Galaxy Note 4 Powered by 64-bit Exynos 5433 Benchmarked, Only Beat by One Other Chipset | Droid Life. How does a 64 bit octa-core processor that will be the fastest chipset in the universe sound? In a couple of weeks, Samsung will announce the Galaxy Note 4, and it promises to be wonderful. 3 Gigabytes of RAM and speed that leaves other smartphones in the dust, with 3D rendering that will rival anything out there, together with KitKat and the best screen in the business, all augur well for the new flagship of the Samsung line. I will use an upgrade to get one as soon as I can, just to be able to say that I have the fastest phone on the planet. At least, for a few months anyway. I know, boys and their toys. Get over it.
