The Dimensity 9400 Plus is the stronger chip on the published specifications and benchmark figures available here: it has a higher-clocked Cortex-X925 prime core, a newer listed GPU generation, and higher scores in both cited comparison datasets. The Dimensity 9400e is still a flagship-class option, but the scores are not controlled head-to-head tests, and a phone’s cooling, firmware, memory, price, and battery matter as much as the chipset when choosing a handset.
What is different between the Dimensity 9400 Plus and 9400e?
MediaTek announced the Dimensity 9400+ on April 10, 2025. Its official product page specifies an eight-core CPU with one Arm Cortex-X925 core up to 3.73 GHz, three Cortex-X4 cores, and four Cortex-A720 cores, alongside LPDDR5X memory. MediaTek’s announcement describes the platform as designed to support on-device AI and overall performance, but that company statement is not independent benchmark evidence.
The 9400e specification details below come from 91Mobiles, not a complete official MediaTek specification table. MediaTek’s surfaced 9400e infographic does not provide a full table that independently confirms those CPU and GPU details.

The clearest architectural distinction is the 9400 Plus’s Cortex-X925 prime core versus the 9400e’s listed Cortex-X4 prime core. The listed graphics generation also differs: G925 for the Plus and G720 for the 9400e. These specifications suggest an advantage for the Plus, but they do not establish how long either chip can sustain peak performance in a particular phone.

How do the benchmark scores compare?
91Mobiles reports higher results for the Dimensity 9400 Plus in its comparison. These are that site’s reported figures, not universal chip scores; the available source does not give enough methodological detail to verify matched phone hardware, cooling, software, or test conditions.
| Benchmark and source | Dimensity 9400 Plus | Dimensity 9400e |
|---|---|---|
| AnTuTu, 91Mobiles | 2,821,319 | 2,125,733 |
| Geekbench single-core, 91Mobiles | 2,675 | 2,219 |
| Geekbench multi-core, 91Mobiles | 8,463 | 7,308 |
NanoReview publishes another comparison using AnTuTu 11: 2,874,956 for the 9400 Plus from 171 samples, and 2,518,801 for the 9400e from 46 samples. Those are sample-based aggregates, not a matched test run. The benchmark version and sample counts differ from the 91Mobiles figures, so the two datasets should not be merged or treated as one controlled comparison. Both sources show the Plus ahead in their reported results, but neither establishes a guaranteed performance gap for every phone.

Which chip should you choose in a phone?
Choose a 9400 Plus phone if performance headroom is your priority
The 9400 Plus has the stronger listed CPU and GPU specifications, and it leads in both cited benchmark comparisons. That makes it the more compelling starting point if you are comparing otherwise similar phones and value high peak performance. A chipset result alone cannot tell you whether a phone will deliver better sustained gaming, cooler operation, or longer battery life.

Consider a 9400e phone when the handset is the better overall fit
The 9400e’s reported benchmark scores are lower, but the phone may still be the better purchase if it offers a more suitable price, display, battery, software support, cooling design, or regional availability. These handset-level trade-offs are not established by chipset comparison pages and need to be checked against the specific models you can buy.
