New Samsung Exynos 5 Octa: 20% more CPU power, twice the graphic capabilities
Last week, Samsung told us to expect the introduction soon of an evolved, enhanced version of its Exynos 5 Octa-core processor. Sure enough, on Monday the latest Exynos 5 Octa-core chip was unveiled. The new Samsung Exynos 5420 will include a six-core ARM Mali-T628 GPU that handles 3D graphics twice as fast as the previous Exynos 5 Octa-core. It is a return to the ARM based Mali GPU following the use of a PowerVR chip in the Exynos 5420 (see the chart below).

Turning to the CPU, the eight cores are made up of four ARM Cortex-A15 processors clocked at 1.8GHz with four additional Cortex-A7 cores at 1.3 GHz. With the big.LITTLE set-up, only one set of four cores is active at a time. CPU processing capabilities are improved by 20% over the predecessor chip.


Total system power is lowered when multimedia content is brought from memory to display panel thanks to the multiple image compression (MIC) IP block on the chip. This maximizes the battery life of a device with a high-resolution display, even those with a resolution as high as 2500 x 1600 (WQXGA). Battery life is conserved even when browsing or using multimedia rich apps, or other applications that require the screen to be frequently refreshed.

The new Samsung Exynos 5420 is being sampled by customers and will be mass produced starting next month. There is speculation that the international version of the Samsung Galaxy Note III will feature this silicon under the hood.
