New York, NY [u.
The name is derived from drawing the architecture in the fashion of a map. From Wikipedia, the free encyclopedia. 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 is a way, says system-level security ace". 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.
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.

The CPU would be connected to the chipset via a fast bridge the northbridge located north of other system devices as drawn. In other projects Wikimedia Commons. This chip typically gets hotter as processor speed becomes faster, requiring more cooling. 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 overall trend in processor design has been to integrate more functions onto fewer components, which decreases overall motherboard cost and improves performance.
Increasingly these functions became integrated into the CPU chip itself, [3] beginning with memory and graphics controllers. 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.
On nForce4 boards it was marketed as a media communications processor MCP. 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.
Modern Intel Core processors have the northbridge integrated on the CPU die, where it is known as the uncore or system agent. This page was gmcg edited on 8 Octoberat Retrieved from " https: The northbridge was replaced by the system agent introduced by the Sandy Bridge microarchitecture inwhich essentially handles all previous Northbridge functions.

One of the advantages of having the memory controller integrated on the CPU die is to reduce latency from the CPU to memory. Views Read Edit View history. There are a few chipsets that support two types of RAM generally these are available abp there is a shift to a new standard.
The CPU would be at the top of the map comparable to due north on most general purpose geographical maps. 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. 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.
