ARM introduces their FSR2-derived Accuracy Super Resolution low-power upscaler
ARM launches their Open Source ASR upscaler for low-power devices
ARM has today introduced their new “Arm Accuracy Super Resolution” (Arm ASR) upscaling technology, which aims to enable high-performance, high-quality gaming possible on low-power devices. This new upscaling solution is based on AMD’s FSR 2 temporal upscaling technology, with ARM tuning their upscaler to deliver more performance to gamers.
AMD’s FSR 2 technology was created for high-performance gaming PCs and consoles. In contrast, ARM Accuracy Super Resolution was made for low-power mobile devices. With ASR, ARM aims to deliver higher quality results than spatial upscaling techniques while delivering higher performance levels of low-power devices.
Below we can see that ASR has a better performance profile than AMD’s FSR 2 technology. The results below come from a device Immortalis G720 GPU with a 2800×1260 screen. Note that ARM has not compared the quality of AMD’s FSR 2 upscaler and ARM ASR. This suggests that FSR 2 may deliver higher quality results.
More Performance, Less Power Draw – That’s ARM Accurate Super Resolution
ARM’s intention with ASR is to deliver stronger upscaling results than spatial upscaling solutions. This must be achieved without taking up too many compute resources or consuming too much power.
By using AMD FSR 2 as a baseline, ARM were able to optimise and adjust AMD’s technology to suit their purposes. This saved ARM a lot of engineering effort. Currently, it is unknown if there is anything that AMD can learn from ARM’s ASR upscaler to improve their FSR2/3 upscalers.
Below is a comparison between a native resolution image, ARM ASR, AMD FSR 1, and Qualcomm’s Game Super Resolution. In the example below, ARM’s solution appears to deliver better upscaling results.
ARM Super Resolution is an interesting addition to the upscaler market. Its performance friendly nature is ideal for low-power devices. However, it likely has image quality downgrades when compared to AMD FSR 2. After all, that added performance needs to come from somewhere.
It is likely that future updates to AMD’s FSR 2/3 upscaling technology will benefit ARM and their ASR upscaler. Perhaps ARM will be able to make their own adjustments that AMD could also benefit from. After all, both AMD FSR and ARM ASR are Open Source. There is nothing that stops upgrades/changes to one upscaler benefitting the other. Is this the start of a mutually beneficial relationship between AMD and ARM?
