Qualcomm reveals Snapdragon 8 2nd generation, which is more powerful with AI

[Hawaii (US) = Won Bong-seok reporter] Qualcomm on the 16th (1 pm local time) on the 16th (2022 Snapdragon Summit, a year-end technology event held in Hawaii, USA, next-generation mobile will be mounted on major Android smartphones from the second half of this year. The application processor (AP) 'Snapdragon 8 2nd generation' has been unveiled.

The Snapdragon 8 2nd generation has spread AI (artificial intelligence), which was limited to some applications, to the whole smartph1. AI is used for multilingual translation, semantic division of ISP (image processor), and 5G communication speed optimization.

Major manufacturers such as Samsung Electronics, Asus, Xiaomi, Opp, One Plus, and Sony will launch the Snapdragon 8 2nd generation smartphone from the end of the year.

■ Improved AI performance with the support of 'INT4', which is mainly used for reasoning

The Snapdragon 8 2nd generation uses AI for all major functions of smartphones such as photos and 5G. Qualcomm has upgraded the qualcomm ai engine, which is dedicated to AI-related operations, to the 8th generation and named it 'Snapdragon Smart' to the related functions.

The built-in hexagon processor processes real-time multilingual translation and AI function to recognize the subject. In addition, INT4 (32-bit), a data type used for reasoning operations, was supported at the chip unit to increase the processing rate.

Qualcomm announced that it has improved the inner architecture of the hexagon processor to improve AI performance up to 4.35 times compared to its predecessor (Snapdragon 8 1st generation).

■ Disassembled by the subject unit and customized processing... 200 million pixel response

With the recent leveling of smartphone computing performance, smartphone camera performance has become a major measure of comparing performance between products.

The Snapdragon 8 2nd generation uses the 'semantic division' that breaks down the main subjects from the camera sensor to break down the face, hair, clothes, and sky, which is a semantic split that fits each subject.

The Snapdragon 8 2nd generation finished the preparation for more than 200 million pixels in the number of pixels, which is as important as the quality. Samsung Electronics supports the 200 million pixel sensors 'Ispell HP3' developed in June.

Qualcomm announced last year that it will be operated by Sony Semi-Condur Solution, the world's No. 1 camera sensor company, with a joint research institute that studies camera sensors. snapdragon optimization sensors, developed in collaboration with both companies, are also supported.

■ Implementation of real-time rate racing in mobile games... AV1 codec also supports

The Snapdragon 8 second generation also adds ray tracing to increase graphic quality in addition to the frame number (FPS) per second, which is mainly used as a performance indicator of mobile games.

Rate racing function is a technique that expresses the shadows and reflective light that occurs when various light beams such as sunlight, bulbs, and torches touch objects.

It was thought that it was impossible to deal with it in real time before 2018, but now it is widely used in the graphics card for mainstream PCs. Qualcomm has increased the arena GPU performance up to 25% and the rate racing processing with hardware.

It also supports AV1, an open source codec adopted by global Internet companies such as Google (YouTube), Netflix, and Microsoft as the next-generation industry standard. Qualcomm explains that 8K (7680 × 4320) resolution and HDR video will be played up to 60 frames per second.

■ Dual 5G Shim Intelligent conversion, Wi-Fi 7 degrees support

The X70 5G modem, which is built in the Snapdragon 8 2nd generation, has two 5G networks or two 5G and 4G networks, and then has the ability to connect the AI to the optimal network by determining the sensitivity and network situation.

Wi-Fi 7 (802.11be), the next generation Wi-Fi standard that will be 6 · 6e Wi-Fi, is also supported using Fast Connect 7800.

Wi-Fi 7 utilizes both 2.4/5/6GHz frequency band and increases the maximum transmission speed to 30Gbps. However, there is no product that formally supports Wi-Fi 7 among the commercial wired and wireless routers, but it is expected to be only 6 · 6E for the time being.
