Samsung sheds some more light on the Exynos 5420 Octa: more power and longer battery life

Samsung's foray into all mattersmobile has been one of great consequences, and according to thecompany, itsnew Exynos 5420 Octa SoC will stay true to that legacy. TheSamsung Exynos blog has outed a more in-depth look at what the newand improved SoC will bring to the table, and we've got to admit thatits got us anxious to put the new silicon to use ASAP.

But performance has always come at aprice – battery life. Which is what ARM's big.LITTLE platform andthe Exynos 5420 Octa are all about – power, only whenand if needed. But make no mistake, the Exynos 5420 doesn't tradeperformance for longevity – the new chipset promises “more thantwice” the graphical capabilities over its predecessor(Exynos 5410 Octa), thanks to its six-core Mali-T628 GPU. Apart fromcoming with support for OpenGL ES 3.0, the new Mali GPU also featuresGPU Computing functionality, which will give the CPU a hand withcertain tasks which can be performed both faster and more efficientlyby the GPU.

GPU Computing functionality willfurther add support for features such as video and imagestabilization and editing, facial recognition and more. The Exynos5420 Octa also supports MIC, or Mobile Image Compression, which willhelp lower system power required to bring photos to your screen frommemory, meaning photo-editing won't drain as much battery as before.

Samsung claims that energy efficiencyhas been improved by some 70% with the new Exynos, and thisapparently comes with no drawbacks – CPU performance is said tohave increased a fifth, compared to the Exynos 5410. Of course, we'reyet to get our hands on a commercially available device sporting thenew silicon, but we'veseen some pretty conclusive evidence that Sammy isn't taking us for aspin.
