    Introducing the Qualcomm Snapdragon 780G 5nm intermediate processor
    29 Days, 20 Hours ago

    In December 2019, Qualcomm unveiled the mid-range chipset called Snapdragon 765G, which was named one of the company's most successful mobile processors and played an important role in 5G learning by appearing in dozens of different handsets. The company announced on Thursday, March 25, 2021 (April 5, 1400) a new replacement for this processor called Snapdragon 780G, which continues to pursue the idea of ​​using some of the features of the flagship 800 series chipsets in a more economical set. The Snapdragon 780G has been upgraded in many ways, including new processor architecture, graphics, ISP‌, and connectivity, and we can hope for a bright future.


    Qualcomm later joined the mid-range advanced processor companies, and Samsung and MediaTek introduced the Exynos 1080 and Dimensity 1200 chipsets months ago, respectively. November 2020 and January 2021 were introduced. Of course, Qualcomm's late presence in this field does not mean its poorer performance, and although to identify the strengths and weaknesses of each of these competitors, their performance should be compared in a real device, but given Qualcomm's brilliant history and a look at the specifications of all three processors From the outset, we can talk about the better condition of the SD780G in many cases. First of all, it might be better to see an overview of the Snapdragon 780G compared to the Snapdragon 765G in the table below. �

    While in all three previous generations of the 700 Qualcomm series of relatively old Cortex cores -A76 was used, the Snapdragon 780G finally went to the newer Cortex-A78 cores and used them behind the Kryo 670; The number and arrangement of these cores are different from the previous generation and different from Snapdragon 765G, which had only one A76 core in the main and middle cluster, in Snapdragon 780G, just like the flagship 800 series chipsets from 1 A78 core with 2.4 GHz frequency in the main cluster. And 3 other similar cores with a frequency of 2.2 GHz are used in the middle category, which is a more modern combination. The A55's four low-end cores, of course, have not changed much, and only their frequency has reached 1.9 GHz. Qualcomm described the set as 40 percent more efficient (probably compared to the Snapdragon 768G), with a doubling of the number of more powerful cores certainly playing a key role. �

    Graphics processing task in all three previous members of the series, SD675G, SD765 and The SD768G was hosted by the Adreno 620, and the differences between them were related to things like CPU frequency; In the Snapdragon 780G, we encounter a different situation, where with a big jump to Adreno 642, we enter the realm of the flagship 800 series graphics. The 50% performance improvement (probably compared to the Snapdragon 768G), as the name implies, is close to the Adreno 640 on the Snapdragon 855, despite the obvious difference from the Adreno 660 on the Snapdragon. The 888 still offers much higher performance than Qualcomm's previous mid-range experience. A set of game-related features, such as Snapdragon Elite Gaming Features, is also present here, and through it features such as Game Smoother, Fast Loader, Game Network Latency Manager, Reduction Jank Reducer and some other items are available.

    The Snapdragon 780G supports + 1080p screens with a refresh rate of 144 Hz, making it ideal for advanced gaming with high refresh rates.

    Video signal processor or ISP is one of the most important and determining parts in the structure of a chipset, through which things such as the maximum resolution of the phone's cameras are determined. The Snapdragon 780G uses the new Spectra 570 video signal processor, which allows you to receive images simultaneously from three cameras. The resolution of these three cameras in Zero Shutter Delay (ZSL) mode can be 25 megapixels simultaneously or up to 20 + 64 megapixels in a dual arrangement. Single camera resolution with ZSL is also supported up to 84 megapixels. This resolution can be increased up to 192 megapixels without considering the zero shutter delay in single-camera mode, which is no different from the previous three processors in this series. The chipset also comes with a new architecture for shooting in low light environments, which is likely to have a significant impact on image quality when it comes to process photography.

    The Snapdragon 780G supports 4K video in HDR mode with 10-bit color depth.

    Other strengths of the Snapdragon 780G compared to its competitors include artificial intelligence and digital signal processors; Using Qualcomm's sixth-generation AI engine in a design similar to the Snapdragon 888, Tensor accelerators and scalar and vector execution engines are all integrated into a common DSP block called the Hexagon 770, with a capacity of 12 trillion operations. They provide every second. For comparison, the Snapdragon 768G is 5.4 trillion operations per second, and Samsung's new Exynos 1080 processor is very different from the Snapdragon 780G at 5.7 trillion operations per second. Qualcomm's new chipset is close to the experience of the 800 series flagships in this respect, and for example, it is not much different from the Snapdragon 870 with 15 trillion operations per second. �

    In this section, we should mention the second generation of Qualcomm Sensing Hub series, which The manufacturer plays an effective role in reducing power consumption during voice calls with a background noise cancellation mechanism, thereby providing a better call experience.

    Snapdragon 780G has apparently not changed much in terms of RAM, and in the absence of LPDDR5 still supports 2.1 GHz LPDDR4 memory with a capacity of 16 GB; Which is certainly in order to keep the cost price of the chipset low for its main target market.

    The Snapdragon 780G delivers strong performance in terms of connectivity with the FastConnect 6900 system, which has only been used to date in the latest flagship 800 series processors. Support for Wi-Fi 6E with a maximum download speed of 3.6 Gbps, Bluetooth 5.2 and LTE Cat.24 with a maximum download and upload speeds of 1,200Mbps and 210Mbps, respectively, are the other communication options of this chipset. A subtle point is the type of 5G network supported in the Snapdragon X53 modem of this chipset, which, unlike the previous three members of this family, is only active in sub-6GHz mode and does not support faster and more advanced mmWave network. The removal of mmWave, while at first glance a clear downside to the SD780G, but from another point of view, given the chipset's target market price and mmWave network limitations (currently only available in some countries, including the US), Its presence on a good mid-range chip does not make much sense, and more advanced solutions such as the Snapdragom 870 can be used if you want to replace mmWave. The maximum 5G download speed on the Snapdragon 780G is 3.3 Gbps.

    In the wired communication section supported in this chipset, the USB 3.1 speed standard is mentioned and fast charging is done with the + Quick Charge 4 + standard. The Snapdragon 780G will be available in the second quarter of 2021, according to the manufacturer, and from the very beginning, given the dramatic growth in the price of flagship phones and the problems facing Qualcomm in producing the Snapdragon 888 chipset, the role of color will probably be met. The market will play for flagship mid-range phones. Source: Qualcomm
