This should allow manufacturers the option to implement LAN for top performance or for lowest cost. Gigabit or 10/100 Ethernet can be supported by the Northbridge PCI Express bus or the Southbridge PCI bus. PCI Express Gigabit LAN can deliver bi-directional 500MB/s total bandwidth per device. ATI claims that integrated Gigabit LAN offers no performance or cost advantage compared to Gigabit LAN supported by the PCI Express bus.
LAN - The Radeon Express 200 series does not provide integrated LAN in the chipset.
Graphics outputs from both internal and external graphics can be combined in ATI SurroundView. Since the logic core is identical on RX480 and RS480, PCIe x16 support is also available. The graphics core is a modified version of the discrete Radeon X300 core with only two rendering pipelines instead of four. Optional Integrated Graphics - Radeon Express 200G adds ATI's first DirectX 9 integrated graphics, which can be supported by both DVI (digital) and VGA (analog) outputs. The SB450 should be available in early 2005. For instance, an SB450 Southbridge supporting High Definition audio appears on the ATI roadmaps.
The 2-chip design allows ATI to upgrade features just by using a new Southbridge. SATA drives can be combined in RAID 0 and 1 configurations, but RAID 0+1 is not currently supported. The current SB400 south bridge supports 8 USB 2.0 ports, 4 SATA 150 drives, 4 ATA-133 drives, PCI 8-channel AC '97 audio, and up to 5 PCI slots. RS480 adds integrated DX9 graphics with both VGA and DVI outputs. Communication with the CPU is available over a 1GHz (1000MHz) Hyper Transport. This bring the total PCI Express lanes to 22. It is interesting that communication between North and South bridges (RX480/SB400) is handled by 2 additional lanes of PCI Express. The RX480/RS480 Northbridge supports dual or single channel DDR memory, PCI Express x16 for graphics, and up to 4 PCIe x1 slots. Both RX480 and RS480 are currently combined with the SB400 Southbridge. RS480, marketed as Radeon Xpress 200G, adds integrated DX 9 graphics to the 480 core. RX480, called Radeon Xpress 200P, is the discrete Athlon 64 solution for PCI Express graphics cards. RX480 and RS480 are identical except for integrated graphics. ATI believes clearly that there is a better market for AMD A64 solutions right now, which is why they have concentrated on the chipsets for AMD. The current introduction is the A64 chipsets, with the chipsets for Intel targeted for the beginning of 2005. The 480 series is aimed at AMD Athlon 64 and the future 400 series will bring ATI PCI Express to Intel. Radeon Xpress is ATI's name for the new PCI Express chipsets. To understand the current ATI lineup better, you need to take a closer look at how they will be branded and sold. ATI firmly believes that RX480 for Athlon 64 has broken through the performance barrier, bringing competitive or better performance to Athlon 64. Without truly competitive performance as a chipset, there was no real reason for a discrete ATI chipset solution for Intel, although each generation of the ATI chipset for Intel brought more competitive performance. While the previous ATI chipsets brought interesting integrated graphics to the Intel platform, the performance never really threatened Intel's domination of the Pentium 4 chipset market. Previous ATI chipsets have concentrated on integrated graphics for the Intel platform. It is also the first ATI chipset available as a discrete chipset. The RX480/RS480 is the first ATI chipset for AMD. Your driver is up to date - if you have a problem with your driver, you can try to re-install the old version as below.

If your driver isn't working, use the driver having the same OEM with the your laptop/desktop brand name. If you are looking for an update, pickup the latest one. With the different devices, they can have the same driver, it's because they all use the same chip manufacturer.
Below is a list of drivers that may be suitable for your device.
