Samsung's foray into all matters mobile has been one of great consequences, and according to the company, its new Exynos 5420 Octa SoC will stay true to that legacy. The Samsung Exynos blog has outed a more in-depth look at what the new and improved SoC will bring to the table, and we've got to admit that its got us anxious to put the new silicon to use ASAP.
But performance has always come at a price – battery life. Which is what ARM's big.LITTLE platform and the Exynos 5420 Octa are all about – power, only when and if needed. But make no mistake, the Exynos 5420 doesn't trade performance for longevity – the new chipset promises “more than twice” the graphical capabilities over its predecessor (Exynos 5410 Octa), thanks to its six-core Mali-T628 GPU. Apart from coming with support for OpenGL ES 3.0, the new Mali GPU also features GPU Computing functionality, which will give the CPU a hand with certain tasks which can be performed both faster and more efficiently by the GPU.
GPU Computing functionality will further add support for features such as video and image stabilization and editing, facial recognition and more. The Exynos 5420 Octa also supports MIC, or Mobile Image Compression, which will help lower system power required to bring photos to your screen from memory, meaning photo-editing won't drain as much battery as before.
Samsung claims that energy efficiency has been improved by some 70% with the new Exynos, and this apparently comes with no drawbacks – CPU performance is said to have increased a fifth, compared to the Exynos 5410. Of course, we're yet to get our hands on a commercially available device sporting the new silicon, but we've seen some pretty conclusive evidence that Sammy isn't taking us for a spin.
