Arm Announces New Platform TSC23 for Mobile Computing
At Computex 2023, Arm revealed its new platform for mobile computing—the TSC23. This system-on-a-chip contains the powerful Armv9 Cortex-X4 CPU core, the balanced Cortex-A720 cores, and the Immortalis-G720 GPU. The company also announced slightly less powerful CPUs and GPUs for more affordable devices.
The DSU-120 Compute Cluster
The eight-core cluster, which ARM calls the DSU-120, replaces the previous generation DSU-110 cluster used in the popular Snapdragon 8 Gen 2 SoC. The cluster has two Cortex-X4 high-performance cores, which handle the most demanding tasks. They deliver 15% more speed while using 40% less power than the previous-generation Cortex-X3 chip. The four Cortex-A720 cores are for balancing energy use and performance and feature 20% more efficiency than the A715 cores. Finally, two Cortex-A520 cores round out the cluster and are for performing tasks that require minimal power. Arm says this is the most performant high-efficiency core ever, with 22% more power efficiency over the outgoing A515 core.
Immortalis-G720 GPU
Arm also revealed a powerful new GPU architecture for mobile devices called the Immortalis-G720. The company says it will offer 15% more performance than the previous generation and 40% less memory bandwidth usage. It should be a powerful upgrade to last year’s Immortalis-G715, which was the company’s first to offer hardware acceleration for ray tracing.
Designed for High-End Flagships
The DSU-120 compute cluster paired with the Immortalis-G720 GPU form the center of the TSC23, which replaces the TSC22 in Arm’s lineup. While the company didn’t reveal which phones or chipmakers will use its new hardware, it made clear that this platform is designed for high-end flagships, such as the Samsung Galaxy 23 Ultra. Logically, because Qualcomm uses the Arm Cortex-X3 in its Snapdragon 8 Gen 2, Arm’s new cores could be the groundwork for the next-generation Qualcomm chip (ostensibly the 8 Gen 3). We expect to learn more from Qualcomm about its 2024 mobile processor as soon as November, though Qualcomm hasn’t yet announced a commitment to Arm’s cores.
Mali-G720 and Mali-G620 GPUs
The Mali-G720 and Mali-G620 GPUs, which Arm also announced today, are designed to bring premium GPU capabilities and features to a wider market. These will likely be used to push the gaming capabilities of affordable flagships such as the OnePlus 11, but we’ll have to wait and see which companies add these GPUs to their systems-on-a-chip.
Better High-Geometry Games and Boosted AI Functionality
In terms of actual benefits, Arm says future smartphone buyers can expect better high-geometry games, improved in-game lighting, more realistic 3D animations, and boosted AI functionality, though these will all rely on chipmakers, device makers, and developers to put fully to use.
Conclusion
Arm’s TSC23 is a significant development in the mobile computing industry, offering top-of-the-line CPU and GPU capabilities to high-end flagships. The DSU-120 compute cluster and Immortalis-G720 GPU are poised to significantly enhance mobile gaming, 3D animation, and AI performance. However, it remains to be seen which phones and chipmakers will adopt Arm’s new hardware.
