Computex 2017: ARM’s New Cortex A75 and Cortex A55 Aim to Power the Machine-Learning Tech

At the Computex 2017 event in Taipei, ARM, the SoftBank-owned company who designs a chipset architecture has announced the Cortex A75 and Cortex A55 CPUs along with an upgraded Mali-G72 GPU. For the uninitiated, the ARM cores are used to build the Qualcomm’s Snapdragon SoC’s, Samsung’s Exynos chipsets, and even Apple’s A chipset lineup.

ARM says that the newly announced CPU’s are powerful than the previous Cortex A73 and Cortex A53 chips. While the Cortex A75 is used in high-end phones, the Cortex A55 is touted to have the highest power efficiency in any mid-range chipset. The Mali-G72 GPU is said to have 25 percent performance improvement compared to the Mali-G71.

Besides the regular power and efficiency improvements, the highlight of both the CPUs is that they are designed to make up the artificial intelligence and machine learning technologies. The Cortex A75 and Cortex A55 chips are the first Dynamiq CPUs from the company. If you’re wondering what Dynamiq CPU is- here’s the answer: The Dynamiq branding is chosen to describe a flexible set of design options for chip makers such as the Qualcomm.

With the help of Dynamiq technology, chip makers such as Qualcomm will get the access to arrange the cores in a flexible manner. Furthermore, it allows the manufacturers to embed eight cores into a single cluster which will deliver better performance.

ARM explains this as follows- A seven Cortex A55 cores and one big-clustered A75 core. This, in turn, will boost the overall performance, battery life, and becomes cost efficient as well. ARM says “50x improvement in AI performance over the next three to five years thanks to better architecture, micro-architecture, and software optimisations.”
