Well, Inorder to find out which chipset is better among the three chipsets, first of all we need to know how these chipsets are different from each other.
Now, let me explain them in detail
1.) Mediatek:
It is a chinese company. It uses more cores in it's processors(like octa core,hexa core,deca core).
Battery Life:
The mediatek chipsets are known to be more power draining and results in less battery life.Now they are optimizing their processors to be more power efficient but still lags behind their competetion in terms of battery life.
Performance:
Performance wise their processors are very good.Due the availability of extra cores,mediatek processors can handle intensive and heavy tasks and they are very good at multi-tasking.But we can see all this practically if we have sufficient Ram.Yes more cores demand more Ram to give best performance.
Heating Problem
Now coming to the heating problem. All the processors deliver heat while performing tasks. Mediatek processors deliver more heat(more cores=more heat) than the others.
Graphics:
Coming to graphics,Mediatek employs Mali graphics which is a third party graphics vendor(So graphics architectue is different from cpu and its performance may not match with cpu). It is really important to match the performances of cpu and gpu(graphics) so that the whole chipset performs efficiently and effectively.
2.)Snapdragon:
Snapdragon chipsets are manufactured by Qualcomm (American) company.
Snapdragon chipsets are not only just CPU's they incorporate other many processors in their chipsets.This is the main difference between Snapdragon and other chipsets.
Snapdragon chipsets are named as SoC's(System on chip) which means their chipsets(SoC's) have a CPU,GPU(Adreno Graphics),Image processor,Media processor,DSP(Digital Signal Processor),Cellular Modem unit,Wifi Modue,Radio Module,GPS Module,...etc. All these modules and Processors are inside of a snapdragon chip.Yes they incorporated all these things inside their chips.Hence their chips are costly.
Battery Life:
Snapdragon chipsets are best in terms of power efficiency compared to all other chipsets.
Performance:
Performance wise they perform really well. In multi-tasking,gaming,handling heavy and intensive tasks they are very good.
Heating Problem:
Snapdragon Processors generally deliver less heat compared to Mediatek and Intel Atom(Except the Snapdragon 810 Chipset-that faced many heating issues.)
Graphics:
Coming to graphics, they manufacture their own graphics called Adreno Graphics and incorporate into their chips. So here the performance of cpu and gpu are matched.
3.)Intel Atom:
Every one is familiar with Intel processors because they are dominant in the PC market. Intel Atom processors are the initiative taken by the company to enter into mobile segment.Intel processors are best in PC's but when it comes to mobile they have faced one problem...!
Battery Life:
Yes, the problem they faced is Battery life. Intel company has experience in manufactuting processors for PC's which consume power in watts(say 40 watts and above) but when it comes to mobile platform where the processors should run on power less than 5 watts, they had a problem in optimizing their processors to work on low power.
Don't worry that is all in the initial stage when they entered into mobile market. But recently in Q3 of 2015 they have announced their Mobile processors called core M-processors for mobile platform like tablets and smartphones. These processors are very power efficient and they consume power of 5 watts and below.But we may only see them in Smartphones or Tablets in 2016.
Performance:
Performance wise, i think i don't need to tell you how Intel Processors do. They are very good both at PC's and on Mobile.
Heating Problem:
Intel Atom Processors also deliver more heat when running heavy and CPU intensive tasks or while using for long duration.Let us see how their core M-Processors perform.
Graphics:
Intel, till now used third party graphic vendors like Power VGR and Mali graphics in their CPU's. Intel also have their own graphics called Intel Iris Graphics which they introduced in their 4th generation core i-series processors for PC's. I am not sure but i have read somewhere that core M-Processors have Intel Graphics built in. Let us see them in 2016.
After briefing all these things, Now tell me which chipset is better..?
My answer: Till now, Snapdragon is the clear winner here. I have practically used Smartphones which have all these three processors and telling you my answer.

op, thanks

bro yu sure yu research this tin well...i used one s4 that tym if e hot ehnnnn...i go press jean trouser nd getos go comot fian....instanta

Inconclusive without Exynos chipset.

OP you might have give some examples of devices that are using each chipset na

Op this ur list is Incomplete.. Where is KIRIN chipset from Huawei, even Exynos no dey ur list... Oya assignment, complete this ur list

YEA, I OWN A WIKO RAINBOW JAM IT RUNS ON SNAPDRAGON PROCESSORS. ITS SUPERB, FAST, LESS HEAT WHILE RUNNING HEAVY APPS like charging and browsing or charging and gaming The ba3life is wonderful, it has fast charge technology, even having a 2000mah capacity a full charge would last for an hour or less and would take up to 24hrs to drain up,that's if you're a heavy phone user

Ur post was superb n straight to the point . Snapdragon it is for me then

No need for long explanation.. Snapdragon , mediatek,Kirin,exynos,apple A-processor, NVIDIA tegra and Rockwell chips are all RISC(ARM based) processors. They are of low wattage,i.e. less power for task, and consume less power.hence the batteries last for longer time. While Intel and AMD are the CISC processors, also called 'X86' base processor. They are of high power and consumer more energy. Thus, battery last for a short time... This is why your iPhones and Android phones can never match the power of a computer.

A Pentium II powered device with low frequency is far more useful than snapdragon 820, which is 10x faster and more powerful than the Pentium processor.

Seun. Food is ready

The competition in the processor market is healthy. The Helio X10 was a competitive release from Mediatek, and the X20 is highly anticipated as the first decacore. Same with SD 820 and whatever that new Kirin is called. 950? Intel is coming up as well, but still have some way to go. Exynos isn't so widely in use from anything part from Samsung, but they sure are powerful.

I do not see how an android phone with 2,000mah battery can last 24 hrs with heavy usage. Haba... Shey the screen na 2 inch screen be the phone? Abi na monochrome phone.

Nice one

LOL.. ITS A 5.0 INCH SCREEN.. RUNS ON ANDROID 5.1

very informative...
am sure most people don't even know what's processors

Einsthawkton:


LOL.. ITS A 5.0 INCH SCREEN.. RUNS ON ANDROID 5.1

Then it is impossible for the battery to last 24hrs under heavy usage.

Einsthawkton:

And lasts for how long?

Xhaka:

And lasts for how long?

He claims it lasts 24 hrs with heavy usage

greenhulk:


He claims it lasts 24 hrs with heavy usage

Lmao!!!!
Even the likes of L5 and Gionee M3 don't last for 15hrs on heavy usage

Good

Xhaka:

u dey mind the guy. Phones with 5,000mah will struggle to last 18 hrs under heavy usage not to talk of a phone with 2,000mah

Xhaka:

And lasts for how long?

I had a full charge (trickle) in the morning.. See what I got left

If indeed ur phone has 2,000mah battery, and u still have 74% battery left by 5pm after charging in the morning, then u probably don't know what 'heavy usage' means. Trust me if i handle that phone the battery will be at 10% by 2pm.

Maybe you should check one out

You are right.

Einsthawkton:

I could tell you the same thing about a phone i just finish charging
A 2000mAh battery can't last for 24hrs on heavy usage
