Exynos 5420 Octa shown utilizing all of its eight cores simultaneously

Samsung's in-house foray into the semiconductor's industry in the form of its Exynos SoCs has, undeniably, managed to etch a spot for itself. But though we see it in some high end, modern devices, there are those of us who have been pondering whether Samsung's sheer size has played an integral role in its continued survival, more so than its own merits. And while those sure are abundant, an overarching concern has been on the agenda for the past year as far as the last two models of the SoC are concerned. Namely, while ARM's big.LITTLE platform sounds great on paper, the Exynos 5410 and 5420 have been unable to take advantage of all eight Cortex cores simultaneously.

Until the other day, when Samsung announced that the Exynos 5420 Octa will finally support Heterogeneous Multi-Processing (HMP), or said otherwise – it will finally allow the chipset to take advantage of all eight cores' computing muscle at the same time.

Deciding to visually showcase what HMP means, ARM, on whose platform the Exynos is based, has released a trio of short clips exemplifying the behavior of the chipset under several real world scenarios, and has also demoed the usefulness of GPU Compute. As you're about to witness for yourself, the four smaller, Cortex-A7 cores are capable enough to handle most of the typical tasks a user goes through on his smartphone, but they will be now backed by the other four, more powerful Cortex-A15 cores whenever 'typical' just doesn't cut it.
