become mainstream in such a rapid fashion to once again begin to outpace the hardware offerings of the time. An example would perhaps best illustrate the above point. Next year's computers would be more powerful than today's computers at the same price point. Perhaps today's top-of-the-line processor will be found in next year's entry-level machines (if you doubt that, remember that a Pentium 200 MHz MMX was the top performer at this time last year, and with HP's $799 machine it is becoming the entry point today). If Moore's law continues to hold, the same will be true for the subsequent year, and so on. If digital photography takes, say, three years to gain mass-market acceptance, the entry-level machines of those days may be adequate for the application anyway, thus providing little upside for Intel. (By the way, the three year estimate is quite optimistic: just look at the acceptance of APS in the photography marketplace.) In short, the right question is not whether more demanding applications become mainstream, but when will they become mainstream. One reason for buying more than what you may need today is insurance against rapid obsolescence. However, that argument is getting weaker in this era of cheap PCs. You can buy a capable $799 PC today, and when it becomes obsolete a couple of years later, hopefully buy a similarly priced (but much more powerful) PC down the road, for a total life span longer than what $1600 would buy you today.
