The Exynos 5 Octa (5410) SoC by Samsung appeared first under the hood of the Samsung Galaxy S4 (GT-I9500 edition, not the Qualcomm Snapdragon-Version, the GT-I9505), and now an upgraded form of Samsung’s SoC regarded as the Exynos 5420 has been advertised by the known company.


Similiar to the older Samsung Exynos 5 Octa chip, the new Octa 5420 processor has eight cores, which are based upon ARM’s big.LITTLE design.

The big.LITTLE design architecture by ARM has four full-power ARM Cortex-A15 cores that are clocked at 1.8GHz as well as fourt Corext-A7 cores, clocked at 1.3GHz in order so save battery when the full power of the new Samsung Exynos 5 Octa 5420 is not needed because it is said that this big.LITTLE design of two different kinds of Cortex-cores offers more processing power and lower battery usage than only running the four A15 cores.

According to the information by Samsung, the new Exynos 5 Octa 5420 is an advanced revision of the now old Exynos 5 Octa processor, which works under the hood of the Samsung Galaxy S4 (GT-I9505) and it will boost the performance of the 3D graphic processing to double this 3D Graphic processing of the current Exynos 5 Octa SoC by Samsung (see below).

In addition, the new Samsung Exynos 5 Octa 5420 will be able to run complex and computationally intensive algorithms or operations on the GPU. It also has a complete support of OpenGL ES 3.0 and Full Profile Open CL 1.1..

According to Samsung, the new Exynos 5 Octa 5420 is about 20 percent faster in its CPU execution compared to the old Exynos 5 in the Galaxy S4 GT-I9505 of the manufacturer. Samsung new Soc additionally has double channel Lpddr3 at 933mhz for a super-wide memory bandwidth speed under its hood and will feature several new revisions of some features.

Of course, the new announcement about the new version of the Octa 5420 SoC is still pure marketing by Samsung. The new Samsung Exynos 5 Octa 5420 still has to prove these statements by the manufacture in upcoming reviews as well as in benchmarks compared with the old revision of this Samsung SoC.

As a sideline, the big differnce between the Exynos 5410 and 5420 is the Graphics Processing Unit (GPU). Samsung dropped the PowerVR Sgx544mp3 of the old Exynos 5 Octa-SoC and is using a Mali T628 Mp6 as Graphics Processing Unit (GPU) in the new Exynos 5 Octa 5420 and this step makes a lot of sense. The GPU processing of this Mali T628 Mp6 processing unit is a lot faster than is has been with the Sgx544mp3 from PowerVR.

Samsung Brings Enhanced Mobile Graphics Performance Capabilities to New Exynos 5 Octa Processor

SEOUL, South Korea–(BUSINESS WIRE)–Samsung Electronics Co., Ltd., a world leader in advanced semiconductor solutions, today introduced the latest addition to the Exynos product family with top level of graphic performance driven by a six-core ARM® Mali™-T628 GPU processor for the first time in the industry. With mobile use case scenarios becoming increasingly complex, Samsung’s newest eight-core ARM Cortex™-based application processor gives designers a powerful, energy efficient tool to build multifaceted user interface capabilities directly into the system architecture. Samsung will demonstrate the new Exynos 5 family at SIGGRAPH 2013 in the ARM booth, #357; Exhibit Hall C at the Anaheim Convention Center.

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 (2500×1600), 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.[/toggle]
