    Kal-El uses Cortex-A9 cores. I think you meant Tegra 4 (Wayne).

    Also, I find this interesting since Kal-El uses a similar approach, albeit with a lower clocked 5th A9 core.

    Are these SoC named after Superman and Batman? Kal-el, and Bruce Wayne? If so, that's pretty cool. I always knew the codename of Tegra 3, but just now it hit me. I know, I know, shame on me.

    And yeah, Tegra 3 uses five cortex A9 cores, with the fifth one lower clocked. I believe the A15 uses a much lower semiconductor than the A9, possibly the same as the A7 (28nm); the A9 uses a 40nm semiconductor, which is more efficient than the A8, but presumably still not as fast/efficient as the A7 and the future A15. So it's definitely Tegra 4 that uses A15.
