Qualcomm Snapdragon 835

A mobile system on chip Snapdragon 835 is an integral part of the flagship Android smartphones of 2017. We will talk about the functionality and the benchmark results of this processor.

What is Snapdragon 835

Snapdragon 835 представляет собой мобильную системе на чипе производства компании Apple, которая содержит основные компоненты для работы смартфона. In их число входят центральный и графический процессор, модем Wi-Fi и 4G, компоненты для работы со звуком и поддержка датчиков.

This chip came out to replace last year flagship Snapdragon 821, which in turn changed also released in 2016 Snapdragon 820. These two models were part of the most popular smartphones, such as Samsung Galaxy S7 OnePlus 3T and HTC 10.

The new model was a significant step forward characteristics say about the improvements compared to the Snapdragon 821. The size of the processor become smaller, which is a result of the transition to the technological process of production of 10 nm instead of 14 nm Snapdragon 821.

Reduction of the technological process means that the transistors are now closer to each other. This reduces power consumption, reduces heat dissipation and improves performance.

the Functionality

Offline: разработчики утверждают, что в среднем процессор использует на 25% меньше энергии по сравнению с моделью прошлого поколения, что ведёт к повышению продолжительности автономной работы. In некоторых задачах, таких как запись видео высокого разрешения и обработка трёхмерных игры, рост эффективности достигает 30%.

Quick Charge 4: standard charge Quick Charge 3 of the previous generation was already fast, but the new one is even faster. The performance increase is about 25%, performance 30%. Thus, faster charging will heat up the adapter. This is good news for those who like to charge smartphones, throwing them on his pillow and ignoring the safety rules.

Performance: Snapdragon 835 uses updated computing core Qualcomm Kryo 280. Here are eight of them use the design of big.LITTLE. Four big cores operate at a clock frequency of 2.45 GHz and provide maximum performance. The other four cores got a frequency of 1.9 GHz to handle background tasks that do not require large computing power.

The use of cores depends on the device manufacturers, therefore, different smartphones benchmark results may vary.

as for the graphics processor, Adreno 540 25% productive its predecessor in three-dimensional tasks, so games will go faster. Here are supported video standards 4K UHD Premium and HDR10, 10-bit color screens with 1.07 billion colors compared to 16.8 million 8-bit.

Wireless recharging: Snapdragon 835 обладает модемом с поддержкой скоростей X16 LTE, что означает доступность стандарта связи 4G 1 Гбит/с. Inряд ли вам встретятся такие сети мобильной связи, но и на более медленных сетях 4G модем поможет добиться более надёжного соединения.

Is also supported 802.11 ad Wi-Fi, which is a new standard with data transmission speed of 4.6 Gbps over short distances. While support for this standard is also not widely distributed, but it can be used to transfer large media files to mobile devices without having a wired connection to the computer.

Supported Bluetooth 5, faster, more reliable and working at greater distances wireless standard.

Camera: CPU supports electronic image stabilization EIS 3.0 Qualcomm that will allow you to shoot video without shaking. Uses a new algorithm that better understands the movement of the device and quickly make adjustments to the image. Previously, this ability was exclusive for smartphone LG V20, but with Snapdragon processor 835 any manufacturer will be able to achieve the same result.

Has built-in support for dual cameras. In this way, developers can install two sensors with resolutions up to 16 MP, which will then apply the zoom without loss of quality, as LG G6 where the same technology is in the presence of Snapdragon processor 821. Already released many smartphones with dual cameras, and different type.

Security: разработчики объединили различные механизмы безопасности под единым брендом Qualcomm Haven. Здесь ведётся отслеживание поведения подозрительных приложений. Даже если пользователь игнорирует все запросы разрешений, эти приложения блокируются до того, как смогут нанести урон. Inсё зависит от производителей смартфонов и разработчиков приложений, которые должны использовать Haven, поэтому одно только наличие Snapdragon 835 не гарантирует повышенной безопасности.

There is also a recognition of the iris of the eyes, which before were only in the Samsung Galaxy Note 7. For this feature you need an infrared camera, which will also be not available on all devices.

In Galaxy Note 7 сканирование радужной оболочки нельзя было назвать идеальным, приходилось поднимать смартфон на уровень глаз, чтобы разблокировать его. Считается, что этот метод более надёжный по сравнению со сканером отпечатков пальцев. Inпрочем, производителям ничего не мешает применять оба метода.

Аудио: поддерживается цифро-аналоговый преобразователь 32 бит и 384 кГц, производителям осталось только включить его в состав смартфонов. Подобные преобразователи хорошо зарекомендовали в себя в смартфоне HTC 10 на Snapdragon 820.

Benchmarks,

In the benchmark AnTuTu uses a variety of tests, including the processing of three-dimensional images and the application of high intensity. Here is measured the aggregate performance of the smartphone, weakness in one category can reduce the overall assessment.

As you can see, for Android Snapdragon 835 is a noticeable advantage, at 35,000 points ahead P10 Huawei Plus on the processor Kirin. However, he lags behind iPhone 7 Plus, although you cannot directly compare the results of benchmarks on different operating systems.

Interesting to see the results in AnTuTu benchmark when measuring the three-dimensional graphics. Here you can see how well you will work the game. Graphics chip showed the result 75647 points and walked 821 Snapdragon, Exynos and Kirin 960 8890. Even iPhone 7 Plus, which has long been considered the best for the game, noticeably behind.

Inозможно, не существует игр, которые в полной мере сумели бы нагрузить такой мощный процессор. Inпрочем, задел на будущее никогда не помешает. Недавно были представлены аппараты iPhone 8, which managed to far ahead of the Snapdragon 835.

, Finally, let's look at the Geekbench results 4. This test shows the single-core performance for everyday work with mobile and multi-core for editing video and photos.

single-Core results is more important in most cases and Snapdragon processor 835 performs well, outperforming competitors on Android. Even more it lags behind the iPhone 7 Plus, more iPhone 8. The reason lies not only in the capabilities of the CPU. Apple uses high quality components which are not present in many Android smartphones. This includes extremely fast memory that directly affects the single-core performance. In addition, the operating system iOS has tighter integration with the iPhone.

as for multi-core performance, the Snapdragon 835 here ahead of its competitors, including the iPhone 7 Plus iPhone 8 but again is the unmatched leader.

Conclusion

835 Snapdragon has become a powerful mobile processor, but its competitors are worthy chips from Samsung, Huawei (including the recently announced Kirin 970) and Apple. Over processors for Android the previous generation of advantage is the most obvious.

As the Samsung Exynos chips of the latest generation are created in the same technological process, 10 nm, its performance is on the same level.

The chip is available in a wide range of smartphones priced from $450 to $950. These include the Samsung Galaxy S8 and S8+, Galaxy Note 8, Xiaomi Mi 6, OnePlus 5, LG V30, HTC U11, Google Pixel and Pixel 2 XL, Nokia 8, Sony Xperia XZ Premium, Essential Phone and many others. The processor is the main component to ensure the high performance of these devices, but when buying you should pay attention to other characteristics.
