cturer of microprocessors. However; other chip manufacturers, such as Cyrix and AMD, are rapidly climbing the industry ladder to compete with Intel in the CPU marketplace. Although these other microprocessors are probably just as good as an Intel, there may be some subtle differences in them that may affect their performance. The speed of the processor is very important; this is the measure of its clock rate - which indicates the number of instructions that can be processed per second. Ten years ago, the "Intel 386" followed by the "Intel 486" processors, where considered "state-of-the-art technology". In 1993, Intel introduced their "Pentium" model microprocessors. Today, we have processor speeds available up to1GHz.
             There are also alternatives as to the model or level of CPU we can purchase. Intel produces a CPU called the "Celeron", which uses the same instruction set and software, but has a less sophisticated architecture than the "Pentium" models. "Celeron" processors are less expensive, and could mean hundreds of dollars in savings. In addition, AMD produces two microprocessors that compete with Intel's "Pentium" and "Celeron"; they are the "K6" and the "Athlon" processors. The difference in the performance of computers that use either AMD or Intel processors, are virtually impossible to uncover; they run the same software, as well as, the same peripheral devices.
             Furthermore, computers with AMD processor
