Intel P45
Encyclopedia
The P45 Express is a mainstream desktop computer chipset
from Intel released in Q2 2008. The first mainboards featuring the P45 chipset were shown at CeBIT
2008.
The P45 Express chipset supports Intel's LGA 775 socket and Core 2 Duo and Quad processors. It is a 65nm
chipset, compared to the earlier generation chipsets (P35, X38, X48) which were 90nm. P45 was also the last Intel chipset to employ a north
and south
bridge (MCH/ICH
); all current and future Intel chipsets make use of the PCH
architecture.
Chipset
A chipset, PC chipset, or chip set refers to a group of integrated circuits, or chips, that are designed to work together. They are usually marketed as a single product.- Computers :...

Northbridge (computing)
The northbridge has historically been one of the two chips in the core logic chipset on a PC motherboard, the other being the southbridge. Increasingly these functions have migrated to the CPU chip itself, beginning with memory and graphics controllers. For Intel Sandy Bridge and AMD Fusion...

Southbridge (computing)
The southbridge is one of the two chips in the core logic chipset on a personal computer motherboard, the other being the northbridge. The southbridge typically implements the slower capabilities of the motherboard in a northbridge/southbridge chipset computer architecture. In Intel chipset...

Platform Controller Hub
The Platform Controller Hub is a family of Intel microchips. I/O Functions have been reassigned between the PCH, a new central hub, and the CPU. Some northbridge functions, the memory controller and PCI-e lanes, were integrated into the CPU while the PCH took over the remaining functions in...
