MediaTek Unveils Dimensity 9400 Its Flagship Mobile SoC Featuring Second-Gen “All-Big-Core” CPU Architecture And Agentic AI-ready NPU.

MediaTek introduced its new flagship mobile System-on-Chip (SoC)i Maximum 9400marking a huge leap in mobile computing power. It is built upon TSMC’s second generation 3 nm processthis chipset promises major improvements in both performance and power efficiency. Compared to its predecessor, Dimensity 9300this new processor up to 40% more energy.

Second generation “All-Big-Core” CPU design.

At the heart of Dimensity 9400 2nd generation MediaTek “All-Big-Core” Architecture.which infuses new energy Arm Cortex-X925 CPU. Closed on 3.62 GHzthe Cortex-X925 offers 35% faster single-core performance again 28% faster multicore performance than last year’s model, the Dimensity 9300.

SoCs 8-core CPU includes one Cortex-X925 core (very large spine)three Cortex-X4 cores (large cores)and four Cortex-A720 cores are active. While the Seven Friends configuration mirrors last year’s, MediaTek has made significant improvements to the app. cache memoryincreasing L3 cache by 50% (from 8MB to 12MB) and doubling L2 cache, further improving processing efficiency. Combined with LPDDR5x memory running at 10.7 Gbpsthis setup ensures that the Dimensity 9400 can better handle computing-hungry tasks, including high-end gaming and intensive applications.

By doubling down on the “All-Big-Core” approach, Mediatek aims to maintain a competitive edge using aggressive performance.

Arm Immortalis G925 GPU: Improves Mobile Gaming

The Dimensity 9400 also introduces the Arm Immortalis G925 GPUwhich brings 12 cores breaking force. MediaTek says this GPU can deliver 40% faster radiation tracking and of course 44% more energy efficient than the previous one.

Ray tracing is something way to give you used to improve the accuracy of computer graphics. It imitation how light interacts with surfaces and objects to create reflections, shadows, and other visual effects. However, the GPU must be extremely powerful to maintain high frame rates in complex 3D scenes with millions of triangles. With this new GPUMediatek claims PC-grade raytracing abilities. Well, we will have to see how it works in real life to verify the claim.

NPU 890: Powering Agent AI and On-Device LoRA Training

One of the outstanding features of the Dimensity 9400 is the NPU 890MediaTek 8th generation Neural Processing Unit (NPU)designed to accelerate AI-driven applications. This NPU delivers 80% more performance. in management Gen-AI teaches major linguistic models (LLMs)while also contributing 35% better energy efficiency more than the previous generation (APU790).

What sets the NPU 890 apart is its support capability AI Agenta type of AI that can operate independently, make decisions, and achieve goals without human supervision. This is a departure from traditional production AI, which focuses on the creation of content from information and does not work automatically.

Additionally, the NPU can manage On-device LoRA (Low-Rank Adaptation) training, an effective way to fine-tune large-scale linguistic models (LLMs), which helps to improve the performance of Gen-AI on the device.

According to Finnbar Moynihan, GM/VP of Corporate Marketing, MediaTek, the NPU 890 is capable of high resolution video production and make a The first multi-modal AI at the edge (on the device) by 50 tokens per second.
