ARM’s Cortex A710: winning by default

ARM Ltd has been dominating the Android world for the better part of the last decade, with their 7-series cores at the forefront of their success. Throughout the late 2010s, the Cortex A73, A75, and A76 steadily iterated on performance while maintaining excellent energy efficiency. Qualcomm, and then Samsung decided licensing ARM’s cores would be easier than trying to outdo them. Apple remained a notable rival, but their core designs were not available outside a closed-off ecosystem. By the time Cortex A78 came around, ARM had no real competition.

ARM’s Cortex A710 continues that dominance. It takes A78’s successful formula and tweaks it to improve performance and efficiency. Efficiency is especially prioritized, with the core seeing cuts in some areas as ARM tries to get more done with less power. A710 claims to provide a 30% uplift in power efficiency or a 10% performance increase within a fixed power envelope when compared to a A78 core with half as much L3 cache. Alongside these improvements, A710 gains Armv9-A and SVE support.
