I noticed that some Atom processors use DMI to connect to memory. If I understand correctly, these Atom processors integrated memory control chip inside the processors. But I hope someone can help me clarify the memory accessing speed. For Atom N550 (http://ark.intel.com/Product.aspx?id=50154), DMI is 2.5GT/s. Does it mean the maximal memory accessing rate is 2.5*8=20GB/s if the memory is fast enough? If this is true, it seems this type of Atom processors can support much faster memory. Even DDR3 cannot be this fast.
