ARM has been showing off its new Arm Cortex-A77 CPU core and Mali-G77 graphics part, designed for premium smartphones slated for launch next year.

The assembled throngs at Computex 2019 in Taipei got to see the new Cortex-A77 CPU which ARM claims delivers advanced ML and AR/VR experiences thanks to a 20 percent 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 outfit said.

The Arm Mali-G77 GPU uses Valhall architecture delivering a nearly 40 per cent performance improvement over the previous Mali-G76 in devices today, the company claimed. Mali-G77 boasts key microarchitecture enhancements including engine, texture pipes, and load store caches, which achieve 30 percent better energy efficiency and 30 percent more performance density, ARM said.

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

Arm spruced up its ML processor since Project Trillium was announced last year, including increasing energy efficiency by more than 2x up to 5 TOPs/W, improving memory compression techniques up to 3x, and scaling to peak next-generation performance up to eight cores for up to 32 TOP/s. Project Trillium is a heterogeneous ML compute platform which includes the Arm ML processor and its open-source Arm NN software framework, which is now shipping in more than 250 million Android devices, the vendor said.
