Fusing the unequalled bandwidth of AGP 8X with the Intel® Pentium® 4 processor, the VIA Apollo P4X400 with 533MHz processor bus, DDR333 , ATA-133, USB 2.0 and 8X V-Link chip interconnect, is a new paradigm in total system performance.
Building on the success of the VIA Apollo P4X266, the first DDR266 SDRAM chipset for the Intel® Pentium® 4 processor, the VIA Apollo P4X400 is the most feature rich and powerful chipset ever produced. DDR333 memory support, offering 20% more memory bandwidth to the CPU, and the ultra fast 400/533MHz processor bus unleash the full power of today’s and tomorrow’s Intel® Pentium® 4 processors, enabling stunning performance across the full spectrum of applications.
In addition, the VIA Apollo P4X400 supports the very latest I/O technologies including AGP 8X deriving maximum performance from the most powerful graphics cards, and new 8X V-link chip interconnect with 533MB/s of bandwidth between North and South Bridge enabling the processor to exploit the full potential of peripheral devices.
The VIA VT8235 South Bridge also features first to market innovations including support for 6 USB 2.0 ports for peripheral connectivity 40 times faster than USB 1.1, and ATA-133 support, the fastest IDE interface available, making total system performance a reality. Additional features include integrated into the South Bridge include VIA MAC for 10/100Mbps Ethernet, integrated PCI support, 6 Channel Surround Sound AC-97 audio and MC-97 modem.
Benefits of VIA P4X400
Ultra Powerful Performance: The VIA Apollo P4X400 features the world’s fastest single channel memory controller, designed for exceptionally high performance. With a 400MHz/533MHz processor bus and supporting DDR200/266/333 memory, the VIA Apollo P4X400 provides lightning fast access to system memory and can reach a peak bandwidth of 2.7 GB/sec, 20% greater than the P4X266A, enabling the full performance potential of the fastest Intel® Pentium® 4 processors to be harnessed.
Ultimate Connectivity: The VT8235 South Bridge with 8X V-link, USB 2.0 and ATA-133 provides the most advanced connectivity features to ensure the ultra fast processor and memory are not restricted by peripheral bottlenecks. USB 2.0 and ATA-133 high-speed transfer technologies are essential for today’s bandwidth-hungry peripherals, and greatly enhance the performance of demanding applications including interactive gaming and digital photography.
