Samsung announced the 8-core Exynos 5 Octa Processor during CES & announced that, it only seems logical that the company will include that processor in at least some of their 2013 devices. Notably, the higher-end devices such as the Galaxy Note, which presumably will be released as the Galaxy Note III later in the year. Samsung has yet to confirm the details (or the existence) of the Note III, however some reports have begun to surface with talk of specs.

Aside from display size and processor, that is where the specs have stopped for the Note III. The interesting part here, while the Note II already has stellar battery life, the battery life on the Note III could be even better. The Exynos 5 Octa will have a total of 8-Cores broken down as four Cortex-A15 processors and four Cortex-A7 cores. This means the A15 cores will handle processing-intense tasks and the A7 cores handling the lighter workloads.
According to Samsung, this means upto 70 percent higher energy efficiency as compared to the previous quad-core Exynos. Bottom line here, assuming things play out as they appear — it is looking like Samsung will be able to make a nice jump from the Note II to Note III with improvements to not only the processor and battery life, but also have it arrive with a much larger display. We just have to wonder, what is that point where smartphones and tablets will find middle ground.
