- Hard Disk
- Processor is the brain of your computer.
- Some key concepts
- Clock : In a computer, clock speed refers to the number of pulses per second that sets the tempo for the processor.
- 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
- Cyrix C3
- Itanium (64 bit)
- Opteron (64 bit)
Choosing the right Processor
- How do you pick a processor for your system?
- Performance & Cost
- How to measure
- Clock speed is one measure of computer “power”, but it is not always directly proportional to the performance level.
- The type of microprocessor, the bus architecture, and the nature of the instruction set, all make a difference.
- examples : P4 3.06 GHz, P4 3.0B GHz, P4 3.0C GHz
- Check for bus speed and cache size as well.
