  1. Motherboards and CPUs Management Information Systems Reference: graphics and models are taken from web sources.

  2. Speed – the more we get, the more we want

  3. Interfaces hold it all together

  4. An interface connects two hardware devices. An interface can consist of controllers with built-in software, cables, etc.

  5. An example of Interface

  6. Data Exchange on motherboard

  7. Motherboard – a hub of all data exchange

  8. Motherboard

  9. Power Supply

  10. Sockets

  11. Connectors

  12. Another connector!

  13. Some more connectors…

  14. Pentium 4 Socket

  15. Finding out CPU?

  16. On startup screen…

  17. If you are a motherboard nerd…WCPUID / CPU-Z

  18. Buying motherboards… • Mostly produced in Taiwan • Microstar, Asus, Epox, Soltek… • Figure out compatibility with processor • Decide for latest chipset for max. functionality • Typically: • USB version 2.0. • Dual channel RAM. • Support for 400 and 533 MHz DDR2 RAM. [lately 667Mhz] • Integrated Firewire ports. • Serial ATA. • Surround sound. • Gigabit Ethernet.

  19. Extra Facilities… • Built-in RAID controllers or SCSI controller • Other network screen and sound facilities • Wireless LAN [802.11a/b/g] • SmartCard / MemoryStick /etc. readers.

  20. CPU Clock Speeds

  21. CPU Transistors

  22. Technology • Millions of transistors • Connected through ultra thin electronic tracks • Width of track – 0.09 and 0.06 microns (micrometer) • Important to cool – (consumes 50-120 Watts)

  23. Progression in tracks nearness!!

  24. A powerful fan!

  25. Caches • Ram is slower [533 or 677Mhz as compared to CPU] • L1, L2, and L3 caches are used. • CPU typically is only utilizing 35% of clock ticks. • remedy against “bottleneck”. • Latency!!!

  26. L2 – an old implementation

  27. Caches orientation

  28. FSB Speed

  29. Processors and caches

  30. Multiprocessors • Xeon, Opteron (64 bit) • 2,4, or even 8 • Typically used as servers but can work as powerful workstations • Special version of software to take advantage of the capability.
