Exynos 5420 Octa shown utilizing all of its eight cores simultaneously

Samsung's in-house foray into thesemiconductor's industry in the form of its Exynos SoCs has, undeniably, managed to etch a spot for itself. But though we see it in somehigh end, modern devices, there are those of us who have beenpondering whether Samsung's sheer size has played an integral role inits continued survival, more so than its own merits. And while thosesure are abundant, an overarching concern has been on the agenda forthe past year as far as the last two models of the SoC are concerned.Namely, while ARM's big.LITTLE platform sounds great on paper, theExynos 5410 and 5420 have been unable to take advantage of all eightCortex cores simultaneously.



Untilthe other day, when Samsung announced that the Exynos 5420 Octawill finally support Heterogeneous Multi-Processing (HMP), or saidotherwise – it will finally allow the chipset to take advantage ofall eight cores' computing muscle at the same time.



Deciding to visually showcase whatHMP means, ARM, on whose platform the Exynos is based, has released atrio of short clips exemplifying the behavior of the chipset underseveral real world scenarios, and has also demoed the usefulness ofGPUCompute. As you're about to witness for yourself, the four smaller, Cortex-A7 cores are capable enough to handle most of the typical tasks a user goes through on his smartphone, but they will be now backed by the other four, more powerful Cortex-A15 cores whenever 'typical' just doesn't cut it.

Great. HPM is the most eficient and powerful implementation of big.LITTE. Hope to see how it is vs s800

Like in all previous benchmark tests... When Exynos vs Snapdragon met head to head... My only b!tch of the article is "WHY" didn't MediaTek get mentioned by the writer Chris P..!. It's normal for Samsung to copy and not give credit where credits due... But, PA and it's knowledgeable writers should know better. Congratulation once again "MediaTek", for opening the door for Octa Core.

I believe the HMP processing for BIG.little was designed by ARM. It is a software "tweak" to their BIG.little architecture, and should be supported on all BIG.little systems fitting ARM specs. MediaTek just announced that they will support a product with it first. http://www.arm.com/files/downloads/Software_Techniques_for_ARM_big.LITTLE_Systems.pdf

Oh, the first time I can see the word "foolish" or "stupid" are not enough for describe you. Knowledge? You know nothing.

Dude, you are full of $hit.. mediatek has nothing to do with GTS implementation of Octacore. It was done by Linaro. Check the members of Linaro:http://www.linaro.org/members

Dude, do yourself a favour, make some research before you post stupid comments on here.

Better than 64bit- architecture

64 bit is useless, but not ARMv8 ISA

Until phones are using 4GB of ram it is useless and a 100% marketing gimmick.

8 cores>>still lags LMAO!!!!

Isn't it the bloatware and skin over the UI (touch wiz) that makes it lag? ._.

21. hung2900

S4 lags due to the stupid broken CCI-400 coherent of 5410 SoC. 5420 is simply different

26. red_fox unregistered

Touch Wiz or other OEM skined UI? yeah sure maybe, but my vanilla android nexus 4 sure flies, no hiccups at all.

Finally it took them 3 years for OEMS to realise that Android no longer lags if only this A15s were used on 2010 devices! Android a full OS needs raw pure CPU power to push it's OS! A9, A8 Cortex were all a failure! Flash was heavy and needed lots of RAM and CPU power. S800 Snapdragon is an over clocked S600 which is clocked at 2.3Ghz. So Snapdragon does not even have a true A15 Socs yet! Samsung already has 8 months ago! ™

I own the nexus 10 Samsung Exynos 5250, 1.7 GHz dual-core Cortex-A15, Mali T604 GPU and still lag randomly.

On IPhone 5s it's not useless cause all Mac bro, IMac already 64 bit and this an Apple IOSX not Android OS and Samsung phones.

Useless until android implements I guess.

Virtually useless until a phone sports 4gb of ram or more, regardless of platform.

34. scumbledEGG unregistered

64bit after math is the true octacore, so biglittle octacore was just a gimmick??? staying with ios than octa/customizable bloatwares of android...

This is why people need to curb the "My phone is faster than yours" bragging rights. Apple continues to push how much faster their phones are every launch, yet forget that society is already groomed to know that the next iteration will be faster. The leapfrogging of technology should quell the need to brag how newer phones are faster. Tomorrow, something else will trump the previous. I have continually hammered the rule of thumb: If you need to upgrade, purchase on the premise of the most features and functions you possibly can to grow with the lastest offerings. If at time of upgrade, Apple meets this goal; go for it. But, if you can wait, the next manufacturer of your choice should be the purchase made. In electronics, one can only brag on owning the newest for a very short time. Then it becomes someone else's brag. John B.

I'm genuinely sick of this "My phone is faster". Several Android manufacters and Apple have showed you don't need a huge number of cores or ghz or RAM to have a smooth exprience. I don't have the possibility to buy a smartphone, I have a old one for three years now, but if I were to buy one I would buy the iPhone. I don't care about the specs if the performance and battery life is the same as the SGS4 for example. I want a good and smooth experience and th ecosystem is too good to leave now that I have a Macbook and iPad. I know that Android is better in some things and has better specs but it always goes down to experience. I would still only upgrade to another smartphone every two years, I like the iPhone upgrades but not enough to get one every year and yet the old ones are still supported to the latest OS.

Most people can't upgrade until the two years is up. This is common society. Many tech geeks and employees of carriers, often brag about the newest technology but forget that the rest of us don't have the luxury of getting new devices dirt cheap(or free), every 8 months to a year. I endorse your position.Once in the Apple ecosystem, it is very tough to leave. John B.

Based on your theory, Apple will never get a passing mention and yet there a lot of people that are willing to pay US$900 for a 4" phone because its the latest iPhone. People are bias and buy what they think its the best, What i would hope for is people will be gracious enough to accept this fact and move on rather than spent a large portion of their life justify to stranger that wouldn't agree or care about their life choices. Spent the other half of their life trash talking on Android posting and vice via.

This is not theory Joey. In the days of PCs, It was always common nature to purchase the most you could afford in order to save annoyance of outgrowing the computer too quickly.Things haven't changed except the fact we are more mobile than years ago. The Apple vs all others hasn't changed either. It will always be Roe Vs Wade. I owned Apple products for a little over 10 years during the PC years. Great product with many benefits. However, switching to windows didn't change my lifestyle or goals and neither has Android. Android today, has proven to be a very stable ecosystem with regular updates that can seemingly adapt to previous versions rather nicely. I don't care what other people own. I do, however, feel that most people bragging of their products, live unrealistically through hyperbole and mass marketing to the point that it clouds factual content. That is the whole point of my post. I've been around tech most of my 52 years. I have a passion for it and my current job allows me to enjoy upcoming technology. I value being able to enjoy the latest technology in the wireless industry as well. For this I have chosen to embrace Android. I'm not biased towards Android.I chose it for how I like my technology. Just as Apple customers prefer theirs. However, on more and more occassions, I have heard complaints from some of my friends that own Apple products, that they are getting tired of waiting to get what everyone else has already. My thoughts on this is, that they are not true Apple fans. They followed a certain path based on popularity and have expressed descention. Those that love Apple without complaints,are accepting of waiting a bit until it is offered on their devices. But to brag that they have an iphone because it does this or does that, only incubates needless arrogance that then fosters misaligned reality. John B.

I use to have Samsung galaxy s2, I wonder what difference iPhone 5s have from it.. Specs. Wise

The s2 on gingerbread is still the smoothest android experience I have had. That was such a great phone.

It got updated to Jellybean. I'm not sure if it's getting the 4.2.2 or 4.3 update, but then again XDA will take care of that.

As soon as I got ICS on my SGSII, I never got over 4 hours battery. Reset the phone -- no difference. I was really happy until the update. That's when I went to Sprint and grabbed the NoteII.

@ bucky. you are right. when I play FIFA 12 on my quad jellybean phone it take a liitle while to load though no lag after load and graphic is great but it load much faster on s2 but graphic rendering not too great
