In the world of video games, graphical upscalers are a common thing since the introduction of NVIDIA DLSS. The general idea is that it upscale the graphics from a lower resolution and we can get much more FPS without taking a noticeable hit on the graphical fidelity. And now, Arm has announced its take on this technology – Arm Accuracy Super Resolution, also known as Arm ASR.
Arm’s ASR technology is an open-sourced technology that is based on AMD’s FidelityFX Super Resolution 2 (a.k.a. AMD FSR2), which is also another open-sourced technology. I really love how Arm is taking an open-source project, adding their own spin on it, then making it open-source as well.
Since AMD’s FSR2 is made for PCs and high-end consoles, Arm needed to make some changes to ensure that it works on mobile devices too – and is how Arm ASR is born. Developers who are already familiar with FSR2’s libraries can also easily implement Arm ASR since it’s a derivation.
Arm also showed some in-house FPS numbers collected from a device that is running on the Arm Immortalis-G720 GPU (not the latest) and with a high-resolution display of 2800×1260 pixels.
Having better framerates is only the first benefit of having Arm ASR enabled. We can also expect lowered GPU load, and Arm also provided the numbers for this.
MediaTek, a collaborator of Arm, also provided the numbers for the power consumption test with the Dimensity 9300 chipset. It’s running Bistro Daylist across multiple different resolutions and different ASR settings. Just like AMD FSR2, there is a quality, balanced, and performance mode. The graphical fidelity does change between the three modes.
With lower power consumption means longer battery life, and less heat – and potentially, we can say goodbye to thermal throttling on our mobile devices (at least for some time).
Honestly, I’m looking forward to when game developers start implementing this technology into their games. I’m also looking forward to the next MediaTek chipset that is using the latest Armv9 CSS that was announced in Computex 2024.
