Ati Ixp 400

The IXP 400 (Integrated Communications Processor) is ATI’s second-generation Southbridge. It was commonly paired with the or RS480 Northbridge (for Intel) and RX480/RX482 (for AMD). It is known for being the first ATI southbridge to include native SATA support, though without AHCI.

The ATI IXP 400 had a significant impact on the computer industry, particularly in the areas of gaming and high-performance computing. Its high-quality audio and video capabilities, combined with its support for PCI Express and Serial ATA, made it a popular choice among gamers and power users.

Key features of the ATI IXP 400 included: ati ixp 400

: The chipset integrated two independent SATA controllers, supporting up to four SATA devices and RAID 0 and 1 configurations.

The ability to support two PATA channels (four devices) alongside four SATA drives meant builders could transition slowly. You could keep your DVD burner on PATA and your new hard drive on SATA without conflicts. The IXP 400 (Integrated Communications Processor) is ATI’s

Unlike the buggy initial releases of ATI’s earlier southbridges (the IXP 200/300 series), the 400 series benefited from mature Windows XP drivers. Microsoft even included native drivers for it in Windows XP SP2, meaning clean installs worked without floppy disks. The ATI IXP 400 had a significant impact

The IXP 400 also played a key role in the adoption of PCI Express, which eventually became a widely adopted standard in the computer industry. Additionally, the IXP 400's integrated design and high-performance capabilities helped to drive the development of more compact and efficient system designs.

The (also known as the SB400) is a Southbridge chipset released in late 2004 that played a critical role in ATI's efforts to compete in the integrated graphics and motherboard market. Paired most notably with the Radeon Xpress 200 Northbridge, it was designed to provide essential connectivity and I/O management for both AMD and Intel-based systems. Evolution and Context

The ATI IXP 400 boasted several key features that made it a standout in the chipset market. Some of its notable features include:

In 2006, ATI was acquired by AMD, which has since continued to develop and release high-performance chipsets and GPUs. The IXP 400's impact on the computer industry can also be seen in the many modern chipsets that have followed in its footsteps, incorporating similar design principles and features.
