MediaTek today launched the Dimensity 9400, the company's new flagship smartphone chipset optimized for edge-AI applications, immersive gaming, incredible photography, and more. The Dimensity 9400, the fourth and latest in MediaTek's flagship mobile SoC lineup, offers a massive boost in performance with its second-generation All Big Core design built on Arm's v9.2 CPU architecture, combined with the most advanced GPU and NPU for extreme performance in a super power-efficient design.

The Dimensity 9400 adopts MediaTek's second-gen All Big Core design, integrating one Arm Cortex-X925 core operating over 3.62 GHz, combined with 3x Cortex-X4 and 4x Cortex-A720 cores. This design offers 35% faster single-core performance and 28% faster multi-core performance compared to MediaTek's previous generation flagship chipset, the Dimensity 9300. Built on TSMC's second-generation 3 nm process, the Dimensity 9400 is up to 40% more power-efficient than its predecessor, allowing users to enjoy longer battery life.

In addition to its two new CPU cores, Arm has announced three new GPU cores, namely the Immortalis-G925, Mali-G725 and Mali-G625. Starting from the top, the Immortalis-G925 is said to bring up to 37 percent better performance at 30 percent lower power usage compared to last year's Immortalis-G720 GPU core, whilst having two additional GPU cores in the test scenario. It's also said to bring up to 52 percent better ray tracing performance and up to 36 percent improved inference in AI/ML workloads. It's also been given a big overhaul when it comes to ray tracing—due to it being aimed towards gaming phones—and Arm claims that it can either offer up to 52 percent increased performance by reducing the accuracy in scenes with intricate objects, or 27 percent more performance with maintained accuracy.

The Immortalis-G925 supports 50 percent more shader cores and it supports configurations of up to 24 cores, compared to 16 cores for the Immortalis-G720. The Mali-G725 will be available with between six and nine cores, whereas the Mali-G625 will sport between one and five cores. The Mali-G625 is intended for smartwatches and entry-level mobile devices where a more complex GPU might not be suitable due to power draw. The Mali-G725 on the other hand is targeting upper mid-range devices and the Immortalis-G925 is aimed towards flagship devices or gaming phones as mentioned above. In related news, Arm said it's working with Epic Games to get its Unreal Engine 5 desktop renderer up and running on Android, which could lead to more complex games on mobile devices.
