Northbridge (computing) – Wikipedia

Unlike the southbridge, northbridge graphica connected directly to the CPU via the front-side bus FSB and is thus responsible for tasks that require the highest performance. Please help improve this article by adding citations to reliable sources. From Wikipedia, the free encyclopedia.

Increasingly these functions became integrated into the CPU chip itself, [3] beginning with memory and graphics controllers. This article needs additional citations for verification.

January Learn how and when to remove this template message. The name is derived from drawing the architecture in the fashion of a map. 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 transistorscurrent gain bandwidth product, parasitic capacitanceand propagation delaywhich increases with among other factors operating temperature ; consequently most overclocking applications have software-imposed limits on the multiplier and external clock setting.

One of the advantages of having the memory controller integrated on the CPU die is to reduce latency from the CPU to memory. 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.

Unsourced infel may be challenged and removed. The CPU would be at the top of the map comparable to due north on most general purpose geographical maps.

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. Modern Intel Core processors have the northbridge integrated on the CPU die, where it is known as the uncore or system agent.

Retrieved January 4, Separating the different functions into the CPU, northbridge, and southbridge chips was due to the difficulty of integrating all components onto a single chip. On nForce4 boards it was marketed as a media communications processor MCP. New York, NY [u. As CPU speeds increased over time, a bottleneck eventually emerged between the processor and the motherboarddue to limitations caused by data transmission between the CPU and its support chipset.

The overall trend in processor design has been to integrate more functions onto fewer components, which decreases overall motherboard cost and improves performance.

There are a few chipsets that support two types of RAM generally these are available when there is a shift to a new standard. This chip typically gets hotter as processor speed becomes faster, requiring more cooling.

There is a way, says system-level security ace”. The gmmch was replaced by the system agent introduced by the Sandy Bridge microarchitecture inwhich essentially handles all previous Northbridge functions.

Views Read Edit View history. 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 northbridge plays an important part in how far a computer can be overclockedas its frequency is commonly used as a baseline for the CPU to establish its own operating frequency. Computer Science portal Electronics portal.
