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. The overall trend in processor design has been to integrate more functions onto fewer components, which decreases overall motherboard cost and improves performance. Retrieved January 4, Encyclopedia of computer science and technology. Increasingly these functions became integrated into the CPU chip itself,  beginning with memory and graphics controllers.

The northbridge would then be connected to the rest of the chipset via a slow bridge the southbridge gmchh south of other system devices as drawn. Because different processors and Graphice require different signaling, a given northbridge will typically work with only one or two classes of CPUs and generally only one type of RAM. The northbridge was replaced by the system agent introduced by the Sandy Bridge microarchitecture inwhich essentially handles all previous Northbridge functions.
This chip typically gets hotter as processor rgaphics becomes faster, requiring more cooling. The name is derived from drawing the architecture in the fashion of a map. Encyclopedia of computer science and technology. January Learn how and when to remove this template message.

From Wikipedia, the free encyclopedia. Increasingly these functions became integrated into the CPU chip itself,  beginning with memory and graphics controllers.
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.
Retrieved from ” https: 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 ayp.

The overall trend in processor design has intle to integrate more functions onto fewer components, which decreases overall motherboard cost and improves performance. 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.
One of the advantages of having the memory controller integrated on the CPU die is to reduce latency from the CPU to memory.
Modern Intel Core processors have the northbridge integrated on the CPU die, where it is known as the uncore or system agent. New York, NY [u. In other projects Wikimedia Commons. Articles needing additional references from January All articles needing additional references.

Imtel are a few chipsets that support two types of RAM generally these are available when there is a shift to a new standard. Retrieved January 4, Separating the different functions into the CPU, northbridge, and bmch chips was due to the difficulty of integrating all components onto a single chip.
The CPU would be connected to the chipset via a fast bridge the northbridge located north of other system devices as drawn.

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.
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.
