2015
This year, the company lost most of its advantage over competitors, as the top-end 810 model turned out to be unsuccessful, and therefore companies collaborating with Qualcomm had to use the weaker 808 model or develop cooling systems for the 810. New chipsets of the 6xx and 4xx series are not presented were, and customers had to be content with outdated (compared to similar products from competitors) last year’s models.
The company's revenue decreased by 7% compared to the previous year and amounted to $23.6 billion.
Problems of the 810 model
At the end of 2014, Qualcomm did not have a top-end eight-core platform of its own design, as a result of which it decided to use ARM cores at high frequencies. In terms of power, the processor was comparable to Samsung's Exynos 7420, but due to its larger (20 nm vs. 14 nm for Samsung) process technology, the 810 generated more heat and overheated quickly. When overheating, in order to avoid processor failure, frequencies were forcibly reduced, and, as a result, performance dropped. Due to the reasons described above, sales of the 810 were lower than its predecessors, causing the manufacturer's profits to decrease.
810
Considered a failure for Qualcomm due to its tendency to overheat. It has four Cortex-A53 cores and the same number of Cortex-A57 cores, operating at frequencies up to 2.0 GHz. ARMv8-A, 20 nm. “Graphics” - Adreno 430.
808
It was released by the manufacturer as a less powerful, but much more stable alternative to the 810 model. It is the first six-core system on a chip in the world. Video processor - Adreno 418.
210
A follower of the 200 model, created using a 28-nanometer process technology on ARMv7 architecture. Four Cortex-A7 cores are used, operating at frequencies up to 1100 MHz. Graphics subsystem - Adreno 304.
2016
Successful models of all price categories have been released that do not suffer from overheating.
820 and 821
Flagship Snapdragon solutions created using 14 nm process technology, which eliminates the tendency to overheat inherent in last year's solutions. Architecture - ARMv8-A. They have 4 Kryo cores of the manufacturer’s own design and a clock frequency of up to 2.35 GHz for 820 and up to 2.45 GHz for 821. The Adreno 530 graphics coprocessor is used.
Xiaomi has become famous all over the world as manufacturers who install top-end hardware into their devices. It is due to this, as well as the low price tag, that their smartphones are incredibly popular. Most even inexpensive devices take good photographs and have high-quality displays. But the main thing is that the most powerful Qualcomm Snapdragon processors are responsible for their operation, providing high performance.
The company plans to release dozens of smartphone models in 2019. Therefore, we have prepared an article about the chipsets that will be used in them. This material will help you avoid falling for the tricks of marketers and accurately choose a powerful device or gaming phone.
The first part of the article will be informative for those who want to understand the topic, and not just get an answer as to which chip works faster. We will analyze the features of new Qualcomm cores and processors. In the second, we will sum up the results and clearly explain what solutions to pay attention to, and we will also display a rating of current processors based on the power of cores and graphics chips.
Smartphone performance reaches new levels
This year we will see a scattering of new Qualcomm chipsets in devices from the Chinese brand. Some of them hardly need any introduction, such as the Snapdragon 855 (SDM8150). Everyone already knows that this is a flagship solution with the highest level of performance. But with mid- and budget-class processors (the most popular from Xiaomi), everything is not so clear.
There are many pitfalls that you can easily stumble over when choosing a powerful device, and it will perform, for example, in games not as well as you expected.
Below we will try to talk as succinctly as possible, but clearly about the features of processors in Xiaomi. After all, the American chipmaker Qualcomm has begun to mass produce inexpensive SoCs based on new, energy-efficient, but productive cores.
By the way, the sameSnapdragon 855 is not a processor, butSoC (system on a chip, single chip). That is, the board on which the processor subsystem is installed (for example,Kryo 360), graphic and many others.
Features of nuclear labeling
Almost any new generation processor is very good. By new generation we mean chips built on the new microarchitecture of ARM cores. Cortex-A55 are small, power-efficient cores, while A75 and A76 are large, high-performance cores. This is a kernel standard released by ARM Corporation. These developments are used by Qualcomm, Samsung, Apple, Huawei and MediaTek when creating their cores and pay a licensing fee to ARM.
In short, thenA55,A75 andA76 is much better than their predecessors in the faceA53,A72 andA73. Especially stands outA76. It is 35% more powerful thanA75.
They are more productive, energy efficient and support new technologies. Without going into numbers, we’ll just say with confidence: if it’s possible to get a phone with a processor with updated cores, it’s better to do so. It will be relevant longer, and you will get more pleasure from using it. The improvements in smooth operation, reduction in heating and battery consumption will be very noticeable.
Custom kernelsQualcomm basedCortex are calledKryo.
They have markings that it is advisable to understand so as not to be fooled by the speculations of marketers trying to confuse us.
The following CPUs are built on A55 (Kryo XXX Silver) + A75 (Kryo XXX Gold) cores:
- Kryo 360 (Snapdragon 670, 710, 712);
- Kryo 385 (Snapdragon 845).
The following CPUs are built on A55 (Kryo XXX Silver) + A76 (Kryo XXX Gold) cores:
- Kryo 460 (Snapdragon 675);
- Kryo 360 (Snapdragon 855).
Now, by looking at the characteristics of several smartphones, you can understand which of them is more powerful in terms of CPU.
Don't forget that the new flagshipSoC fromQualcomm have a 4 + 4 or 4 + 3 + 1 layout, and mid-segment ones have 6 + 2. The first number is the number of small cores, the second - large ones.
Rating of Qualcomm processors specifically based on processor power
CPU performance is important for system performance and less so for gaming. The better the cores, the faster applications open, browser tabs, conversions, etc. If these parameters are important to you, choose a smartphone based on SoC in accordance with the top list below.
#1 - Snapdragon 855
The flagship and most powerful chip, the appearance of which is only expected in Xiaomi gadgets. It is known that this is the ultimate solution with a powerful video accelerator and CPU. Its power is comparable to the latest Apple chips and will last for 3-4 years.
Interestingly, it is built according to the 4 + 3 + 1 scheme. That is, there is an “alpha core” for executing single-threaded processes and achieving high performance in benchmarks.
#2 - Snapdragon 845
Last year's flagship based on A55 and A75 cores. Extremely balanced chip. Energy efficient and still incredibly relevant due to fast graphics and four large cores that provide excellent performance.
#3 - Snapdragon 835
This chipset also turned out to be successful. Although it is based on the cores of the previous generation, they have a high frequency, and the graphic capabilities of this single-chip system are still superior to all younger and even newer models.
#4 - Snapdragon 675
"Golden Boy" episode six hundred. In terms of processor, it is more productive than the SDM670 (Snapdragon 670) and even 710, 712, which are a class higher. All this is thanks to the Cortex-A76 cores. It has the same computing power per thread as the SDM845. There are fewer large cores, so peak performance is lower. But it will still provide excellent smoothness and speed.
For us, as users, the most pleasant thing is that 675 is an affordable chipset, and it will be responsible for the operation of the future “people's” smartphone Xiaomi Redmi Note 7 Pro.
#5 - Snapdragon 712
An overclocked version of the 710, which relies on a graphics accelerator. In this parameter, it has “galloped away” far from the 675 and is slightly ahead of its predecessor. But it has a large cluster on the A75, so it will perform single-threaded tasks worse than the chip in fourth place.
#6 - Snapdragon 710
The same 712, as you already understood, but with lower frequencies. It “blew up” the market for mid-budget smartphones, as it delivered speeds in everyday tasks at the level of the Snapdragon 835, the flagship SoC of 2017. At the same time, it had powerful graphics, did not overheat and ran all games at maximum speed.
#7 - Snapdragon 670
It is weaker in CPU, but ahead of the 675 in graphics. A very good chipset. Its lag from fourth and fifth places is insignificant due to weak design differences.
#8 - Snapdragon 660
“Old Man”, which has been on the market for four years now. An extremely high-quality and balanced processor that has not lost its relevance for a long time. Its video accelerator is only slightly weaker than that of the 675, but the A53 and A73 cores do not produce such a smooth picture and performance per thread. There is also strong throttling (frequency drop due to overheating), and energy efficiency leaves much to be desired.
#9 - Snapdragon 636
This is a stripped down 660. It has an acceptable level of performance on the CPU, but the graphics capabilities are almost 30% inferior to its “big brother”. But there is no throttling, and it slowly drains the battery.
Rating of Qualcomm Snapdragon processors by video accelerator power
In the previous paragraph, we indicated the distinctive features of each of the chips, so in this one you will find simply the TOP of the most productive smartphones in games.

| 9 | SDM636 | 1350 | 4900 | 115 000 | 22 000 |
As you can see, the 675th “dragon” sank greatly here. As conceived by Qualcomm, it has excellent cores, but is inferior to its peers in terms of graphics. Not the most universal solution. Ideal for those who do not need to play at maximum settings, but just need a very fast device.
Pay attention to how far the flagships have moved away from mid-budget phones in terms of graphics power. That's why we say they'll last four years or more for gaming. After all, stagnation in the development of chips should soon begin, as happened in processors for PCs.

Conclusion
This information is enough for you to take a look at several different phones (not just from Xiaomi) and evaluate their potential level of performance. This is especially useful for mobile gaming enthusiasts and users who want the most powerful device possible, but are confused by the variety of modern single-chip systems.
In the future, we will publish articles about the most productive Xiaomi smartphones. In addition, there will be a comparison of the processors used in the devices of this company with the chipsets of competitors.
Perhaps in 2019, Snapdragon processors are the most popular in the mobile device market: even companies that produce proprietary chipsets (Samsung and Huawei) sometimes install Qualcomm developments in their devices. Now there are a great variety of Snapdragon processor models on the market, among which it is easy to get lost. Rule “the higher the numerical index of the chipset, the cooler it is” does work when choosing the best chipset from Qualcomm, but not always. In addition, sometimes a more expensive model is practically no different from its “younger brother,” but devices based on it are much more expensive. In this article we will name the best representatives of each of the Snapdragon model series, describe the features of all series and the chipsets themselves.
What really matters in processors
In this article, we will not compare absolutely all technical characteristics of processors, since most of them are not important when choosing mobile devices: for example, information about the maximum camera resolution supported by the chipset or the ability to work with LPDDR4X memory will not help a person in any way when choosing a gadget (since the buyer purchases a smartphone or tablet with a camera and memory already installed, and not a computer where, if desired, any components can be replaced - even if the processor installed in the mobile device supports the best components, this is absolutely unimportant).Characteristics of processors that you should pay attention to when purchasing a device:
- Technical process: chipset manufacturing technology, characterized by the resolution of the equipment used in the production of processors. Simply put, the fewer nanometers (nm), the better: cores created using the 7 nm process are more economical and more productive than their 10 nm counterparts, all other characteristics being equal.
- Core clock speed: shows the number of operations performed per second and is measured in Hertz (Hz). The higher it is, the more productive the processor cores are.
- Number of Cores: the more cores, the less the chipset is overloaded - all thanks to the better ability to distribute processes between several cores.
- Number and composition of clusters: To increase the energy efficiency of processors, cores with the same performance are installed in separate clusters. This allows you to separate productive cores from economical ones, so that resource-intensive tasks are performed only by “powerful” cores, and simple tasks are performed exclusively by low-performance cores. Almost all processors are built in a dual-cluster format, but in the Snapdragon 855, Qualcomm has resorted to technology with three clusters: in addition to productive and economical cores, the chipset contains medium-power cores. In theory, the more clusters, the more economical the processor.
- Graphics accelerator: This is an integrated video card in a smartphone, installed on the same board with the processor. Unfortunately, Qualcomm rarely shares the features of its Adreno series video accelerators, so the technical characteristics of some of them are unknown. What is clear is that the higher the numerical index of the GPU, the better the hardware.
- Digital Signal Processor (DSP): is a chipset that processes signals from various sensors of mobile devices in real time. It is much “weaker” than the central processor, but its performance is sufficient to perform its function. If DSP were not used, the sensor readings would be processed by the main processor, spending too much energy on non-resource-intensive tasks. Qualcomm doesn't reveal the specs of its Hexagon series DSPs, but we can safely assume that the higher the number, the better.
Snapdragon 8xx - flagship models
Qualcomm demonstrates all its developments over the past year in its flagship processors. That is why the models in this series are sometimes significantly different from their predecessors. However, this does not always happen. For example, the Snapdragon 855 is significantly superior to the 845 model, since the new product uses a three-cluster format, is created using an advanced technological process and has an improved graphics accelerator and digital signal processor.
But the Snapdragon 845 did not receive fundamental changes compared to the Snapdragon 835 in terms of CPU performance, but its graphics accelerator was significantly improved (at least according to official statements).
We do not recommend considering smartphones based on Snapdragon 821 and 820 in 2019, since these chipsets are already quite outdated: the old process technology and four cores are not suitable for modern games and programs. In addition, for the price of devices with these processors, it is better to purchase modern sub-flagship smartphones or middle-class gadgets, which we will discuss below.
Popular smartphones with Snapdragon 855 processor:
- Xiaomi Mi 9 / Mi 9 TE
- Samsung Galaxy S10 / S10+ / S10e
- Xiaomi Mi 8 / Mi 8 EE / Mi 8 Pro
- Xiaomi Pocophone F1
- Xiaomi Mi MIX 3

- OnePlus 6/6T
- Google Pixel 3/3 XL
- Nokia 9 PureView
- Samsung Galaxy S8/S8+
- Samsung Galaxy Note 8
- OnePlus 5/5T
- Google Pixel 2/2 XL
Snapdragon 7xx - sub-flagship models
Processors in this series are designed for sub-flagship smartphones, which require decent performance, but do not require various features of flagship models (such as support for ultra-high-resolution screens, sophisticated cameras, and the like).
The Snapdragon 730 differs from the version with the “G” prefix only in that the frequency of the latter’s video accelerator is slightly overclocked, making its graphics performance 15% higher. However, in practice, the difference between these chipsets is incredibly difficult to notice, so you can safely choose devices with the Snapdragon 730 (without overpaying for gadgets with the G version of the chipset).
The Snapdragon 712 and 710 processors are inferior to older models, and noticeably (judging by reviews and benchmarks). If you choose between gadgets based on these chipsets, then it’s certainly not worth paying extra money for the 0.1 GHz increased clock frequency of the two productive cores in the 712th “dragon”.

Snapdragon 6xx series processors are designed for mid-range devices. Previously, these models were significantly inferior to their “big brothers”, but the Snapdragon 675, 670 and 665 released over the past two years have changed everything: these chipsets are not so much inferior in performance to models from the Snapdragon 7xx line. These three are quite similar in characteristics, and the 670 is even slightly ahead of the 675 in graphics and power consumption. As a result, when choosing a mobile device, you can safely consider gadgets on these three processors to be almost equal in performance.
Snapdragon 660 and 636 can already be called oldies, but manufacturers continue to release smartphones and tablets with these chipsets, since they still cope well with games and programs (even if not with the most demanding ones). The choice between these processors is simple: the 660 is an order of magnitude better than the 636 (but also more power hungry).

Snapdragon 4xx - entry level
The Snapdragon 4xx line is aimed at budget devices, so you shouldn’t expect any miracles from processors in this series. Devices based on Snapdragon 450 and 439 have approximately the same performance, but the latter is still preferable. Gadgets powered by Snapdragon 429 should only be considered if your budget does not allow you to purchase a smartphone with the chipsets described above. But devices based on Snapdragon 435 should be completely avoided - it is outdated in every sense.
Popular smartphones with Snapdragon 450 processor:

Snapdragon 2xx - as cheap as possible
The Snapdragon 2xx series is designed for ultra-budget devices. These chipsets are needed to process basic functions, so they are installed only in the cheapest smartphones designed to replace push-button dialers. In addition, manufacturers no longer produce devices based on these processors - the latest smartphone with a chipset from this line is Nokia 2 (2017).
If you choose a “dialer” for yourself, then you can take a gadget with any of the Snapdragon 2xx series processors, since they are all approximately equal (except that you should give preference to models with 4 cores). Devices based on these chipsets should not be purchased for other purposes, since in 2019 their use will turn into real torture.

Qualcomm is a well-known developer of chipsets for mobile devices. Its arsenal includes processors for smartphones of all price categories. In the upper price niche, the company is the leading supplier of SoCs for phones; in the middle, it also has an impressive market share, and only in the budget category are Taiwanese competitors represented by MediaTek.
Qualcomm chipsets are usually equipped with a special Hexagon DSP (digital signal processor). It is responsible for processing voice, sound, and sensor readings in order to reduce the load on the main cores and optimize power consumption.
Our article will tell you what current processors are in the Qualcomm lineup at the beginning of 2017. The material does not consider discontinued and rare products, like the Snapdragon S4, but is dedicated only to those found in smartphones that are being sold or are about to be sold.
Chipsets for very inexpensive smartphones (under $100) are clearly not the company’s strong point. However, Qualcomm has plenty of budget chips in its arsenal. Traditionally, they come out under model numbers 200 and 400 series.
Snapdragon 200
An old budget processor, available in 4 versions. All of them have 4 cores made using the 28 nm process (the earlier ones were made using the 45 nm process), but differ in the type of these cores, as well as graphics. The 2 models with 1.4 GHz have Cortex A5 microarchitecture (32-bit) and Adreno 203 graphics, clocked at 300 MHz and with a performance of 9 GFLOPS (billions of floating point calculations per second). Models with a frequency of 1.2 GHz are equipped with Cortex A7 cores (also 32 bits) and Adreno 302 graphics (400 MHz, 12 GFLOPS).
All chipsets in the series are equipped with a single-channel LPDDR2 controller (300 MHz). Displays with resolutions up to 1280x720 pixels are supported. This chipset does not have an ISP, so the camera resolution depends on what the external image processor supports (Qualcomm usually uses an ISP made by Texas Instruments). The modem works with Wi-Fi 2.4 GHz networks, GSM, CDMA and HSPA operators, depending on the version (no LTE).
The maximum camera resolution that the chipset can support is 8 megapixels.
Snapdragon 210
This is a development of the previous model; the processor is produced according to 28 nm standards. It has 4 Cortex A7 1.1 GHz cores, Adreno 304 graphics. Its frequency is 400 MHz, performance is 21 GFLOPS.
The memory controller supports LPDDR3 and LPDDR2 chips up to 533 MHz. The display controller is designed for resolutions up to 1280x720; there is no image processor in the chip. The modem is designed for Wi-Fi networks 2.4 GHz, GSM, HSPA, CDMA and LTE Cat. 4.
The maximum camera resolution supported by the chipset is 8 megapixels. There is even support for second generation fast charging technology. This is an old technology that, on paper, allows you to charge smartphones in less than three hours, but in practice, the chipset in question is unlikely to be found in a smartphone with second-generation fast charging from Qualcomm.
Snapdragon 410
A processor for smartphones of a higher class than the 200th model. Based on 64-bit architecture, but produced according to the same 28 nm standards. Has 4 Cortex A53 cores up to 1.4 GHz. Graphics processing is handled by the Adreno 306 GPU, with a frequency of 400 MHz and a performance of 21 GFLOPS.
The chipset is equipped with a single-channel LPDDR2/3 (533 MHz) RAM controller. The display resolution can reach FullHD 1920×1080 pixels. There is no built-in ISP; cameras up to 13 MP are usually supported. The radio module supports Wi-Fi 2.4 GHz, cellular networks up to LTE Cat. 4.
The maximum supported camera resolution is 13.5 MP. Fast charging technology may be of the second generation.
Snapdragon 425/427
These Qualcomm processors belong to the budget category and are a continuation of the 415 model. They are also manufactured at 28 nm and have 4 Cortex A53 cores. They operate at a frequency of 1.4 GHz, Adreno 308 graphics are installed on board. The GPU frequency is unknown for certain (the only smartphone with this SoC, Xiaomi Redmi 4A, will not be widely sold), the approximate performance is about 30 GFLOPS.
Both processors are designed for LPDDR3 memory (667 GHz). Display resolution – HD 720. The differences between Qualcomm Snapdragon 425 and 427 are in the networks: both support Wi-Fi of two standards and all 2nd and 3rd generation networks. But the 425 has LTE Cat 4, and the 427 has LTE Cat 7.
The 425th model supports its own second-generation fast charging technology, the 427th model supports 3rd generation fast charging. The camera can be a maximum of 16 megapixels for both.
Snapdragon 430/435
These Qualcomm processors are the most advanced in the budget segment. Both are manufactured using a 28 nm process technology and have 8 Cortex A53 1.4 GHz cores. Graphics processing is handled by the latest generation Adreno 505 accelerator. The clock frequency of the video processor is 450 MHz, and the theoretical performance is up to 49 GFLOPS.
The memory controller is designed for LPDDR3 800 chips. The display resolution can be either HD or FullHD. Both chipsets support almost all current networks, but the 430 model has an LTE Cat 4 modem, and the 435 has a Cat 7 modem.
Qualcomm third generation fast charging is supported. The chipsets can process camera images at a resolution of 21 megapixels.
Mid-range Qualcomm Snapdragon chipsets
Among mid-range chips, Qualcomm has good SoCs for both mid-budget and almost flagship devices. They are usually in the 600 series, but there is one exception.
