Are there separate data bus slots in the memory channels on the Intel i7-4600U?

Question

The i7-4600U datasheet says that SA_DQ [63: 0] is used for memory channel A. And SB_DQ [63: 0] is used for memory channel B. Thus, I understand that memory channel A and memory channel B use different processor pins for each own data bus.

Do I understand correctly?

Answer 1

The presence of SA_DQ [63: 0] and SB_DQ [63: 0] pretty much says it all. These are two physical channels.

If you still need a secondary "prof", you can also check the math of this statement in the datasheet

:
      - 21,3 / 1333 /
      - 25,6 / , 1600 /

1333 / ¹ 8 1333 * 8 = 10,664 /.
