SiS is the first chipset manufacturer other than Intel to utilize RDRAM. Not only does SiS' R658 chipset support standard PC800 memory, but it has also been validated to operate at PC1066 speeds. Now it seems that even Intel is not ready to forsake the technology. Intel roadmaps indicate that RDRAM will continue offering the highest performance for the Pentium 4, though it remains to be seen if the i850E chipset will see a successor. However, with or without Intel, Rambus reportedly has plans to release PC1200, PC1333 and up to PC1600 right up to 2005. Now that RDRAM is available in 16 and 32-bit configurations, we can also look forward to 64-bit, which will increase overall system bandwidth. DDR-II is just around the corner, so it will be interesting to see which technology prevails.
