Southbridges can be chosen between ATI SB450, SB460 and ULi M1575.
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. 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. 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.
Motherboards utilizing this chipset will feature two 16x PCI-Express slots (although, like early SLI chipsets, they only operate at 8x when CrossFire is enabled, unlike some newer CrossFire and SLI capable chipsets where both slots retain full speed).It is designed to compete with nVidia's SLI technology. This adds support for ATI's multi-GPU technology called Crossfire.Radeon Xpress 200 chipset optimized for Mobile applications.Later renamed as Radeon Xpress 1150 for AMD notebooks.The integrated graphics are based on the ATI Radeon X300 GPU with full OpenGL 2.0 and DirectX 9.0 support.Support for 4 SATA and 4 PATA drives, which can be linked together in any combination of SATA and PATA to form a RAID 0, 1, or 0+1.Support for up to 22 PCI Express lanes.
The Radeon Xpress 200 comes in five different versions: After the takeover from AMD, AMD renamed the Crossfire Xpress 1600 chipset for AMD socket AM2 platform to the AMD 480X CrossFire chipset. Additionally, it includes support for DDR400 RAM and DDR-2 667 RAM on the Intel Edition.ĪTI renamed its Radeon Xpress 200 Crossfire Edition chipset to CrossFire Xpress 1600. The chipset supports AMD 64-bit processors ( Socket 939 and Socket 754) as well as supporting Intel Pentium 4, Pentium D and Celeron processors ( LGA 775 and Socket 478). The Radeon Xpress 200 is a computer chipset released by ATI.
