Difference Between Clock Speed and Bus Speed

Clock Speed vs Bus Speed

Summary: Difference Between Clock Speed and Bus Speed is that the pace of the system clock, called the clock speed, is measured by the number of ticks per second. Current personal computer processors have clock speeds in the gigahertz range. While Every bus also has a clock speed. Just like the processor, manufacturers state the clock speed for a bus in hertz.

Difference Between Clock Speed and Bus Speed

Clock Speed

The pace of the system clock, called the clock speed, is measured by the number of ticks per second. Current personal computer processors have clock speeds in the gigahertz range. Giga is a prefix that stands for billion, and a hertz is one cycle per second. Thus, one gigahertz (GHz) equals one billion ticks of the system clock per second. A computer that operates at 3 GHz has 3 billion (giga) clock cycles in one second (hertz). The faster the clock speed, the more instructions the processor can execute per second. The speed of the system clock is just one factor that influences a computer’s performance. Other factors, such as the type of processor chip, amount of cache, memory access time, bus width, and bus clock speed.

Bus Speed

Every bus also has a clock speed. Just like the processor, manufacturers state the clock speed for a bus in hertz. Recall that one megahertz (MHz) is equal to one million ticks per second. Today’s processors usually have a bus clock speed of 400, 533, 667, 800, 1066, 1333, or 1600 MHz. The higher the bus clock speed, the faster the transmission of data, which results in programs running faster.
