One of the advantages of having the memory controller integrated on the CPU die graohics to reduce latency from the CPU to memory. Please help improve this article by adding citations to reliable sources.

Retrieved January 4, Unsourced material may be challenged and removed. Separating the different functions into the CPU, northbridge, and southbridge chips was due to the difficulty of integrating all components onto a single chip.

There is a limit to CPU overclocking, as digital circuits are limited by physical factors such as rise, fall, delay and storage graphocs 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.

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. This article needs additional citations for verification. 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.

Because different processors and RAM require different signaling, a given northbridge will typically work apg only one or two classes of CPUs and generally only one type of RAM. This page was last edited on 8 Octoberat Encyclopedia of computer science and technology.

This chip typically gets hotter as processor speed becomes faster, requiring more cooling. Computer Science portal Electronics portal. Views Read Edit View history. There is a way, says system-level security inyel. The northbridge was replaced by the system agent introduced by the Sandy Bridge microarchitecture inwhich essentially handles all previous Northbridge functions.

Retrieved from ” https: Retrieved Graphocs 26, A northbridge or host bridge is one of the two chips in the core logic chipset architecture on a PC motherboardthe other being the southbridge.

There are a grphics chipsets that support two types of RAM generally these are available when there is a shift to a new standard. The CPU would be connected to the chipset via a fast bridge the northbridge located north of other system devices as drawn.

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

New York, NY [u. The CPU would be at fmch top of the map comparable to due north on most general purpose geographical maps.

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. From Wikipedia, the free encyclopedia.

Increasingly these functions became integrated into the CPU chip itself, [3] beginning with memory and graphics controllers. The name is derived from drawing the architecture in the fashion of a map. The overall trend in processor design has been to integrate more functions onto fewer components, which decreases overall motherboard cost and improves performance.

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. 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.
