So far all mainboards for AMD Athlon 64 family of processors have been based only on chipsets from VIA or NVIDIA. However, there are more chipset companies, who announced support for AMD64 platform, such as SiS, ALi and ATI. ALi and ATI still have announced nothing, while SiS755 has not only been announced, but has managed to reach retail!
SiS755 is not just yet another combination of AGP 8x tunnel with feature-rich I/O controller, but a highly-efficient chipset with HyperStreaming architecture – a technology that executes data transactions more efficiently compared to other core-logic products. According to X-bit labs recent benchmarks, SiS755 proves to be substantially faster its rivals in a number of applications.
The first mainboard based on SiS755 that reached retail market – ECS-755 – allows installation of Socket 754 processors, provides end-users 2 DIMM slots for up to 2GB of PC3200 DDR SDRAM, has an AGP 8x slot, 5 PCI slots, 2-channel ATA-33/66/100/133 and 2 Serial ATA-150 ports with RAID support. The mainboard is also equipped with 10/100Mb/s Ethernet controller, offers 6-channel AC'97 audio, USB 2.0 ports as well as some other capabilities.
The mainboard is quoted starting from $80, according to PriceWatch search-engine.
