ATI makes a bold journey into the world of AMD chipsets with its Radeon Xpress 200 chipset. The Register have a review of a ATI Radeon Xpress 200G reference board, ATI's first attempt at a PCI Express chipset.
Two different versions of the Xpress 200 chipset are available: the P and the G, but the one reviewed is the G version. The only difference is that the P version does not have integrated graphics. The included SurroundView technology makes it possible for the integrated graphics to work in conjunction with a PCI Express graphics card and gives you the opportunity to use an additional monitor. The Radeon Xpress 200 chipsets supports 22 PCI Express lanes with 16 of these dedicated to the x16 PCI Express graphics slot, while four can be used to either provide expansion slots or on-board peripherals. There is native support for up to four Serial ATA 150 devices and four IDE devices, up to eight USB 2.0 ports and eight-channel AC97 audio. The SATA controller supports RAID 0 and 1, but not 0+1, unfortunately.
