Mediatek officially announces Dimensity 9400 With 35 Percent Faster Performance, Improved NPU

MediaTek Dimensity 9400 SoC, the latest flagship tier smartphone processor, was launched on Wednesday. The company had earlier said that the mobile platform would be introduced in October and shared a few details. Now more details are given about the features and capabilities of this processor. The tech giant says the new system-on-chip (SoC) offers 35 percent faster performance on a single core than its predecessor. MediaTek Dimensity 9400 SoC competes with Snapdragon 8 Gen 3 chipset and Apple A18 series chipset.

In a press release, the chip maker introduced a new mobile platform. The MediaTek Dimensity 9400 chipset is a fourth-generation flagship processor, built on Arm’s v9.2 CPU architecture with a dedicated GPU and Neural Processing Unit (NPU) architecture. The highlight is that it is built on TSMC’s second-generation 3nm fabrication process.

Continuing the tradition of all-core design, it has one Cortex-X925 core with a maximum clock speed of 3.62GHz, ten Cortex-X4 cores, and four Cortex-A720 cores. The company says this CPU architecture offers 35 percent faster single-core performance and 28 percent faster multi-core performance compared to the Dimensity 9300 SoC. Its power efficiency is also 40% higher than its predecessor.

MediaTek Dimensity 9400 chipset also integrates the company’s eighth-generation NPU and provides developer support for on-device LoRA training, on-device video generation capability, and artificial intelligence (AI). The company says this SoC can deliver up to 80 percent faster performance in Large Language Model (LLM) instantiation, while also maintaining 35 percent higher power efficiency than the previous generation.

Talking about the GPU, the 12-core Arm Immortalis-G925 has been integrated into the mobile platform, offering 40 percent faster ray tracing performance than its predecessor. In addition, MediaTek says it offers a 41 percent higher performance improvement and 44 percent power savings compared to the Dimensity 9300. The chipset also supports HyperEngine technology.

Additionally, MediaTek Dimensity 9400 has Imagiq 1090 for on-device image processing. There are also some minor improvements like HDR video recording with full zoom range, better performance in capturing moving objects, and significantly lower power consumption when recording 4K60 fps videos than before.
