Line 75:

There are several different markets in which CPUs are used. Since each of these markets differ in their requirements for CPUs, the devices designed for one market are in most cases inappropriate for the other markets.

===General -purpose computing===

{{As of|2010}}, in the general-purpose computing market, that is, desktop, laptop, and server computers commonly used in businesses and homes, the Intel [[IA-32]] and the 64-bit version [[x86-64]] architecture dominate the market, with its rivals [[PowerPC]] and [[SPARC]] maintaining much smaller customer bases. Yearly, hundreds of millions of IA-32 architecture CPUs are used by this market. A growing percentage of these processors are for mobile implementations such as netbooks and laptops.<ref>Kerr, Justin.
