Xpress 200


The Radeon Xpress 200 is a computer chipset released by ATI. The chipset supports AMD 64-bit processors as well as supporting Intel Pentium 4, Pentium D and Celeron processors. Additionally, it includes support for DDR400 RAM and DDR-2 667 RAM on the Intel Edition.
ATI renamed its Radeon Xpress 200 Crossfire Edition chipset to CrossFire Xpress 1600. After the takeover from AMD, AMD renamed the Crossfire Xpress 1600 chipset for AMD socket AM2 platform to the AMD 480X CrossFire chipset.

Types

The Radeon Xpress 200 comes in five different versions:

SB400 (IXP 400), M1573 (RS480)

The Radeon Xpress 200 chipset can make use of different southbridges, one of them is the SB400 , providing 2 ATA channels, 2 SATA 1.5 Gbit/s interface 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 chipset is an upgrade to the RS480 chipset which still uses the branding, with the distinction of abandoning sideport memory support 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 SATA 1.5 Gbit/s interface 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.
