Study Notes

CPU Performance Measurement

The power of a CPU is measured by its speed and the amount of data it can process.
CPU speed is rated in cycles per second, with common units being MHz and GHz.

Data Processing Capacity

The amount of data a CPU can process at one time depends on the size of the processor data bus.
Two types of buses that affect data processing capacity are:
- Front Side Bus (FSB), connecting the CPU to other components
- System crystal, a clock-like mechanism
