Power, consumption: why the new ARM chips will wreak havoc

At Computex 2023, ARM unveiled its new CPU and GPU designs. With them comes the promise of significantly improved performance on smartphones… but also that of consumption, as often revised downwards.

Kick-off at ARM for the 4e generation of Cortex CPU cores, but also of the 5e generation of GPU cores from the British mobile architecture designer. These two new “products” are designed to usher in a new era of smartphones that will hit the market in 2024, presumably.

During his speech, Rene Haas, CEO of ARM, therefore lifted the veil on the new Cortex-X4 CPU cores. The latter will soon take over from the Cortex-X3, which is currently found on all high-end chips that are based on the ARM architecture. We learn in particular that these new cores, which are based on TSMC’s 3 nm engraving process (N3E), will be able to develop 15% more performance than the previous generation, while placing an even greater emphasis on AI and machine learning.

These new cores will also be 40% more energy efficient than the Cortex-X3s they replace, which should lead to a further improvement in battery life for smartphones equipped with them, while reducing their heating.

On the GPU front, ARM is also announcing its Immortalis-G720. This new graphic part will take the place of the current Immortalis-G715, which can be found for example at OPPO and vivo through a partnership with MediaTek. The G720, based on the 5e generation of ARM’s GPU architecture, for its part, was designed with the objective of restoring on mobile a graphical experience approaching that of home consoles. To do this, ARM explains in particular that it has focused on supporting high-geometry games and other real-time 3D applications.

What is Arm Total Compute Solutions?

At the same time, ARM continues to deploy a new strategy aimed at offering more flexibility to its customers and to the players to which it provides its licenses. Also on the occasion of Computex 2023, the firm therefore announced a new platform intended for mobile computing. Called ARM Total Compute Solutions 2023 (TCS23), the latter aims to offer ARM partners a bundled formula with several of its products and services.

The idea? Simplify the life of companies that manufacture SoCs based on the ARM architecture (and who design their own computing subsystems, notes TechCrunch) by delivering to them turnkey the intellectual property elements they need, such as the Immortalis GPU, Armv9 processors and software improvements. As a reminder, it is under the aegis of the Armv9 that the Cortex-X4, Cortex-A720 and Cortex-A520 cores are available.
