Just a few days ahead of its official unveiling, crucial information about the MediaTek Dimensity 9400’s core setup has been shared by reliable tech source Digital Chat Station (DCS). This leak uncovers the CPU and GPU configurations of the soon-to-be-released chipset.
Dimensity 9400 Specs
DCS reports that the Dimensity 9400 will include a single prime core, specifically the Cortex-X925, operating at 3.62 GHz. This marks a significant increase from the previous generation’s Cortex-X4 core, which had a speed of 3.25 GHz. Furthermore, the leak indicates that the three Cortex-X4 cores will continue to function at the same 2.80 GHz clock speed as seen in the Dimensity 9300.
Potential Core Confusion
There is a small discrepancy concerning the low-power cores. While earlier information suggested the use of newer Cortex-A725 cores, DCS indicates that the Dimensity 9400 may actually continue with the Cortex-A720 cores from the prior model. This could be an error on DCS’s part, as it’s expected that newer processors would utilize the latest CPUs. Regardless, if this information is correct, the core clock speed should remain at 2.0 GHz. On the graphics side, the leak reveals an Immortalis-G925 MC12 GPU clocked at 1.612 GHz.
Manufacturing Advances
In addition, past reports indicate that the Dimensity 9400 will move from TSMC’s 4nm node to the second generation 3nm N3E node. This updated manufacturing technique is anticipated to bring enhancements in both performance and efficiency. As a flagship SoC for 2024/2025, it’s also expected to excel at handling AI workloads.
The MediaTek Dimensity 9400 has also been confirmed to incorporate Samsung’s LPDDR5X memory, a first in the industry. This memory type is the fastest globally, achieving data transfer speeds of up to 10.7Gbps, and is said to enhance on-device AI capabilities, especially for tasks like voice-to-text conversion.
In light of these leaked specifications, here's a comparison between the Dimensity 9400 and the Dimensity 9300:
| Features/Performance | Dimensity 9300 | Dimensity 9400 (Rumored) |
|---|---|---|
| CPU Architecture | 1x Cortex-X4 core @ 3.25GHz 3x Cortex-X4 @ 2.85GHz 4x Cortex-A720 @ 2.0GHz | 1x Cortex-X925 core @ 3.62GHz 3x Cortex-X4 @ 2.85GHz 4x Cortex-A725 / A720 @ 2.0GHz |
| GPU | Immortalis-G720 | Immortalis-G925 MC12 |
| Manufacturing Process | TSMC’s third-generation 4nm process | TSMC’s second-generation 3nm process |
| Memory | LPDDR5T memory running at 9600 Mbps | LPDDR5X memory running at 10.7Gbps |
