Motherboards & CPUs

1. Motherboards & CPUs Team 3

2. Motherboard Characteristics (wooo) • A motherboard has several Characteristics • Form Factor • Chipset • CMOS & Battery • BIOS • RAM • Expansion Slots/Busses • Input & Output Connectors  • CPU & Socket

3. Motherboard Characteristics - Form Factor • Form Factor  • The size/shape of a motherboard

4. Motherboard Characteristics - Chipset  • The chipset controls communication between the processor and external devices. (The faster the chipset the faster the performance)  • Consist of the North Bridge and the Southbridge • The Northbridge - links the CPU to high speed components such as the RAM and Graphics Adapter(sometimes integrated) • The Southbridge - handles all of the computers I/O functions and communication such as with components like the BIOS hard drive, audio, keyboard, mouse

6. Motherboard Characteristics - CMOS & BIOS • The BIOS is the basic input/output system of the computer  • It is the first code run by a PC when powered on and it identifies the system devices and components it then it loads the bootloader software giving it control. It is stored in Read-Only Memory(ROM) • The CMOS (complementary metal-oxide semiconductor) is and on-board semiconductor chip which is powered by battery (usually last around 10 years) and stores information such as the system hardware settings and the system date and time • The CMOS information is used by the BIOS 

8. Random Access Memory Controls how fast the computer can access instructions and data Controls how much data the computer can have readily available  dual data rate (DDR) memory  DDR2  DDR3 Motherboard Characteristics - RAM

9. Motherboard Characteristics - Sockets Pin Grid Array (PGA)   Variations of PGAs • Socket 478 - for older Pentium and Celeron processors • Socket 754 - for AMD Sempron and some AMD Athlon processors • Socket 939 - for newer and faster AMD Athlon processors • Socket AM2 - for the newest AMD Athlon processors • Socket A - for older AMD Athlon processors Land Grid Array (LGA)      pins are actually part of the socket, not the CPU

10. Circuit that connects one part of the motherboard to another Speed      measured in megahertz (MHz) Motherboard Characteristics - Busses

11. I/O or (input/output) Connectors is basically an interface to link devices devices Motherboard Characteristics - I/O Connect

13. CPU

14. Selection Methods 1. Brands: Intel or AMD (for traditional computers), ARM (for mobile devices) 2. Types: Mobile, desktop, laptop, or server. 3. Series: Examples; Core 2 Duo, Core i7, Athlon 64 x2   Difference between series: • Size • Number of cores • The core that is utilized • Thermal power design (TPD) • Price  4. Cpu socket type: (AM2, AM2+, AM3, LGA 775, LGA 1156 and        LGA 1366)

15. Selection Methods Cont. 5. Core:   AMD: • Regor (Athlon II X2) • Deneb (Phenom II X4) • Propus (Athlon II X4)    Intel: • Wofldale (Core 2 Duo E6300, E7xxx and E8xxx)  • Yorkfield (Core 2 Quad Q8xxx and Q9xxx) • Nehalem (socket 1366 i7) • Lynnfield (socket 1156 i5 and i7)  6.  Multi-core: Dual, Triple, Quad, Six+

16. Selection Methods Cont. 7. Frequency: Speed at which the processor runs 8. FSB, Hyper-transport or QPI: Speed at which processor communicates with other components.  9. L2/L3 Cache: On board CPU memory (much faster than RAM) 10. 32-bit or 64-bit: Updated 64-bit allows for greater amount of memory in the computer. 11. Manufacturing Technology: Measured in nm, the smaller the number the more transistors on the surface and the less power used. 12. Thermal Power Design: Indicates how much power that the cpu will use in the worst case scenario.
