CPUS, FORM FACTOR AND SOCKETS
FORM FACTOR
Form Factor is the physical size and shape of a device.
In motherboards it pertains to the size and shape of the board and also describes the physical layout of different components and devices on the motherboard.
With system cases, it describes certain specific features and what kind of motherboard fits inside.
THE FOLLOWING ARE THE COMMON FORM FACTORS FOR
MOTHERBOARDS:
ATX (Advanced Technology Extended): 12” x 9.6” (305mm x 244mm)
Micro ATX (mATX): 9.6” x 9.6” (244mm x 244mm)
FlexATX: 9.0” x 7.5” (229mm x 191mm)
Mini ITX: 6.7” x 6.7” (170mm x 170mm)
SOCKETS
Sockets are where the CPU or processor is placed.
As microprocessors advance, they also need more and more pins
Pin Grid Array (PGA)
CPU SOCKET EXAMPLE
Socket 939 Athlon 64
The number in the names represents the number of pins present on the backside of the CPU that connect to the motherboard’s socket.
LGA (Land Grid Array)
LGA is different from PGA in that the pins are actually part of the socket, not the CPU.
Example: LGA 775
CPU PROCESSING TECHNOLOGY
Hyper-threading (officially Hyper-Threading Technology, and abbreviated HT Technology, HTT or HT) is Intel's term for its simultaneous multithreading implementation in their Xeon, Pentium 4, Atom, and Core i7 CPUs. Hyper-threading is an Intel-proprietary technology used to improve parallelization of computations (doing multiple tasks at once) performed on PC microprocessors. (www.wikipedia.org)
Hyper Threading (HT) ensures that the system resources are used most efficiently and a specific process is completed in a lesser amount of time.
Dual Core Technology combines two independent processors and their respective caches and cache controllers onto a single silicon chip.
