1. Developed by Rambus Corporation,* with architecture and protocol designed to achieve high effective bandwidth and single-device upgrade granularity. The narrow, high-performance channel also offers performance and capacity scalability through the use of multiple channels in parallel. Capable of providing up to 1.600 GB/sec bandwidth per channel. The Intel® 850 chipset implements dual RDRAM memory channels to offer 3.2-gigabytes-per-second of peak memory bandwidth. Other Intel chipsets support PC133 SDRAM or DDR SDRAM.
