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.

Samsung's new Exynos 5 Octa (product code : Exynos 5420), based on ARM Mali™-T628 MP6 cores, boosts 3D graphic processing capabilities that are over two times greater than the Exynos 5 Octa predecessor. The newest member of the Exynos family is able to perform General-Purpose computing on Graphics Processing Units (GPGPU) accelerating complex and computationally intensive algorithms or operations, traditionally processed by the CPU. This product also supports OpenGL® ES 3.0 and Full Profile Open CL 1.1, which enables the horsepower needed in multi-layer rendering of high-end, complex gaming scenarios, post-processing and sharing of photos and video, as well as general high-function multi-tasking operations.
"ARM welcomes the latest addition to the successful Exynos Octa 5 series, which uses ARM's Mali GPU solution to dramatically improve graphics performance," said Pete Hutton, executive vice president & general manager, Media Processing Division, ARM. "ARM big.LITTLE™ and ARM Artisan® Physical IP technologies continue to be at the heart of the Octa series and now complement the new functionality brought by ARM GPU Compute. This combination enables unprecedented capabilities in areas such as facial detection and gesture control, and brings desktop-quality editing of images and video to mobile devices."
"Demand for richer graphic experiences is growing rapidly nowadays," said Taehoon Kim, vice president of System LSI marketing, Samsung Electronics. "In order to meet that demand from both OEMs and end users, we developed this processor which enables superb graphical performance without compromising power consumption."
The newest Exynos processor is powered by four ARM Cortex®-A15™ processors at 1.8GHz with four additional Cortex-A7™ cores at 1.3 GHz in a big.LITTLE processing implementation. This improves the CPU processing capability by 20 percent over the predecessor by optimizing the power-saving design.
In addition, the multiple image compression (MIC) IP block inside this System-on-Chip successfully lowers the total system power when bringing pictures or multimedia from memory to display panel. This feature results in maximizing the usage hours of mobile devices with a high-resolution display such as WQXGA (2500x1600), in particular when browsing the web or doing multimedia application requiring the frequent screen refresh.
The new Exynos 5 Octa processor also features a memory bandwidth of 14.9 gigabytes per second paired with a dual-channel LPDDR3 at 933MHz, enabling an industry-leading fast data processing and support for full HD Wifi display. This new processor also incorporates a variety of full HD 60 frames per second video hardware codec engines for 1080p video recording and playback.
The new family of Exynos 5 Octa is currently sampling to customers and is scheduled for mass-production in August.
