On the available aggregate benchmarks, the base MediaTek Dimensity 8400 scores higher than the Snapdragon 7s Gen 4, especially in AnTuTu 11. But that is not a verified head-to-head result for the Dimensity 8400 Max: the benchmark comparison covers the base 8400, while a third-party listing uses the Max name and gives its clock speeds. The reviewed sources do not establish that Max, base 8400 and 8400-Ultra are interchangeable.
What is the difference between Dimensity 8400 and 8400 Max?
The naming needs care before comparing specifications or scores. MediaTek’s official product page identifies the chip as Dimensity 8400, without “Max.” A 91mobiles listing uses “Dimensity 8400 Max” and gives a CPU clock configuration, but the reviewed sources do not show that this variant is equivalent to the base 8400 or to Dimensity 8400-Ultra.

MediaTek’s device directory lists the POCO X7 Pro with Dimensity 8400-Ultra. That listing does not resolve whether Ultra, Max and base 8400 share the same specifications or performance. Accordingly, the benchmark figures below are for the base Dimensity 8400, not a confirmed 8400 Max.

Benchmark results: Dimensity 8400 leads in the reported comparisons
NanoReview’s comparison reports higher Dimensity 8400 results in the two fully exposed head-to-head scores below. These are aggregated submissions from different phones, not controlled tests of equivalent retail handsets. NanoReview’s page compares the base Dimensity 8400 rather than explicitly testing the 8400 Max.

| Benchmark | Snapdragon 7s Gen 4 | Dimensity 8400 | Reported sample context |
|---|---|---|---|
| AnTuTu 11 total | 1,041,898 | 1,948,428 | 35 vs 313 tests listed by NanoReview |
| Geekbench 6 single-core | 1,223 | 1,576 | 13 vs 31 tests listed by NanoReview |
| Geekbench 6 multi-core | 3,168 | Not fully exposed in the comparison | NanoReview comparison extract |
| PCMark 3.0 | 13,701 | 14,015 | Fewer than 3 tested phones vs 5 models listed by NanoReview |
NanoReview’s comparison lists those scores and sample counts; its aggregates can reflect different devices and test conditions. In particular, a higher aggregate score does not guarantee the same advantage in a specific phone or during a long gaming session. The comparison extract gives the Snapdragon multi-core score but does not fully expose the Dimensity figure, so there is no reliable pair to report for that result.
CPU and graphics specifications
CPU
Qualcomm describes the Snapdragon 7s Gen 4 as using a Kryo CPU. MediaTek’s official Dimensity 8400 specification details eight Arm Cortex-A725 cores: one with 1 MB of L2 cache, three with 512 KB each, and four with 256 KB each. It also lists 6 MB of L3 cache and 5 MB of system-level cache.
Rank #2
- Carrier: This phone is locked to Tracfone, which means this device can only be used on the Tracfone wireless network. Tracfone plan required, activating is easy, just 3 steps.
- DISPLAY: Immersive viewing on a 6.7-inch super-bright 120Hz display with powerful stereo speakers and Bass Boost for cinematic entertainment.
- CAMERA SYSTEM: Advanced 50MP Quad Pixel camera captures sharp, detailed photos and videos in any lighting condition
- PERFORMANCE: Lightning-fast 5G connectivity paired with a powerful processor and RAM Boost for smooth multitasking.
- BATTERY LIFE: Long-lasting 5000mAh battery with TurboPower charging technology delivers hours of power in minutes.
For the Max-branded chip, 91mobiles lists one Cortex-A725 core at 3.25 GHz, three at 3.0 GHz and four at 2.1 GHz. Those clock speeds are from a third-party listing, not MediaTek’s official Dimensity 8400 page; they should not be treated as verified base-8400 specifications.
Graphics and gaming
Qualcomm identifies an Adreno GPU and selected Snapdragon Elite Gaming features. MediaTek specifies Mali-G720 MC7 graphics, Frame Rate Converter and HyperEngine Adaptive Gaming Technology 3.0 for the Dimensity 8400. Feature lists do not establish equivalent frame rates, graphics settings or sustained performance across phones. Cooling, power limits and the game itself affect what a handset can maintain.

Memory, connectivity, display and video capabilities
The specifications below describe platform support, not a promise that every phone using a chip implements the maximum configuration. Qualcomm and MediaTek publish different feature details, so a listed capability is not always a directly comparable measure of the finished phone.
| Area | Snapdragon 7s Gen 4 | Dimensity 8400 |
|---|---|---|
| Memory and storage | Not stated on the cited Qualcomm product page | LPDDR5X up to 8533 Mbps; UFS 4 with MCQ |
| Wireless connectivity | Wi-Fi 6/6E and Bluetooth 6.0 capabilities; actual support can depend on phone design and region | Wi-Fi 6E and Bluetooth 5.4 |
| Display | Qualcomm describes platform display features; check the handset for its actual panel specifications | WQHD+ support up to 144 Hz |
| Camera and video | Qualcomm describes platform imaging and display features; check the handset for its actual camera and video options | Support for camera sensors up to 320 MP and 4K60 video capture and playback |
The Snapdragon connectivity details come from Qualcomm’s product page; its FastConnect capability does not guarantee that every phone or region enables every feature. Dimensity 8400 details come from MediaTek’s specifications. A phone maker may choose different memory, storage, screen, camera sensors or regional connectivity support.

What MediaTek’s launch performance claims mean
When MediaTek announced the Dimensity 8400 on December 23, 2024, it claimed up to 41% higher multi-core performance and 44% lower peak power use versus its previous Dimensity 8300. Those are vendor comparisons against the 8300, not results against Snapdragon 7s Gen 4, and should not be read as independent benchmark findings. The claims are in MediaTek’s launch announcement.

Which chip should you choose in a phone?
The benchmark evidence points toward the base Dimensity 8400 for higher scores in the reported AnTuTu 11, Geekbench 6 single-core and PCMark 3.0 comparisons. It does not prove that every Dimensity 8400-series phone will outperform every Snapdragon 7s Gen 4 phone, nor does it settle performance for an 8400 Max handset.

Quick Recap
- Sustained performance: independent tests of the exact handset under extended gaming or heavy workloads, not just a short peak benchmark.
- Cooling and power limits: the phone’s thermal design and settings can change how long it holds performance.
- Memory and storage: confirm the actual RAM and storage type and capacity; platform support for LPDDR5X or UFS 4 does not mean every device includes them.
- Battery, screen and cameras: these affect everyday use and can differ substantially among phones with similar chips.
- Software support, price and network bands: confirm the model and regional version you can actually buy.
- Exact processor variant: verify whether the listing says Dimensity 8400, 8400 Max or 8400-Ultra. The cited evidence does not establish that these names identify equivalent chips.
