ARM Cortex-A35 is the first CPU in a new family of ultra-high-efficiency ARMv8-A processors designed for high-growth mobile and embedded applications. Cortex-A35 has been designed to open up greater user experiences enabled by the ARMv8-A architecture with its 64-bit capable and 32-bit computational capability and complete set of cryptography features. ARM expects the Cortex-A35 to begin shipping in production silicon from its partners by late 2016.

“Cortex-A35 is the natural successor to the compact-footprint Cortex-A7, the leading energy-efficient processor, which has powered more than a billion smartphones and tablets,” said James McNiven, general manager, CPU group. “With the introduction of the world’s most efficient 64-bit capable mobile processor, ARM and its partners will deliver the benefits of 64-bit computing to the next billion smartphone users and beyond.”

The Cortex-A35 is the most efficient Cortex-A class CPU ever designed by ARM. It takes the power profile of Cortex-A7 and its ARM big.LITTLE^™ multi-core configurability and combines it with the software maturity and 64-bit compute performance of the ARMv8-A architecture. Cortex-A35 also delivers an average of 20 percent greater performance and efficiency across a range of 32-bit mobile workloads relative to Cortex-A7 while consuming less than 90mW total power per core when operating at 1GHz in a 28nm process node. Overall, the Cortex-A35 processor is a performance-per-milliwatt leader designed to enable a complete and uncompromised 64-bit mobile user experience while maintain full compatibility with existing 32-bit applications.

ARM and its partners are building a 64-bit ecosystem that is growing rapidly, with more than 50 percent of smartphones now shipping using an SoC based on the ARMv8-A architecture. The 64-bit capable Cortex-A53 represents a large percentage of those units. The Cortex-A35 consumes about 33 percent less power per core and occupies 25 percent less silicon area, relative to the Cortex-A53.
