I’m looking at building myself a new PC for the first time in years. That’s a little bit of a misnomer though. Today, building a PC can mean bolting as few as two components into a case and connecting four cables. Building PCs in the 1990s was a lot more difficult. I remember in 1994, during one of my first builds, someone walking past in the hall, looking at the mess of cards and cables, and asking, “How do you know which one goes where?”
Today, the assembly is pretty easy. Figuring out what to buy is harder. In 1994, the differences between the various flavors of 386 and 486 chips available was confusing, but it all fit on an index card. Mainly the difference came down to the amount of memory the chip could address (386) and whether it had a math coprocessor (486). Beyond that all you really had to worry about was clock speed. Back then the research took 30 minutes and the system took hours to build.
Today there are two chip manufacturers (down from four) but they both have half a dozen product lines. And nobody really talks about clock speed anymore. That’s fine because clock speed was a crude measure of performance, but is throwing numbers like 560 or 840 or 965 on the chips really any better? Today the research takes hours (if not days) and the system goes together in about 5 minutes. Shake the bag right and it could just come out of the bag fully assembled.
