Arm Announces Cortex-X4 CPU, Immortalis-G720 GPU
Following the launch of a comprehensive computational solution (TCS22, Total Compute Solutions 2022) that incorporated assets such as Cortex-X3 CPU and Immortalis GPU, Arm proclaimed at the Computex 2023 pre-show event the unveiling of a novel 2023 comprehensive computational solution, heralding the Cortex-X4 CPU, and updating the Cortex-A720 CPU, Cortex-A520 CPU, and Immortalis-G720 GPU, along with the Mali-G720 and Mali-G620 GPUs.
This update includes the Cortex-X4 CPU designed with the TSMC N3E process, boasting a 15% performance improvement and a 40% power reduction compared to its predecessor, the Cortex-X3 CPU. These enhancements lead to higher computational efficiency, better power sustainability, faster application launch times, and accelerated development of artificial intelligence and machine learning applications on the device end, all while only increasing the occupied area by a modest 10%.
The concurrently launched Cortex-A720 CPU and Cortex-A520 CPU will function as the designs for the big-core and little-core configurations of mainstream processors. The Cortex-A520 CPU offers an approximately 20% performance boost over its previous generation and can handle the computational demands of AAA-grade games.
The updated product lineup further adopts a 64-bit computational design and an Armv9 instruction set, supporting Arm memory tagging extensions, thereby rectifying most potential memory vulnerability issues prevalent in software.
As for the concurrently launched Immortalis-G720 GPU, it is crafted using the 5th-generation GPU architecture, reducing memory bandwidth occupancy issues. It promises a performance and power boost of 15% and a system-level execution performance increase of 40%. Even when employed with the same configuration as the previously launched Immortalis-G715 GPU, the occupied area only increases by 2%.
Arm touts that the Immortalis-G720 GPU can achieve higher gaming computational performance and 3D application performance on mobile devices. Additionally, it introduces Deferred Vertex Shading (DVS), which enhances the efficiency of graphics and complex workload operations and further expands GPU core quantity and visual performance.
The new Mali-G720 and Mali-G620 GPUs will serve as the design for the new big-core and little-core configurations. They can support higher display performance and more power-efficient application performances, thereby promoting computational and machine-learning capabilities on mobile devices.
In concert with the launch of the 2023 comprehensive computational solution, Arm also simultaneously introduced CoreLink CI-700, NI-700, and MMU-700, designed to meet connectivity demands. MediaTek is slated to be the first to adopt this solution for its next-generation flagship processor.
Despite recent market views suggesting that the mobile device market’s expansion capability has reached saturation, Arm contends that with mobile device app revenues reaching up to $43.1 billion, and gaming revenues on mobile devices reaching a scale of $92.2 billion, the future mobile device market still holds substantial growth potential. As a result, they are committed to persistently promoting mobile computing performance upgrades.
At the Computex 2023 pre-show event, Arm foreshadowed its ongoing commitment to promote the ‘Blackhawk’ CPU design and the ‘Krake’ GPU design. These advancements aim to push device-side computational performance to new heights and will be incorporated into the 2023 comprehensive computational solution design.
Entities, including Google, Asus, Honor, MediaTek, OPPO, Samsung, Vivo, Xiaomi, Tencent, and Unity, have all declared their intent to deepen their collaboration with Arm’s newly launched product lineup. Intel emphasized that its 18A manufacturing process technology can also be utilized for Arm’s newly launched product lineup.
