Third-Generation, High-Performance CPU Based on DynamIQ Technology
Designed for devices undertaking complex compute tasks, from edge to cloud for next-generation experiences. Cortex-A77 enables intelligent 5G compute, with performance gains on previous generations across all form factors from smartphones to laptops. It maintains Arm’s industry-leading efficiency with a next-generation device architecture that drives the rapid deployment of various applications enabled by 5G.
Features and Benefits
Improves IPC performance over previous generations by 20% for complex compute tasks on all mobile form factors.
With 5G devices already available, the rise of always-on, always-connected devices is set to increase as 5G rolls out. Cortex-A77 supports 5G and its mobile use cases, as well as always-connected laptops.
Users are demanding devices with longer battery life and consistently high performance, all in a thinner form factor. Microarchitecture updates to Cortex-A77 take advantage of DynamIQ efficient cores to improve user experiences.
