Later this year, Intel plans to drop support for Direct Rambus DRAM memory
chipsets in new computer products. New chipsets supporting double data rate
(DDR memory) will replace the last RDRAMs used in Xeon workstations, and Intel's
new generation of workstation chipsets will support only SDRAM and DDR.
At the end of February, Intel announced its new E7500 chipset, which not only
uses DDR SDRAM, but dual channel DDR SDRAM (see http://www.ebnews.com/story/OEG20020226S0040).
