On the eve of the CES in Las Vegas, Qualcomm details Snapdragon 835 chipset officially announced. The new chipset will be in the new top smartphones, but also in virtual and augmented reality headsets.
Qualcomm Snapdragon 835
That Qualcomm are the new top chipset at the CES would launch, it was already no surprise. In fact, the chipset was mid-november already announced, but many details were still missing. What we already knew is perhaps the most important information: the chipset is made by Samsung.

That Qualcomm, Samsung have chosen is not so strange: that the company is currently in the forefront when it comes to the manufacture of efficient chipsets. Use is made of a 10nm process, which means that the connections within the chips to be incredibly small. The previous generation of chips had 14nm connections, and by the reduction in the size is the chipset itself also became much smaller than before: the Snapdragon 835 is 35% smaller than the Snapdragon 820.
Because the chipset is so much lower, according to Qualcomm, more space for a larger battery. In addition, the company that the chipset is 25% more energy efficient than the Snapdragon 820, which in turn for a better battery life would need to care.
New processor and graphics chip
Processors in mobile chipsets are almost exclusively based on the ARM architecture. This British company offers various license forms for the use of their processor architecture. So is it possible to have the processor cores of ARM one-on-one to take over, or is it possible to get a license (a version of) the underlying architecture. At the hitteproblemen troubled Snapdragon 810 chipset chose Qualcomm for the first license, and the company opted for a private processordesign to use for the Snapdragon 820. With the Snapdragon 835 is selected for a new type of license, that somewhere in between is: the cores of the Snapdragon 835 are based on ARM cores that have been modified by Qualcomm.
The processor of the Snapdragon 835 hot Kryo 280 and is an octa-core setup which makes use of a so-called big.LITTLE principle. Use is made of two quad-core processorclusters, one of which is intended for processing of heavy tasks and the other on a more energy-efficient way to lighter tasks are processed.
The graphics chip in the Snapdragon 835 is the Adreno 540. This chip is an improved version of the Snapdragon 820 to find the Adreno 530, and would be 25% faster when processing 3D images. That seems partly to be due to a higher clock speed, but will also have to deal with other improvements in the architecture.
Better cameraverwerking
In the Google Pixel devices we have seen that the processing of the images taken with smart phone camera’s shot, very important for the image quality. Qualcomm indicates that in the Snapdragon 835, the processing performance is improved, which among other noise faster and better can be removed.
The Snapdragon 835 has a Spectra 180-chip support for hybrid auto focus, which is the best form of focus can be chosen on the basis of the lighting conditions. There may also be zig-zag-HDR, which direct a preview can be given of HDR photos or videos in HDR can be included. The verwerkingschip of the new chipset, the Hexagon 682 DSP, provides extensive processing capabilities, which can for instance be used to direct the focus on the faces or by (beauty)filters to apply.
what’s Interesting is that the chipset provides support for two cameras with a maximum resolution of 16 megapixel, or a single camera with a resolution of 32MP. In addition, use can be made of the Qualcomm Clear Sight technique to the images from two cameras to combine. Then it can go to two of the same cameras or one camera with a wide angle lens and a normal camera. To the manufacturers are easier to create certain camera set-ups to use in their devices, Qualcomm camera modules offering.
Virtual and augmented reality
One of the priorities of the Snapdragon 835, virtual and augmented reality. By improvements in the audio chip could, among other things, the processing of 3D sound is a lot better and is also working on reducing delay between the moving of the head and the appearance of new images on the screen of a virtual reality headset.
The first Snapdragon 835 device that is announced, is a virtual reality headset, created by the American ODG.
Devices with Snapdragon 835
There are officially still no smartphones with Snapdragon 835 chipset announced, but that will be this week yet to happen: we expect that ASUS new ZenFone announces that runs on this new chipset. In addition, it will likely be the new flagships of Sony, LG and HTC on this chipset run, as well as the Samsung Galaxy S8 in different countries.
