ATI Update: Coming to an AMD desktop near you

RS300 turned more than one head; cheap, reliable IGP performance for Intel processors. Small Form Factor PCs benifited the most from the alternative to Intel's 845G and 865G. With RS350 close to induction, today we take a look even further into the future for a glimpse at RS400 and the extremely exciting RS480.
Much like RS300, RS400 is an Intel based core logic and will still sport DX8.1 integrated graphics (Radeon 9100). Manufacturers claim the new RS400 will support the next successor to 800FSB. PCI-Express and DDR2 will also be fully supported. A-Link II appears to be a PCI-Express interconnect from the Northbridge to the Southbridge. Fortunately, we will see support for DDR and DDR2 at release.

RS480 looks to become ATI's first AMD K8 core logic. The RS480 also incorporates PCI-Express, and will ship with a DX8.1 IGP solution. All sources indicate that we probably will not see a true DX9 IGP until after RS480 and RS400.

Paired with RS480 and RS400, ATI will also unveil its newest southbridge, SB400. SB400 looks fairly comparable to south bridge solutions from VIA, SiS and NVIDIA. SB400 is compatible with RS480 and RS400. The option to go with 4 SATA devices looks like a good decision on ATI's behalf. There is no LAN support on SB400. SB400 is slated for Azalia Audio support, although we may see an implementation similar to VIA's VT8251 southbridge with both Azalia and AC'97.
