Dimensity 7300 Max vs 7400 Ultra: Which Chipset Is Better?

There is not enough comparable evidence to name the Dimensity 7300 Max or Dimensity 7400 Ultra the clear winner. MediaTek’s published specifications cover the base Dimensity 7300 and 7400 platforms, not a complete specification sheet for these two branded variants. The base 7400’s Cortex-A78 cores are rated up to 2.6 GHz, versus up to 2.5 GHz on the base 7300; most other listed platform capabilities are shared. Benchmark figures available for the branded chips come from different device contexts, so they do not settle which one performs better in the same phone or workload.

What the official specifications say

MediaTek’s official pages describe the base Dimensity 7300 and Dimensity 7400 platforms. realme’s official product comparison uses the names Dimensity 7300 Max and Dimensity 7400 Ultra, but the available official material does not provide a comprehensive, direct specification sheet for those exact variants. Treat the table below as a comparison of the base platforms, not a guarantee that every Max or Ultra handset implements every feature identically.

What the clock difference means

The base 7400 lists a maximum Cortex-A78 clock 100 MHz higher than the base 7300. That is a specification difference, not proof of a particular real-world speed increase. Performance also depends on how a phone manages power and heat, as well as its software and memory configuration.

#1 Best Overall

AGM G3 Pro Flagship Rugged Phone, 512x384 25fps Thermal Camera, 24GB+512GB

• PROFESSIONAL THERMAL VISION | The 512x384 thermal camera combines smooth 25fps imaging with 40mK thermal sensitivity to reveal subtle heat differences during electrical checks, HVAC diagnostics, engine inspections, building maintenance and repairs. With dual temperature ranges reaching up to 550°C, G3 Pro puts a serious thermal tool directly in your phone for troubleshooting and field work
• T-MOBILE CONNECTIVITY | Designed for compatible T-Mobile service in the U.S., G3 Pro android phone supports 5G where available, 4G LTE, Dual Nano SIM and Dual Standby for flexible work, personal and travel use. Fast mobile data keeps navigation, cloud files, video calls and field apps moving, while NFC and multi-satellite positioning add useful support for payments and navigation
• FAST PERFORMANCE, SERIOUS STORAGE | The 4nm MediaTek Dimensity 7300 pairs 12GB physical RAM with up to 12GB memory expansion for responsive multitasking across maps, reports, streaming and everyday apps. 512GB built-in storage plus up to 1TB expandable space gives you room for thermal records, photos, video and offline files, while the 6.72" FHD+ 120Hz display keeps scrolling and navigation fluid
• 10000MAH POWER, FLEXIBLE CHARGING – Built for long shifts, road trips, navigation and extended days away from a charger, the 10000mAh battery delivers serious endurance while the approximately 375g body keeps G3 Pro more manageable than many extreme-battery rugged phones. Recharge with 33W USB-C PD, use 18W wireless charging, or share power through reverse charging with compatible devices
• BUILT TOUGH, LOUD AND READY OUTSIDE | IP68/IP69K protection and MIL-STD-810H durability help G3 Pro handle rain, dust, mud, drops and demanding jobsite conditions, while the powerful 116dB speaker keeps calls, alerts and navigation easier to hear in noisy surroundings. A built-in camping light, 64MP Sony main camera, 50MP front camera, OTG and 3.5mm audio add practical tools for inspections, night tasks, work records and outdoor use

Why identical platform listings do not guarantee identical phones

Both base platforms list four Cortex-A78 cores, four Cortex-A55 cores and the Mali-G615 MC2 GPU. The 7300 platform lists UFS 3.1 storage support, while the 7400 platform lists UFS 2.2 or UFS 3.1. The supported maximum does not tell you which storage type a manufacturer fitted to a particular handset. Check the exact model and regional SKU rather than inferring its configuration from the chipset name.

What the benchmark results show—and what they do not

91mobiles reports device-tested results for a Dimensity 7300 Max device and a Dimensity 7400 device. Its comparison labels the second chip “Dimensity 7400,” not “Dimensity 7400 Ultra.” The figures are therefore not an exact comparison of the two variants in this article.

These are results reported by 91mobiles for tested devices, not guaranteed scores for every phone using either chip. The source’s comparison is available at 91mobiles’ Dimensity 7300 Max vs Dimensity 7400 page.

Separately, 91mobiles’ Dimensity 7400 Ultra listing reports 1,047,842 as the highest recorded AnTuTu result in its pool of tested devices. That is a device-tested maximum, not a controlled head-to-head result against a matched Dimensity 7300 Max phone. It should not be combined with the 7300 Max result above to declare a winner. See 91mobiles’ Dimensity 7400 Ultra listing.

Why scores vary between phones

Cooling, firmware, RAM, storage, benchmark version and power settings can all affect a device’s result. Without the same test method and closely matched phone conditions for both exact variants, small differences in reported scores cannot establish which chipset is faster overall.

Which one is better for gaming?

The platform specifications alone do not establish a gaming winner: both list the same Mali-G615 MC2 GPU, and the available benchmark evidence is not a controlled comparison of the exact Max and Ultra variants. A phone’s ability to sustain performance also depends on its cooling and power limits, so a brief peak result does not tell you how it will perform through a long gaming session.

For a gaming-focused choice, compare reviews or tests of the exact handsets you can buy. Look for sustained performance and heat during longer play, not just the chipset label or a single benchmark score.

How to choose between phones using these chips

Compare the complete handset and its exact regional model. The chipset is only one part of the experience; these details can make a more practical difference to your purchase:

• Price and availability: Check current local pricing and whether the exact model is sold in your country.
• RAM and storage: Confirm installed memory capacity and whether the phone uses UFS 2.2 or UFS 3.1 storage.
• Gaming and heat: Seek sustained-load testing for the handset, including temperature or throttling observations.
• Battery and charging: Compare the phone’s battery capacity, charging support and independent endurance results.
• Display: Check the actual panel resolution and refresh rate; platform support does not specify what the phone includes.
• Cameras: Compare the fitted sensors and camera results. Support for a sensor up to 200 MP does not establish image quality.
• Software support: Check the manufacturer’s update policy for that model and market.
• Regional SKU: Verify the exact chipset, wireless bands and memory/storage configuration for the version sold where you live.

Verdict

The base Dimensity 7400 has a 100 MHz higher maximum Cortex-A78 clock than the base 7300, while both list the same CPU core arrangement and Mali-G615 MC2 GPU. That modest specification distinction does not prove a clear real-world advantage for the Dimensity 7400 Ultra over the Dimensity 7300 Max. Choose between the phones on their verified configurations, sustained performance, software support and price—not on non-matched benchmark figures.
