| 7th Generation Socket A Chipset From VIA VIA FastStream64 Technology Maximizes Performance with the new AMD Athlon XP 3000+ CPU, and leaves nForce2 trailing AGP 8X with VIA Hyperion 4in1 Drivers For Maximum Frame Rates in Doom ‘III’ Generation Games First to Market Native Serial ATA support in the VT8237 South Bridge VIA TidalWave Onboard Audio For Surround Gaming DualDDR: Cost Without Benefit AMD 333MHz FSB is maxed out at 2.7GB/s, equivalent to the maximum theoretical bandwidth in a single channel DDR333 configuration Dual DDR configurations for the AMD Athlon™ XP are overkill and needlessly raise the cost of the platform The key to performance is the efficiency of the North Bridge memory controller and CPU interface FastStream64™ Technology FastStream64™ Technology enables the single channel 64-bit memory controller of the KT400A to out perform the Nforce2 Chipset in 128-bit mode 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 KT400A is designed to maximize performance in both synchronous (DDR333/333MHz FSB) & asynchronous (DDR400/333MHz FSB) modes KT400A North Bridge Summary Leading Edge Performance Features 200/266/333MHz Front Side Bus Ultra-fast FastStream64 Memory Controller with 200/266/333/400MHz system bus Support for up to 4GB High-Speed DDR200/266/333/400 SDRAM 8X V-Link Architecture - Peak bandwidth of 533MB/s AGP 8X with 2.1GB/s of dedicated bandwidth for the GPU Supports full range of Socket A 462-pin AMD Athlon XP processors including the new ‘Barton’ core CPU’s VIA TidalWave Onboard Audio Full support for the latest surround sound games: Don’t get taken from behind VT1616 Codec solution in combination with VT8235/8237 SB with Sensaura Drivers Higher Quality and Fidelity Than Nforce2 mainboards featuring inferior codec solutions DualMax -- hardware downmixing technology CoolAmp – reduced heat for consistent performance Serial ATA - Native Support in Q2 First to market native Serial ATA support in the VT8237 will finally realise performance potential of 150MB/s interface Bypasses PCI Bus and flies straight to the 533MB/s 8X V-link Chip Interconnect superior performance in the most data intensive applications VT6420 - Full specs here 1st Combined SATA, PATA & RAID Controller Supports 2 channels for up to 4 SATA Devices Supports 1 channel for up to 2 PATA Devices Supports RAID Levels 0,2,0+1 & JBOD SATAlite Interface allowing 2 additional channels with external phy Tiny 15mm BGA package VT8237 Supports up to 4 SATA Devices Supports up to PATA Devices Supports 8 X USB 2.0 Supports 8X (533MB/s) & Ultra (1.06GB/s) V-Link Chip Interconnect Pin compatible with VT8235CE for simple mainboard upgrade VIA Modular Architecture Platform V-MAP - Pin-to-Pin Compatible South Bridge options - Drop-in North Bridge replacement for KT400 Seamless product transitions on a single motherboard platform - Faster Time to Market - Lower Product Development, Validation, and Production costs KT400A + VT8235CE VIA FastStream Technology DDR266/333/400 Support 333MHz FSB AGP 8X 8X V-Link USB 2.0 ATA-133 10/100 Fast Ethernet 6-ch. AC’97 Audio VT8235 High Degree of Integration 8X V-Link USB 2.0 VIA Ethernet MAC ATA 133 6 Channel Audio MC’97 Modem LPC PCI Controller KT400A + VT8237 VIA FastStream Technology DDR266/333/400 Support 333MHz FSB AGP 8X 8X V-Link USB 2.0 SATA ATA-133 10/100 Fast Ethernet 6-ch. AC’97 Audio VT8237 Connectivity in 2003 Ultra V-Link 8 USB 2.0 Ports VIA Ethernet MAC SATA/PATA 133 6 Channel Audio MC’97 Modem LPC PCI Controller Unified Performance Drivers Maximum System Performance Maximum Compatibility and Stability Regular Updates Downloads and support at www.viaarena.com Reducing Support Costs for VIA and VIA motherboard customers 3D Graphics Performance Second to None (source VIA) The Fastest Gaming Platform (source VIA) Jedi Knight II (source VIA) Great Performance in The Toughest Benchmarks (source VIA) Content Creation Performance (source VIA) |
