SB400 (IXP 400), M1573 (RS480)
The Radeon Xpress 200 (RS480) chipset can make use of different southbridges, one of them is the SB400 (IXP 400), providing 2 ATA channels (2 devices per channel), 2 SATA 1.5 Gbit/s interface (4 drives total) with RAID 0, RAID 1 and RAID 0+1 support, 7 PCI slots, 8 USB 2.0 and AC'97 codec for 5.1 and 7.1 surround sound support. Motherboard manufacturers were able to replace the SB400 southbridge with the M1573 southbridge from ULi for more versatile configuration, as well as avoiding the frequently criticized USB performance issues with ATI southbridges.
SB450, SB460, M1575 (RS482)
The Radeon Xpress 200M (RS482) chipset is an upgrade to the RS480 chipset which still uses the branding, with the distinction of abandoning sideport memory support (as frame buffer) for Z-buffer data compression support. Southbridges can be chosen between ATI SB450, SB460 and ULi M1575. For the SB450, it supports 2 ATA channels (2 devices per channel), 2 SATA 1.5 Gbit/s interface (4 drives total) with RAID 0, RAID 1 and RAID 0+1 support, 7 PCI slots, together with 8 USB support, HD Audio codec support. Note that SB450 have not implemented any network and Gigabit Ethernet PHY. With SB460 supports only maximum 2 ATA devices.
