Some key concepts Clock : In a computer, clock speed refers to the number of pulses per second that sets the tempo for the processor. Cache A small but fast memory area. Levels of cache exists. Bus (FSB and BSB) : Collection of wires connecting different devices. Pipeline : Implementation technique where multiple instructions are overlapped. 32/64 bit processors The amount of data a processor can process in a clock cycle. Clock speed and overclocking BUS SPEED x MULTIPLIER = CPU SPEED (Clock) Which processor is faster? 100MHz x 10.0 = 1000 MHz 133MHz x 7.5 = 997.5 MHz Some commercially available processors Pentium I-IV Celeron Athlon Duron Cyrix C3 Itanium (64 bit) Opteron (64 bit) Choosing the right Processor How do you pick a processor for your system?
