| VIA Apollo P4X400
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 new 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.
