Microprocessor
The processor, also known as the CPU, can be thought of as the brains of the system and is responsible for executing software commands and performing calculation functions. The following table shows the features of the various Intel processors.

- With the Pentium MMX processors, 57 multimedia specific instructions were added to increase multimedia performance and increased the L1 cache size to 32KB.
- The Pentium Pro added Dynamic Execution and increase L2 cache to 512KB.
- The Pentium II had integrated MMX technology and used a new Single Edge Contact Cartridge(SEC).
- The Pentium III provided increased processor speeds, a 100mhz front size bus speed and increased L2 cache to 512KB.
- The Celeron processors are less expensive but only have a 66mhz bus and 128KB L2 cache.
- The Pentium IV introduced a number of graphics enhancements. 2 versions were made - The first was a 423-pin PGA package with 256 KB L2 cache. The second version offers a 478-pin PGA package with 512 KB of L2 cache.
- Intel Xeon processors are higher-end and based on their Pentium II, III and IV counterparts.
