The Galaxy Note 4 will have two versions: one with Snapdragon 805 model N910S , and another with Exynos 5433 model N910C . AnTuTu results were found in both versions, which shows that the model with Exynos got a higher score.
The new Exynos is Samsung’s first SoC with support for 64-bit , formed by four cores Cortex-A53 and four cores Cortex-A57 . These new cores make use of the instructions implemented in architecture ARMv8-A , the same used in the cores Cyclones Processor A7 Apple .
While the 805 is still a Snapdragon processor 32-bit using the instructions in architecture ARMv7 . With this, the Exynos already takes the advantage of a more advanced architecture with support for new instructions that add more performance to the system.
at these images above, you can see that the new Exynos comes near the Tegra K1 . It could even be equal or superior, but Samsung decided to stop the performance of Exynos 5433, to disable some cores of the GPU, so that it would not be much higher than the model with Snapdragon. Much of this difference the new Mali-T760 GPU that displays 326GFlops graphical power , is due while Adreno 420 has only 224GFlops .
It is good to remember that Android 4.4 is used here KitKat that does not use the new instructions ARMv8-A architecture. With Android L , this difference between the models may be higher, since the little robot system will be fully compatible with 64-bit hardware.
