Arm introduces ASR upscaler for mobile devices
Arm is launching its own Arm Accuracy Super Resolution (ASR) upscaler for mobile devices. The developer claims that its technology can improve the image quality in games while reducing smartphone power consumption. It is reported by The Verge.
Arm has created a technology based on AMD’s FidelityFX Super Resolution 2 (FSR 2) that uses temporal scaling to increase frame rates. Unlike spatial upscaling, which zooms in on a single frame, temporal upscaling uses multiple frames to reduce noise.
Both FidelityFX Super Resolution and Arm Accuracy Super Resolution are open source under the MIT license.
Arm has published the results of its own benchmarks comparing other upscalers on the Immortalis-G720 mobile graphics chip.
Arm claims that ASR delivers 53% higher frame rates than native resolution rendering on a device with an Arm Immortalis-G720 GPU and 2800 x 1260 display, outperforming AMD FSR 2 and Qualcomm’s GSR.
The company also tested ASR on a device with MediaTek’s Dimensity 9300 chip and found that rendering at 540p and scaling with ASR consumes much less power than running the game at native 1080p.
