ARM, the British chip designer company, today unveiled its latest Cortex-A72 architecture that it expects to power the mobile devices of next year. The suite of IP announced today includes the Cortex-A72 CPU architecture and the Mali-T880 GPU, together with the CoreLink CCI-500 interconnects.
The ARM Cortex A-72 is claimed to be the highest performing mobile CPU to date and brings up to 3.5 times the performance of Cortex-A15 CPU with up to 75% less energy requirement for workloads. In comparison to the current Cortex-A57, the Cortex-A72 is roughly twice as powerful. The Cortex-A72 will be fabricated in a 16nm FinFET process and is scalable to higher frequencies for use in high-end tablets and also other devices such as smart HDTVs. For further performance and energy efficiency, the Cortex-A72 can be combined with a Cortex-A53 CPU in ARM’s big.LITTLE configuration.
The new Mali-T880 GPU is also as impressive as the Cortex-A72 CPU. ARM claims the new GPU can deliver up to 1.8 times higher performance compared to the Mali T760 GPU that is shipping in popular devices such as the Exynos Galaxy Note 4 today, bringing true console-quality gaming experience to mobile devices in 2016. ARM has managed to improve the energy efficiency with the new GPU, with a claimed 40 per cent reduction in energy consumption. The Mali-T880 will be able to support 4K120fps with its eight cores and combination of the new Mali-V550 video processor and Mali-DP550 display processor. It can handle hardware HEVC decoding and encoding on a single core, helping reduce power consumption and maximize the battery life.
ARM’s new CoreLink CCI-500 interconnect offers double the peak memory system bandwidth and brings up to 40% improvement in processor memory performance over the previous generation CCI-400 interconnect. It is also optimized for the big.LITTLE heterogeneous computing architecture and can enable implementations up to 2.5GHz on mobile devices.
