Arm Accuracy Super Resolution (Arm ASR), a new open-source solution for upscaling that has been described by Arm as being best-in-class, is currently in development and headed to mobile devices, Arm has announced. This new solution is derived from FidelityFX Super Resolution 2, an older version of AMD’s upscaling technology, which is now in its third iteration with new features that include frame generation technologies, according to a blog post that Arm shared today with benchmarks that show how the upscalers compare in terms of performance and power consumption.
Arm writes:
- “Our starting point was AMD’s FSR2 upscaler, which produces fine results but with an implementation that is only affordable on PC and high-end consoles.”
- “We derived our solution from FSR2, which means that developers will benefit from the familiar API and configuration options.”
- “The excellent performance of Arm ASR is a combination of highly efficient shader code which reduced both GPU load and bandwidth requirements.”
- “These performance improvements translate into power savings, meaning that users can enjoy longer battery life which is a huge benefit in everyday life.”

Arm on why it was drawn to AMD’s solution:
It is an element of GPUOpen, an open-source project that began in 2016. Working with the permissive MIT license, the intention is to provide portable solutions that ease the burden of addressing the disparities that exist between PC and consoles. These values captured our attention and provoked us to ask ourselves what a good solution for mobile should look like.
