MediaTek Dimensity 7400 vs 7300: What’s New and What’s Not?

MediaTek has unveiled its new mid-range chipset, the Dimensity 7400, taking over from the Dimensity 7300. But is it truly an upgrade or just a minor refresh? MediaTek is known for iterative updates in its mid-range lineup, often making it difficult to spot major differences at first glance. So, what exactly has changed this time? Let’s break it down.

CPU Performance: A Minor Clock Speed Bump

The Dimensity 7400 and 7300 are almost identical in CPU configuration. Both feature an octa-core setup with four Cortex-A78 cores and four Cortex-A55 cores. The only difference? The A78 cores in the Dimensity 7400 now reach a clock speed of 2.6GHz, up from 2.5GHz in the 7300. This 100MHz increase is unlikely to make a noticeable impact on real-world performance unless you're running benchmark tests.

Memory and Storage: No Changes Here

Both chipsets support LPDDR4x and LPDDR5 RAM, with speeds reaching up to 6400Mbps. Storage support also remains the same, with UFS 3.1 compatibility. If you were hoping for faster memory or storage access, you’ll be disappointed.

Connectivity: Identical Networking Features

There are no changes in the connectivity department either. Both the Dimensity 7400 and 7300 support:

• SA and NSA 5G
• 3CC carrier aggregation
• Peak downlink speeds of 3.27 Gbps
• Wi-Fi 6E
• Bluetooth 5.4

In short, your network experience will be identical whether you choose a phone with the Dimensity 7400 or the 7300.

Camera and Imaging: Minor Autofocus Addition

The camera ISP remains unchanged, with both featuring the Imagiq 950 ISP, which supports:

• 12-bit HDR
• 200MP sensors
• 4K HDR video recording at 30fps

The only addition on the Dimensity 7400 is “hardware-assisted autofocus” (AF). However, since the Dimensity 7300 already supports all-pixel AF and dual video recording, this change is unlikely to bring any meaningful improvements in real-world photography or videography.

Graphics and Display: No Upgrades

Gaming enthusiasts will find no improvements in GPU performance. Both chips utilize the same Arm Mali-G615 MC2 GPU. Maximum supported display refresh rates also remain unchanged at WFHD+ 120Hz or Full HD+ 144Hz. This means gaming performance and overall visual experience will be identical on both chipsets.

AI Processing: No New Developments

Artificial Intelligence (AI) is a major trend in 2025, but MediaTek hasn’t introduced any AI enhancements with the Dimensity 7400. Both chips continue to feature the NPU 655, handling AI-related tasks like scene recognition in photography and noise cancellation in calls. This means AI performance remains the same between the two processors.

Why Did MediaTek Release the Dimensity 7400?

Given how similar these two chipsets are, it raises the question: why did MediaTek even bother renaming the Dimensity 7300? The only plausible explanation is marketing. Smartphone manufacturers benefit from having a new chipset name in their spec sheets, making their latest models appear more updated, even when the actual hardware hasn’t changed significantly.

Final Verdict: Is the Dimensity 7400 an Upgrade?

If you were expecting the Dimensity 7400 to bring significant performance improvements, it’s time to lower your expectations. This chipset is essentially a repackaged Dimensity 7300 with a small CPU clock speed increase and a minor autofocus enhancement.

When choosing between a phone powered by the Dimensity 7400 and one with the 7300, your decision should be based on other factors—such as battery life, camera quality, and software optimization—since the chipset itself won’t make a significant difference in daily usage.
