According to Qualcomm, the Snapdragon 8 Gen 2 has the following eight features.
◆1: AI function
The Snapdragon 8 Gen 2 is equipped with a Qualcomm Hexagon processor whose performance such as natural language processing (NLP) is up to 4.35 times faster than before, and is the first AI standard called 'INT4' for the Snapdragon series. corresponded to This gives the Snapdragon 8 Gen 2 60% more performance per watt and 90% more overall performance than its predecessor.
◆ 2: Correction of images and movies in real time
Snapdragon 8 Gen 2 with enhanced AI functions can now use 'real-time semantic segmentation' that can make corrections in real time by recognizing elements contained in photos and videos and optimizing them individually. rice field.
As a result, the original photo (left) can be made into a photo (right) with outstanding shadows and colors in real time as shown below.
◆3: Ray tracing
The Snapdragon 8 Gen 2 also has a full range of game functions, and the ray tracing function allows you to play games with realistic graphics. In addition, the power efficiency has been improved by up to 45%, and the performance of the 'Qualcomm Adreno GPU' has been improved by up to 25%, so the compatibility between performance and battery life has been strengthened more than ever.
Comparing the screen with ray tracing off (top) and the screen with ray tracing on (bottom), you can see that there is a big difference in the depiction of the light reflected on the water surface at the bottom of the screen.
◆ 4: Corresponds to MetaHuman of Unreal Engine 5
From Snapdragon 8 Gen 2,
◆ 5: New architecture CPU
Snapdragon 8 Gen 2 is equipped with the latest CPU 'Qualcomm Kryo CPU' with a unique architecture of 1 prime core, 4 performance cores, and 3 efficiency cores. Replacing one of the four Snapdragon 8 Gen 1 efficiency cores with a faster performance core allows the Snapdragon 8 Gen 2 to pursue speed while maintaining optimal power efficiency. became.
◆ 6: 5G performance
The Snapdragon 8 Gen 2 uses the Snapdragon X70, a 5G compatible modem with a built-in AI processor. By improving the downlink with AI technology, the effect of multipath , in which radio waves bounce between buildings and reach the terminal on different routes, is reduced, so communication performance in urban areas with dense buildings is reduced. In addition to being greatly improved, the accuracy of location information has also increased.
◆ 7: Spatial audio with head tracking
New to the Snapdragon 8 Gen 2 is support for a 'spatial audio' feature with dynamic head-tracking technology that changes the sound according to the movement of the user's head. As a result, when you wear compatible earphones and move your head, the sound will move accordingly, so the immersive feeling of movies and games will be enhanced in terms of sound.
◆ 8: Security
Snapdragon Secure, a security function that protects Snapdragon 8 Gen 2, incorporates biometric detection technology jointly developed with TrinamiX, a German sensor manufacturer, so that spoofing using photos and 3D models is more reliable than ever before. can now be prevented.
According to Qualcomm, smartphones equipped with Snapdragon 8 Gen 2 will appear in 2022, and partner brands include Sony, Sharp, ASUS Republic of Gamers (ROG), Honor, Motorola, OnePlus, Oppo, and Xiaomi. , ZTE, etc. are listed.
