If you're comparing an Intel processor with an AMD or Cyrix processor, you could head for the PC Magazine article CPU choices to see how these processors compare in testing. So far, though, on the basis of processor alone, the Blue company is the best buy. Keep in mind that the question here isn't what the system might actually include, but what you can conclude from the ads. Many readers will decide from the ad itself which system or systems to pursue. Next comes system memory.
RAM costs money.
The Blue company and the Red company systems are tied here, both because of the equal amount of RAM provided and because they're listed as high-performance. We'll give the Red company the slight edge, because it specifies the 100-Mhz speed of the system memory. But the ad should make that clear, and it doesn't. We now move to the hard drive, which is always a major consideration. Unbelievably, the Green company ad doesn't tell us anything about the hard drive, but we have to assume there is one.
