AMD Downplays ARM Efficiency Advantage While Rumors Hint at Future ARM APUs

The spotlight on ARM architecture is brighter than ever thanks to the successes of Apple’s M series and Qualcomm’s major push into the PC market. ARM chips are widely praised for exceptional power efficiency, with market analysts predicting ARM could become mainstream in laptops by 2030. However, at the IFA 2025 event in Berlin, AMD publicly stated that ARM has no clear advantage over x86 architecture regarding efficiency.

AMD Assert: x86 Can Match ARM Efficiency

Power efficiency matters greatly for battery-powered devices like laptops. Traditionally, ARM was considered more suited for these use-cases. Yet, AMD challenged this view in a recent ComputerBase interview, affirming that “the myth about x86 inefficiency was disproved in 2024.” AMD highlighted that its Ryzen processors and Intel’s Core chips, both based on x86, now offer long battery life in laptops. From AMD’s perspective, x86 chips deliver sufficient efficiency—plus broader ecosystem support and compatibility.

No Advantage for ARM, But Rumored Development Continues

Despite AMD's official stance, industry leaks suggest the company is quietly exploring ARM-based products. For instance, the rumored “Sound Wave” ARM APU could launch for entry-level laptops around 2027, reportedly equipped with a refined RDNA 3.5 GPU. Although AMD asserts there’s no practical advantage for ARM, it may still pursue ARM designs for entry-class devices, aiming to build expertise and minimize risk.

Looking Ahead

While AMD remains publicly skeptical about ARM’s benefits over x86, it appears open to keeping development options available. The company may enter the ARM-based market from the entry level and expand depending on future trends. As innovation continues on both sides, AMD’s dual approach ensures it remains prepared—whether x86 remains dominant or ARM gains further ground in notebook computing.
