Shulou(Shulou.com)11/24 Report--

Snapdragon Elite Gaming is committed to creating a great gaming experience for every user. Snapdragon supports many end-game-level features, including the 144FPS gaming experience and ultra-smooth graphics with the highest visual quality supported by True 10-bit HDR, allowing players to enjoy a gaming experience of more than 1 billion colors. Snapdragon has introduced many mobile pioneering features into players' favorite games, including real-time light pursuit based on hardware acceleration, support for the latest upgrade of Unreal engine 5, variable resolution rendering (VRS), Vulkan 1.3, and many other features.

Today, Qualcomm continues to lead the trend in mobile gaming technology with the introduction of a new feature of Snapdragon Elite Gaming-Snapdragon Snapdragon Game Super Resolution ™(Snapdragon GSR), which fully unleashes game performance and leads to longer battery life.

What is the super resolution of the game?

At present, there are a variety of technologies that can improve the game from a lower resolution to a native resolution, which can achieve better performance while reducing power consumption. Bilinear interpolation is the most commonly used stretching algorithm in mobile games, which has the highest performance but can lead to blurred output images. The current time-domain stretching algorithm can improve the image quality, but it needs more input information, so the performance of the mobile phone platform will be very heavy.

Figure 1: the original resolution (1080p) is compared with a 2x improvement in image quality using Snapdragon game overscoring and bilinear interpolation techniques, respectively. Here, the resolution of the input image is half that of the output image.

What is the super resolution (super score) of Snapdragon game?

Snapdragon Game Superscore is a single-channel space-aware hyper-scoring technology developed by Qualcomm's internal Snapdragon Game Studio. It can save power consumption and achieve the best game picture quality improvement under the condition of fully releasing performance.

The Snapdragon Super single Channel solution, which is available for the first time, is the latest feature for mobile and XR games, which can be used to maximize the game performance and battery life of Snapdragon terminals and is currently available to major partners. While it is compatible with most GPU, it also provides the best performance on Snapdragon platform.

How does the Snapdragon game super score improve the game experience?

Snapdragon Game Super score for smartphones and XR devices brings many improvements to the gaming experience:

1. Improve resolution while maintaining visual quality of graphics

two。 Increase the frame rate to achieve a smoother gaming experience

3. Reduce power consumption and achieve longer battery life

4. Improve visual fidelity while maintaining frame rate

With the Snapdragon game super score, the 1080p game quality can be improved to a sharper 4K. Originally only 30FPS games can show the effect of 60+FPS, the graphics are more smooth. As the performance is closely related to power consumption, players can not only make use of the above features, but also play for a longer time.

Snapdragon Super score allows players to achieve higher resolution, faster frame rate or more lasting battery life according to their personal preferences when playing mobile games.

How does the Snapdragon game overscore work?

Snapdragon game overscore is a space-based single-channel pixel multiplication technology optimized for Snapdragon Adreno GPU. It customizes range-based dynamic resolution enhancement technology for Adreno GPU pipelines to achieve excellent graphics quality and reduce power consumption. In general, compared with other mobile solutions that improve resolution, Snapdragon can achieve a 2-fold performance improvement.

The following figure shows the performance comparison of Snapdragon game super score with other leading resolution improvement technologies for different resolution input targets:

As shown in the following figure, in addition to better performance, the Snapdragon game super score can also bring excellent visual quality and graphics processing power close to the game's native rendering.

Snapdragon game super score how to achieve speed improvement on Snapdragon hardware?

The Snapdragon game uses as few registers, texture sampling instructions, and arithmetic logic unit (ALU) instructions as possible on Adreno hardware.

Other resolution enhancement techniques use at least two channels on the input image, which increases the bandwidth used in the resolution improvement process. The Snapdragon game overscore integrates resolution improvement and edge sharpening into one channel, reducing latency and reducing the use of memory bus, thereby reducing power consumption and improving speed.

Snapdragon's super-scored single channel can be merged with other post-processing channels (such as tone mapping) to further improve performance.

In addition to using a single channel, Snapdragon uses fewer ALU instructions and texture sample sampling than the competition, achieving higher shader processor utilization, thereby reducing frame time and power consumption.

In the Snapdragon game, the weight is calculated by the convolution core of 12 pixels acting on the luminance map of the input image, and the brightness is approximately obtained by the green (G) channel of the input image, because the human eye is the most sensitive to green.

Therefore, when calculating each pixel, the Snapdragon game super-scoring technology performs single-channel texture sampling of 12 pixels in the input image and three-channel texture sampling of 1 pixel, with a total of only 15 texture sampling instructions-Adreno GPU can completely hide the delay of these texture sampling, achieving 100% shader processor utilization.

The performance of the above results on the relevant Snapdragon mobile platform terminals is summarized as follows:

Mobile games and XR products that support Snapdragon's super-scoring technology are expected to be released later this year.
