Introducing Snapdragon 690, Qualcomm’s first 5G mobile platform 6 series

News unit Qualcomm Company on Tuesday, June 16, 2020 ( June 27, 2019) from a new mobile platform called Snapdragon 690 unveiled that it is the first example of 6 series with support for 5G communication capability and according to the price category of phones Equipped with this platform, it is a big step towards wider access to the 5G network. Snapdragon 690 should be replaced

To determine the extent of differences between Snapdragon 690 and other members of Qualcomm’s 6 series that have been released on the market in the last one or two years, it is better to take a look at the table below; Where the differences between SD690 and other 6 series platforms can be clearly seen not only in the communication sector but also in the field of processing, graphics and lithography.


Snapdragon 690 is made with 8nm lithography and this time, like SD675, it works at the level of the best processors in the market in terms of the selection of processing cores. The processing in this chipset is done with two high-level cores with a frequency of 2 GHz and 6 low-level 1.7 GHz cores, as in the previous two generations, i.e. Snapdragon 670 and Snapdragon 675 is also repeated, but with the difference that this time from high-level cores Cortex-A77 is used for two more powerful cores, which, according to the manufacturer, is 20 The percentage of processing power is higher in this processor. 6 cores of 1.7 GHz A55 have remained unchanged in the meantime.


Qualcomm has also made extensive improvements in the field of graphics and instead of the not so powerful Adreno 612 graphics present in Snapdragon 675, it has used a new GPU called Adreno 619L, which according to the manufacturing company improves performance and efficiency by 60%. Leads. The power of this new graphics in many cases can even be achieved with Adreno 620 in Snapdragon 765G compared and in this sense faced with the power beyond the usual practice of 6 series chipsets we will be.


In the memory department, Snapdragon 690 still supports LPDDR4X memory with dual 16-bit channel, which, despite the fact that it creates less bandwidth compared to the advanced processors of the 7 and 8 series, but this amount is still sufficient for current phones. In this price category, it seems quite suitable and satisfactory. The maximum RAM memory supported in this set is 8 GB.


One of the important changes in Snapdragon 690, which also occurs for the first time in Series 6, is the upgrade of the update rate supported by this chipset for the screens of phones equipped with this chipset; The maximum resolution supported by Snapdragon 690 phones is still announced as full HD+, but the refresh rate or update rate in these screens has now been upgraded from 60 Hz to 120 Hz. Support for HDR10 and HDR10+ is another positive point, which was not present in SD675, and the 10-bit color depth and Rec2020 color range are other noteworthy points in this section. For comparison, it is interesting to know that the new 7 series chipset Snapdragon 765G, despite supporting a higher resolution QHD+ for the screen, does not support a 120 Hz refresh rate and to access this feature In Series 7, you should look for the improved version of this processor, which is Snapdragon 768G went.

Video signal processor (ISP)

With the importance of finding the camera resolution again in smartphones even at the low and middle level of the market, the role of the ISP or image signal processor in mobile chipsets is much more colorful than in the past and supports higher camera resolution in single and dual modes. , increasing the chances of the chipset being used in more smartphones. In Snapdragon 690, the Spectra 355L image signal processor is used, which, like Snapdragon 675, supports a single camera with a maximum resolution of 192 megapixels, and for this reason, there is no difference between the two.

By entering the zero shutter delay factor or ZSL, this situation changes slightly and while in Snapdragon 690 in single and dual modes, resolutions of 32 and 16 megapixels can be achieved, respectively, in Snapdragon 675 these values ​​are The arrangement was 25 and 16 megapixels. In other words, the new ISP Spectra 355L present in SD690 compared to Spectra 250L present in SD675 only improves the resolution of the single camera in ZSL mode from 25 to 32 megapixels and there is no change in other resolutions. Single camera resolution in MFNR mode (multiframe noise reduction, a technique for taking multiple photos and combining them to reduce noise) is also unchanged at 48 megapixels on both processors.

In the video recording department, we do not face any particular change in terms of resolution, and the maximum resolution of the video capture is still announced as 4K. But this time, it is also possible to capture 4K HDR video, which was absent in the SD675. In the field of slow motion, the maximum supported resolution in Snapdragon 690 is 720p with 240 frames per second, which was also present in Snapdragon 675, with the difference that this time we are talking about 1080p resolution with 120 frames per second, which means the maximum resolution of SD675 slow motion. There is no discussion here.

Artificial intelligence

For the first time, Snapdragon 690 uses the fifth generation of Qualcomm’s artificial intelligence engine and Hexagon Tensor Accelerator, which provides new smart features in many cases; Among these things, it should be mentioned the movement and smooth transition of the image while moving between ultra-wide, wide and telephoto cameras in the user interface of the camera, which according to the video below, unlike in the past, was not done in a stepwise and interrupted manner, and was completely smooth and without any problems. Accepts.

Improving nighttime imaging is another AI-related item in this collection, which was developed in collaboration with Qualcomm and ArcSoft and the long-term exposure technique. Blurring the background in photos and videos with the help of ArcSoft’s advanced single-camera artificial intelligence portrait engine is another aspect related to AI in Snapdragon 690, which, apart from image beautification, also plays a significant role in improving privacy during video conversations. he does. These two items can be seen in action in the video below. + to create a new level of detail in the 3D avatars of users and personalize as much as possible and Sensory + to intelligently recognize the type of sounds in the environment, process in the device and make intelligent decisions related to each sound. They form this section.

Communication options

Apart from all the things mentioned in relation to Snapdragon 690, surely the most important change and the most attractive feature in this mobile platform belongs to its internal 5G modem, which happened for the first time in a 6 series processor and It will certainly play an effective role in increasing the access of users to the 5G network in the coming months. “We are driving the abundance of 5G in multiple categories to make it available,” said Cristiano Amon, president of Qualcomm, noting that more than 375 5G designs are currently built or under development with Qualcomm’s 5G solutions. We are mostly the next generation of camera, artificial intelligence and game experiences.” According to Amon, the transfer of 5G technology to the 6 series of Snapdragon processors provides a huge potential to reach more than 2 billion smartphone users worldwide to this new communication network.

Snapdragon X51 communication modem in SD690 is designed internally and supports 5G sub-6GHz network; This, of course, implies that the more advanced and faster mmWave technology is not supported in this chipset, and apparently this technology will still remain exclusive to Qualcomm’s more expensive 7 and 8 series processors. The maximum connection speed of the 5G network in Snapdragon 690 reaches 2,500 Mbps in download and 660 Mbps in upload using the 100 MHz spectrum, and in the 4G LTE network, we face the maximum download and upload speeds of 1,200 Mbps and 210 Mbps, respectively.

Among other positive points regarding the communication part of this processor, it should be mentioned that it supports Wi-Fi 6 or ax, which uses the company’s Qualcomm FastConnect 6200 system. Support for NFC, Bluetooth 5.1 with aptX capability and GPS/GLONASS/BeiDou/Galileo/QZSS/NavIC/SBAS routers with dual frequency support are other things that can be mentioned in the communication section of this chipset.

According to Qualcomm, the collections of HMD Global, LG Electronics, Motorola, Sharp, TCL and Wingtech are among the companies that are OEM or ODM. They will launch smartphones with Snapdragon 690. Of course, the list of smartphone manufacturers based on this processor is not limited to these, and probably other companies will be added to this group in the future. According to the company, the Snapdragon 690 will be available in the second half of this year.
