Samsung announced two new mobile SoCs at MWC today. The first is an update to the Exynos 5 Octa with the new Exynos 5422. The 5422 is a mild update to the 5420, which was found in some international variants of the Galaxy Note 3. The new SoC is still built on a 28nm process at Samsung, but enjoys much higher frequencies on both the Cortex A7 and A15 clusters. The two clusters can run their cores at up to 1.5GHz and 2.1GHz, respectively. The 5422 supports HMP (Heterogeneous Multi-Processing), and Samsung LSI tells us that unlike the 5420 we may actually see this one used with HMP enabled. HMP refers to the ability for the OS to use and schedule threads on all 8...
