    The best part of following the mailing list of compilers is know ahead of time what will come for smartphones processors

      Smart phones are nice but what i really wish for is an embedded board that supports more RAM and Linux well. A Raspberry PI like board with 4 - 8 GB of RAM would be very useful. This especially with the rapid advances in performance for these SoC.

        Time to market plays a big role here, Nintendo Switch went with a maxwell GPU instead of pascal because the time involved in developing the product, so when it finally launches, it might appear as outdated

          They are not "big.LITTLE" cores, they are dynamIQ cores. This is not just a nit-picking distinction.

          big.LITTLE came with some decisions that ensured it was going to be much slower than it needed to be (like big and LITTLE cores living in different clusters, so expensive to transition between them). Apple did not follow this model, allowing for much tighter coupling between a big and a LITTLE core and (as far as we can tell) hardware control, at least under some conditions, of power states. dynamIQ (later than it should have been, but better late than never) follows the same model, allowing much more flexibility how tightly big and LITTLE cores are coupled, and HW control of power states.
