The non-mobile ICH8 does not have a traditional PATA interface, and just one AC'97. ICH8 is offered in several different versions and is the complement to the 965 class MCH chips.

6321ESB (ESB2) Enterprise Southbridge with integrated LAN for embedded.

Originally Intel had planned to bring two further variants under the names ICH6W and ICH6RW to the market, which should contain a software Access Point for a Wireless LAN. ICH6R and ICH6-M implemented AHCI SATA controllers for the first time. The ICH6R variant supported RAID modes 0, 1, 0+1 and the Intel specific "Matrix RAID". Two additional SATA ports were added, and one PATA channel was removed. In addition, AC'97 and the classical PCI 2.3 were still supported. Support for Intel High Definition Audio was included. The bottleneck Hub interface was replaced by a new Direct Media Interface (in reality a PCI Express ×4 link) with 1 GB/s of bandwidth per direction. Faster ×16-Ports were accommodated in the MCH. It made four PCI Express ×1 ports available. ICH6 was Intel's first PCI Express southbridge. Many motherboard manufacturers had omitted the necessary high-quality safety devices for front panel connectors for cost reasons. Effective ESD preventive measures on USB ports are difficult and costly, since they can impair the quality of the USB-2.0 high-speed signals. Intel reacted to the problem by shipping ICH5 with increased ESD tolerance. In particular, when connecting USB devices via front panels, the chips died by discharges of static electricity. A cause was the insufficient ESD tolerance of certain ICH5 steppings. Since mid-2004, the large motherboard manufacturers noticed an increased complaint ratio with motherboards equipped with ICH5.

The goal of this CSA technology was to reduce the latencies for Gigabit LAN by direct memory access and to free up bandwidth on the Hub interface between ICH and MCH for non removable disk and PCI data traffic. In the new chip generation, Intel therefore offered an optional port for a Gigabit Ethernet Controller directly attached to the MCH. Since 1999 the 266 MB/s hub interface was assumed to be a bottleneck. The ICH5R variant additionally supported RAID 0 on SATA ports. In 2003, and in conjunction with the i865 and i875 northbridges, the ICH5 was created. There was also a mobile variant called the ICH2-M. The integrated AC'97 sound controller gained support for up to six channel sound. The PATA interface was accelerated to ATA/100 and the number of USB connections was doubled to four. For the first time a Fast Ethernet chip (82559) was integrated into the southbridge, depending upon an external PHY chip. An ICH2 could also be used with Intel's 82850 chipset, which, like the 82820 before it, required the use of RDRAM and supported the Pentium 4 CPU. The ICH1 or the new ICH2 (360 pins) could be placed to the side of the 82815. The hastily developed 82815 northbridge, which supported PC-133 SDRAM, became Intel's method to recover in the middle range segment. Customers were not willing to pay the high prices for RDRAM and either bought i810 or i440BX motherboards or changed to the competition. In early 2000 Intel had suffered a significant setback with the i820 northbridge.

Thus, the northbridge became the Memory Controller Hub (MCH) or if it had integrated graphics (e.g., Intel 810), the Graphics and Memory Controller Hub (GMCH). Note that, along with the ICH, Intel evolved other uses of the "Hub" terminology. Another design decision was to substitute the rigid North-South axis on the motherboard with a star structure. The Hub Interface was a point-to-point connection between different components on the motherboard. While its predecessor, the PIIX, was connected to the northbridge through an internal PCI bus with a bandwidth of 133 MB/s, the ICH used a proprietary interface (called by Intel Hub Interface) that linked it to the northbridge through an 8- bit wide, 266 MB/s bus. The first version of the ICH was released in June 1999 along with the Intel 810 northbridge.
