Key point

Arm has unveiled Neural Super Sampling (NSS), an AI-based upscaling solution that optimizes mobile GPU performance.

Details

Arm has launched its next-generation AI-based upscaling solution, Neural Super Sampling (NSS). This technology is optimized to run on the Neural Accelerator (NX) of mobile GPUs, boosting real-time rendering performance by reconstructing low-resolution input into high-resolution frames.

NSS is suited for power-sensitive environments such as mobile gaming and XR (Extended Reality). In an actual demo, upscaling 540p video to 1080p reduced GPU load by 50%, with processing time taking just 4ms.

Key support for developers includes the following:

  • A dedicated plugin for Unreal Engine integration
  • Release of the Neural Graphics Dataset for model training and testing
  • Support for experimental environments via Vulkan ML extensions
