Samsung Exynos 5 Octa CPU to have use of all 8 cores at one time starting in Q4
The setup allows big heavy duty tasks to run on the "big" A15 cores and small housekeeping chores can run on the "LITTLE" A7 cores without having to switch back and forth as currently required. Sammy's presser points out that being able to access all eight cores at once will improve 3D gaming, Augmented Reality, and advanced web browsing.
Samsung didn't say that we would see these chips in any current smartphone model, but it is a good bet that the Samsung Galaxy S5 will implement the silicon in at least some regions.

Samsung Electronics Co., Ltd., a world leader in advanced semiconductor solutions, today announced its Heterogeneous Multi-Processing (HMP) solution for the Exynos 5 Octa to fully maximize the benefits of the ARM® big.LITTLE™ technology. The HMP capability gives system-level designers the ability to develop solutions that deliver the right combination of high-performance and low-power to carry out tasks such as 3D gaming, complex augmented reality and advanced web browsing.
"It's usually assumed that the big CPU will do all the performance-critical work, however, power-efficient little cores can handle many significant workloads all on their own, so the workload is balanced within the system," said Taehoon Kim, vice president of System LSI marketing, Samsung Electronics. "big.LITTLE processing is designed to deliver the right combination of processors for a specific job. An eight-core processor with HMP is the truest form of the big.LITTLE technology with limitless benefits to the users of high-performance, low-power mobile products."
"ARM big.LITTLE multi-processing technology delivers the highest performance and efficiency across the widest range of workloads," said Noel Hurley, vice president, Strategy and Marketing, Processor Division, ARM. "We welcome Samsung's continued commitment to deploying the leading-edge technology on their latest chips featuring the ARM Cortex™-A series of processors, ARM Mali™ GPUs and ARM Artisan™ physical IP."
HMP is the most powerful use model for ARM big.LITTLE technology, as it enables the use of all physical cores at the same time. Software threads with high priority or high computational intensity can be allocated to the 'big' Cortex-A15 cores while threads with less priority or are less computationally intensive, can be performed by the 'LITTLE' Cortex-A7 cores, enabling a highly responsive, low-energy system to be built.
Software implementation is essential to maximizing the benefits of big.LITTLE technology. Multi-processing software controls the scheduling of threads of execution to the appropriate core. In earlier versions of the big.LITTLE software, the whole processor context is moved up to the 'big' core or down to the 'LITTLE' core based on the measured work load. In-depth study and analysis of diverse use case scenarios enable Samsung to achieve efficiency and high-performance, while managing power levels to deliver optimal user environments.
The HMP solution for Samsung's Exynos 5 Octa application processors will be available to customers in 4Q of 2013.

Imagine android on computers instead of windows,we would be running our computers with 50 cores+ cpu & 50+gb ram till date to remove lag & boost performance.More cores more & more innovation.Go android Go.

you have no idea how any of this works or what it means do you?
any x86 processor from the last 4 years still doesn't have to even think of worrying about falling behind ARM chips in performance, their priorities just haven't been comparable, until recently with intel's ATOM lineup, which DID suck back in 2007 but Is now improving out of sight.

RISC ≠ CISC
ARM ≠ x86/x86-64
x86 registers > ARM registers
x86 performance > ARM
As said above any x86/x86-64 processor from the last decade can easily outperform any ARM core to date. It has nothing to do with clock speeds or the number of cores on a die. Those are totally irrelevant as the x86 architecture is simply geared towards performance.

That going to be , one blazing hot phone lol,, not to mention what battery life , will look like

In theory, it should be more efficient and perform at cooler temperatures. Why? Well because there are more cores that are handling the processing of a task or application. You can think of a CPU as the neck to an hour glass with sand pouring through it. Obviously one CPU taking on a full load is going to perform very slowly and have to work very intensively in order to perform a range of tasks. Now imagine that you had 2, 4, or 8 cores (or if we are still using my example, necks to an hourglass) running those same processor intensive applications. The CPU will be able to more efficiently handle those tasks and it may not require as much power in order to do so. That is partially the reason why quad-core CPUs of today are more power efficient than the single or dual-core processors from a few years ago. Even if you built them using the same architecture, they will still be more power efficient than their single or dual-core counterparts.
Of course, this is all dependent on if they set up the processor the right way to handle tasks in this fashion. Obviously that was a problem Samsung had with it's first batch of Exynos processors which is why they are trying to improve it with this new technology.

+1 Nice points. Also, Exynos will be much better than MediaTek\\\'s Octa because hardly any app uses 4 cores these days let alone 8 thread setup. In this case what Exynos would do is it would turn on only 4 but powerful A15s instead of MediaTek\\\'s all 8-cores inferior A7s.
Not to mention unlike SD800 where all 4-cores are on at all times Exynos will be able to run only 1 or 2 cores if the task is less demanding which is something SD800 can\\\'t do.

This is what I hate about such articles. You provide incorrect information. The basic idea of SMP/GTS is *NOT* to make use of all 8 cores at same time. It's main idea is for scheduler to see all 8 cores. Any thread can run on any core. All cores might get used at same time, but very unlikely that they will be used for sustained period of time because of thermal constraints.

So the new Notes will not be using this tech then?
9. DukeX (Posts: 327; Member since: 28 Aug 2013)
So where are all the \"It cantz use all Zee caws at da Seem tiem\" bashers now?
12. Trex95 (Posts: 520; Member since: 03 Mar 2013)
So the S4 will turn to Ghost Rider phone or Johnny Storm phone Lol.
14. uchihakurtz (Posts: 171; Member since: 12 Nov 2012)
So we gonna see a possible lag-free TouchWiz in Q4?

Its not about how many cores you have
But how good are the cores .
Snapdragon over crapxynos any day .
Funny how two years ago people are saying the opposite
17. CX3NT3_713 (Posts: 1433; Member since: 18 Apr 2011)
Yea I noticed the same thing!!!! Now they all want it in thier phone
16. yowanvista (Posts: 275; Member since: 20 Sep 2011)
Any Exynos 5420 SoC (including that in the Note 3) can use any number of cores, it just depends on whether they implement GTS instead of IKS in the kernel. 5410 couldn\'t do that since it had a broken interconnect bus.

May be S5 would come up with this Octa CPU.
19. JMartin22 (Posts: 643; Member since: 30 Apr 2013)
They're still going to continue with the Exynos 5 series? They need to just leave that where it is and move forward with the Exynos 6 series. Cortex-A53 and 57 built upon ARM v8 instruction is the future. They'll be several times more powerful and energy efficient than A15 cores.
I hope this isn't what they're going to use for the early part of 2014.
21. yowanvista (Posts: 275; Member since: 20 Sep 2011)
Those are mainly Server-oriented Cortex cores which would provide zero benefit if implemented in a smartphone SoC. ARMv8 and it\'s 64-bit addressing mode is useless since you\'ll never need hundreds of Terabytes of RAM, furthermore Cortex-A15 can already address up to 1TB of RAM with LPAE. Moving up the Cortex line doesn\'t necessarily increase energy efficiency, more die shrinks are required to adapt those Cortex-A5x to embedded devices with a decent performance-energy balance. They are simply not meant to be used in smartphones.

you won't see Cortex-A53 and A57 until 2H/late 2014
24. proto (Posts: 44; Member since: 12 Sep 2012)
who need 8 cores? there is no need of them. Most apps using 2 cores...rarely 3 cores. Make better cores...not more.
For gaming you need better GPU not more cores on CPU.
I am happy, that qualcomm understands.
25. Bootutu (Posts: 162; Member since: 11 Jul 2013)
The present Note 3 supports HMP/GTS, why is this article refering to S5 next year?
27. power_x (Posts: 184; Member since: 28 Aug 2013)
But the problem is , most apps only uses 2 cores
But still a huge move by Samsung
28. nothingmuch (Posts: 131; Member since: 03 May 2013)
It dont matter none, its not gonna handle LTE anyways!
I think they need to work on the LTE factor before they go bragging on some extraordinary break through which dont pertain to hardly anybody.
I know im not the only one bummed about the note 3\'s ONLY variant in the US, i mean its still a beast but I want to to try out the new exynos too, its the only thing that really separates the big dogs and not just software differences from all devices with the same hardware!

New Samsung Exynos 5 Octa Can Now Fire-up All 8 Cores.. Nice!
