Fig. 147. The architecture surrounding the Intel® 82875P Memory Controller Hub (MCH). Another new feature in this chip set is that a Gigabit Ethernet controller can have direct access to the MCH (the north bridge). Traditionally the LAN controller is connected to the PCI bus. But since a gigabit network controller may consume a great band width, it is better to plug it directly into north bridge. This new design is called Communication Streaming Architecture (CSA).
Figur 148. Report from the freeware program CPU-Z. The i925 chipset In late 2004 Intel introduced a new 900-series of chipsets. They were intended for the new generation of Pentium 4 and Celeron processors based on the LGA 775-socket (as in Figur 112 at page 44). The chip sets comes with support for the PCI Express bus, which is replacing the AGP bus and with support of DDR2 RAM:
