Exynos 5433 in the Note 4 is a 64-bit chipset, source code reveals
The Note 4 would be the first 64-bit Android flagship, or at least that will go for its reincarnation with Samsung's own Exynos 5433 chipset. Just as suspected, despite that the naming scheme still puts it in the Exynos 5x family, the newest Samsung chipset is not a Cortex-A15/A7 affair, but rather takes the next step in ARM's mobile architecture, by incorporating the A57/A53 configuration, as its source code reveals, which ARM touts as capable of 64-bit computing.

In all likeliness, the Note 4 sports precisely the latest and greatest Exynos 5433, despite that Samsung hasn't officially revealed the silicon, and just writes "1.9 GHz octa-core processor" in its specs. It is therefore shaping up to be the first Android handset with flagship specs that will cross over into the 64-bit barrier, at least on paper. As for the GPU, it is probably ARM's latest Mali T760, clocked at the astounding 700MHz, which would add to the benchmark-busting performance of the Note 4 equipped with said Exynos.

Why isn't Samsung advertising that fact, one would ask? Well, before Android L ships out, and there are apps that take any advantage of the 64-bit architecture, about the only tangible improvement one could do is equip the 64-bit phones and tablets with more than 3 GB of RAM, and there's not exactly a pressing need for that at the moment. With that being said, Samsung has opted to run the chipset in a regular 32-bit mode, as it will ship with KitKat out of the box, so no need to optimize for something without possible application at the moment. In any case, the Exynos-laden Note 4 could at least be futureproof, and with its Quad HD display and 64-bit architecture, it might remain so for two upgrade cycles now, instead of the typical one.

It beats even the Snapdragon 805 quite comfortably http://browser.primatelabs.com/geekbench3/compare/752193?baseline=775311

Oh but wait the snapdragon completely destroys the exynos version in memory performance :o that's bad

I think Samsung deliberately reduced the memory speed so it can give similar performance to S805, reference big.LITTLE A53/A57 have same memory bandwidth with S805 at 25.6 GB/s and ideally supposed to run at 64-bit dual channel 1600 MHz, but you can see Samsung put them at 32-bit dual channel 825 MHz.

I'm just for a release date. Hopefully the Exynos LTE modems play nice with AT&T.

Please read source article properly or visit the XDA threadhttp://forum.xda-developers.com/note-4/general/to-snapdragon-805-to-exynos-5433-t2868247 These articles provide very less or misleading information.

So the Galaxy Alpha is 64-bit too ?

16. PapaSmurf

No, it's 32-bit.

Unfortunately no The Alpha has the 32-bit 5430, not the 64-bit 5433

so Samsung doesnt want to advertise 64bit to avoid a marketing gimmick unlike apple...

29. slh163

Posts: 140; Member since: May 19, 2014

that's what it look like, because apple have never talked about how consumers can take advantage of that 64bit

In my view consumers cannot take advantage of apple's 64bit bcoz they are still using 1gb ram which makes it marginal over 32bit

I don't care about benchmarks Exynos variants are always the ones that lag the most when compared to Samsung's SD variants

The Exynos 5433 destroys the SD 805 in it's 32-bit factor wait till Android L update comes to this beast (that's not far away) the processor that you can compare it with the 5433 is the SD 810 or the Tegra K1 and the results will be very similar.

You think so? You think that a 64 bit octo-core cpu lag?!! Even with 4 Cortex A57 cores clocked at 1.9GHz and even with graphics Mali T760 at 700MHz with problably 16 cores, that is +/- 342 gigaflops, and still you think that the performance in your opinion it's worse and inferior to Snapdragon 805? You are f**ked of your head.
