In most electronics nowadays performance is king and the more bit-crunching power you can put out, the better. This is not exactly the case with smartphones, though, where power efficiency is equally if not more important. This being said, however, no true power-user can deny that having more power under the hood is always better and in the mobile realm Samsung currently has the lead, by a long margin. The latest Exynos 7420 chipset, found in the Galaxy S6 and S6 edge is way ahead of its competition in sheer performance and according to a new rumor, the Korean giant has something even better in store. According to the latest reports the next Exynos chip will be powered by custom cores, rather than the stock Cortex A72 silicon. The SoC is allegedly codenamed "Mongoose" and will be clocked at 2.3 GHz. The rumor also cites a single-core Geekbench score, which is impressive, to say the least.

Furthermore, even if this information is true and Samsung powered the Galaxy Note 5 or the next Galaxy S device with the new entirely custom chip, raw-power does not necessarily translate into real-world performance and a lot of other factors have to be considered as well, most notably - battery life.
