Samsung couldn't help itself last week when it teased a new Exynos 5 Octa system on a chip, and now it's dishing out the full details. The fresh 5420 variant of the SoC is based on Mali-T628 MP6 silicon, packs a quartet of ARM Cortex-A15 cores running at 1.8GHz and four 1.3GHz Cortex-A7s in an ARM big.LITTLE configuration. Seoul claims that the package packs 20 percent more CPU processing punch, and has two times greater 3D graphics power than its predecessor. Dual-channel LPDDR3 at 933MHz gives the processor a screaming memory bandwidth of 14.9 GBps, which lends it full HD WiFi display support. Baked inside is an image compression solution that makes for energy efficient multimedia loading, and squeezes out more hours of use with high-res displays. There's no word on which devices might use the new SoCs, but the chips are already being sampled by Samsung's customers, and mass-production is slated for August.
