Qualcomm's Snapdragon 625 (MSM8953) processor started appearing in smartphones in the middle of this year. And at first we saw it in devices costing $ 300 and above ( Samsung Galaxy C7, Asus ZenFone 3, Lenovo Moto Z Play, etc.), and towards the end of the year it appeared in smartphones of a more affordable segment (Nubia Z11 Mini S) and even in the budget Xiaomi Redmi 4 Pro. The secret of this success of the Snapdragon 625 is the excellent combination of performance and energy efficiency, because it became the second Qualcomm chip in history after the flagship Snapdragon 820, made according to the norms of the 14nm process technology.
Since not everyone is ready or can spend a few hundred euros to buy high quality smartphone, here is a set of devices available for a budget revolving around 200 euros. With a leitmotif: the best quality software best price... A big trend throughout the year in terms of smartphones? A proliferation of new models in the middle range at an affordable price.
But, as in other areas, everyone is not equal. The devil lurks in technical files, the understanding of which is not available to all buyers. To help them, we therefore decided to clear those well-lit beams so that only the cream from the appliances was retained. In the bowels of the car, so that it does not disappoint with the speed of the display, the smoothness of navigation and that it does not pass too quickly, we have kept the models displaying at least 2 GB of memory, an eight-core processor and a promising battery in terms of autonomy. Finally, on the side of the main photosensor, all the smartphones of our choice accommodate at least 13 megapixels, which of course doesn't do everything, but allows us to offer an additional point of comparison.
As for the main competitor of Qualcomm, which is MediaTek, it has a chip similar in characteristics appeared only towards the end of the year. The Helio P20 (MT6757) processor, like the Snapdragon 625, is also designed for mid-range smartphones price segment... It is made according to the 16 nm process technology, becoming the first in the MediaTek line of such a modern and energy-efficient processor, and has a performance level comparable to its opponent.
Idol 3, released shortly before summer in the first version, clad in brushed metal, is now available with a real brushed aluminum shell that gives it a premium finish. We like it less: its non-removable battery. Its price: 16185 rubles, which falls to 14,235 rubles with an offer to return to the course for a purchase until November 30. The brand also offers Black Friday promotions.
It offers a beautiful 5-inch high definition scratch-resistant screen. We love less: the battery is not removable. 
Second year, Arcos surprises us. 
Its price: 12,935 rubles. Where can I buy? 
Its price: 199 euros for its launch a few months ago, its price fell between 140 and 190 euros in accordance with the shares.
Therefore, a quite reasonable question arose: "Which processor is better, Helio P20 or Snapdragon 625, and which solution should be preferred when choosing a smartphone?" And in order to answer it, we need to compare these two processors in terms of characteristics, test them in benchmarks and check how much they heat up during operation.

As you can see, Helio P20 and Snapdragon 625 are very close in specs. The chip from MediaTek has the advantage of maximum frequency cores and support for faster and more energy efficient modules random access memory, but there is also a weak point in the face of the video accelerator.
This may seem trivial to a less advanced person, but not at all. The lower the etching fineness, the less energy the processor will need, and especially its energy coefficient will be much better. These ten hearts will be divided, as usual, into three “blocks”.
There are also improvements in points. 
One thing is clear: middle class promises very interesting smartphones this year. In this article, we compare the specifications of two microcircuits, put them side by side in several benchmarks, evaluate the performance of computers and graphics, and check to what extent they lead to overheating of smartphone designs.
To understand the whole picture, you need to test both of these processors in benchmarks. And we will compare using the example of smartphones Xiaomi Redmi 4 and Meizu M3X (Meilan X).
In the AnTuTu benchmark, the Snapdragon 625 processor scored about 62 thousand points, while the Helio P20 showed almost 66 thousand points there.
If you are interested, you can check current price and the availability of two telephones used for this item. This layout is a clever way of balancing low power consumption and high performance - the first group tackles lighter tasks and uses other colors where needed. The table below shows the results.
The latter allows you to simulate several hours of play. Immediately after that, we measure temperatures in three sections of the back of the smartphone. However, the chip, even being the main factor, is not the only one that affects temperatures. More important here is that our degrees are acceptable. The pictures below show the temperatures recorded on the three parts of the back of each smartphone. Leaping into the next generation with a focus on all aspects of multimedia including video recording, cameras, gaming and connectivity.
In the GeekBench 4 benchmark in single-core mode, the results of both rivals were almost the same, but in the multi-core Helio P20 outperformed its rival by almost a third. At the same time, as expected, the Snapdragon 625 performed better in graphic test, although not much - by 13%.
In this article, we compare the specifications of the two chips, put them side by side in a series of benchmarks, evaluating graphics and processing performance, just as they achieve overheating of smartphone designs. If you are interested, you can always check the current price and availability of the two phones used for this item. This organization is a smarter way to balance low power consumption and high performance - the first group tackles lighter tasks and, if necessary, a different core.
When performing normal tasks, Helio P20 uses a bundle of 4 cores with a clock speed of 1.65 GHz, while Snapdragon 625 uses all 8 cores, but little by little. And when performing complex tasks, both chips use all their cores at the maximum frequency. In other words, the algorithms of work Snapdragon processors 625 and Helio P20 are different depending on the load level, but it is impossible to say for sure which one is more energy efficient. These are the best energy efficiency solutions for each of the chip makers, and in the end everything will come down to optimizing the end device.
The latter allows us to simulate hours of play. Immediately after that, we measure the temperature in three sections of the back of the smartphone. In any case, although it is the main one, it is not the only factor affecting the temperature. The most important thing here is that the degrees are acceptable. The photo below shows the temperatures recorded in the three sections of each back of the smartphone. One more example standalone smartphone... This solution saves something on the cost of the phone, in this case it sells for 499 euros.
This way, you can be sure that you will take a sufficiently detailed photo without blurring the subject in it. Some of these smartphones are already present in the site's video reviews, thanks to which you know them well, others are not. The Korean giant has already invested huge amounts of money to officially launch the first foldable display smartphone. The official premiere will take place in the first months of next year. Of course, the device will be sold in limited quantities.
And what about the heating of these processors? Measurements have shown that both Helio P20 and Snapdragon 625 have excellent heat control. During testing, none of the smartphones got hotter than 35 degrees Celsius, which is a very good result. Of course, the design of the tested smartphones and their cooling systems played a role here. But overall, the end result was the same.
It's no surprise if smartphones with foldable displays become a reality in a few years. It will be interesting to see how the competition develops between them in this emerging market niche. See when foldable displays become a reality. But the partnership between the two companies is coming to an end, which is quite surprising. The collaboration between the two companies could turn the Model 3 and its successors into an even more compelling choice for consumers. The smarter modern cars, the more interest they will be to the biggest names in the tech industry.
Thus, we cannot answer unequivocally which of the processors is better. The Snapdragon 625 is a little better suited for those who like to play graphics-intensive games on their smartphone, though not at maximum settings, if we talk about games like WoT. Not at maximum settings, you can play on a smartphone with Helio P20. And with everyday tasks, both Helio P20 and Snapdragon 625 will cope with a bang, having a good groundwork for this for a couple of years to come.
Ten technologies that are good for future cars. These architectures offer an impressive combination fast speed and low power consumption. Due to the huge popularity of these mobile gadgets, we also have a large number of processors.
The answer to this question is not easy. It is clear from the outset that the following statement is subjective. Of course, the basics are based on the performance of each chip, but we also considered their popularity, as well as our impressions of individual smartphone tests and their availability.
Smartphone up to PLN 700 - which processor?
The decision on a flagship smartphone is hard to expect compromises. No wonder he came. And here, however, 14nm processing technology and four cores were used, but with a slightly lower clock. Until recently, this was the processor available on much more expensive smartphones, but nowadays there are more and more guests in models that are somewhat more affordable, for example. It is widely used by manufacturers in budget smartphones. We think you may have a different opinion. Remember what was mentioned in the introduction.
And summing up this article, we can finally say that MediaTek has managed to release a more or less equivalent product to the Qualcomm processor, albeit so far only in the segment of the middle and mid-budget classes. Let's hope this trend continues. And we have every reason to count on this, because Helio X30 with PowerVR graphics, which will debut in early 2017, should fight on equal terms with the flagship Snapdragon 820 and 821. But then the Snapdragon 835 will be released and Qualcomm will again break away ....
This claim is based on more than just performance. Share your suggestions in the comments. Currently on the market mobile communications there are a limited number of smartphones with two cameras. Manufacturers work hard enough to use a lens to deliver the best image quality, but this is why dual camera phones are the future of smartphones. No matter how clear and clear the image is from the lens, the dual camera makes the image brighter and more detailed.
And since dual-camera phones have not yet entered the mobile industry, it's okay to keep prices higher than those with a single lens. Today we would like to introduce you to the 5 best budget phones with two cameras.
The prevailing stereotypes do not always correspond to the truth, which is why it is especially important to dispel some myths about mobile processors.
To a question " Which mobile processor better?”Must be approached in detail.
Of course, we do not choose a smartphone solely because of the processor, other filling is no less important. However, without the competent packaging of the chipset and other components, even the top-end and most productive mobile processor can literally turn out to be useless.
A second camera sensor is used to measure depth. Its dimensions are 89 x 30 x 60 and weighs 00 grams. The phone's sensors include a compass magnetometer, a proximity sensor, an accelerometer, a light sensor, and a gyroscope. The panel itself offers good viewing angles and the reproduction of colors and brightness levels is adequate.
There is a fingerprint sensor on the back. The shape and layout are ergonomic, making them easy to use. One has a color sensor, while the other is used for monochrome data, which when used in tandem provide better image quality and less noise when using low light images. The front 8MP camera is decent for itself in good light but not much under artificial or low light.
We hope that our excursion into the world of processors and their manufacturers will be useful for you.
Terminology
Usually, the concepts "processor" and "chipset" are taken as synonyms, but this is not completely true. Modern mobile processors are part of SoC(System on Chip), on which other elements are located.
Outwardly, the chipset is similar to the old-style processors, but in essence the chipset is a platform for placing components, some of which are responsible for graphics, sound, orientation in space, etc, and the processor itself is just one of the components.
For example, schematically a chipset Snapdragon 820 looks like this:
Which processor is the best?
The answer to this question will logically differ for different categories of users.
Some users want to squeeze the maximum out of the smartphone, using the device not only as a dialer, but also as a game center. Sly marketers have found a loophole on how to attract the attention of just such an active type of user and at the same time save money - equip a smartphone with a 4-, 8-core processor, but with minimal clock frequency.
In this case, not an expert in the field mobile phones sees a tasty line in the specifications for an 8-core processor and considers the device to be very productive by default. But actually a 4-core processor with high core clock speeds easily outperform some lower clock 8-core processors.
But knowledge in the field of processor frequency does not guarantee correct selection gadget.
Hidden characteristics
There are hidden characteristics about which information is sometimes very difficult to find.
Important is technological process by which the processor is executed. Roughly speaking, the process technology is an indicator of the size of the transistors, of which the processor is made up of millions. Accordingly, than smaller this indicator, the more they can be placed on the crystal and themes faster the filling works. The technical process is measured in nm (nanometers).
At the moment, the most common technical process is 32nm. Some flagships, which are planned to be released in the next few years, will receive processors with a much smaller technical process.
In particular, the processor is preparing for release MediaTekHelio X30, the undoubted advantage of which will be the use of 10nm FinFET process from TSMC.
Besides, Helio X30 equipped with top cores, in particular, two ARM Artemis (2.8 GHz) computing cores are installed, which have already been dubbed the main rivals to the Kryo cores from Qualcomm. The chipset also includes the well-known four Cortex-A53 cores (2.2GHz) and the same amount of Cortex-A35 (2GHz).
The first devices with this processor will be presented only at the beginning of 2017.
But this is just reference point rather than 100% evidence of processor performance.
Specifications: de jure and de facto
A case in point is the iPhone 6, which received 2-core Apple A8 with clock frequency 1.4GHz... Do not forget about another important factor - RAM. With its insufficient quantity, even the most top-end processor will obviously not be able to fully express itself.And in the case of the iPhone 6 on board, only 1GB RAM. Modest performance, isn't it?
Especially against the background of many Chinese devices, they are much cheaper and with more tempting indicators - for example, Xiaomi Mi3 who received 4-core Snapdragon 800 core clock 1.7GHz and 2GB RAM it seems much "tastier" than the apple set in the paragraph above.
The myth about the importance of numbers in the specifications will quickly dissipate, you just have to try both smartphones “in action”. The secret lies in optimization.
Apple's software optimization is much better than Android devices, where the focus is on the attractiveness of the numbers.
You should also be careful with the amount of RAM. The newer the firmware installed on the smartphone, the more voracious it will be. For example starting with Android version 4.2.X, the minimum amount of RAM to ensure stable operation is 1GB, but already for Android 4.4.X, the starting value of RAM for full functioning has increased to 2GB.
But even if the user carefully studied the number of cores, their clock frequency, technical process, the ratio of the processor and the rest of the filling, appreciated the optimization of etc, there remains such a factor as peculiarities each processor.
We'll talk about the individuality of some chipsets a little later, but for now, here's a list of top processor manufacturers:
Qualcomm- the company, deservedly received the title of one of the best among the processor manufacturers, however, the cost of the chipsets of this company is usually overstated, in comparison with the pricing policy of other brands.
MediaTek- main Qualcomm competitor... Initially, the company focused on the production of processors for budget smartphones, but at the moment the situation has changed - just remember the line of processors Helio... A strong advantage of the company is much more affordable prices for processors than Qualcomm.
Intel... The company's success in the field of mobile processors is much more modest than in the production of processors for computers. For mobile devices the company launched the Atom line, which received its distribution mainly on devices from Lenovo. There are a number of other smartphones lurking under their hood Intel Atom , but their number is so small that it hardly makes sense to talk about this series of processors as a serious rival for the two companies described above.
Samsung- a company that produces a fairly successful line of processors Exynos... But as is the case with Intel, Exynos is installed on a small number of phones (mainly on smartphones of their own production).
nVidia is the least known processor manufacturer. Manufactured series of processors Tegra not in demand and installed on a very narrow range of gadgets. An attempt to enter the international market was made in 2012, when the manufacturer released the 4-core Tegra 3. But soon a serious flaw became apparent: severe overheating.
The most interesting is the confrontation Qualcomm and MediaTek... And for the right choice smartphone, you need to know some of the features of the processors produced by these two giants.
Snapdragon 820- the sensational “hot” processor from Qualcomm. The “hot” novelty was installed on a variety of smartphones - Xiaomi Mi5 Pro, Leagoo Elite Pro, Doogee F7, Elephone P9000, Meizu MX6, LG G5, etc.
Similar to the situation with Tegra 3, users are faced with strong overheating of their favorites. Remarkably, the 820 Snapdragon was released as a replacement for the 810, which is also prone to overheating.
This failure gave other manufacturers an opportunity to prove themselves. In particular, one of the main competitors of the Snapdragon 820 is Exynos 8890... An interesting decision was made regarding the Samsung Galaxy S7 and S7 edge. Smartphones are released in two versions: for residents of China and the United States, a version with Snapdragon 820, and for the domestic market and Europe, a variant with a branded Exynos 8890.
AnTuTu results show leadership in terms of performance Snapdragon 820.
But in multi-core mode Geekbench shows primacy Exynos 8890 .
Purchase cost Snapdragon 820 is $ 70, which greatly affects the final price of the smartphone. For a much smaller amount you can buy Helio X20($ 30), which has almost the same performance as Qualcomm's 820 processor. Naturally, devices running MediaTek Helio X20 will be much more affordable.
That is why users should be careful when buying a device and objectively evaluate the ultimate goals of using the device: if your priorities do not include spending time with toys, then it makes a lot of sense to pay attention to smartphones with a processor from MediaTek. Especially well proven MT6753.
However, MediaTek is gradually shaking off its reputation as a brand that produces chipsets exclusively for state employees - the aforementioned Helio X30 direct evidence of this.
A few words about synthetic tests
The fact is that the test results in AnTuTu- just a rough estimate of performance, but not an accurate representation of reality.
The results of the same device change frequently after a firmware change. Also, the optimization of the hardware and software part of the smartphone plays an important role.
Manufacturers often try to cheat and artificially cheat values in tests. In 2013, a scandal about cheating broke out Samsung in the AnTuTu results. The company's engineers came up with a trick: when launching AnTuTu graphics processor Samsung S4 automatically switched to high frequency mode (from 480 to 532 MHz), which is why the results increased.
In the same year, accusations of dishonest results went to the company. Intel... Some analysts agreed that AnTuTu is optimized for Intel Atom, so the results in this test will be somewhat overestimated.
It makes sense to compare virtual parrots AnTuTu exclusively within the same platform. There are other applications for cross-platform comparison, the most popular of which are Geekbench and GFXbench... In any case, you need to understand that the indicators obtained only roughly reflect the capabilities of the smartphone.
Conclusion
To choose the most optimal smartphone it is necessary to approach in a comprehensive manner, relying not only on tasty numbers, but also figuring out what is really behind them and whether it is worth the money.
There is no point in overpaying for a top-end multi-core processor if it will be used only for basic functions. But you shouldn't rely on luck that a mediocre chipset will overpower top toys.
Command b ad-android wishes you only successful and pleasant shopping!
Stay tuned ahead many interesting.
