    Qualcomm unveiled its latest mid-range processor, the Snapdragon 778G, on Wednesday, May 19, 2021; This mobile platform, which compared to its predecessor, the Snapdragon 765G, and its overclocked version, the Snapdragon 768G, offers dramatic and extraordinary changes in all three parts of the processor, graphics and lithography, is very similar to the new 5nm Snapdragon 780G chipset. Some differences between the two should be sought in graphics and ISP related issues. The Snapdragon 778G appears for the first time in the Honor 50 and is gradually appearing in other mid-range phones. Introducing the Snapdragon 778G with 6nm lithography and LPDDR5 support

    Snapdragon 778G is Qualcomm's first experience in making 6nm processors; A category that MediaTek has already entered with the Dimensity 1200 and Dimensity 1100 chipsets, and Qualcomm's presence in this category will lead to a fiercer competition among the makers of mid-range handsets. Although in some cases, such as lithography, this chipset is lower than the Snapdragon 780G, but in the field of 5G with mmWave and in the field of RAM with support for LPDDR5, it performs better than its bigger brother.

    The Snapdragon 778G structure's apparently uses a very similar set to the SD780G, with heavy-duty 4-core Kryo 670 (based on the Arm Cortex-A78) and lighter processing assigned to the A55's four cores. Has been. Qualcomm did not specify the layout and frequency of each of the processor cores, but only at a maximum frequency of 2.4 GHz. Some sources have described the processor's more advanced cores as similar to the SD780G, with one 2.4 GHz A78 core in the advanced category and three 2.2 GHz A78 cores in the middle category. Qualcomm still points to the 40% higher performance of this suite, which is probably measured compared to the Snapdragon 768G, without further explanation. Introducing the Snapdragon 778G with 6nm lithography and LPDDR5 support

    while on the Snapdragon 780G For the first time, graphics were used at the level of the flagship 8 Series models called Adreno 642, in the SD778G we find a seemingly similar graphics called Adreno 642L, in which the suffix L refers to the weaker graphics, as in Qualcomm's usual practice, while in The Adreno 642 was a 50 percent improvement over the previous generation, with the Adreno 642L upgrading to 40 percent. The reason for this, more than anything else, is apparently to be found in the lower frequency of the graphics cores, and we do not see any change in the nature of the graphics.

    The structure of this series supports some of the features associated with the game called Snapdragon Elite Gaming Features, including variable rate shading (VRS); A feature that prevents excessive battery consumption while ensuring high visual quality. Game Quick Touch is less than the other supported features in this part, with an increase in the call response rate in games and a 20% delay.

    The graphic story is repeated in the video signal processor or ISP section, and while the Snapdragon 780G used Spectra 570, the ISP in the SD778G was renamed Spectra 570L; This ISP, of course, is like the example in the Snapdragon 888 and Snapdragon 780G triple type and can receive information from three cameras simultaneously. The 778G ISP, according to Qualcomm, is capable of processing 2 gigapixels per second, which is slightly less than the 2.5 gigapixels announced for 780G.

    Supported single camera with zero shutter delay (ZSL) on the Snapdragon 778G is 64 megapixels, down from 84 megapixels on the SD780G. If the number of cameras in the same mode increases to two, the maximum resolution is 22 + 36 megapixels, and receiving information from three cameras with this processor with zero shutter delay also requires a maximum of 22 megapixels of these cameras. It should be noted that the Snapdragon 780G in dual camera mode with zero shutter delay can serve two 20 + 64 megapixel cameras, and triple cameras in this mode can also be 25 megapixels each.

    The Snapdragon 778G supports a single 192-megapixel camera with zero shutter delay, no different from the 780G. In terms of maximum video resolution, we do not see any change, and 4K resolution is still supported in HDR mode with 10-bit color depth.

    The AI structure of this mobile platform has apparently not changed from 780G and is still in the same design as the Snapdragon 888 from the sixth generation of Qualcomm AI engine with Tensor accelerators and scalar and vector engines. Execution engines) all support a common DSP block called the Hexagon 770, providing 12 trillion operations per second. Introducing the Snapdragon 778G with 6nm lithography and LPDDR5 support

    one of the few 778G advantages over 780G should be searched in the type of RAM supported by this processor; This is where, for the first time, Qualcomm 700 Series mobile platforms support LPDDR5. This option, which was not included in the Snapdragon 780G, now allows access to a maximum of 16GB of 3,200MHz RAM. For comparison, the Snapdragon 780G supported a maximum of 2,133MHz LPDDR4 RAM. Snapdragon X53 communication modem This is the same model that was present in the SD780G, but this time it is possible to connect to 5G networks of both mmWave and sub-6GHz, and its maximum download speed on paper from It has increased from 3.3 Gbps to 3.7 Gbps. This modem, of course, still does not offer 5G on both SIM cards like other previous Qualcomm experiences. The FastConnect 6900 vs. 780G system has now been replaced by the FastConnect 6700, both of which support Wi-Fi 6E, and apparently the only difference is the maximum WiFi 6 connection speed of 3.6 Gbps on the 6900 and 3 Gbps on the 6700. Bluetooth 5.2 is also naturally present in this platform and also supports NFC, USB connection with USB 3.1 speed standard and dual frequency satellite routers. Of course, it is important to note that, as usual, manufacturers are free to choose between Wi-Fi and Bluetooth chips, and thus will not guarantee the presence of all these features in the final products.

    In the section of fast battery charging, we should also mention the presence and support of Qucik Charge 4 +, the 100-watt power of which is theoretically possible to charge the battery very quickly.

    Snapdragon 778G in the second quarter of this year Launched and marketed by Motorola, Riley, iQOO, Xiaomi, Honor and Oppo as manufacturers that launch the product or products with the Snapdragon 778G. From this group, Honor brand and Honor 50 phone are apparently the first candidates to receive this processor. Source: Qualcomm
