It is designed with flip phones and their dual-screen use in mind; Motorola’s razr 60 (also called the Razr 2025 in some coverage) is a useful real-world example. Published Razr tests land around 1,000 in Geekbench 6 single-core and 3,000 multi-core, but those are handset results, not guaranteed scores for every 7400X phone.
What is the Dimensity 7400X, and who is it for?
The 7400X is an octa-core, 4nm-class mobile platform with four Arm CPU cores clocked up to 2.6GHz. Its distinguishing design point is support for the dual displays used by flip phones. MediaTek says the “X” denotes technology for dual-screen smartphones, citing the Razr 60 as an example: MediaTek’s explanation.
That makes the chip a sensible fit for a midrange foldable where checking notifications or using the outer display matters alongside everyday app performance. It does not, by itself, establish that every phone with the 7400X will perform identically; memory, cooling, software and device design also affect the experience.
Dimensity 7400X specifications
| Specification | What is documented |
|---|---|
| CPU | Octa-core, with four Arm cores up to 2.6GHz; Motorola’s regional Razr 60 sheet lists clusters at 2.0GHz and 2.6GHz. |
| Manufacturing class | 4nm-class, as described by MediaTek and Motorola. |
| GPU | Arm Mali-G615 MC2 in Motorola’s Razr 60 implementation. |
| AI | NPU 655; Motorola describes it as sixth-generation. |
| Memory and storage example | Motorola’s listed Razr 60 configuration includes 8GB LPDDR4X RAM and 256GB UFS 2.2 storage. Motorola notes RAM can vary by market. |
| Display capabilities | MediaTek lists support for dual flip-phone displays, WFHD+ resolution up to 120Hz and 10-bit color. The Razr 60 has a 6.9-inch main pOLED display and a 3.6-inch outer pOLED display; the cited regional configuration lists refresh rates up to 120Hz main and 90Hz external. |
| Imaging platform | MediaTek lists support for a 200MP main camera, 12-bit HDR-ISP, Google Ultra HDR, hardware face detection and multi-frame noise reduction. These are platform capabilities, not a claim that a particular phone includes a 200MP camera. |
| Connectivity | MediaTek lists up to 3.27Gbps 5G downlink with advanced 3CC carrier aggregation, dual 5G SIM with dual VoNR, tri-band 2×2 Wi-Fi 6E and Bluetooth 5.4. Realized support depends on phone implementation and network availability. |
For the handset-specific details, see Motorola’s Razr 60 specifications and MediaTek’s Dimensity 7400X feature list. Regional names and configurations may differ, so check the listing for the exact market model.

Dimensity 7400X benchmark results
The available published scores come from Motorola’s Razr 60 / Razr 2025, not a controlled test of the chip across multiple phones.
| Test and source | Razr 60 / Razr 2025 result | Context |
|---|---|---|
| Geekbench 6.7.1, submitted to Geekbench Browser July 4, 2026 | 1,078 single-core; 2,899 multi-core | One submitted Android AArch64 run. The system page identifies Android 16, Mediatek MT6878, eight cores with clusters at 2.0GHz and 2.6GHz, and 11.15GB reported memory. It is not a controlled average. View the Geekbench result. |
| Geekbench 6, Tom’s Guide review | 1,089 single-core; 3,075 multi-core | Tom’s Guide’s Razr 2025 review measurement. |
| 3DMark Wild Life Unlimited, Tom’s Guide review | 22.2 FPS | Graphics result for the reviewed Razr 2025. |
| Adobe Premiere Rush transcoding, Tom’s Guide review | 1 minute 21 seconds | Time reported for the reviewed Razr 2025. |
Tom’s Guide’s comparison table recorded 1,055/2,999 in Geekbench 6, 19 FPS in 3DMark Wild Life Unlimited and 54 seconds in Premiere Rush for the 2024 Razr with Dimensity 7300X. The publication characterized the newer phone’s CPU gain as about 3% and graphics as improved, while its video-transcoding time was 27 seconds longer. These comparisons involve complete phones and their respective test conditions, rather than isolating the processor. See Tom’s Guide’s Motorola Razr 2025 review.

How fast does it feel in normal use and games?
Tom’s Guide found app switching and assistant use adequate on its Razr 2025 review unit. It also observed stutters while loading scenes in PUBG Mobile, while a lighter side-scrolling game played smoothly. Those observations suggest ordinary use is within the chip’s comfort zone, but demanding games may expose its midrange limits; they describe one phone, not every 7400X implementation.
The same Tom’s Guide comparison shows the gap to higher-end phones in those particular tests: its Razr Ultra 2025 with Snapdragon 8 Elite scored 2,719/8,342 in Geekbench 6 and 145.3 FPS in 3DMark Wild Life Unlimited; the Galaxy Z Flip 7 with Exynos 2500 scored 2,286/8,079 and 114.6 FPS. Phone design, cooling, software and test conditions differ, so these figures compare complete devices rather than provide a chip-only ranking.

How to read MediaTek’s performance claims
MediaTek’s 2025 material makes several comparisons, but these are manufacturer claims rather than independent measurements. The available infographic text does not provide enough protocol detail to reproduce them independently.
- MediaTek claims a 10% GPU performance boost over the previous generation.
- It claims up to 25% more power efficiency in popular everyday applications without compromising performance.
- For the UNET Benchmark, it claims up to 94% faster performance measured in FPS and up to 63% better power efficiency measured in FPS/W.
- It lists up to 3.27Gbps 5G downlink with advanced 3CC carrier aggregation as a platform capability, not a guaranteed speed on a given network.
These figures should be read within the workloads and qualifications MediaTek names, not as predicted whole-phone gains or typical battery-life improvements. The platform specification and claims are on MediaTek’s official 7400X page.

How to compare phones that use the 7400X
When comparing benchmark results, match the test and version first: CPU scores, graphics frame rates, AI tests and sustained gaming measure different things. Then account for each handset’s memory configuration, thermal behavior and software. A benchmark from one phone cannot separate the SoC from those factors, and the available published evidence here is centered on one handset family rather than a broad sample.
For foldables, also compare the features that shape daily use: outer-display size and refresh rate, connectivity supported in your region, and how the phone implements the chip’s dual-screen capabilities. MediaTek’s supported display or connectivity maximum is not proof that a particular model includes or enables every listed feature.
