kt333The VIA Apollo KT333 is an efficient, cost-effective, flexible chipset solution for systems based on the AMD Athlon™ XP and Duron™ Socket A processors, across a full spectrum of applications. With a 64-bit DDR333 SDRAM memory controller and a 333/266/200 MHZ front side bus, the KT400 offers efficient system performance. An AGP 4X controller enables connection to external graphics cards, and an 8X V-link chip interconnect offers 266MB/s of bandwidth between North and South Bridge.kt333_main

The VIA KT333 can be paired with a choice of VT8233/VT8233A/VT8233C South Bridges, which are connected through the chipset’s V-Link Hub Architecture. Other key features include support for ATA-100 (ATA-133 in the VT8233A), integrated AC-97 six- channel advanced audio, six USB ports, LPC bus, integrated 10/100Mbps Ethernet and Home PNA, and MC-97 modem.

Benefits of VIA KT333

Performance: With a 333/266/200 MHz processor bus, 64-bit DDR333 SDRAM memory controller, 266MB/s bus between the north and south bridges, a peak bandwidth of 2.7GB/sec, and support for AGP 4X, the VIA Apollo KT333 provides efficient performance for AMD Athlon™ XP and Duron™ processors-based systems.

VIA Stability and Reliability: VIA Chipset Platforms offer a balance of reliability and flexibility derived from using proven, modular components and evolutionary design principles.
