Introducing Snapdragon 778G with 6nm lithography and LPDDR5 support

News unit EMGblog.com: Qualcomm Company on Wednesday, May 19, 2021 ( 29 May 1400) from its latest mid-range processor called Snapdragon 778G unveiled; This mobile platform, compared to its previous generation, which is Snapdragon 765G and its overclocked version Snapdragon 768G has introduced dramatic and extraordinary changes in all three parts of the processor, graphics and lithography. to the new 5nm chipset Snapdragon 780G is similar and some changes between the two should be looked for in graphics and ISP related cases. Snapdragon 778G appears for the first time in the Honor 50 and gradually appears in other mid-range phones.

Snapdragon 778G is Qualcomm’s first experience in making 6nm processors; A category that was previously Mediatek with chipsets Dimensity 1200 and Dimensity 1100 has entered it and the presence of Qualcomm in this category has made the competition between Manufacturers of advanced mid-range phones will lead. Despite the fact that in some cases, such as lithography, this chipset is inferior to

Processor

In the structure of Snapdragon 778G, apparently, a completely similar set is used compared to SD780G, and here too heavy processing is carried out by 4 Kryo 670 cores (based on A55 assigned Is. Qualcomm did not mention the type of arrangement and frequency of each of the processing cores of this processor and only limited to their maximum frequency of 2.4 GHz. Some sources, thus, the type of arrangement of more advanced cores of this processor is similar to SD780G” means 1 2.4 GHz A78 core in the advanced category and 3 2.2 GHz A78 cores in the middle category. Qualcomm still mentioned the 40% higher efficiency of this processing set, which was probably measured in comparison to the Snapdragon 768G, without further explanation.

Graphics

While in Snapdragon 780G, for the first time, graphics at the level of flagship models of the 8 series, called Adreno 642, were used, in SD778G, we find an apparently similar graphics called Adreno 642L, which The suffix L in it, according to Qualcomm’s usual procedure, indicates that this graphics is weaker, and while in Adreno 642 there was talk of a 50% improvement in performance compared to the previous generation, this upgrade in Adreno 642L has decreased to 40%. The reason for this is apparently to be found in the lower frequency of the processing cores of this graphics, and in terms of the nature of the graphics, we do not face any change.

In the structure of this collection, some features related to the so-called Snapdragon Elite Gaming Features are supported, among which variable rate shading (Variable Rate Shading or VRS) should be mentioned; A feature that prevents excessive battery consumption while guaranteeing high visual quality. Game Quick Touch with increased response rate in games and 20% less delay than other supported features in this section.

Image signal processor (ISP)

The story of graphics is also repeated in the image signal processor or ISP section and while Spectra 570 was used in Snapdragon 780G, the ISP present in SD778G Renamed to Spectra 570L; This ISP is, of course, like the example in Snapdragon 888 and

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

Snapdragon 778G supports a single 192MP camera with zero shutter lag, which is no different than the 780G. There is no change in the maximum video resolution, and 4K resolution is still supported in HDR mode with 10-bit color depth.

Artificial intelligence and digital signal processor (DSP)

The artificial intelligence structure of this mobile platform has apparently not changed compared to the 780G and is still in the same design as the Snapdragon 888 of the sixth generation of the intelligence engine. Qualcomm’s artificial intelligence is supported by placing Tensor accelerators and numerical and vector execution engines (scalar and vector execution engines) all in a common DSP block called Hexagon 770 and provides a capacity equal to 12 trillion operations per second.

RAM memory

One of the few advantages of 778G over 780G should be found in the type of RAM memory supported by this processor; Where LPDDR5 is apparently supported for the first time in Qualcomm’s 700 series mobile platforms. This option, which was not available in the Snapdragon 780G, now provides access to a maximum of 16 GB of 3,200 MHz RAM memory. For comparison, it is enough to know that the Snapdragon 780G supported a maximum of 2,133 MHz LPDDR4 RAM memory.

Communications

The Snapdragon X53 communication modem of this model is the same one that was present in the SD780G, but this time it is possible to connect to 5G networks of both mmWave and sub-6GHz types. Its maximum download speed has also increased on paper from 3.3 Gb/s to 3.7 Gb/s. Of course, this modem is still not able to provide 5G on both SIM cards like other previous experiences of Qualcomm. System FastConnect 6900 Wi-Fi based chips in the 780G are now replaced by FastConnect 6700 data that both support Wi-Fi 6E and apparently the only difference between them is the maximum Wi-Fi connection speed 6 means 3.6 Gbps on 6900 and 3 Gbps on 6700. Bluetooth 5.2 is naturally present in this platform and supports NFC, USB connection with USB 3.1 speed standard and dual-frequency satellite routers. Of course, it is important to mention that according to the usual procedure, the manufacturing companies are free to choose Wi-Fi and Bluetooth chips, and thus, there is no guarantee that all these features will be present in the final products.

In the fast charging section of the battery, it should be mentioned the presence and support of Qucik Charge 4+, the power of 100 watts intended for it theoretically provides the possibility of very fast charging of the battery.

Snapdragon 778G was launched in the second quarter of this year and is from Motorola, Realme, iQOO, Xiaomi, Honor and Oppo is mentioned as manufacturers that market a product or products with the Snapdragon 778G. Out of this, the Honor brand and the Honor 50 phone are apparently the first candidates to receive this processor.
