Mediatek Dimensity 9400+ vs Mediatek Dimensity 9400e

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.

Mediatek Dimensity 9400e

Der MediaTek Dimensity 9400e ist ein schneller Mittelklasse-SoC für Smartphones und Tablets, die auf Android basieren.

Die CPU setzt keine klassischen Energiespar-Kerne mehr ein, sondern auf zwei Cluster von großen Kernen. Es gibt zwar keinen ARM Cortex-X925 wie im Dimensity 9400, aber vier ARM Cortex-X4 mit bis zu 3,4 GHz und vier ARM Cortex-A720 mit bis zu 2 GHz.rgänger den Level-3- und SLC-Cache, welcher nun 22 MB fasst (12 MB L3 + 10 MB System Cache).

Die integrierte ARM Immortalis-G720 mit 12 Kernen ist für die Grafikberechnungen zuständig. 

Das SoC wird im 4nm-Nanometer-Verfahren bei TSMC (dritte Generation) gefertigt.
