A chipset is the primary interconnect between components not directly connected to the [[CPU]] and the [[CPU]], it handles pretty much all data which is circled around on the secondary I/O devices. This can make the link between the chipset and the [[CPU]] a major bandwidth bottleneck. Often you only have a 4x [[PCIe]] lane wide link between it and the [[CPU]], but about 24 lanes of PCIe devices on the chipset, though on some chipsets it is less pronounced than on others. | |||
There was a time where a time where motherboards had a set of chips, which is why we call it chipset, where a "northbridge" handles the connection to the primary PCIe devices, the RAM and the "southbridge". The "northbridge" was connected to the CPU through the FSB (front-side bus). The "southbridge" we still have today, this component is what we call the chipset today. | |||
