ARM7 is an architecture, not a specific model. ARM7 processor can be made by any licensee of the technology to suit their needs. As such, their clock frequencies can range anywhere from 1 Mhz to 2.5 GHz.

The 8086 processor's operating frequency is derived from the crystal frequency through a process of division. Typically, the crystal frequency is set at a multiple of the desired processor frequency, often using a frequency divider. For instance, if the crystal frequency is 5 MHz, the 8086 can operate at 5 MHz, but with external circuitry, it can also achieve other frequencies based on the design of the clock circuits. Thus, the crystal frequency serves as the fundamental timing source for the processor's operation.

2.2 GHz is a processor frequency, and 800 MHz is a FSB frequency. First defines how many operations can the processor does; second one defines how much information the processor transfers to other components of computer.
It tells you how many operations per second your processor is capable to do. The higher frequency is better. Also you have to take in count a number of cores.
