Cortex-A75

The Arm Cortex-A75 processor is Arm's latest and highest-performance application CPU delivering ground-breaking performance and market-leading power efficiency across a wide range of applications. 

Information on Cortex-A75.

Getting Started

Performance from edge to cloud

The Arm Cortex-A75 CPU is built on DynamIQ technology, enabling new levels of scalability and responsiveness for your advanced use cases. 

The processor is broadly applicable from cloud to edge, providing improvements in performance, efficiency, and architecture over its predecessors, the Cortex-A72 and Cortex-A73 processors. With significantly improved integer performance, and substantial enhancements in floating point and memory workloads performance, the Cortex-A75 processor is the most powerful Cortex-A processor to date.

This additional compute capability, combined with improvements for machine learning and other advanced use cases, will enable demanding applications to run more smoothly and provide a new baseline for even more complex workloads to be developed.
