Samsung Uleashes Exynos 7 Octa ARM Cortex-A57 And Cortex-A53-Based 20nm Powerhouse Mobile Chip

It's been a busy week in mobile. To recap, Google added a couple of Nexus devices to its lineup courtesy of Motorola and HTC, there's a new version of Android (Lollipop), and Apple rolled out new iPad tablets. Given how hectic it's been, one can forgive Samsung for quietly updating its processor page with its new Exynos 7 Octa.

Believed to be the same SoC found in the Galaxy Note 4, the Exynos 7 Octa rocks four ARM-based Cortex-A57 and four Cortex-A53 cores, which combine for a 57 percent boost in CPU performance compared to the previous generation Exynos 5 Octa.

Like before, Samsung's chip utilizes ARM's big.LITTLE Heterogeneous Multi Processing (HMP) to dump loads on the appropriate set of cores. For heavy lifting duties, the Cortex-A57 cores kick into high gear, while the Cortex-A53 cores handle less demanding loads, like background tasks. Unlike earlier versions of big.LITTLE, HMP enables all cores to fire up at the same time. This allows devices built around the Exynos 7 to be able to handle high-end tasks while balancing battery life.

The chip is built on a 20nm manufacturing process and includes an upgraded ARM Mali T-760 GPU that offers users a 74 percent jump in graphics performance. It's also infused with various side technologies, such as mobile image compression (MIC), an advanced multimedia format codec (MFC), support for WQHD and WQXGA displays, and a built-in dual Image Signal Processor (ISP) with support for 16MP 30fps (rear) and 5MP 30fps (front) simultaneous video recording
