Qualcomm's event “Snapdragon Tech Summit” announced the new lineup of mobile SoC “Snapdragon”. FlagshipSnapdragon 865 Mobile Platform”And the three Snapdragons that were revealed, while predicting the specs,“ 5G smartphone equipped with the latest Snapdragon ”expected to appear around the first quarter of 2020 [January to March] Let's try.
Smartphone with Snapdragon 865/765 / 765G, here changes
The new SoCs include the flagship 8 series “Snapdragon 865”, the high-end 7 series standard “Snapdragon 765” and the mobile gaming terminal “Snapdragon 765G”. The Snapdragon 765G is about 10% more powerful in graphics processing.
Each SoC features powerful multi-mode 5G support. The Snapdragon 765 / 765G has a built-in 5G modem IC, while the Snapdragon 865 has a separate modem IC "Snapdragon X55 5G Modem-RF System".
In the flagship Snapdragon 865, the 5G modem is not integrated. “We didn't want to compromise on the performance of either the application processor or the modem,” said Qualcomm President Christiano Amon.
The 7 series Snapdragon 765 / 765G scales down the application processor and modem compared to the 8 series to provide an integrated 5G-ready platform. The maximum communication speed [theoretical value] of 5G communication is about half of the performance of Snapdragon 865 with 7.5 Gbps downlink and 3 Gbps uplink, while 3.7 Gbps downlink and 1.6 Gbps uplink. As for the bandwidth of 5G millimeter wave and Sub-6, the 8 series has twice the performance of the 7 series.
Alex Katouzian, head of Qualcomm's mobile department, attended the roundtable that gathered the press, added:
“Neither series is compromised in the sense of providing the best performance for the targeted audience, while keeping the architecture as simple as possible while providing the best performance for each specification.
Snapdragon 865 should be a flagship that can fully perform both communication and application processing for the arrival of the full-fledged 5G era. That ’s why I avoided integrating the application processor with the modem. ”[Alex Katouzian]
■ It seems to be safe to use during the transition from 4G to 5G
The new Snapdragon series SoCs have a variety of 5G solutions to enable flexible support during the transition from 4G to 5G. Dynamic spectrum sharing [DSS], inter-band carrier aggregation, and global 5G roaming that enable 4G and 5G deployment on the same frequency band.
In 2020, commercial 5G services will also be provided from each telecommunications carrier in Japan. If you purchase a smartphone with the latest Snapdragon, you can use the high-speed communication service safely and comfortably in Japan and overseas for the time being.
■ Fusion of smartphones and voice UI is accelerating. Convenient real-time translation of foreign languages
As a feature of the new Snapdragon series, "AI performance enhancement" was reported in addition to 5G. The 8th and 7th series are loaded with the latest 5th generation engine of the Qualcomm Artificial Intelligence Engine, an AI platform that combines a CPU, DSP, and GPU.
In addition, a sensing function hub “Qualcomm Sensing Hub” that responds to user voice input [wake word] and utilizes sensor information such as voiceprint authentication even when the smartphone is locked is newly established.
With this addition, compared to the current Snapdragon 855, the power consumed when the smartphone is on standby is further reduced, and more wake words can be responded to. There may be a significant increase in the number of things that can be achieved with the voice operation of a smartphone, just like a smart speaker, such as using multiple AI assistants from the screen lock state.
The Snapdragon 865 integrates a new “Tensor Accelerator” into the Hexagon 698 processor that controls AI-related processing, and is about four times as powerful as the current Snapdragon 855. Power efficiency has also been improved by 35%.
Next-generation Snapdragon that has acquired advanced AI processing performance. What was introduced as a terminal equipped with it was fast and accurate character recognition by voice input and real-time translation of foreign languages.
The cloud and edge AI platform will be linked to the 5G high-speed network, and the smartphone will become a pocket-sized portable translator. The expectation that the day when everyone can communicate smoothly with people who speak different languages will soon come.
■ Camera has been seen as "8K compatible"
The camera functions of smartphones are likely to become increasingly rich with the new Snapdragon series. In particular, the Snapdragon 865 image processing engine “Spectra 480” attracted attention for its powerful performance.
The camera functions exemplified by Qualcomm at this presentation are only to appeal the high performance of the latest Snapdragon 865. In order to actually realize it on a smartphone, it is necessary to have comprehensive capabilities such as lenses, image sensors, and software.
However, “8K support”, which Qualcomm listed as an example, is thought to be the time for the 5G era to arrive, and it will be possible for smartphone cameras to steer the evolution toward 8K. In the demonstration after the presentation, US video WeVideo's “8K compatible video editing app” [prototype for 5G smartphones] was introduced.
4K / HDR compatible high-definition video shooting with smartphone cameras supports HDR10 and HLG from Snapdragon 845, and HDR10 + from the current Snapdragon 855. With the next generation flagship Snapdragon 865, you will be able to shoot 4K / HDR videos of Dolby Vision on your smartphone.
Since this is an optional feature, not all smartphones with Snapdragon 865 will support it, and you may need to obtain a Dolby license as a smartphone manufacturer. At present, however, there is no camera device for consumers that can shoot Dolby Vision HDR video, so the first smartphone equipped with this is likely to get a lot of attention, especially in mania.
■ Snapdragon for mobile games
For gaming entertainment, Qualcomm is particularly focused on. Appealing high affinity with the Snapdragon series. At the presentation, Todd LeMoine, the chief engineer of Qualcomm Gaming, took the stage and introduced SoC performance over a long period of time.
The reason why Snapdragon 865 does not have a special version of the gaming specification that bears “G” is because it can already handle advanced gaming content with its base performance. It was also revealed that smartphones equipped with the Snapdragon 865 can display HDR at 4K / 60Hz and QHD + / 144Hz at maximum.
The latest generation of Snapdragon will be able to update the Adreno GPU driver via the Google Play store. As a function to keep the GPU in the latest condition so that you can enjoy comfortable mobile gaming, it is a place where you are worried about how it will be used after the terminal is released.
■ Wireless audio further improves sound quality and low delay performance
Finally, let's introduce the new features that the new Snapdragon has realized in wireless audio. Wireless functions using Wi-Fi and Bluetooth other than cellular communication are positioned as subsystems as Qualcomm FastConnect, and each function is being enhanced.
Both Snapdragon 8 and 7 series support Wi-Fi 6 [IEEE 802.11ax], commercialized in the fall of 2019. Online games are likely to be played comfortably with minimal delay.
Around Bluetooth, an audio codec “aptX Adaptive” that uses a variable bit rate method is provided as standard as an option of the new Snapdragon series. In the upper Snapdragon 865, the maximum transfer bit rate is enhanced from 48kHz / 24bit to 96kHz / 24bit, and the high-resolution equivalent sound that can be enjoyed with Bluetooth is further enhanced.
"AptX Voice" is newly added to the Bluetooth audio codec as a function that improves the convenience of hands-free calling. By using SWB [ultra-wideband] codec and Bluetooth technology, which are also used for VoLTE voice calls, it is possible to make clear voice calls of up to 32 kHz by sending data from smartphones to headphones and earphones equipped with decoders. . Smartphones that improve the quality of hands-free calls even through earphones are likely to be welcomed by users of completely wireless earphones.
5G smartphones equipped with the latest Snapdragon will be announced one after another at the MWC Barcelona 2020 mobile exhibition scheduled to be held in Barcelona, Spain from February 24 to 27, 2020. Sure. Let's look forward to it now.
