I don't think there are apps that will benefit from deca-core SoCs right now. Apart from the attendant high power draw which has been pointed out, it will just be used for pointless marketing.

MATURELION:
well to be honest with you number of cores sometimes matter even in mobile devices, it's just like labour division, say if 8 people are pulling water out of a well no matter how small they are if they got enough speed they'll do a perfect job in performance than when 2 persons are doing the same job even at greater speed, and when it comes to mobile it all boils down to architecture of the processor... so yeah it won't be overkill having 10 cores cos las las peformance demand on mobile devices is going up rather this recent years

seunfly:


I understand ur logic, if those core is not too far apart in terms of performance but in a situation where the core is extreemly less powerful, i will prefer a more powerful core that will get the job done in matter of nano seconds comapre to the weak cores that will get the job done in milisecound.

They say heads are better than one, but it is not always true.

The processor or SoC (System on a chip) of a Smartphone can be thought of as the brain of that smartphone.

This processor contains several things. The most important of which are CPUs.

A CPU or Central Processing Unit is responsible for carrying out the tasks and managing the functions of your Smartphone computer.

Your Processor in your Smartphone may contain several CPUs.

Each of this CPUs inside the SoC are referred to as a CORE.

If a processor has:

1 CPU, it's called a Single Core processor

2 CPUs, it's called a Dual Core processor

4 CPUs, it's called a Quad Core processor

6 CPUs, it's called a Hexa Core processor

8 CPUs, it's called a Octa Core processor

10 CPUs, it's called a Deca Core processor


Types of CPUs for Smartphones (Android)

The main company that designs CPUs for all androids is called ARM.

They then sell their design to SoC retailers/manufacturers who then use the design by ARM to build their own Unique CPU.

There are two types of CPUs widely in use in the market now to build SoCs. They are:

1. The ARM cortex A50 series which are used for only light tasks such as making calls, scrolling through FB, WhatsApp chatting, reading an eBook etc.
The A50 series consists of A53, A55 and A57

The exception here is the A57 core which is a powerful core used for heavy tasks. It is the predecessor of the A70 Series. (thank you @Naijasensei)


2. The ARM cortex A70 series which are used for heavy tasks like HD gaming, Video calls, Screen casting etc.
The A70 series consists of A72, A73, A75, A76, A77

A77 is the best currently in the market.

A few questions people may want to ask...

1. Do more Cores equal a better performance?
Well yes and no.

Yes because more CPU helps share the load of processing data and outputs the results faster making apps feel smoother and run faster.

No. Because sometimes more CPU cores isn't necessarily the answer. A Quad core A76/A55 CPU set will outperform an Octa core A57 set by far.

Then there's also optimization. This is when apps and tasks are tailor made to run smoothly on CPUs. This is why a Quad core iPhone may completely destroy an Octa-core midrange android device.

This answer to this question relies on you the individual looking at the CPU spec sheet as well as clock speed.

2. If two CPU cores are compared, is the one with the faster clock speed the best?

Well yes and no again.

Yes, if the two CPUs are of the same architecture e.g A72 Vs A72. They are both equal in every way so the only way to set them apart is the clock speed.

No. If the two CPUs are of different architectures e.g A73 Vs A76. If you like, dash the A73 a clock speed of 2.5GHz, an A76 of 2.0GHz will stroll pass it on a speedtest like Usain Bolt.

For any other question, please comment and I'll answer to the best of my knowledge.

Cheers.

MATURELION:
you're right, it's just like intels i5 8500u (using it as an example) the only thing keeping that processor relevant in the i5 series is turbo boost technology (where the speeds bump up with more load applied for a certain amount of time before bottlenecking), but suppose they don't lower the speed? Or would that be unrealistic for mobile devices?

Donvic4u:
Someone pls list snapdragon chips according to the their power

ZesusHVWritter:

On the contrary, 10 core is better.
Instead of have big-little core configuration of 2 powerful core, 2 less powerful core and 4 average performing core.

For 10 cores it becomes this.
3 powerful cores.
3 less powerful cores.
4 average performing cores.

And there is no power consumption problem, instead, its more power efficient. When the more power intense cores are not needed, they are completely dormant.
But when they are needed, the 3cores will complete tasks 20% faster against the performance of the 2 cores.
This actually brings better performance and more efficient use of the battery life and less heating.

The only shortcoming when the 10core architecture is considered, its developing a cpu smart enough to properly distribute the workload appropriately.

I am confident that issue won't be a problem for long, if it can be done for Octacore, decacore isn't far behind.

Some unverified information/speculation are claiming Mediatek is working on a twelve core chipset with ARM.

Please remember where you heard it first. From me :}

naijasensei:


As you pointed out earlier, desktop and laptop CPUs are a completely different kettle of fish. The core-i U series CPUs are for low power usage scenarios, for example ultrabooks and 2-in-1 convertible laptops (The U stands for Ulira Low Voltage), because they have a TDP of 15W compared to the typical >=45W TDP of other CPUs. The boost mode (burst mode) is not for sustained workloads, just like the highest speed setting on a blender, or the red line a car's speedometer. The U series CPUs are not designed for that type of usage.

naijasensei:


Even if the speculation is true, I am sure they won't first come to smartphones.

I totally understand what you're trying to point out, but suppose it's the same idea they're trying to bring to deca cores? Cos power consumption in mobile devices is 2 ways, up the battery capacity or lower the power draw

Ifycharlie2:


Bro no doubt to what u re saying but let me correct some errors...when u talk about architectural designs of SOC(system on chip). The Arm cortex is one of a feature of a chip..

Wen chosen a smartphone to buy we have different chipsets..these chipsets houses the processor speed,and all other Arithmetic performances to improve the functionality and durability of your device

In the phone market brands like iPhone,Samsung, Huawei and others have specifically designed there own chipsets in other to increase there market value

Samsung was using the snapdragon chipsets but has a low Arm cortex feature..before the company designed there own chipsets Called EXYNOS. This EXYNOS has a good clockspeed and has a good memory fetch cycle. Though EXYNOS comes in series the higher the series the better the performance.it also comes with an double octer-core processors (8-cores) and with a good Arm cortex. First chipsets with a 1TB and 16GB ram

Then the almighty Huawei came with a HILLSONIC KIRIN..these is one of the best chipsets with a good processing units first chipsets to get the 5G feature..with a low power consumption and 3.5 Hz clockspeed

Tecno and infinix uses MEDIATEK
THE midiatek chipsets uses Ai camera..good cores ..higher battery efficiency..etc

Note: when buying a smart phone
1: check the battery capacity
2: the ram(we have double data ram and single data ram.
3: check the chipsets and it's series(the higher the series the higher the efficiency)
4:check processors and there refreshing rates(we have octacore(8-cores),(dualcore 4-cores),(hexacore 7-cores). Also some phones with hexacore like the iPhone can do more better performance than a tecno phone with 8- cores, becuz of the Arm coretx series and the frequency Hertz of the device.

5: check the GPU( Graphics processing uints)
6: check the resolution. The higher the pixel the brighter and quality it gives u.
7: check the 4G bands..(most people who uses phone that didn't supports Glo 4G bands may not experience the super speed of 4G)

it has already been employed in core i9 cpus 10th gen, but since smartphones run on completely different architectures (RISC) all we can do is fold our hands and wait, to be honest these are the kind of things I wish I could explore here in the shit hole county, knowledge is just wasting

naijasensei:


In smartphones, increasing battery capacity is a luxury many manufacturers can't afford, hence the more realistic approach of reducing power consumption.

The Redmi Note 9S (or Pro) with the SD720G will slightly outperform the Mi 9T (or Redmi K20) with the SD730.

Both the 730 and the 720G come with A76 CPUs for their heavy lifting but the 730 is clocked at 2.2GHz while the 720G is clocked at 2.3GHz. This alone gives it a slight nudge ahead.

This will reflect in GeekBench and Antutu benchmarks when the 720G holds a slight lead over the 730. This is in terms of CPU performance alone.

As we be Africans, na numbers dey move us. I once tried to show someone that SD675 was far superior to SD665. He almost took my head off. He refused to agree that SD675 had a better performance. In truth SD675 performed as well as, if not even better than the SD710 and 712.

All those numbers are for marketing. The new SD690 5G will destroy SD710 and 712 too yet if you look at the names, you'll think otherwise.

Let the architecture and the bench marks show you the way Baba.

The Mi Note 10 cameras na die oh

Osasnidas:



So oga athiestandproud, quick question

So i did a google search about the unisoc sc9863a an Octacore cpu of 1.6ghz/1.2ghz clock speed with cortex A55 and 28nm High performance chip

And compared to helio p22 of Octa core of 2.0ghz cortex A53 and 12nm finfet

Cortex A55 is the successor of A53 from what i discovered
Putting the fabrication aside and judging by your post

Will the unisoc chipset outperform the helio p22 even with lesser clock speed and a better cortex ?

atheistandproud:


When discussing processor's sha. Unisoc is the black sheep of the family.

Unisoc may have the more advanced cores on paper but their manufacturing process is backward. Those A55s will encounter a bottle neck (like water trapped in a bottle, the CPU has the power to deliver in large quantities but will only release it in small amounts) in processing because a lot of that power will be lost as heat, then also that die size is too big to be effectively efficient and fast in moving data around the integrated circuit.

The P22 is better despite having the weaker CPUs on paper because it's is smaller, more advanced with a proper arrangements of the cores in the circuit to take advantage of efficient data processing and caching. It also loses less power as heat. And finally, it's faster.

Unlike the 70 series, there's not that huge of a difference between the 53 and 55.

I hope I tried.

In conclusion: putting the fabrication and everything else aside, the unisoc sc9863a should be a bit powerful than the Helio P22.

I guess this was your question

ZesusHVWritter:

Hopefully that won't be the case. On the other front, there over a 100 app that have gotten more demanding after few updates, of my head I can tell you Facebook and Instagram.

A smartphone like someone said "is the companion you are closest to these days."
Smartphones are getting smarter and hungrier now, instead of increasing spead of cpus and gpus. More cores will bring a less burning solution. You can have 3 cores performing at 2.5GHZ making a total of 7.5GHZ on chip speed.
But it will be crazy to have 2 cores running at 3.7GHZ each and not expect the device to become a frying pan.

naijasensei:


Spreading processing load among more cores would be good, because cores running at lower frequencies will be less likely to overheat. But, as for those two naughty apps you mentioned, they are in serious need of better optimization.

ZesusHVWritter:

Zurkerberg isn't interested, because letting these apps run wild also allow data leak that won't be traced back to them.
