AMD Brings Lightweight FSR 4 AI Upscaling to Handheld APUs

AMD $AMD is officially expanding its machine learning-based FSR 4 upscaling technology to handheld devices, APUs, and gaming laptops by the end of this year. The announcement marks a strategic reversal for the chipmaker, which had previously expressed skepticism about shrinking the AI-driven upscaler to fit the strict power envelopes of portable gaming devices. While the lightweight FSR 4 model will support both existing and upcoming APU architectures, the company has refused to confirm whether the feature will be retroactively enabled on older legacy handhelds. "We will expand the machine learning AI-based FSR4 technology, which was first introduced to existing external graphics cards, to the entire product line, including APUs, gaming laptops, and handheld devices, by the end of this year." — Jack Huynh
