The VIA KT400A takes the AMD Athlon™ XP processor to the summit of system performance with a FastStream64™ memory controller technology, 333MHz Front Side Bus, AGP 8X Graphics, 6-Channel Audio, Serial ATA, ATA-133, USB 2.0 and 8X V-Link chip interconnect.

Building on the success of seven generations of market leading Chipsets for the AMD Athlon™ XP processor, the VIA KT400A boasts a complete set of today’s cutting-edge features combined with VIA’s ultra efficient FastStream64™ memory controller technology, delivering performance equivalent to or superior than 128-bit solutions. DDR400 memory support, offering 20% more memory bandwidth to the CPU than DDR333, and the fast 200/266/333MHz processor bus, unleash the full power of AMD Athlon™ XP processors, enabling stunning performance across the full spectrum of applications.

In addition, the VIA KT400A supports the very latest I/O technologies including AGP 8X deriving maximum performance from the most powerful graphics processors. 6-Channel surround sound AC’97 audio completes the audio-visual experience offering an integrated high quality sound solution when listening to mp3s, watching movies, or playing the latest games. The KT400A North Bridge is connected to a VT8237R Plus South Bridge through the fast 8X V-link connection at 533MB/s. With two channel native support for Serial ATA in the South Bridge supplying 150MB/s of bandwidth, as well as up to Eight USB 2.0 ports the VT8237R Plus offers the highest possible peripheral performance for professional and home users.

FastStream64 Technology: VIA FastStream64™ Technology uses an expanded array of prefetch buffers to reduce latency in the memory controller, extending performance at a lower transistor cost than dual channel implementations. With a 200/266/333MHz processor bus and supporting DDR200/266/333/400 memory, the VIA KT400A provides lightning fast access to system memory and can reach a peak bandwidth of 3.2GB/sec, 25% greater than the KT400, enabling the full performance potential of the fastest AMD Athlon™ XP processors to be harnessed.
