Qualcomm vs Mediatek : Which Smartphone Processor Should You Choose?

Why should you prefer Qualcomm over MediaTek while choosing a smartphone processor? How is Qualcomm different from MediaTek? Read through to find out...
Mediatek vs Qualcomm

This is the era of smartphones and smart devices. Day-by-day smartphones are getting well equipped with new and more advanced technologies. There was a day when smartphones featured only few MB's of RAM and processors with very less clock-speed. But today the scene has changed and is changing very rapidly.

The smartphones of today are much powerful with high-speed multi-core processors and large LPDDR3/ LPDDR4 RAMs. Their performance and features and now comparable to laptops and sometimes they even surpass them.

But, this rapid advancement in technology has provoked people to upgrade their smartphones. Today, smartphones have become cheaper, even people with a tight budget can get better smartphones at a reasonable price. Again for this to happen people must have some basic technical knowledge about the smartphone hardware. Because there are many OEMs which are selling smartphones with cheap hardware at high prices to earn maximum profit. One of the most important hardware of a smartphone is its processor and chipset, collectively known as SoC (system on chip). This is basically the heart of a smartphone as it affects the smartphone in every aspect, from performance to battery backup, from graphics to camera capabilities.

The processor of a smartphone is responsible for its processing speed, multitasking capacity, smooth performance, battery backup and efficiency in handling heavy tasks without much heating. And smartphone chipset, which is also supplied by the processor manufacturer, contains other important hardware capabilities like network connectivity, Wi-Fi, Bluetooth, audio processing, video processing, RAM capacity, camera capacity (x Mega Pixels), display capability (HD, FHD, QHD, 4K) etc. Even the GPU (Graphics Processing Unit), which is responsible for graphics performance and detail, is also supplied by the processor manufacturer. Basically, both the chipset and the GPU come integrated with the processor and not supplied separately. So, the quality of GPU and chipset depends on what processor you choose.


MediaTek vs Qualcomm

Qualcomm - Mediatek

There was a time a few years back when MediaTek processors were popular among budget and mid-range phones. There were no good Qualcomm processors which could provide value for money as compared to their MediaTek counterparts. As MediaTek processors were cheaper and were capable of giving satisfactory performance, they were widely used by manufacturers in the budget and mid-range smartphones.

But, today the scenario is different. Now we have good Qualcomm Snapdragon processors (SoC's) in budget and mid-range as well. And they are giving a good competition to MediaTek not only in price but also in providing overall end-user experience. So let's see how Qualcomm performs as compared to MediaTek. Is it better?



Origin: Old vs New

Qualcomm Company

Qualcomm is an American company which started in 1985. Its first products included OmniTRACS, a satellite locating and messaging service, and also various specialized IC's (Integrated Circuits) for digital radio communication. It launched its first Snapdragon processor in 2005 when no one knew how smartphone market will overtake feature phones and other electronics in the coming decade.

Mediatek Company

On the other hand, MediaTek is a Taiwanese company started in 1997. It was previously a unit of United Microelectronics Corporation. MediaTek started with manufacturing chipsets for optical drives and subsequently expanded to chip solutions for DVD players, digital TV's, mobile phones, smartphones and tablets. First MediaTek processor was used in a smartphone in 2009.

However, Qualcomm and MediaTek started testing smartphone processors almost in the same period, but Qualcomm quickly gained a larger share in the smartphone market. Qualcomm was already a big IC manufacturer, which also became a leading smartphone SoC manufacturer. So why had Qualcomm a larger share? How Qualcomm was different?


Technology and Architectural Design

Snapdragon Chip


Both Qualcomm and MediaTek use ARM architecture to manufacture their processors. There is no harm in that. But while MediaTek directly implements ARM's architectural design without much research and improvements in manufacturing its processors, Qualcomm, on the other hand, spends a lot of money in research and development in tweaking its processors for best user experience. It does not directly use the ARM's instruction set to manufacture its processors. It works to improve the design and tries to remove some flaws if any. And this is where Qualcomm stands ahead of MediaTek.

Qualcomm Technology Evolution

Also, Qualcomm tries to use better manufacturing technologies like 14nm (lower is better) and sometimes even 10 nm for better efficiency. But MediaTek has been using technologies of 28nm, 20nm in its processors, which is not that good. If we compare two popular processors from both the brands, Qualcomm Snapdragon 625 comes with a 14nm technology and MediaTek Helio P25 packs a 16nm technology.

However, the recent MediaTek Helio processors seem to perform far better than its predecessors, especially the Helio X30 which comes with the 10nm technology. Although MediaTek is releasing newer processors, it still lags behind Snapdragon SoC in many aspects.


Number Game : More Cores vs Better Efficiency

Mediatek Helio X20 Specs

If you see the specs of MediaTek processors, you may find them pretty impressive at least on paper. MediaTek gives more focus on power and performance. Like showing off deca-core processors, 2.x GHz clock speed etc. What MediaTek does is basically a tricky number game to attract buyers by showing high benchmark scores. It only exaggerates the specs, for example even if you have a deca-core processor with 2.6 GHz clock speed, but a 20nm technology (e.g. MediaTek Helio x27) won't give you better efficiency. On the other hand, it will result in overheating and huge battery drain. This is what happens in MediaTek. As I have said, MediaTek doesn't work much in tweaking processors and doesn't care much about the end-user experience.

But, Qualcomm puts a lot of effort in tweaking its processors for better efficiency. Qualcomm's R&D works hard to modify the design for a balanced performance. Yes, Qualcomm processors don't have deca-core and higher clock speed in similar price brackets like that of MediaTek. But they provide a better battery backup, less heating and smoother performance. All in all, they give a better user experience. And obviously, due to this Qualcomm Snapdragon processors are more durable than MediaTek's.


GPU (Graphics Processing Unit)

How is MediaTek in graphics performance? Is it better than Qualcomm?

MediaTek uses Mali GPU for most of its processors, which is provided by ARM itself. The performance of Mali GPU in MediaTek processors is not promising and not at all comparable to that of Qualcomm's GPU. Well, the problem is not in Mali GPU. It's good, even Samsung uses it in its Exynos processor. The problem is in the version of Mali GPU used by MediaTek. It uses older versions of Mali GPU which could not provide a competitive edge to other GPUs available with other processors. The same story is for PowerVR GPU used by MediaTek for a few of its high-end processors.

Qualcomm Snapdragon Gaming

While on the other hand, Qualcomm manufactures its own GPU units named Adreno. They perform far better as they get better tweaks to run efficiently with Snapdragon processors. So, Adreno GPU's, which are although less clocked than MediaTek's Mali, perform far better and give more realistic graphics texture. Also, as said, Qualcomm focuses much on development, so game developers love to make games for Adreno GPU's. This is because developing games and software for Adreno GPU's are a lot easier than making a game for a Mali GPU.


Developers' Choice : Android Development

Snapdragon Camera Firmware

Qualcomm is very much interested not only in tweaking its hardware but also in the development of compatible software for it. It provides source codes for the drivers and firmware of its SoC's and also updates them periodically. And because of this, Qualcomm devices (smartphones) are more developer friendly and get many custom ROMs, custom recovery, custom kernel and lot many tools for them. Sometimes, Qualcomm smartphones keep getting latest versions of Android by unofficial developers, even if the OEM has stopped providing updates to them.

However, this is not the case for MediaTek SoC's. MediaTek is not much interested in software development, nor does it provide source code for most of its processors. And this is why MediaTek devices only get to ROM ports from other MediaTek devices and rarely get new Android versions from unofficial developers.

This is the reason developers prefer Qualcomm processors over MediaTek.


Price : Cheap vs Expensive

Snapdragon Phones

MediaTek processors are known for their low price. This was probably the reason for its success in last few years. As MediaTek processors were cheaper they provided value for money in the budget and mid-range smartphones. Also, another reason was that the cheaper processors provided by Qualcomm at that time were utterly useless.

But at present, there are many good budget Qualcomm Snapdragon processors available with good features and specs. Although similar priced MediaTek processors look good on paper, but Snapdragon beats them in end-user experience even in budget range smartphones. So, many of the bigger players of smartphone industry are choosing Snapdragon processors for their budget range smartphones.

However, we have to say that, if you are going to buy a smartphone of around $100 or above you must look for a Snapdragon processor. But for even a lower budget you can go with a MediaTek one.


Final Verdict

Qualcomm Snapdragon

I am neither against MediaTek nor am I a Qualcomm lover. All my opinions are based on data and reviews available online about these processor brands accompanied with my personal experience.

So, what processor to choose depends on what are your preferences and budget. If you have a very less budget and want a phone for basic use like phone call, surfing etc. then you can go for a MediaTek processor. But if you want an all-rounder smartphone with good performance and best battery backup and want lasting software updates and development, then you should choose a Qualcomm Snapdragon processor.

If you are planning to buy a high-end or a flagship smartphone, then it is not recommended to opt for a MediaTek SoC. Even choosing MediaTek for a mid-range smartphone cannot be seen as a good decision.

So, I recommend Qualcomm chipset over MediaTek as it will disappoint you less.

Q. How to enable Google Search widget in recents in QuarkOS 3.0?

Ans: In QuarkOS 3.0 you may find that Google Search widget has been removed from recents screen. This happened because Google Search got embarrassed because of awesome unified search widget of Evie, just kidding :p

So, to get it back install Google Now launcher (or any other) and then make it default and disable Evie launcher from Settings.

Then reboot your device. You will see that Google search in recents will come back happily.

Then you can revert back to Evie launcher.

Bugs and Workarounds

Known bug: Led notification light not working for notifications when charger is not connected. [But works with USB plugged]

Workaround: Use Light Flow Pro app (or LED Blinker app) to set led notification for your favourite app. Set the LED to “Always on”.

Limitation: Since the ROM is fully based on AOSP, there is no native support for NTFS and exFAT file systems.

Workaround: Use Paragon NTFS, ExFAT Mounter app from Google Play.

Some Tips

The ringtones are set to 'none' by default. So select your favourite ringtone after flashing. ("Sound picker " app is preferred)
Use Xperia Camera Widget to access all the Camera addon apps.

For Devs and Advanced Users

After hours of hardwork I have finally made patchable source of QuarkOS. Here it is:

https://github.com/QuarkOS-ROM

This source contains all the history of methods that I used to make the ROM.

Now Devs of different devices can try making with different bases like MM, N, MIUI, Lineage etc.

Now users can know the secret of making ROMs by modding. And there's lot to learn.

I hope to see QuarkOS for other devices too. :)

How to Choose Best Headphones by Looking on Specs

Headphones

How to choose best headphones on the basis specifications • Earphones Specifications Explained • How to know if headphones have good Bass, Clarity and Treble

There are variety of headphones (or earphones) available that it becomes difficult for us to choose the right one that suits our purpose.

We may sometimes find that a budget headphone may give a better output than a costly one. This is because everyone’s taste is different, some people like bass and some treble, some love loud music and some people love soothing music. So every headphone may not suit everybody.

So how to choose which headphone is best for you. For that first let’s discuss the different types of headphones and their features. Later on we will discuss in detail about different specs of a headphone like frequency range, sound pressure level, impedance etc.

Types of Headphones

There are basically three types of headphones.

1. On-ear Headphones

On-ear Headphone
On-ear Headphone
On-ear headphones or supra-aural headphones are those headphones which rest on the top of the ear. They are basically more light weight than over-ear headphones and are easier to carry. As they sit on the ears, there may be some leakage of sound and may not provide noise isolation as good as over-ear headphones. Sometimes they may be tight and my squeeze the ear too tightly to make it uncomfortable for you to use it for a long time. So, it is crucial to choose the correct pair that fits perfectly.

2. Over-ear Headphones

Over-ear or circum-aural headphones enclose the whole ear. So they are more comfortable for a long term usage. As they encase the entire ear, there is no leakage of sound so it gives better noise isolation. Also because of this bass is better in these type of headphones. Since they are bigger in size they are less portable than other type of headphones.

These type of headphones are further divided into two types:

Closed-Back Over-ear Headphone
Closed-Back Over-ear Headphone
Closed Back: These are most general type of circumaural headphones having the back of earcups sealed. Because of this it provides superior noise isolation and more clear audio.


Open-Back Over-ear Headphone
Open-Back Over-ear Headphone
Open Back: This type of over-ear headphones has the back of its earcups open. These type of headphones have more sound leakage but sometimes they are preferred by the audiophiles as they provide more natural sound, they feel.

3. In-ear Headphones

In-ear Headphone
In-ear Headphone
In-ear or canal headphones fit inside the ear canal. Since they fit inside the entrance of the ear, they provide better noise isolation and good quality music. These type of headphones come with different size of tips, so you need to choose the one which fits perfectly in your ear canal otherwise it may be loose and will reduce noise isolation.

These were the different types of headphones, now let’s discuss about the different technical specifications which we see on the box of headphones or on its site.


Technical Details or Specs

Frequency Range and Frequency Response

Human audible frequency range is 20Hz to 20KHz. Different headphones come with different frequency range (e.g. 17Hz – 22KHz, 20Hz – 22KHz etc.). While choosing a headphone it should be noted that lower the minimum frequency more will be the bass and higher the maximum frequency more will be the treble. And the response or output that we get at different frequencies is called frequency response. Some headphones contain a chart for frequency response. By studying the chart, we may understand about the output of the headphone.

Driver Size

Driver is the most important component of a headphone which creates the sound. It converts electrical energy into sound energy and has a diaphragm which vibrates to produce the sound. It is generally regarded that larger drivers produce better quality audio, but it is not a fixed rule. Size of a driver is measured by the diameter of the diaphragm in millimeters. So, a driver size of 40mm or above is good for an over-ear headphone. The in-ear headphones contain a driver of 8mm to 12mm. Some in-ear headphones contain two drivers, one for handling bass and other for mid and high frequencies. And some premium in-ear headphones contain even more than two drives.

Impedance

Impedance is the electrical resistance produced by a headphone. It is measured in Ohms. Headphones with higher impedance require more power. So, impedance is generally less (below 32 Ohms) in headphones designed for mobile devices. So, headphones for mobile devices use a low voltage and require a high current which sometimes creates a hissing sound. On the other hand, high-end headphones have a higher impedance (above 300 Ohms) which produces clear sound but require a dedicated amplifier to power them.
In some cases, impedance mismatch may also create sound distortions and noise. So, higher impedance headphones should not be used with smartphones and low end headphones should not be used with high-end audio systems and amplifiers.

Total Harmonic Distortion (THD)

In some headphones we may find some sound distortions at higher volume levels. This happen when the diaphragm could not vibrate as fast as required at higher volumes. This creates a sound distortion called Total Harmonic Distortion (THD). Most headphones have THD of less than 1%. Lower the THD better will be the sound output at higher volumes. So, many premium headphones have a THD of 0.5% or sometimes even up to 0.1%.

Sensitivity and Sound Pressure Level (SPL)

Sensitivity of a headphone may be described as its efficiency. Sound Pressure Level indicates the loudness of a headphone. SPL is measured in Decibel SPL per milliWatt. The SPL of most headphones is in the range of 85 – 120 dB SPL/mW. So, higher the Sound Pressure Level of a headphone, louder will be its sound output.

Noise Cancellation

Some headphones have noise cancellation technology. They have a dedicated microphone which records the ambient noise, then creates an inverse sound wave and feed it back into the headphones to effectively cancel out the noise. It works best for constant low frequency noise (like sound of the engine of an aeroplane) but does not work for higher frequency noise (like people talking around).

Noise Isolation

Noise Isolation means blocking external noise by the physical design of the headphone. As we have already discussed before, noise isolation is higher in in-ear headphones and over-ear headphones with closed back.


So how to make the choice?

Understanding a headphone configuration is a much complicated task. But still we may try to find the headphones that best suits our purpose by taking into account the above factors, our environment and the type of music we love to hear. People’s review of the headphone may also become an important factor affecting your decision.

How to Change the Icon of an Android App

There are millions of android apps in and around the web and each app has its icon. Every developer creates the icon of his app according to his suitability. But we do not find some icons interesting or they do not match to the theme of our android smartphone. So, is there any way to change those icons according to our choice?

The answer is ‘yes there is one very easy way’— APK Icon Editor.


APK Icon Editor

APK Icon Editor is an open source application by which you can edit your APK files downloaded from Google Play or from anywhere else. By using this application you can change the icon of your android app and do a lot of other things (which we’ll discuss later). APK Icon Editor also supports Kindle and Blackberry APKs. Thus, it is compatible with large number of devices. The only drawback of APK Icon Editor is that it is a Windows software so you cannot use it directly on your android device, you have to take help of your PC.

How to Change the Icon of an APK File

Now let’s move on to the main task – ‘how to change the icon of an APK file’. You just have to follow these easy steps:

  1. Download and install APK Icon Editor on your PC
  2. Backup the APK of your Android App using ES File Explorer or AndroZip or other.

  3. Android App with Original Icon

  4. Transfer the APK file to your PC or laptop.
  5. Open the APK file with APK Icon Editor software installed on your PC. You’ll see a window like below.

  6. Android app opened with APK Icon Editor

  7. Select the highest size of icon (here I select XXXHDPI). (You also have to change the ‘Device’ if you are using Blackberry or Kindle)
  8. Right click on the icon and select Replace Icon from the dropdown menu. Alternatively you can also use the shortcut key Ctrl+R.

  9. Android App - replacing icon in APK Icon Editor

  10. Then select the appropriate icon (the icon should of size 192x192 or more for XXXHDPI). If it asks for ‘Resize Automatically’, select ‘Yes’. The icon will be replaced with the new one.

  11. Replacing the icon of Android App

  12. Then you can either click on the button ‘Apply to All’ (to make all icons from LDPI to XXXHDPI of the current size) or you can manually replace the icons of all sizes one by one.
  13. Then click on ‘Pack APK’ button and transfer the newly generated APK file to your Android Device.
  14. To install this newly modified Android App you first have to uninstall the original app.
  15. Now you have successfully changed the icon of your android app.

Drawbacks of this method

  • You have to uninstall the original app to install this modified app; that means you may have to lose your previous data.
  • You will not get automatic updates to your modified android app. You have to manually download the updates from Google Play by uninstalling your modified app.

So, this method is not much useful for frequently updating apps (only if you like to update your apps). But this method is very useful for stable apps or some non-Google Play apps.

N.B.- Use this method for your personal use only.

What More You Can Do With APK Icon Editor

APK Icon Editor is a massive tool by which you can do lot more things. You can also change the name, version etc. of your APK file under the Properties tab. But for this you have to change the mode to ‘Apktool’ by clicking the ‘ZIP’ button in the upper right corner. With APK Icon Editor you can even explore APK contents and see or modify what’s inside your APK file.
