Update: A Samsung spokesperson speaking with TechRadar has confirmed that the Galaxy Note 4 will run on a Samsung Exynos SoC, not a Snapdragon 810. The original story is below.

Samsung has announced a new Galaxy Note 4 variant, and while normally these announcements are pretty boring (faster LTE!), this Note 4 is apparently packing Qualcomm's 2015 flagship SoC: the Snapdragon 810.

Of course the 810 has a slightly faster processor and connectivity options, but the big news is that it finally brings Qualcomm SoCs into the 64-bit era. That brings the processor up to par with Apple's 64-bit chips and helps Qualcomm and its partners keep pace in the marketing wars.

As far as benefits for end users, the biggest change should be the switch from TSMC's 28nm process to a 20nm one. TSMC says the smaller process will use 25 percent less power, and while the majority of power use on a device comes from the screen, every little bit helps.

The device is officially called the "Samsung Galaxy Note 4 LTE-A." Samsung's press release and naming focuses on the addition of a third LTE Carrier Aggregation (CA) Band, which will allow peak download rates of 450Mbps once carriers enable the new feature. Samsung doesn't even mention the Snapdragon 810 by name in its press release, but according to Anandtech, Qualcomm's new SoC is the only chip capable of this new feature.

There's no word on a release date for the Note 4 LTE-A and also no information on what territories it will come to. Usually these "LTE-A" variants from Samsung are limited to Korea, so don't hold your breath for a wider release.
