Samsung Exynos 5 OCTA 5422 and Exynos 5 HEXA 5260

Samsung at Mobile World Congress presented  an update of its octa-core Exynos 5420, called the Exynos 5422, which can be operated with all eight cores and offers a higher clock rate and a new hexa-core, Exynos 5 Hexa 5260, with two and four core ARM Cortex A15 and A7 respectively.

The Exynos 5 Octa 5422, whose base is the same as 5420 is made with 28 nm HK + MG type manufacturing process, combined with the ARM Mali T-728 MP6 GPU. Both the A15 A7 are working at higher frequencies, the first at 2.1GHz instead of 1.8 GHz and the second at 1.5 GHz instead of 1.3 GHz It also include the approval function Heterogeneous Multi-Processing, which will allow the software to request the activation also of all eight cores simultaneously in the case of heavy task. Unchanged is the support for the RAM, which is kind of dual channel 32-bit LPDDR3-1866. The new Exynos 5422 is faste, also built with multimedia in mind, it is capable of supporting WQHD (2560 x 1440 pixels) and WQXGA (2560 x 1600 pixels) resolutions, in addition to an output 4k.

The Exynos 5 Hexa 5260 is entirely new, it offers an asymmetric six-core architecture, with two ARM Cortex A15 cores for programs demanding more power, but always accompanied by four A7 cores for greater energy savings .The first run at a clock rate of 1.7 GHz, the other four at 1.3 GHz However, unlike Exynos 5422 there is no way for them to work well together. The GPU is an ARM Mali T-624  GP. The RAM is finally supported by 32-bit type LPDDR3-1600, although always dual channel.

In this way, therefore, the Exynos 5260 is configured as a less powerful and more fuel efficient than the 5422. Despite the fact the lower power Exynos 5 Hexa 5260 supports resolutions up to 2560 x 1600 pixels and video playback up to 1080p @ 60 FPS, the Samsung Exynos 5260 is already used in the LTE version of the Galaxy Note 3 Neo.
