  1. Great, a faster core, with a bit of luck A76 will not be considered premium anymore and we can hope to see it land on SBCs next year.

          1. It depends how the SoC is built, I have not tracked down the final truth, but have heard claims one SoC is 12nm Core, 16 nm GPU.
            Time will tell.

        1. Unless someone adds the rest of Chinese manufacturers to the ban and the brits follow their idol…
