    If the cause of the memory performance issue is in the SoC, I think it's in the SoC's 'uncore' (memory controller) rather than its core.


    I'd like to see some bandwidth figures for the T10xx CPUs when interfaced with DDR4.
    The DDR3 controller used with other e5500 and e6500 cored CPUs does seem to be the issue.


    I thought the memory bandwidth and speed for the X1000's PA6T, was one of its few advantages, when compared to the older Apple G4 & G5 computers? Or is the PA6T an exception for e6500 cored CPU's, when it comes to memory bandwidth?

    It's probably that I'm not paying attention to this discussion, so I have made an incorrect assumption (again).

    Edit: I probably should have changed "memory bandwidth" above, to read/write speed to RAM.
