    Apple lists the memory speed for the rMBP as 1866 MHz, but for the MBA it is 1600 MHz. Previously both were 1600 MHz.

    Anyone know what the memory speed will be for the 12" rMBA?

    I don't, but those speeds don't really matter anyway. That doesn't tell you how many cycles it takes to access the memory so you could easily have faster-clocked memory that performs worse than slower-clocked memory.

    Not that memory speed matters much these days anyway now that CPUs have multi-megabyte L2/L3 caches on-die.
