Samsung might use custom cores in its next Exynos chipset: no Cortex-A72, welcome... "Mongoose"?

Samsung's latest chipset, the Exynos 7 Octa 7420 (powering the Galaxy S6 and the Galaxy S6 edge), is already shaping up to be a true powerhouse, but rumors about a new system-on-a-chip from South Korea are already circulating in the air. According to a new speculation, Samsung might not opt for Cortex-A72 cores, but develop a processor core on its own. At the moment, said custom core is codenamed "Mongoose" and will rely on the 14nm FinFET manufacturing process. It will employ the ARMv8 architecture, which paves the way for 64-bit functionality.

It's also said that the maximum clock speed of the core will be 2.3GHz, which is reportedly paving the way for impressive performance - according to a preliminary Geekbench 3 benchmark, the Mongoose accounted for a single-core score of 2,200, which is roughly 45% better than the single-core result of the Exynos 7420 (1,495 points). 

Still, we should once again mention that this is a rumor, so it's to be taken with a handful of salt, but given the fact that Samsung is taking its hardware game pretty seriously of late, we won't be surprised if it comes with a custom core for its next chipset. Who knows, the Galaxy Note 5 might end up being powered by a whole new SoC?

Fun fact: mongooses are among the natural enemies of the common krait (Bungarus caeruleus), a highly venomous snake. And which one of Samsung's rivals makes use of hardware with a similar naming? That's right, Qualcomm - the CPU units inside its Snapdragon 400/600/800-series chipsets are all called Krait.

lol.... 2,200 single-core performance while being an octacore CPU, meaning its core size is much smaller than Apple's dual-core cores? Impressive engineering feat if true. P.S. Author can't do math. It's around 47% stronger, not 33%.

Thank, AppleCultist, it's fixed now.

Check you should have listed to me when I mentioned this 12 hours back. Check my comment on this article.

Where does it state octacore?

That photo looks like Samsung's new 10nm finfet design.

still Apple with a dual-core A9 will be just as powerful as an octa-core Exynos LOL

No, it won't. With a dual-core, the A9's total performance will match last year's SnapDragon 801 performance. The A8 only has a 2,600 multicore score on GB for god's sake... There is nothing impressive about using two cores and then blowing up their sizes to get high single-core performance. This rumor, if true, is impressive, as 8 cores will limit the sizes of each core, yet the smaller cores each exceed the speed of Apple's large cores. Also, you forget that most of the A9's power will be thanks to Samsung's 14nm technology.

Yes but the OS would be as fast as other Android flagships. Good software+good specs=good phone. I can say the same for other flagships:D

There's not much more you can improve on in terms of UI speed. We're at or very close to the cap.

Thanks for correcting me bud but as far as I'm concerned, meshing the OS and its hardware in style is what makes a phone good. Most people in this website should know that.

Yes, and Apple definitely doesn't do that, especially with that kiddy-looking UI designed specifically for preteen girls.

Even on a Lumia 530 the OS is as fast as Android flagships , but it doesn't mean is as powerfull device..

Don't really get why people need to compare between Apple's and other SOC. Besides, there no holy grail apps that need a certain high performance SOC to run. Not like for the PCs there is Crysis. For years, the game has put many GPUs and CPUs to shame. Well, i do wish there is, a kill app/game that require super high end SOC.

Fate/stay night reference spotted!

Hope it was actually Fate/Zero reference since Stay Night was meh in all it's iterations.

Do you still think about this? Put A procesor to run a system like Chrome or even Android and we will see what then.

Apple A8 is almost 50% slower than Exynos 5433, lol.

It will be just as powerful as the Exynos 5420 from last year maximum (plus it uses the big.LITTLE technology which you don't seem to know much about)!

In single core, probably. But with MUCH larger cores. In multicore, not so much.

the snake shown in the pic is not a krait. it's a cobra.

IF those numbers are real it will be impressive. That woudl put that core in the line of the Cores for intel at least in Geekbench (EG: those are the numbers that Core M chips get). If on top of that there are 4 cores (I seriously doubt that) it would start being on the i5 range.

18. FluffyBled unregistered

I guess I'll wait for the next one then :o ... 2200 single core score is just immense! It even blows the 7420 out of the water!

There goes again! Whenever samsung gets the contract from apple for designing the chip. They then also implement on there chips too. Now it will be interesting to see that how much sammy can apply from apple and make already blistering fast exynos. But its also the Android has do a lot more to be as efficient and Ios

Oh, just stop with the excuse making and iRationalization. Samsung didn't copy anything from Apple core designs in the past. They just blew Apple away without copying anything now. Why would they start now?

27. FluffyBled unregistered

Apple is all iFans can think about ... don't bother replying their comments! They just have to bring this excuse in every article about Samsung!

Im an Apple fan but not a propagandist. Basically, those have been fed with the poison Apple. (Used Apple for humor. Dont think of me as a hypocrite)

first of all not a Apple fan though i have Iphone 6 plus and ipad mini 2, and second thing is that Samy does copy the apple chip chip design and they can do it because they have all the blueprints when they develop a chip for apple. And this is a good thing not a bad thing as modfying already superb Exynos with new Tech.

As a mod of the linked "Tieba" source, I'm very surpised about there are people who actually take speculation from that poster with any weight..
