Two 64-bit independent memory controllers, each with its own physical address space; this provides an opportunity to better utilize the available bandwidth in case of random memory accesses occurring in heavily multi-threaded environments. This approach is in contrast to the previous "interleaved" design, where the two 64-bit data channels were bounded to a single common address space.
