The official naming is also a bit confusing. Originally the naming was PC200 for DDR-SDRAM that operates at 100 MHz memory bus and PC266 for the 133 MHz bus. After Rambus however used PC600, PC700 and PC800 for their RDRAM modules, which sounds a lot faster than PC200 or PC266 although it isn't, the memory industry came up with 'PC1600' and 'PC2100' instead. While PC200 and PC266 are only using the effective clock of the data transfer for their numbering, PC1600 and PC2100 use the actual peak data transfer rate in MB/s. Thus PC200 is the same as PC1600 (64 bit * 2 * 100 MHz = 1600 MB/s) and PC266 is equal to PC 2100 (64 bit * 2 * 133 MHz = 2133 MB/s).
