Answer 2

RAM type Theoretical max. bandwidth
SDRAM 100 MHz 100 MHz X 64 bit= 800 MB/sec
SDRAM 133 MHz 133 MHz X 64 bit= 1064 MB/sec
DDRAM 200 MHz 2 X 100 MHz X 64 bit= 1600 MB/sec
DDRAM 266 MHz 2 X 133 MHz X 64 bit= 2128 MB/sec
DDRAM 366 MHz 2 X 166 MHz X 64 bit= 2656 MB/sec
RDRAM 600 MHz 600 MHz X 16 bit= 1200 MB/sec
RDRAM 700 MHz 700 MHz X 16 bit= 1400 MB/sec
RDRAM 800 MHz 800 MHz X 16 bit= 1600 MB/sec
