Exynos OctaIt should come as no surprise that next year's chips will be better than this years. Moore's Law and common sense tell us that product specification will continue to rise, even if we no longer need them to be more powerful. The CPU in your smartphone is no different.

Samsung has unveiled the new Exynos 5 Octa 5420, which has a six-core ARM Mali-T628 GPU and runs a big.LITTLE implementation with four ARM Cortex-A15 cores at 1.8 GHz, and four Cortex-A7 cores at 1.3GHz . Samsung says this new chip will boost 3D graphic processing performance to double that of the current Exynos 5 Octa, be able to run complex and computationally intensive algorithms or operations on the GPU, and fully support OpenGL ES 3.0 and Full Profile Open CL 1.1. These are the types of advancements that mean more than extra cores and more Gigahertz, and will open new opportunities for vendors who use the chips in mobile devices and laptops. 

The new Exynos is currently being shopped around to OEMs and vendors, and we should expect to see the chip go into full production in August. The full press release follows the jump.

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 (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.

Samsung's new Exynos 5 Octa 5420 brings double the GPU power of the current silicon


None of those specs are going to matter if Samsung continues to optimize their software to have built in lag and delay. Their Touchwiz software has built in slowdown.

While not as horrible as a lot of people put... Yes, Touchwiz, is showing its age

You don't get it, Samsung is doing its customers a favour! By building in lag and slowdown they keep your complexion free from the face-melting speeds their hardware really should be achieving! XP

Not that it is a perfect phone, but you must not own one. The only lag is from not having some stupid transition from screen to screen. Turning the transition speeds up and the "lag" goes away.



This is so true! I use the Galaxy S3 and touchwiz on my phone is surprisingly very fast and smooth! My brother has the GS4 and his phone has very noticeable lag and delay. Either way I'll wait to get a phone with the Snapdragon 800 chip

if your concern is raw CPU compute then the wait will be worth it. But if it is graphics, or memory subsystem —these are things that will be improving beyond the snapdragon 800 with the new chipset.

the gpu should come in at roughly 25fps in GFXBench 2.7 (T-rex): it would be faster than anything ARM or iOS related by a wide margin. The ram is up from 800Mhz to 933Mhz.

now .. will they actually use the chip in a new S4 or Note III? I'm not sure. It won't be in production until August, making it very late for this year, and far too early for next year (in fact, still 28nm which completely outdates it for next year).

Its the same on the S4. The problem is that it's also much slower than not only aosp but also but also the HTC One and Optimus G Pro. Samsung has intentionally slowed down their software.

I don't get why so many people complain about Touchwiz. Am I the only one who is happy with it? It is odd that I find d Touchwiz very useful and add features to otherwise dull Android 4.1 OS.

Posted using Samsung GS III

I'm totally excited by these new chips - intel's haswell - I just can't wait to see where mobile computing is headed. This is really fantastic.

Double the GPU power is marketing speak. How does it compare with the competition?

"The new Exynos is currently being shopped around to OEMs and vendors"

Are there OEMs other than Samsung using Exynos? I thought Samsung was its number 1 customer.

I could see the next Nexus 10 be made by Samsung and include this chip. That'd be an interesting buy.

Exotic.. Yes.
For Me?.. No.
I personally would rather have the simplicity and raw 2.2 - 2.3 Ghz Power of the Snapdragon 800.. with the die at .28nm, the 2nd big batch of those chips released late 2013 early 2014 will be overclocking monsters.. 2.6 - 2.8 should easily be within reach.. I can't wait to play with the 800 in my next cellular device.

Look, I need a no BS assessment. I have the G3 but was thinking of getting the G4 for my aunt and sprint is having a buy one get one. Ill use their upgrade, not mine. Hook her up and get a new model for myself to boot. I don't pretend to know all the techno jargon. Should I just wait for the note 3 or G5? To a layman like myself, these new chips sound crazy! Remember, though a true fan of this site, and all things tech, I am not half knowledgeable as I wish to be. If you dare, explain it to me as if I were a 10 year old. To those that respond, I truly appriciate and trust your input. Thanks friends!

I greet this news with a resounding MEH

I got fooled into buying the S4 I9500 Exynos Octa model...and it's something I bitterly regret as the battery life is markedly inferior to the Snapdragon 600 version. Sure, it benchmarks higher, but for actual USE of the phone the Snapdragon 600 lasts far longer and has a much more vibrant modding community.

Vapid and foolish fanboys who are easily impressed by artificial benchmarks can cling to this one, I am definitely going with the S800 route for the Galaxy Note III when it comes out.

I wouldn't take an Exynos device even Samsung gave it to me. Not interested in closed source of whatever Samsung wants to call it.

This means nothing if it still operates under cluster migration. (all 4 small cores or all 4 large cores)

Best and funniest post I've read in a long time. Let me add to it. Does anyone know how the exynos CM 10 stable builds are coming along?
