Microsoft may launch Surface PCs with AMD's Arm-based chips in 2026

According to recent leak by a trusted source KeplerL2, on NeoGaf, a video game discussions page, Microsoft could be expanding its Surface lineup with new AMD’s Arm-based chip (code name Sound Wave). He said, “Soundwave is made for the 2026 MS Surface lineup.”

What we know so far

Well, the official details are scarce, but KeplerL2’s comment points towards Microsoft intention to strategically diversify beyond Intel and Qualcomm.

AMD’s Arm-based processors, produced using TSMC’s 3nm process technology, are expected to be the successors to the Surface Laptop 7 and Surface Pro 11 models, potentially at a lower price than current Surface models.

Rumor has it that Sound Wave will be an APU featuring:

• 6 CPU cores: 2 performance + 4 efficiency cores
• Integrated GPU: 4 compute units, based on RDNA 3.5 architecture
• Memory controller: 128-bit LPDDRx-9600 RAM
• Thermal envelope: Optimized for 5-10W, ideal for ultra-portable devices like Surface Go or Surface Hub

The configuration indicates that the chip will likely priortizes power efficiency and thermal performance, which means longer battery life at a lower cost.

Is it a trade off in performance?

Compared to Qualcomm’s Snapdragon X Elite, this upcoming chip, Sound Wave is expected to deliver lower performance, which may not align with Surface devices, considering users expecting premium tier performance from the brand.

However, with the existing Surface laptops equipped with Snapdragon X series chips and the addition of a new AMD Arm-based processor devices could broaden the lineup, giving customers a wider range of options to choose from based on their needs.

If this rumor turns out to be true, AMD entry into the Arm-based Windows PCs range via Surface lineup could a big milestone. Also, it shows Microsoft intent to expand its Arm ecosystem, and position itself competitively against with Apple’s M-series chips.
