The new Arm Cortex-A77 CPU core and Mali-G77 graphics part, designed for premium smartphones slated for launch next year, have been debuted at the ongoing Computex 2019 in Taipei.

Every new smartphone experience begins with more hardware performance and features that enable developers to unleash further software innovation. For them, the CPU is more critical than ever as it handles general-compute tasks, as well as much of the device's machine learning (ML) compute which must scale beyond today's limits, according to Arm.

The new Arm Cortex-A77 CPU delivers advanced ML and AR/VR experiences thanks to a 20% IPC performance improvement over Cortex-A76 devices, the company noted. The past two generations of Cortex-A7x series processors (Cortex-A76 and Cortex-A77) have increased overall ML performance by 35x. The new Cortex-A77 CPU underpins Arm's continued push for performance and efficiency within smartphone power budgets with performance comparable to today's mainstream notebooks.

The Arm Mali-G77 GPU meets that challenge with the brand-new Valhall architecture delivering a nearly 40% performance improvement over the previous Mali-G76 in devices today, the company claimed. Mali-G77 also boasts key microarchitecture enhancements including engine, texture pipes, and load store caches, which achieve 30% better energy efficiency and 30% more performance density.

Besides, Mali-G77 brings a 60% improvement to ML performance, which significantly boosts inference and neural net (NN) performance for advanced on-device intelligence, Arm said.
