Smartphones with the qualcomm snapdragon 636 processor. Everything is like in a cool processor, but in small doses

I don’t know why, but I don’t like talking about new processors or technologies. When I asked myself the question why it really is, I could not find the answer for a long time.

Snapdragon 636 will dominate Mediatek!

It will be so! Let us remind ourselves why the 625 was and is such a popular processor? First of all, the price. The product from Qualcomm just ate a competitor represented by Mediatek. In particular, smartphones from Xiaomi, which was extremely large for one manufacturer. The Chinese giant has signed an agreement with Qualcomm to clean the warehouses from this processor.

Everything is natural. The price of the final product is the same as the price of the product from Mediatek. But the speed, autonomy and GPS are better.

What does the Snapdragon 636 offer?

The processor is built on ARM Cortex technology with independent clusters. Each of the clusters optimizes its work in such a way as to do as much work as possible in the shortest possible time. Thanks to them, this processor should be 40% more efficient, from Snapdragona 630. A very big plus in the piggy bank.

GPU Adreno 509 - The latest chip is equipped with strong graphics. The 6XX series, in my opinion, is the best on the market. Here is a new generation. The manufacturer promises a more efficient rendering of advanced 3D graphics.

Qualcomm Spectra ISP - The 14-bit Spectra 160 should provide photo matrix support of up to 24 megapixels and almost zero shutter lag, fast autofocus, smooth zoom and bright black.

Snapdragon X12 LTE - The Snapdragon 636 is a kind of attempt to exceed the threshold from 4G to 5G. However, this is not the pioneer of this decision. Huawei Mockups - Kiriny serves much higher speeds. For accuracy, 636 supports speeds of up to 600 Mbps. Unfortunately, we are not much use for this. For now...

Qualcomm Quick Charge 4.0 - This is what seems most interesting to me personally. Phones are getting faster. However, when it comes to batteries ... well, technology doesn't move ... almost. This is still a huge problem in smartphones. These shortcomings make up for fast charging! Version 4 is faster than version 3.0 by 20%. This may seem small, in the case of the battery, however, the differences are significant.

636 will go for Redmi Note 5?

A lot of this indicates. The main argument is the fact that this chip supports FullVision-sized screens, i.e. other 18: 9 formats. this is exactly the screen that Xiaomi Redmi Note 5 will get. Only one thing surprises me ... how will they be in time? The premiere of the new Redmi should take place this year. And when does Qulacomm start shipping its processors? The first deliveries will appear in November, so that smartphones will appear in large numbers in the second quarter of 2018. How will Xiaomi solve it? Can we get it again on the 625-ke?

Xiaomi has signed an exclusive contract for the purchase of processors from Qualcomm in huge quantities. The company plans to sell up to 90 million smartphones this year. The situation should be repeated, as with the history of Snapdragon 625. Note 5 is on the way, so everything hints to us that Xiaomi will be the first to receive this processor with its Xiaomi Redmi Note 5.

What do you think of the Snapdragon 636 processor? I got the impression that Qualcomm brings a little too much new processors to the market. I myself am already lost in the 4xx and 6xx series. Only the 8xx series is transparent since only up to 2 processors are released during the year.

What is what?

It is amazing how many people still believe that all the technical specifications of the smartphone entirely remain on the conscience of its manufacturer. As if any conditional Xiaomi or ASUS can “sprinkle” as many gigahertz, gigabytes and megapixels as you like, and when something starts to miss, all the people's anger goes to the manufacturer itself. Of course, this is not so. Almost any company today selects several key components from other manufacturers, combines them, assigns a name and sends it to the market. First, a system-on-chip (or just SoC) is selected, which includes the central processor, graphics accelerator, RAM, navigation module, and modem. Then it comes to choosing a camera, screen and battery, but here it will already be limited by SoC capabilities. On the one hand, all this looks gloomy: the lack of freedom of choice, similar to water drops of a tube with identical capabilities and the same prices. But on the other hand, today a full-fledged manufacturing company can consist of a couple or three people at one table in a modest room of a Class B business center. In other words, it has never been easier to start changing the world for the better. Well at least the world of mobile gadgets.

Of course, there is an exception to any rule. In the world of smartphones, it's Samsung. The company uses its own processors manufactured in its own factories, puts its own screens and batteries. But even Samsung can be called an exception with a stretch, because its smartphones often have cameras made by Sony, and in the USA the latest generations of Galaxy S and Galaxy Note came out on Qualcomm Snapdragon, and not Samsung Exynos.

Qualcomm is, of course, the largest and most visible player on the mobile platform market, but Mediatek is actively competing with it, which supplies platforms to everyone, as well as Apple, Huawei and Samsung, which cover their own needs for SoC on their own (he looks at the same Xiaomi, but so far the company has only one platform and one smartphone based on it). In fact, production takes place at Samsung and TSMC factories, and in the vast majority of cases the same ARM Cortex are used as cores. Even processors for the iPhone are manufactured at Samsung and TSMC factories. And all systems-on-chips for budget and medium-sized devices have been using the same cores for many years in a row, albeit in different quantities, configurations, and with different frequencies. Qualcomm, by the way, was no exception, but this year the situation began to change for the better. The announced Snapdragon 636 is one of the first SoCs to abandon the ubiquitous Cortex-A53 and migrate to the more powerful Kryo cores. Well, the platform specifications will now allow us to speak with high accuracy about what smartphones will be next year. And now I will explain why.

Snapdragon 636 and the near future of low-cost smartphones

	Snapdragon 636	Snapdragon 630	Snapdragon 660
Process technology	14 nm	14 nm	14 nm

Charging	Quick charge 4	Quick charge 4	Quick charge 4

The composition of any modern SoC includes many different components. This is not only the CPU and GPU, but also additional computing subsystems, modems and all wireless modules. And Qualcomm even offers a reference camera with a separate processor for processing the signal from the matrix. But, apparently, the default camera quality does not suit manufacturers, and most prefer OmniVision or Sony modules. With a huge bias towards the latter.

Returning to Qualcomm, it is worth explaining that the company has a clear division of SoC into flagship (8XX line), budget (4XX line) and medium-sized ones, which include the Snapdragon 6XX series in general and the freshly presented Snapdragon 636 in particular. SoC Snapdragon 660 and 630 were introduced a little earlier, the new modification in performance will be located exactly between them. There are not so many smartphones using the new generation Snapdragon 6XX - for example, ASUS Zenfone 4, Motorola Moto X4, Oppo R11 and Xiaomi Mi Note 3. They use Snapdragon 630 and 660. Snapdragon 636 is an absolute novelty, but Qualcomm says. that several contracts have already been signed and the first smartphones based on this platform will appear on the market at the beginning of next year.

As for performance, there is no data on the results of the usual benchmarks yet, but Qualcomm has already calculated everything: the 636th will be 40% more productive than the 630th and about 20% slower than the 660th.

In general, I would not say that there is something really amazing in the specifications of the new platform, but one small detail perfectly matches the spirit of the times. The new platform supports displays with a resolution of FHD + (2160 × 1080 pixels, aspect ratio 18: 9), and this should encourage manufacturers of low-cost smartphones to adopt the main feature of this year's flagships, namely the frameless design. This aspect ratio will allow more rational use of the front surface of the smartphone and make the frames thinner. Well, then this is very logical - middle-class devices over time acquire chips of higher-class devices. And this happens not only in the case of smartphones, but also in general with any equipment up to yachts and cars. Higher resolution, including in the 18: 9 format, at the moment can only be implemented on more expensive platforms: Snapdragon 660 and 835.

And the last thing to keep in mind when talking about the Snapdragon 636 is support for the next generation fast charging, Quick Charge 4, and the built-in Snapdragon X12 modem, which supports downloading data at a maximum speed of 600 Mbps. This is far from even the maximum potential of LTE, and yet it is at this point that we should go on to talk about the increase in speed with the deployment of fifth-generation networks.

Migrate to 5G and Qualcomm Snapdragon Notebooks

Current devices based on the top-end Qualcomm Snapdragon 835 officially support downloading data over LTE at speeds up to 1 Gb / s. But firstly, we are talking about peak, not average speed. And secondly, this is possible only if there is support from the operator and the readiness of the appropriate infrastructure. In total, 38 operators in 23 countries boast such speed in the world, including the USA, Canada, Japan, China, South Korea, Australia, Indonesia, New Zealand, most countries of Western Europe and Russia. True, with us this is only possible for MegaFon subscribers in Moscow so far.

If we talk about the peak speed, then at the very beginning of the development of 5G it will be about 1.5 Gbit / s, and the average connection speed will be approximately equal to 1 Gbit / s, so the transition process will be quite smooth. The first users will not feel a drastic decrease in speed when the smartphone switches to 4G mode.

According to Qualcomm, the volume of monthly mobile traffic from 2010 to 2022 will increase by 650 times, and the peak data transfer rate for the same period - by 250 times. Most of this traffic is now streaming video. For example, in the United States, about 35% of mobile traffic comes from Netflix alone.

In mobile networks of the near future, smartphones and tablets will not be the only "transmitters" of data. As the Internet of Things, smart cars and urban infrastructure evolve, so will the need for network bandwidth. Transport, smart home systems, courier and consumer drones, street lighting systems - all this will certainly be connected to the network. And this fact once again makes us think about the meaning of the existence of such an atavism as a SIM card. Operators would be delighted with the idea of \u200b\u200bequipping each pillar with a separate card and lifetime binding to their billing system, but everything goes to the point that physical SIM cards will be replaced by eSIM. However, devices with their support exist now. This, for example, the latest generation of Apple Watch and iPad tablets, but operators still hinder progress in this area. However, the main motivators for the early spread of eSIM will be just miniature devices (like the same smart watches), in which there will physically be no place for carrier cards.

Qualcomm is also in favor of the speedy implementation of eSIM. At the same 4G / 5G Summit in Hong Kong, the company revealed some more details about the upcoming Snapdragon laptops. Talk about this has been going on since the end of 2016, and December 2017 was originally called the likely date for such devices to enter the market.

Now only Snapdragon 835 satisfies the system requirements of Windows, but towards the end of the year Qualcomm will hold another event, which will present the new generation flagship platform. And then we will have more details on how a full-fledged Windows on a mobile platform feels, as well as which manufacturers will join this idea. So far this is only ASUS, Lenovo and Microsoft itself. So, it is expected that all such laptops will connect to 4G networks without a physical SIM card.

The main idea of \u200b\u200bporting Windows to the Qualcomm platform is extremely simple - this is the only way to drastically extend battery life. How much can a traditional laptop work in active mode today? Well, if 8 hours, but in the general case even less. A laptop on an ARM platform (in this case, from Qualcomm) is already capable of delivering 28-29 hours of video streaming from Netflix, while for some models the figure can reach 36 or even 48 hours. This means that next year we will be able to go on short business trips, leaving the charger at home. Well, the question of how well Qualcomm-laptops will cope with the "difficult" tasks like batch processing of photos and video editing, we will leave open until the announcement of the new flagship platform Snapdragon.

It is very unusual to talk about stagnation in smartphone processors. “But is this stagnation?”, Ask the owners of computers, for which Intel almost lounged and gave “as much as 5% speed increase” once a year, while the only competitor, AMD, was hopelessly behind. "The reviewer is stuck or does not know what he is talking about!", Owners of Xiaomi smartphones are chanting and brandishing the results of benchmarks. And I do not argue that tsiferki in measuring the speed of work are growing year by year. The problem is that the processors in non-flagship mobile phones are similar to each other, like the tariffs of the "big three" mobile operators in Russia, and are just as rotten in their essence.

You buy, for example, cat food, and look at the packaging of Friskies, Felix, Purina ONE and Darling ... and this is all the work of the same Nestle concern, which slightly changes the recipe, twists different advertisements for different feeds, and packs these varieties into different packaging. There are even fewer differences in smartphone processors.

For a long time there was no reason to talk about innovations in low-cost processors. Now it is

Firstly, because all smartphone processors (systems on a chip, in scientific terms) are produced at the same TSMC or Samsung factories. That is, on the same “machines” chips are stamped with minimal differences, and then they leave for customers and get HiSilicon, MediaTek, Qualcomm or Samsung stickers. About how different the final price of a smartphone with the same processor can be, you already know.

Secondly, even the “recipe” for creating a smartphone chip for different manufacturers is the same indecently. Every smartphone manufacturer buys, relatively speaking, “drawings” of processor cores from the British company ARM (did you see the word “Cortex” in the processor description? That's it!). And then it’s just determined how much these kernels should be “cracked” so that the smartphone does not overheat, does not explode, and the buyer doesn’t get too good a cheap smartphone - otherwise it will not work out to spin it up for a new purchase.

Manufacturers order graphics (analogous to a video card) from the "half-dead" Imagination Technologies (PowerVR), but rarely. Or, almost always, the same ARM (Mali), that is, they do almost nothing with their own hands. And in low-cost smartphones, the situation looks even more dull.

King Cortex-A53 and no power interchangeability

To understand how everything is launched with mobile chips, let's return to 2014. From the speakers and cell phones in the streets playing Pharell williams , Russia hosted the Olympic Games, iPhone 6 and Samsung Galaxy S5 - the latest and coolest smartphones. And the quad-core Snapdragon 801 processors are the best among all the chips in android phones.

But there are a limited number of flagships, and give people cheaper smartphones. Therefore, “our everything” in the smartphone hardware, Qualcomm and MediaTek, “give birth” to processors with eight new economical cores, Cortex-A53 (Snapdragon 615 and MT6752). This filling, if you remember, was in the first generation Samsung Galaxy A7, Honor 5X, ASUS ZenFone 2 Laser and other rare minerals nowadays. Smartphones, which in translation to the modern rate would cost 23-30 thousand rubles.


Chipset	Snapdragon 615 (MSM8939)	MediaTek MT6752
Year of issue	2014 year	2014 year
CPU	8 cores (4x Cortex-A53 1.7 GHz + 4x Cortex-A53 1.0 GHz)	8 cores (8x Cortex-A53 1.7 GHz)
Video accelerator	Adreno 405	Mali-T760 MP2
RAM	LPDDR3, 800 MHz	LPDDR3, 800 MHz
Wifi		802.11n
Bluetooth	4.0	4.0
	150/50 Mbps	150/50 Mbps
Process technology	28 nm	28 nm

The initiative turned out to be so successful that the creators of the processors “continued in the same vein” and began installing the same inexpensive processors in expensive smartphones as early as 2015. For example, HTC wanted people to pay 40 thousand rubles for One A9 based on Snapdragon 615 and with a dead battery for 2150 mAh (do not laugh, these are the characteristics). Huawei for the flagship Mate S based on a processor with the same eight cheap cores (but already in Kirin 935) asks for more than 40 thousand rubles. This was the period of the most arrogant swindle, when low-power stuffing was sold at flagship prices.

The same Cortex-A53 cores wander in mid-range smartphones since 2014

Only in January 2016 Xiaomi replaced the greedy competitors and installed Snapdragon 616 (a slightly accelerated processor of the 2014 model) in the cheap Redmi 3 smartphone. A year after the adventures of smartphone manufacturers, the processors finally found their place - in the fastest budget phones.

Based on this tragedy, Qualcomm made really new, very powerful Snapdragon 650 (4 Cortex-A53 cores + 2 new Cortex-A72 cores) and 652 (4x Cortex-A53 + 4x Cortex-A72). The processors were cool for their time - powerful, modern, created according to the patterns of the flagship Snapdragon 810 (2015), but with less heating and power consumption. Only here the prices for almost all models with them were inadequate (LG G5 SE for 50 thousand rubles, HTC 10 Lifestyle for 45 thousand rubles), they only went to the people with the Xiaomi Mi Max and Redmi Note 3 Pro smartphones and almost all the latest did not meet.

Truly new and powerful Snapdragon 650 and 652 processors went to the people with Xiaomi Redmi Note 3 Pro and Mi Max

Since then, Qualcomm has returned (and MediaTek, Samsung Exynos and Huawei HiSilicon have not stopped) to operate the three-year-old Cortex-A53 cores in overclocked mode. Acceleration (increasing the frequency, the number of gigahertz) with the transition to a new manufacturing process (from 28 to 14 nm) and new “machines” of production was easy. With a thick layer of chocolate overheating protection and reduced power consumption, all eight cores were overclocked to the limit (the difference in benchmarks became almost twofold) and a new, twice as fast video accelerator was installed. This miracle is called Snapdragon 625 and, like Ivan Urgant, takes part wherever it is necessary, and where it is not necessary either. In versions with overclocking (Snapdragon 626), or new “Wi-Fi bluetooth”, a 4G modem and RAM (Snapdragon 630), it is still installed in the expensive smartphones (ASUS ZenFone 4 for 33 thousand rubles, Motorola Z2 Play for 35 thousand). Selling a morally obsolete design for many years with little or no change under the slogan "you will not go anywhere" is a very Russian tradition. It is strange that it was adopted by the American Qualcomm, the Korean Exynos (models 7880) and the Chinese HiSilicon (a circus with an attempt to "pull" the budget Kirin 650 to the middle class continues in Kirin 655 and 659). MediaTek also plays the fool, but it can be justified for the scandalously low prices for the 10-core powerful Helio (owners of Xiaomi Redmi Note 4 and Meizu MX6 / Pro 6 know what it is about). Even taking into account the fact that the Chinese chip maker had to cut prices not from a good life.


Chipset	Snapdragon 450 (SD450)	Snapdragon 630 (SD630)
Year of issue	2017 year	2017 year
CPU	8 cores (8x Cortex-A53 1.8)	8 cores (8x Cortex-A53 2.2 GHz)
Video accelerator	Adreno 506	Adreno 508
RAM	LPDDR3, 933 MHz	LPDDR4, 1333 MHz

Bluetooth	4.1	5.0
Maximum performance in LTE networks (download / download)	300/150 Mbps	600/150 Mbps
Process technology	14 nm FinFET	14 nm FinFET

I hope that you did not fall asleep from a long and tedious introduction, but otherwise I could not explain why the new 636th chipset is so important.

For those who asked "even cheaper!"

From the previous paragraph, you already realized how dreary the situation with processors at the level “slightly above the economy class” has become, so everyone expected from the “Big Two” (Qualcomm and MediaTek) breakthroughs, surprises and so on. MediaTek was waiting for the next seasonal sale of the flagship 10-core Helio, now the Helio X30 with a modern process technology (less heat and more efficiency, rather than in the Helio X20 / X25), so that they again began to appear in affordable mobile phones. But it didn’t happen - Meizu Pro 7 Plus based on such a Helio even in China costs 25-30 thousand, for which you can buy a real flagship smartphone with the “best of the best” Snapdragon 835.

Qualcomm enthusiasts believed when the announcement of the Snapdragon 660 took place. "Finally, they will give us the performance of last year's flagships at a low price!", Rejoiced geeks. And partly these forecasts came true if we are talking about ordering mobile phones from China - Snapdragon 660 started installing ASUS ZenFone 4 ZE554KL (28 thousand rubles) and Xiaomi Mi Note 3 (23 thousand rubles) - reference mid-range smartphones with a good camera.

For six months, smartphones on the new Snapdragon came out a little, but this is only the beginning

But the beautiful replacement with the ghosted “8 Cortex-A53 cores and dead graphics” that have been haunting us since 2014 did not work out of Snapdragon 660 - in Russia ZenFone 4 with Snapdragon 660 passes well for 30 thousand, and Mi Note 3 is not even going to sell, because "it will turn out too expensive, they will not buy." Whether this eight-core miracle will fall into the future Xiaomi Redmi Note 5 is also not yet clear, but it is clear that you should not wait for really cheap mobile phones based on Snapdragon 660, with the exception of Xiaomi.

And here Qualcomm makes an unexpected "feint" and releases the Snapdragon 636 ...

Everything is like in a cool processor, but in small doses

Unlike all modern mid-range processors, the Snapdragon 636 was not “inflated” from a cheap model, but “cut off” from an expensive one. Qualcomm took the same Snapdragon 660 as the basis and lowered the indicators a little bit in each of the characteristics.

The same 8 fast Kryo 260 cores, of which 4 cores are powerful Cortex-A73 redesigned in a new way, and 4 more are similarly customized economical Cortex-A53s. Only now the maximum frequency of the four fast cores can be a maximum of 1.8 GHz. That is, the processor part has lost about 20% of the performance and will give out approximately 4600-4700 points in the multi-thread of the Geekbench benchmark. “It’s not enough,” you say? But this is 55-60% faster than the Snapdragon 625 in your Xiaomi Redmi Note 4 or ASUS ZenFone 3 can produce, and 40% faster than in the overclocked to the limit Snapdragon 630 with the old type of cores. The RAM, however, was "cut off" from 1866 MHz to 1333 MHz, but it does not affect the performance in any way noticeable, to grieve about this.

40% CPU boost over the 8x Cortex-A53 at 2.2 GHz

Qualcomm representatives speak allegorically about the Adreno 509 graphics accelerator - no data on the clock frequency or the number of processing units. Nobody would put a finger on separate graphics in an economical processor, but admit that the fast Adreno 512 was artificially slowed down and worsened (no support for Quad HD-displays, only Full HD + in elongated and regular screens), this would be a marketing failure. Therefore, they simply nod towards the Snapdragon 630 and say that the graphics are 10% faster.


Chipset	Snapdragon 636 (SD636)	Snapdragon 660 (SD660)
Year of issue	2017 year	2017 year
CPU	8 cores (8x Kryo 260, up to 1.8 GHz)	8 cores (4x Kryo 260 2.2 GHz + 4x Kryo 260 1.84 GHz)
Video accelerator	Adreno 509	Adreno 512
RAM	LPDDR4, 1333 MHz	LPDDR4 1866 MHz
Wifi	802.11ac Wave 2, up to 433 Mbps	802.11ac Wave 2, up to 867 Mbps
Bluetooth	5.0	5.0
Maximum performance in LTE networks (download / download)	600/150 Mbps	600/150 Mbps
Process technology	14 nm FinFET	14 nm FinFET

And this is embarrassing. Because, if we have before us an Adreno 512 slowed down by 20-25%, then it cannot be only 10% faster than an old, repeatedly modified video accelerator from old chips (Snapdragon 625 and others like them). Either Qualcomm unearthed the grave of Snapdragon 652, took out Adreno 510 from there and slowed it down, or we are faced with another feat in overclocking the long-obsolete Adreno 506 (from Snapdragon 625) “I can’t do it”. In any case, the graphics in Snapdragon 636 by today's standards pulls the game “back to back”, without a margin for a bright future, even for Full HD-resolution.

One of the most powerful processors for smartphones has finally come out. Its digital designation has been known for a long time - 845, but the list of smartphones that work on this chip is still incomplete. However, we can tell you something interesting right now.

Samsung Galaxy S9 64Gb

One of the most important novelties of the season was the latest Samsung Galaxy S9, which, however, was not revolutionary, which can not be said about its predecessor Galaxy S8. The case design has been updated, but in general the brand is guessed instantly.

The smartphone has become more powerful, it has a better camera, additional functionality has appeared.

The Galaxy S9 ships with the Exynos 9810 proprietary processor in most markets, but in some countries it can be found on the Qualcomm Snapdragon 845 processor. This version is not available on the Russian market (at the time of writing), so be careful.

Samsung Galaxy S9 + 64 Gb

The same S9, only with a larger display to 6.2 inches (Galaxy S9 screen size is 5.8 inches). Another difference is a dual rear camera, not a single one.

As in the previous case, the Qualcomm Snapdragon 845 processor version is not officially delivered to us.

Asus ZenFone 5z

And here is the new flagship from ASUS - 5z. There is also a version of Asus ZenFone 5, but it is built on the basis of a less powerful processor - Snapdragon 636, and the ZenFone 5z uses Snapdragon 845.

As you can see, the smartphone has a frameless body, but the company decided to follow the path of Apple and used a small cutout at the top of the screen, where the sensors and camera are located. It resembles the iPhone X. There is also a similarity in the back - the camera module is located vertically.

But the amount of RAM is as much as 8 GB.

Sony Xperia XZ2

The flagship Sony, as expected, received a Qualcomm Snapdragon 845. The memory capacity is 4 GB of RAM and 64 GB of internal.

The case design is frameless, and therefore a 5.7-inch display is used. Dimensions are small. There was a wireless charge, which is good news.

Most striking is the completely updated design of the case.

Sony Xperia XZ2 Compact

A completely new version of Compact. And if the diagonal of the smartphone of the previous generation was 4.6 inches, now it is 5 inches. But the dimensions are still small by reducing the scope.

As with the Xperia XZ2, the design is completely new.

The manufacturer in both models abandoned the mini-jack - a USB Type-C port is used for headphones.
