This chipset supports Pentium 4 with 800,533 or 400MHz FSB and Hyper-Threading. The memory controller supports up to 4 DIMMs with DDR400 or DDR333 memory in Dual or Single channel. It also has 8x AGP ofcourse.
The Southbridge bundled with the SiS655TX is the SiS964. It supports eight USB 2.0 ports, Serial ATA, integrated LAN, AC'97 integrated sound, ...
Advanced HyperStreaming™ Engine technology, delivering even higher overall performance in comparison with HSE technology, supports the SiS655TX to offer the advanced intelligent data processing that maintains the best resource utilization across multiple operating environments. Advanced Stream Forwarding Acceleration technology breaks through the bottleneck of the traditional PC architecture wherein data transfer is limited by the need for synchronized streams. Hence, a significant decrease in time for signal transmission processing and latency is achieved to simultaneously improve both computer performance and efficiency.
Motherboards based on the SiS655TX are expected in November.
