AMD Debunks x86 Inefficiency Myth at IFA 2025

At IFA 2025 in Berlin, AMD challenged the notion that x86 architecture is inherently inefficient. They argued that x86 processors (both AMD and Intel) offer competitive battery life in laptops while leveraging the decades-long x86 software ecosystem. AMD claimed the overall package value, not the instruction set, drives power efficiency and battery life, citing designs like Intel's Lunar Lake and AMD's Strix Point as examples. While Arm is slowly gaining traction in the PC market with players like Qualcomm and Nvidia, x86 remains dominant, countering the long-held belief that Arm ISAs are inherently more efficient.
