Intel i945GC northbridge with Pentium Dual-Core microprocessor. This article provides a list of motherboard chipsets made by Intel, divided into three main categories: those that use the PCI bus for interconnection (the 4xx series), those that connect using specialized "hub links" (the 8xx series), and those that connect using PCI Express (the 9xx series).
In a computer system, a chipset is a set of electronic components on one or more integrated circuits that manages the data flow between the processor, memory and peripherals. The chipset is usually found on the motherboard of computers. Chipsets are usually designed to work with a specific family of microprocessors.
CPU-Z is a freeware system profiling and monitoring application for Microsoft Windows and Android that detects the central processing unit, RAM, motherboard chipset, and other hardware features of a modern personal computer or Android device.
The chipsets contain a 'memory controller hub' and an 'I/O controller hub', which tend to be called 'north bridge' and 'south bridge' respectively. The memory controller hub connects to the processors, memory, high-speed I/O such as PCI Express, and to the I/O controller hub by a proprietary link.
The southbridge typically implements the slower capabilities of the motherboard in a northbridge-southbridge chipset computer architecture. In systems with Intel chipsets, the southbridge has been named I/O Controller Hub (ICH) and later replaced by Platform Controller Hub chipsets. In older Intel/AMD architectures the southbridge is usually ...
AMD chipsets logo. This is an overview of chipsets sold under the AMD brand, manufactured before May 2004 by the company itself, before the adoption of open platform approach as well as chipsets manufactured by ATI Technologies after October 2006 as the completion of the ATI acquisition.
A typical north/southbridge layout (2015) A typical north/southbridge layout (2007) In computing, a northbridge (also host bridge, or memory controller hub) is a microchip that comprises the core logic chipset architecture on motherboards to handle high-performance tasks, especially for older personal computers.
Under the Hub Architecture, a motherboard would have a two piece chipset consisting of a northbridge chip and a southbridge chip. Over time, the speed of CPUs kept increasing but the bandwidth of the front-side bus (FSB) (connection between the CPU and the motherboard) did not, resulting in a performance bottleneck.
