Position of the Northbridge and Southbridge on a Motherboard

A northbridge or host bridge is one of the two chips in the core logic chipset architecture on a PC motherboard , the other being the southbridge. Unlike the southbridge, northbridge is connected directly to the CPU via the front-side bus FSB and is thus responsible for tasks that require the highest performance. The northbridge, also known as Memory Controller Hub, is usually paired with a southbridge. Increasingly these functions became integrated into the CPU chip itself, [3] beginning with memory and graphics controllers.

Separating the different functions into the CPU, northbridge, and southbridge chips was due to the difficulty of integrating all components onto a single chip.

As CPU speeds increased over time, a bottleneck eventually emerged between the processor and the motherboard , due to limitations caused by data transmission between the CPU and its support chipset. Modern Intel Core processors have the northbridge integrated on the CPU die, where it is known as the uncore or system agent.

Because different processors and RAM require different signaling, a given northbridge will typically work with only one or two classes of CPUs and generally only one type of RAM. There are a few chipsets that support two types of RAM generally these are available when there is a shift to a new standard.

The name is derived from drawing the architecture in the fashion of a map. The CPU would be at the top of the map comparable to due north on most general purpose geographical maps.

The CPU would be connected to the chipset via a fast bridge the northbridge located north of other system devices as drawn.

The northbridge would then be connected to the rest of the chipset via a slow bridge the southbridge located south of other system devices as drawn. The northbridge plays an important part in how far a computer can be overclocked , as its frequency is commonly used as a baseline for the CPU to establish its own operating frequency.

This chip typically gets hotter as processor speed becomes faster, requiring more cooling. There is a limit to CPU overclocking, as digital circuits are limited by physical factors such as rise, fall, delay and storage times of the transistors , current gain bandwidth product, parasitic capacitance , and propagation delay , which increases with among other factors operating temperature ; consequently most overclocking applications have software-imposed limits on the multiplier and external clock setting.

Additionally, heat is a major limiting factor, as higher voltages are needed to properly activate field effect transistors inside CPUs and this higher voltage produces larger amounts of heat, requiring greater thermal solutions on the die.

The overall trend in processor design has been to integrate more functions onto fewer components, which decreases overall motherboard cost and improves performance. One of the advantages of having the memory controller integrated on the CPU die is to reduce latency from the CPU to memory.

On nForce4 boards it was marketed as a media communications processor MCP. The northbridge was replaced by the system agent introduced by the Sandy Bridge microarchitecture in , which essentially handles all previous Northbridge functions. From Wikipedia, the free encyclopedia.
