Key Takeaways
1. The Dimensity 7400 features a slight CPU speed increase to 2.6GHz, but overall performance changes from the 7300 are minimal.
2. Both chipsets support the same memory, storage, and connectivity options, offering identical user experiences in networking.
3. Camera capabilities are largely unchanged, with the Dimensity 7400 introducing only minor enhancements like hardware-assisted autofocus.
4. The graphics performance remains the same, as both models use the same Arm Mali-G615 MC2 GPU, leading to similar gaming experiences.
5. The rebranding from 7300 to 7400 seems driven by marketing rather than significant technological advancements.
MediaTek has introduced its latest chip, the Dimensity 7400, which replaces the Dimensity 7300 as the new mid-range option. If you’re curious about whether this is a significant upgrade or just a minor tweak, you’re not alone in that thought.
MediaTek often rolls out small updates in its mid-range series, and the changes from one version to the next aren’t always obvious at first glance. So, what has changed this time? Does the Dimensity 7400 bring anything noteworthy compared to the 7300? Let’s look closely.
Core Design
When it comes to the Dimensity 7400 and 7300, they are remarkably alike. Both feature an octa-core CPU, which includes four Cortex-A78 cores and four Cortex-A55 cores. The main distinction lies in the A78 cores of the 7400, which can now reach speeds of 2.6GHz, a slight increase of 100MHz from the 7300’s 2.5GHz. This boost won’t make a significant difference in everyday use, unless you’re focused on minute benchmarking.
Memory and storage capabilities are the same for both chips, as they support LPDDR4x and LPDDR5 RAM at speeds up to 6400Mbps, in addition to being compatible with UFS 3.1 storage.
Connectivity Features
The Dimensity 7400 and 7300 share the same cellular technology support, which includes SA and NSA 5G, as well as 3CC carrier aggregation, with peak download speeds of 3.27 Gbps. Both also feature Wi-Fi 6E and Bluetooth 5.4.
In simpler terms, if you’re using a device with either of these processors, your network experience will be identical.
Imaging Capabilities
The camera functionalities are also quite similar. Both chipsets include the Imagiq 950 ISP, offering 12-bit HDR and support for 200MP sensors, and they can record 4K HDR video at 30fps. The Dimensity 7400 introduces “hardware-assisted autofocus” (AF) as an added feature, but this isn’t a major change since the 7300 already provides all-pixel AF and dual video capture simultaneously.
Unless there are hidden improvements, users likely won’t notice significant changes in photography or videography quality.
Graphics and AI
For graphics, MediaTek has retained the Arm Mali-G615 MC2 GPU on the Dimensity 7400, the same as the previous model. The maximum display refresh rates are unchanged: WFHD+ at 120Hz or Full HD+ at 144Hz—no differences here either.
Since both chips have identical GPUs, you can anticipate similar gaming experiences on both.
AI continues to be a key focus in 2025, largely due to NPUs that handle the processing, making AI tasks more efficient on smartphones. With the growing number of AI features, it would have been reasonable for MediaTek to enhance AI capabilities in the Dimensity 7400. Unfortunately, there’s nothing new compared to the 7300.
Both processors feature the same NPU 655, meaning AI functions—like scene recognition in photos or background noise reduction in calls—will operate just like they did in the previous model.
Why the Dimensity 7400?
Considering how alike these chips are, one might wonder why MediaTek chose to rebrand the Dimensity 7300 as the 7400. The 100MHz CPU increase is hardly noteworthy, and there’s no substantial upgrade in GPU, connectivity, storage, or AI capabilities.
The most likely reason for this rebranding seems to be marketing. A new number sounds appealing, particularly for smartphone manufacturers wanting to refresh their product range without making significant hardware changes. It allows MediaTek to keep its branding current without launching any real upgrade.
Conclusion
If you were hoping for significant advancements from MediaTek’s latest mid-range chipset, it might be best to lower your expectations. The Dimensity 7400 is, in essence, a rehashed Dimensity 7300 with just a minor CPU clock increase and a few barely noticeable changes.
