pc2700 en pc 3200 enz. geeft de bandbreedte van de geheugen module weer

DDR Memory Bandwidth
The calculations below illustrate how the peak bandwidth for DDR memory modules is calculated.
Peak Bandwidth = (Memory Bus Width) x (Data Rate)
where Data Rate = (Memory Bus Speed x Operations/Clock Cycle)
Each DIMM module is 64 bits wide, or 8 Bytes wide (each byte = 8 bits).
Peak bandwidth for PC1600 DIMMs
(8 Bytes) x (200 MHz Data Rate) = 1,600 MB/second
or 1.6 GB/second.
Peak bandwidth for PC2100 DIMMs
(8 Bytes) x (266 MHz Data Rate) = 2,128 MB/second
which is rounded to 2,100 MB/second or 2.1 GB/second.
Peak bandwidth for PC2700 DIMMs
(8 Bytes) x (333 MHz Data Rate) = 2,664 MB/second
or 2.7 GB/second.
Peak bandwidth for PC3200 DIMMs
(8 Bytes) x (400 MHz Data Rate) = 3,200 MB/second
or 3.2 GB/second.
