Date of last update: 4 January 2017 at 18 h 57 min

Qualcomm lifts the veil on its 835 Snapdragon at CES 2017. We had the chance to discover the SoC in preview and you summarize here the key points to remember from the new Qualcomm processor that will fit a lot of high-end in 2017 smartphones.

all that there is to know about the 835 Snapdragon from Qualcomm

as every year, Qualcomm improves its formula with a SoC always more powerful that consumes less power to push the limits of our mobile products. The new model is no exception to this rule. This year, Qualcomm and Samsung are partners for the production of the Snapdragon 835 , offering him a 10 nm FinFET engraving.

The founder does not merely to improve the 821 Snapdragon in every way, the company is also preparing the future by anticipating the uses that are developing more and more as the virtual and augmented reality or still the connection permanent services in the cloud while maintaining a high level of security. Specifically, here are the technical details of the SoC.

Main technical features of the Snapdragon 835

  • CPU : 8 cores Qualcomm Kryo 280 (4 x 2.45 GHz + 4 x 1.9 GHz)

  • GPU : Adreno 540 (Support OpenGL ES 3.2, OpenCL 2.0, Vulkan and DirectX12)

  • Camera ISP (digital imaging processor): Qualcomm Spectra 180

  • DSP (digital signal processor) : Qualcomm Hexagon 682

  • Modem Snapdragon X 16 : LTE category 16 (1 Gb/s download/150 Mb/s upload), WiFi 2 × 2 MU-MIMO 802.11ac (optional 802.11ad), Bluetooth 5.0

  • Audio : processor Qualcomm Aqstic Audio (support 32 bit/384 kHz)

  • security platform : Qualcomm Haven (biometrics and certifications)

  • burning : 10 nm FinFET

  • Support Quick Charge 4.0

more power thanks to the processor Kryo [280

burned in 10 nanometers, Kryo 280 processor is based on ARM Cortex technology with architecture 8 cores. Four of them are dedicated to performance with a maximum frequency of 2.45 GHz and 2MB L2 cache. The other four are clocked at 1.9 GHz with 1 MB L2 cache for energy consumption more controlled.

Qualcomm ensures that 80% of the time, will be the most fuel-efficient four cores to be used , four others will be sought for specific tasks requiring more power as the launch of an application, web browsing or virtual reality. If the gain in performance compared to the Snapdragon 821 is real, Qualcomm did not insist on this point. We will judge this on room during our first tests of smartphones equipped of the NCS.

Better battery life: 25% more efficient in energy

the 835 Snapdragon is obviously the most economical energy processor ever made by the founder. Smaller in size compared to the S821 by 35 percent, it is also 25 percent more economical in energy. Qualcomm promises 2.5 h battery and more on a day of mixed use.

Qualcomm says its new SoC is able to hold 1 day on appeal, 5 days in music playback, 11: 00 video playback 4 local K, 7 h 4K video playback streaming, 3 h in video capture 4K and 2 hours of play in VR. These figures are of course given indicative and depend on the smartphone in which the 835 will be integrated.

Fast charging improves with the introduction of Quick Charge 4.0 , 20% faster than version 3.0 technology. The promise is simple: 5 hours talk time to 5 minutes of charging.

the support of USB Type-C reversible as standard USB Power Delivery (UPD) can deliver a theoretical power up to 100 Watts with a minimum of 5 v voltage and a maximum voltage of 20V, for intensity of electricity up to 5A.

Architecture of SoC based on the CPU, GPU and DSP (digital signal processor) combined with the software optimizations also participate in the performance gain and energy efficiency of the Qualcomm chip.

On augmented reality and virtual reality


the VR and AR are of course at the heart of the concerns of Qualcomm. The 835 Snapdragon is so logically built for perfectly work with the Google Daydream VR platform. The tracking of movement, combined with the graphics and sound improvements (3D audio) of the SoC, promises a full immersion in the virtual and augmented reality.

The 540 Adreno GPU offers a graphic rendering 3D 25% higher than that proposed by the Adreno 530 S821 and S820. The color rendition is also improved with support for 10-bit display and the 4K in HDR10. Qualcomm intends do not leave overwhelmed by competition in this area.

Photo capture becomes smarter

thanks to its new processor for processing digital image (ISP), the Spectra 180, Qualcomm accompanies the photo sensor in taking pictures by allowing a smoother zoom, autofocus faster and greater wealth of capture of colors thanks to HDR, as well as photo and video.

The SoC is also ready for all the cameras that will equip our smartphones in 2017 with a support of simple up to 32 megapixel sensor, or two 16 Megapixel sensors. Side video, it will be possible to register in 4K@60 FPS and 4K@30FPS, with the support of the formats H.264 and H.265.

Connectivity: 4 g LTE up to 1 Gb/s

the modem Snapdragon X 16 presented by Qualcomm joined the S835 promises connectivity of first place with a LTE connection that can reach up to 1 Gbps. WiFi is not left with the integration of the 2 × 2 802.11ac and even the 802.11ad to offer the Wi – Fi multigigabit. 5.0 Bluetooth support is also of the part.

the goal of Qualcomm is here to offer a technology ready for the future today. The founder anticipates the progression of the mobile network in the months and years to come while thinking about the uses of tomorrow. Ultimately the company think that we will make more of a difference between the wired and wireless in terms of performance, with instant connection to all services (download, playback of multimedia content, storage in the cloud, etc.).

Secure personal data

our smartphone is now the heart of our personal data, but is also increasingly means of payment used. Our mobile security is therefore a major issue on which Qualcomm wants to reassure users and businesses. It’s Heaven security platform that takes care of this component related to security.

Recognition of fingerprint, Iris, face, as a way to protect its data. With its Snapdragon 835 authentications at several levels are performed whether at the level of hardware and software for secure access to sensitive data.

Machine learning at all levels

the term “Machine Learning” you are surely not unknown, many manufacturers and brands are beginning to put forward, though it has existed for years. We could translate it by automatic learning of artificial intelligences through statistics, or how the machine learn to improve.

in analysing the way in which you use your smartphone, the latter will be able to learn and evolve to improve some process by automating them. This will allow both a more intelligent capture of the camera through an analysis of the scene, or even the prioritization of certain tasks by the processor that can anticipate your needs based on your habits.

That’s what we can tell you for now on the new Snapdragon 835 of Qualcomm that looks promising. We look forward to be able to test it more in detail in the 2017 smartphones that will use it. If you have any questions, feel free to ask in the comments.
