With 2133 memory I get 28GB/s in sandra, while 1600mhz would give me about 20-21GB/s, 1333 about 17GB/s. So you need to mark all of the above being related to core and earlier platforms.

are you saying that bandwidth does or doesnt scale with frequency now?

Here the higher the rated speed - the higher is the bandwidth.

I just said it above

Since the memory controller is on die, there is no northbridge to limit the FSB, so with Sandybridge and above, the faster the RAM is the higher the bandwith. Timing is not important - frequency is.

edit: just noticed this is an old question
