Arm has unveiled a new generation of Armv9 CPUs and GPUs that will power future Qualcomm, MediaTek and Exynos chipsets for smartphones in 2023. Let’s start with the most powerful – the Cortex-X3 core, which will become 22% more powerful than the Cortex-X2 familiar to us from Snapdragon 8/8+ Gen1 and Dimensity 9000/9000+. Curiously, Arm hasn’t made any power-efficiency claims, which is cause for concern. The company limited itself to demonstrating an abstract graph, according to which the Cortex-X3 shows improved performance at a slightly higher power consumption.

The second novelty of the day was the productive Cortex-A715 core, the main feature of which was the final transition to 64-bit instructions, without 32-bit support. But the increase in computing power, alas, is very modest: only + 5% compared to the Cortex-A710. On the other hand, the energy efficiency of the solution soared by 20%, which will clearly help smartphones save battery. However, according to Arm, the Cortex-A715 is capable of hitting the same performance bar as the Cortex-X1 two years ago.

At the same time, a refresh version of the energy-efficient Cortex-A510 cores was also released, which actually remained the same, but with a 5% reduction in power consumption. In addition, 64-bit cores can be configured by the manufacturer for 32-bit ones (due to the refusal to support 32-bit in the Cortex-A715), which can be useful in IoT systems and outdated software.

Finally, new graphics cores were introduced, the most prominent of which was the Immortalis-G715. Its unique feature is that it is the first Arm core with hardware support for ray tracing. It is claimed that in ray tracing tasks it is 300% more efficient than “rays” implemented in software. In general, the Immortalis-G715 is 15% superior to the Mali-G710 from Dimensity 9000, both in terms of performance and energy efficiency. At the same time, a twofold increase in machine learning tasks is mentioned. The company with him presented the Mali-G715 graphics core without the Immortalis prefix – the same thing, but without ray tracing and cheaper.

The junior GPU Mali-G615 completes the parade of new products, offering all the chips and developments from the G715, but with a smaller number of cores (up to 6 versus 7-10 for the G715). All cores introduced today will be used in next-generation mobile chipsets, including both flagship (Snapdragon 8 Gen 2, Exynos 2300 and Dimensity 9000/9000+ successor) and more affordable ones.
