The original FP8 matrix acceleration requirement had limited FSR to Radeon RX 9000 and later RX 7000 cards; the laptop version of the INT8 model is reportedly less than half the size of the full model. Early tests indicate better reconstruction from lower internal resolutions for Series S developers, at a small performance cost on older GPUs.", "body_md": "AMD's ML-based upscaler originally needed FP8 matrix acceleration, which kept it on Radeon RX 9000 and later RX 7000 cards. FSR 4.1 changes that: the neural network model has been adapted to run on INT8 shader support, and according to technical reports the version for laptops is less than half the size of the full model.\n\nWhat's available now and what isn't:\n\nFor developers targeting Series S in particular, better reconstruction from lower internal resolutions is the interesting part, with a small performance cost on older GPUs according to early tests.\n\nFull story on Tadna: [https://www.tadna.com/en/news/amd-enables-fsr-41-on-xbox-series-xs-and-ally-laptops-via-26101-drivers?utm_source=dev&utm_medium=social&utm_campaign=tadna](https://www.tadna.com/en/news/amd-enables-fsr-41-on-xbox-series-xs-and-ally-laptops-via-26101-drivers?utm_source=dev&utm_medium=social&utm_campaign=tadna)", "url": "https://wpnews.pro/news/fsr-4-1-reaches-rdna-2-hardware-by-switching-to-an-int8-model", "canonical_source": "https://dev.to/tadnaen/fsr-41-reaches-rdna-2-hardware-by-switching-to-an-int8-model-ff7", "published_at": "2026-10-21 11:31:42+00:00", "updated_at": "2026-10-21 11:40:22.478310+00:00", "lang": "en", "topics": ["machine-learning", "ai-infrastructure"], "entities": ["AMD", "FSR 4.1", "RDNA 2", "Radeon RX 9000", "Radeon RX 7000", "Xbox Series S", "Xbox Series X", "Tadna"], "also_reported_by": [], "alternates": {"html": "https://wpnews.pro/news/fsr-4-1-reaches-rdna-2-hardware-by-switching-to-an-int8-model", "markdown": "https://wpnews.pro/news/fsr-4-1-reaches-rdna-2-hardware-by-switching-to-an-int8-model.md", "text": "https://wpnews.pro/news/fsr-4-1-reaches-rdna-2-hardware-by-switching-to-an-int8-model.txt", "jsonld": "https://wpnews.pro/news/fsr-4-1-reaches-rdna-2-hardware-by-switching-to-an-int8-model.jsonld"}}
