Recently, the AnTuTu benchmarking database was populated with not one, but two alleged Note 4 models, codenamed SM-N910S, and SM-N910C. The "S" apparently stands for the version of the handset with a Qualcomm Snapdragon 805 processor, but the "C" model is where it gets interesting. It allegedly depicts a Note 4 with the rumored powerful Exynos 5433 processor that is yet to make a cameo in a Samsung press release.
Now, that new Exynos processor is said to be an octa-core endeavor with Cortex-A57 and Cortex-A53 combination of processor cores, clocked at 1.3 GHz maximums. These are both ARM's first 64-bit processor cores, combining frugal power consumption with screeching fast performance. The GPU was listed as ARM Mali-T760, which means that the Note 4 should perform equally well in the graphics department regardless of whether it comes with Snapdragon 805 or the Exynos 5433.
In fact, Samsung poured extra water in the rumor mill about its first 64-bit processor, by teasing on Twitter an Exynos announcement that is due today, as you can see in the picture above. We'll keep our eyes peeled and ears open, and will let you know all the juicy details about the eventual Exynos 5433 that will likely be in the Note 4, as soon as it hits the tape.
