Architecture: Basic design of a microprocessor. May include process technology and/or other architectural enhancements.

Cache (MB/KB): A temporary storage area for frequently accessed or recently accessed data. Having certain data stored in a cache speeds up the operation of the computer. Cache size is measured in megabytes (MB) or kilobytes (KB).

Front Side Bus: The connecting path between the processor and other key components such as the memory controller hub. FSB speed is measured in GHz or MHz.

Clock Speed: Speed of the processor's internal clock, which dictates how fast the processor can process data. Clock speed is usually measured in GHz (gigahertz, or billions of pulses per second).
