SiS R659 core-logic is designed to provide 4-channel RDRAM PC1200 and is able to sport up to 9.60GB/s of peak memory bandwidth – more than enough for present and future Intel Pentium 4 processors with 800MHz Quad Pumped Bus. The chipset also includes architectural enhancements for higher performance through faster response time, a feature SiS calls Advanced HyperStreaming. In total SiS’ R659 supports up to 16GB of memory, while conventional Intel Pentium 4 processors do not address more than 4GB of memory. The R659 North Bridge is to be coupled with the SiS964 I/O controller, which integrates 8 USB 2.0 ports and Serial ATA-150 RAID features.

According to X-bit Labs problably within 4 weeks time Asus will be the first to ship SiS R659-based motherboards. Asus claims that its P4S13G motherboard based on the SiS R659 RDRAM chipset will be 7% faster in Quake III compared to an Intel 875P (Canterwood) chipset. With workstation software it shows about 4% to 12% speed increase according to Asus.
