AMD FSR 4.1 扩展至 RX 6000 与 Xbox
AMD 宣布其基于机器学习的 FSR 4.1 超分辨率技术扩展至 Radeon RX 6000 系列(RDNA 2)显卡、Ryzen AI Max 与 Ryzen AI 9 处理器以及包括 ROG Xbox Ally 在内的 Ryzen Z2 系列掌机,据 TechSpot 报道该更新包含在 26.10.1 版显卡驱动中。AMD 称已调整神经网络,使其在 INT8 着色器硬件上运行,而不再依赖 RX 9000 显卡的 FP8 矩阵硬件,并为掌机开发了体积不到完整模型一半的版本以适应更紧张的功耗预算。AMD 还确认 FSR 4.1 将登陆 Xbox Series X 与 Series S 但未给出日期,Vulkan API 支持将在 FSR SDK 2.4 中提供,未来会支持更多 APU;此外,代号 Project Helix 的下一代 Xbox 将采用尚未公布细节的 FSR Diamond 技术。
此次扩展让 AMD 最新的机器学习超分技术覆盖数量庞大的 RDNA 2 显卡用户和主机平台,而索尼已在主机端提供 PSSR 与 QSSR,不过 AMD 的画质与帧率说法仍属厂商自述。
Earlier this year, AMD brought the previously RX 9000-exclusive FSR 4 upscaling tech to Radeon RX 7000-series graphics cards and promised an early 2027 release for RX 6000-series products. Christmas has come early for RDNA 2 and many other Radeon gamers, as Radeon honcho Jack Hyunh has announced an FSR 4.1 release for Radeon RX 6000 series cards, Xbox Series X and Series S consoles, Ryzen Z-series handhelds, and machines with Ryzen AI Max and AI 9 chips today.
To accomplish this feat, AMD says it tweaked FSR 4.1's neural network model to support the INT8 shader hardware (as opposed to the higher-precision FP8 matrix acceleration hardware on Radeon 9000 cards). Additionally, the version specific to handhelds is slimmed down even further, to less than half the size of the full one.
AMD says that compared to FSR 3, games on the aforementioned GPUs and APUs will now deliver better image quality, all else equal. With Cyberpunk 2077 running in FSR Balanced mode at 4K, our quick testing with a Radeon RX 6900 XT shows that running FSR 4 costs just about 13% performance, a small price to pay for sharper and more stable visuals, especially in motion.
