Arm Neural Super Sampling Set To Bring DLSS-Style Upscaling To Mobile GPUs

At SIGGRAPH 2025 today, Arm pulled the wraps off Neural Super Sampling (NSS), its first AI-driven upscaling technology designed for mobile GPUs. It's the debut application of "Arm neural technology," a planned set of features for future Mali GPUs with integrated neural accelerators. The promise is that of "desktop-class graphics" at lower power on mobile platforms, by rendering at a fraction of native resolution and using AI to fill in the detail.

If that sounds a lot like NVIDIA's DLSS, AMD's FSR4, and Intel's XeSS, that's because it is a lot like those. The pitch is straightforward: render at a lower resolution (in Arm's go-to example, 540p internal → 1080p output), run the frame through a trained neural network, and output something that looks close to native while using far less GPU time.

Arm is framing this as an "industry first," but the "industry" here ...
