Arm Unveils Open-Source Accuracy Super Resolution

Arm has announced the launch of Arm ASR (Arm Accuracy Super Resolution), a game image super-resolution technology that is an open-source solution. It is based on AMD FSR 2 but optimized specifically for mobile terminals to ensure smooth performance on devices with limited capabilities.

In the past, smartphones and tablets typically had smaller screens or lower resolutions, and the graphics performance of their SoCs was limited, resulting in a low demand for super-resolution technology. In recent years, however, this situation has changed with advancements in technology and performance improvements. On one hand, game developers aspire for games to achieve full platform coverage, including mobile platforms. On the other hand, Apple’s M series, initially designed for Macs, has been adapted for smaller devices, enabling high-end AAA titles traditionally run on PCs and consoles to also launch on mobile platforms. Consequently, the need for super-resolution technology support on mobile devices has become urgent.

According to Arm’s test data, due to optimizations for mobile devices, Arm ASR outperforms AMD FSR 2 in terms of performance. For instance, using the Immortalis-G720 GPU, Arm ASR achieved a 53% frame rate increase at a 2800 x 1260 resolution with 2x super-sampling, surpassing AMD FSR 2’s 36%.

Testing with the Dimensity 9300 showed that with 2x super-sampling enabled, power consumption was reduced by more than 20% compared to native 1080P rendering. This effectively lowers device heat generation and extends battery life.

As Arm offers this technology to developers for free under an open-source license, adopting Arm ASR incurs no additional licensing fees. This facilitates the integration of Arm ASR into games, allowing players to enjoy a seamless gaming experience across various terminal devices.
