VPX-64 64bit/66MHz PCI Controller
The VPX-64 64bit PCI Controller (model number VT8101) is a companion chip that allows existing VIA chipsets to support high-bandwidth 64bit PCI in both 33MHz and 66MHz modes. VPX-64 enables VIA Apollo chipsets to offer up to 533MB/s of PCI bandwidth for high end peripherals like Gigabit Ethernet, Fibre Channel and Ultra SCSI/320 and is perfect for implementation in server systems based on the VIA Apollo P4X266E. VPX-64 also supports up to six traditional 32bit/33MHz PCI devices, allowing VPX-64 equipped system designs to support no less than 10 PCI devices, and up to 12 in total. VPX-64 is available in a 27x27mm, 265 pin PGA package. VPX-64 interfaces directly to the dual mode AGP/XIP port present in existing V-MAP compatible chipsets.

High-Speed V-Link Hub Architecture
The VIA Apollo P4X266E takes advantage of VIA's high performance V-Link Hub Architecture, which provides a dedicated 266MB/s bus between the North and South Bridge. Less advanced chipsets use the 132MB/s PCI bus as a link, which must be shared with all PCI peripherals. V-Link greatly improves data transfer rates when high-speed interconnect technologies such as USB2.0, IEEE1394, and ATA/133 are implemented in a single system.

V-MAP
The VIA Apollo P4X266E is part of the family of VIA Modular Architecture Platforms (V-MAP). As a modular solution, the North and South Bridge of VIA Apollo P4X266E are completely pin compatible with current and future products. The VT8753A North Bridge of P4X266E is pin compatible with the VT8753 of P4X266, and the VT8751 of P4M266. Additionally, VT8753A can interface with four separate pin-compatible South Bridges, including the new VIA VT8235 with integrated USB 2.0 support as well as the VT8233 offering VIA Ethernet MAC, the VT8233C featuring 3Com Ethernet MAC, and the VT8233A supporting the new ATA/133 drive standard. With this wide range of pin-compatible products, up to six distinct chipsets are possible for Intel? Pentium? 4 processors while using the same motherboard design.

Performance Driven Design
Using the highly efficient memory controller of the renowned VIA Apollo KT266A, the VIA Apollo P4X266E offers exceptionally high memory performance. This is accomplished through improved timings and deepened queues. Supporting up to 4GB of DDR200 or DDR266 memory, the VIA Apollo P4X266E provides lightning fast access to system memory. Moreover, the VIA Apollo P4X266E offers a highly developed AGP4X interface, ensuring the highest possible graphics performance with a myriad of AGP4X graphics accelerators.

Enhanced Processor Bus
The VIA Apollo P4X266E features an enhanced processor bus interface that more efficiently takes advantage of the quad pumped bus of the Intel? Pentium? 4 processor. Now, up to 12 instructions can be queued in the processor bus interface, allowing the high speed 533MHz bus of current Pentium? 4 processors to run at optimal efficiency. This also reduces latency between the processor and other peripherals and devices, which improves overall system operation. The VIA Apollo P4X266E also offers support for higher bus speeds, allowing seamless upgradeability to possible future processors.
