Primary liaison with the other components is the processor chipset. On the chipset that consists of some part, where this part certainly more influential on overall system performance. Besides concerned, the performance is influenced by the magnitude of the path that connects to the processor. Like the highway, the more his lane, the more cars can pass each second.
Similarly, the line between the Northbridge premises n processors, the greater the available bandwidth the more data that can be passed every second. The path connects the northbridge to the processor that is used when it is the FSB (Front Side Bus). The amount of bandwidth that is when it is sometimes insufficient when using components that have very high performance.
Various barriers and electrical interference can be minimized so that the connection with high bandwidth can be used. After integrating the memory controller, northbridge functions such as PCI-Express controller to follow. The graphics card is integrated on the processor pin partake in.. Now, on a variety of Intel and AMD desktop system new, has been integrated northbridge to the processor, the latest desktop systems still use a separate northbridge AMD AM3 + is a system with its 9-series chipset.
PCH AND FCH
Southbridge used by mainstream desktop systems today called the Intel PCH, while desktop systems AMD A series APU called FCH. One of the newest is BD82Z77 PCH also known as Intel Z77 express chipset, while the latest one is the A75 FCH. Both chipsets have supported the new interface and the popular range of SATA 6Gbps USN 3.0, but for SATA 6Gbps, AMD A 75 supports up to 6 channels, while the Intel Z77 Express only to 2 channel.
Other standards also support each offer. The difference in this implementation interesting. Both Intel Z77 has the same path bandwidth to the processor with 2GB call the DMI 2.0 while AMD calls with UMI. A lane PCI-Express 2.0 offers speeds up to 500 MB, but with the other facilities also require bandwidth bottleneck possibility of course remains.
For example, support for USB 3.0 and SATA 6Gps available on Intel Z77 express or AMD A75. USB 3.0 offers speeds up to 500 MB, while the SATA 6Gbps to 600 MB. If you sum it all goes as well as the maximum, which is owned bandwidth between the processor southbridge, both intel and AMD, is insufficient. Even so, this course has been taken into the performance.
