Mediatek Dimensity 9400e vs Mediatek Dimensity 9400+

Mediatek Dimensity 9400e

The MediaTek Dimensity 9400e is a fast mid-range SoC for smartphones and tablets based on Android.

The CPU no longer uses classic energy-saving cores, but two clusters of large cores. Although there is no ARM Cortex-X925 as in the Dimensity 9400, there are four ARM Cortex-X4 with up to 3.4 GHz and four ARM Cortex-A720 with up to 2 GHz.rgänger the level 3 and SLC cache, which now holds 22 MB (12 MB L3 + 10 MB system cache).

The integrated ARM Immortalis-G720 with 12 cores is responsible for graphics calculations.

The SoC is manufactured using the 4nm nanometer process at TSMC (third generation).

Mediatek Dimensity 9400+

The Mediatek Dimensity 9400 Plus is a higher-end octa-core SoC for Android tablets and smartphones that was launched on April 10, 2025. As such, it is said to feature one super-powerful Cortex-X925 core (up to 3.73 GHz), three Cortex-X4 cores (up to 3.3 GHz) and four efficient Cortex-A720 cores (up to 2.4 GHz) along with the dedicated 890 NPU and Immortalis-G925 MC12 iGPU. The older Dimensity 9400 features the same key components, their lower clock speeds being the differentiating factor.

A chip for flagship 2025 and 2026 products, the Dimensity comes with powerful navigation and networking capabilities, including Wi-Fi 7 and Bluetooth 6 and other nice features such as support for three displays. It is built with TSMC's N3E process.

Performance

Given the clock speed improvement over the Dimensity 9400, its Geekbench multi-thread performance scores should be slightly higher than those of Apple's M1 and A18 Pro as well as Qualcomm's Snapdragon 8 Elite.

Long-term performance sustainability will depend greatly on how sound heat dissipation is in a particular tablet or smartphone.

Power consumption

Its short-term power consumption is set to be very high at way over 10 W.
