Samsung Exynos 7 Octa announced
At first glance the new Exynos 7 name-tag suggests an entirely new processor, but closer inspection reveals that the chip is very similar, if not identical, to the SoC found in the Korean version of the Galaxy Note 4.
The Exynos 7 Octa will feature the familiar four Cortex-A57 cores for the heavy lifting tasks and four Cortex-A53 cores for improved energy efficiency. Accompany the latest ARMv8 CPU cores will be an ARM Mali-T760 GPU. It’s worth noting that Samsung didn’t make much of a fuss about its first Cortex-A57 and A53 powered SoC, the Exynos 5433. Therefore, the Exynos 7 appears to be a re-branding exercise in preparation for the wave of high-end ARMv8 processors heading our way next year.
The processor continues to make use of ARM’s big.LITTLE Heterogeneous Multi Processing (HMP) technology, which is used to scale loads across the most appropriate processor cores for a balance of energy efficiency and suitable performance. The Exynos 7 Octa range will be built on a 20nm manufacturing process.
Samsung hasn’t dished out details the range of clock speeds yet, but is boasting a 57 percent increase in CPU performance and a 74 percent increase in GPU performance compared with the previous Exynos generations. Before this gets your hopes up too much, the last Exynos 5 Octa chip listed officially on the Samsung website is the Exynos 5430, which was built from four Cortex-A15s, four Cortex-A7 cores and a Mali T628MP6 GPU. Still, that’s a nice performance gain compared with most of Samsung’s current-gen chips.
As far as features go, the chip supports 1440 x 2560 and 1600 x 2560 resolutions, as we’ve already seen from the Note 4. The SoC can also simultaneously record high definition video using the back and front-facing cameras and can output content to a 4K TV at a native resolution.
Next time we see an ARMv8 chip from Samsung it will likely be carrying the Exynos 7 Octa tag. We’ll have to wait and see if Samsung has applied some new clock speeds or tweaks when the first handset shows up, or if this is just a delayed launch and re-packaging of the 5433.
