Samsung Teases With Image Of Exynos 5 Octa ChipsetBy cheatmaster 04:11 Thu, 15 Jul 2021 Comments
The Samsung Exynos 5 Octa chipset caused a lot of excitement and the SamsungExynos Twitter account is slowly fanning the flames with small teasing tidbits of info like this image of the chipset.
It’s a 3D render of the SoC rather than a photo of a production unit. In the same tweet, Samsung is talking up the energy efficiency of the chipset.

In case you missed it, the Exynos 5 Octa uses ARM’s big.LITTLE design. It has two groups of four processor cores – the gigantic group consists of four blazing quick Cortex-A15 CPUs, while the LITTLE group has four power-efficient Cortex-A7 cores. That’s eight-cores in total, hence Octa. Only one of the groups is active at a time, the other goes to sleep (similar to how NVIDIA's Tegra 3 chipset works, but with more low-power cores).
Samsung claims a 3.3x reduction in power usage thanks to the A7 cores, which are enough to handle menial tasks and are only 13% of the size of an A15 core, so they’re cheap. The overall performance is reportedly the same as an A15-only design. The switch between core groups happens in 30-50ms.
