Arm announces 'Arm ASR' technology that reduces smartphone battery consumption while achieving high-quality game rendering

Arm has announced ' Arm Accuracy Super Resolution (Arm ASR) ,' a technology that enables high-quality game rendering while reducing the load on the GPU. In tests conducted by Arm, it has been confirmed that it is possible to reduce smartphone battery consumption while maintaining the rendering quality of the game.

In PC games, multiple game super-resolution technologies such as NVIDIA's ' DLSS ', AMD's ' FidelityFX Super Resolution (FSR) ', and Intel's ' XeSS ' have appeared, creating an environment in which games can be rendered in high quality while reducing the load on the GPU. On the other hand, in the smartphone market, there is a super-resolution technology called Qualcomm's ' Snapdragon Game Super Resolution (GSR) ', but the number of games that support it is currently small.

Arm's super-resolution technology 'Arm ASR' is based on AMD's open-source 'FSR 2' . For this reason, game developers can use the code they have accumulated for FSR 2 to work on Arm ASR. In addition, Arm ASR achieves high-quality super-resolution by incorporating the function included in FSR 2, 'extracting information from multiple frames and generating new frames'.

The images below show, from left to right, 'high-resolution frames drawn without using super-resolution technology,' 'high-resolution frames generated from low-resolution frames with Arm ASR,' 'high-resolution frames generated from low-resolution frames with FSR 1,' and 'high-resolution frames generated from low-resolution frames with GSR.' When you check the images, you can see that Arm ASR is capable of high-quality super-resolution compared to FSR 1 and GSR.

Below are the results of verifying the performance of Arm ASR on the Arm smartphone GPU '

Immortalis-G720 '. When performing the drawing process of 'generating frames of the desired resolution from frames of half resolution using Arm ASR', the frame rate is 53% higher than the drawing process of 'generating frames of the desired resolution without using super-resolution technology'.

In addition, the results of measuring the power consumption during game rendering using a device equipped with MediaTek's smartphone SoC '

Dimensity 9300 ' are below. Using Arm ASR reduces the power consumption of the GPU (green), which ultimately reduces the battery consumption of the entire device.

Arm plans to release the Arm ASR source code under the MIT license in the future.
