Microsoft is set to introduce a new line of Surface PCs in 2026 featuring AMD's Arm-based chip, codenamed Sound Wave. The Sound Wave chip is expected to be an APU with six CPU cores (two for performance and four for efficiency) and an integrated GPU with four compute units based on the RDNA 3.5 architecture, designed for a thermal envelope of 5-10W. This suggests a strategy for low-powered Surface PCs, potentially refreshing the Surface Go or Surface Hub models. This will be the first time since the Surface Laptop 4 that Microsoft incorporates an AMD processor into its Surface lineup. Recently, Microsoft launched new models, including a 12-inch Surface Pro and a 13-inch Surface Laptop, powered by the Snapdragon X Plus, which may outperform the upcoming AMD Sound Wave chip.
