- AMD argues that x86 processors can match Arm's efficiency in notebooks while maintaining the x86 software ecosystem.
- AMD claims the overall system package, not the ISA, determines power efficiency and battery life.
- AMD previously considered Arm ISA with K12 but chose x86 due to software advantages.
- Arm's market share in PCs is growing but still insignificant compared to x86.
- AMD discontinued K12 to focus on Ryzen and EPYC under CEO Lisa Su.
- ARM architectures are optimized for lower power usage, but this isn't inherent to the ISA.
- x86 could theoretically be efficient in mobile, but development costs and competition make it impractical.
- Compatibility issues with native code hindered x86 adoption in smartphones.
- ARM Windows laptops face high return rates due to compatibility and pricing issues.
- Intel's thermal protection features surpass AMD's, allowing operation without a heatsink.
