8.1. PC Hardware

The client hardware for the Web is mostly standard PC hardware these days, even though there still are a significant number of Macintoshes and network appliances like the Javastation and WebTV are gaining in popularity. In this chapter, I will concentrate on the components of PC client hardware, because the components differentiate the packages. There is still a great deal of standardization and interchangeability of components at this level, resulting in healthy competition and many price versus performance options.

8.1.1. CPU

8.1.1.1. Do you need a fast CPU?

The most important thing to remember about web client CPUs is that they're not terribly important. PC hardware is almost always overendowed with CPU relative to bus. That is, an extremely fast CPU will probably spend most of its time waiting for the bus to catch up with it. Nonetheless, the CPU frequency and model is what sells the machine, so manufacturers are forced to supply the latest and fastest CPU even if the previous generation of CPU would do just fine for most people. Web access speed is influenced much more by disk and network I/O than by CPU or even bus speed.
