Mediatek Dimensity 9400 vs Mediatek Dimensity 9400+

Mediatek Dimensity 9400

The Mediatek Dimensity 9400 is the Taiwanese company's latest flagship SoC for premium Android phones and tablets, as of Nov 2024. It sports 1 Cortex-X925 core running at up to 3.62 GHz along with 3 Cortex-X4 cores (up to 3.25 GHz) and 4 Cortex-A720 cores (up to 2 GHz). The Immortalis-G925 MP12 serves as the integrated GPU and there is also the MediaTek 890 8th generation NPU with one "performance" core and one "flexible" core. Naturally, 5G, Wi-Fi 7, Bluetooth and satellite navigation are included, too.

Architecture and Features

The CPU is based on the ARM v9.2 architecture to a certain degree. There are no "little" cores here, much like it was with the Dimensity 9300 (4x Cortex-X4 and 4x Cortex-A720 cores). This is an approach that's vastly different to what all other ARM chipmakers do.

The manufacturer has given a boost to the level 3 and SLC caches compared to the previous-gen chip, which now have a combined capacity of 22 MB (12 MB L3 + 10 MB system cache). LPDDR5x RAM as fast as 10667 MT/s is supported; there are other cool features such as the 12-transistor L1 cache system and "up to 1.5 km" Bluetooth coverage.

Performance

The chip delivers ~9000 Geekbench 6.3 Multi points, making it a few percentage points faster than the Apple A18 Pro and about 20% faster than the Dimensity 9300.

Graphics

The ARM-developed Immortalis-G925 GPU (the 12-core variety) comes with hardware ray tracing, Accuracy Super Resolution and more. It's ready to power three-display folding phones as well as drive "WQHD+" resolution displays at up to 180 Hz, and it HW-decodes the codecs that matter most - AVC, HEVC, VP9, AV1.

The ~2700 3DMark Steel Nomad Light points that it delivers make it almost as fast as the Qualcomm Adreno 830.

Power consumption

Its peak power consumption is reportedly very high at well over 10 W. Gaming phones with advanced cooling solution are set to get much better performance (especially sustained performance) out of the SoC than regular thin models.

The Dimensity is built with TSMC's N3E process which is still state-of-the-art as of late 2024.

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.
