The Dimensity 7400X has a newer published CPU configuration and leads in some available aggregate benchmark comparisons, but those scores are not from matched tests and do not guarantee a faster phone. Snapdragon 7 Gen 1 documents a higher peak modem speed and support for both mmWave and sub-6 GHz. For a buying decision, compare the complete phone—not just its processor.
At a glance: what differs
| Feature | Snapdragon 7 Gen 1 | Dimensity 7400X |
|---|---|---|
| CPU | 64-bit Qualcomm Kryo; 2.4 GHz standard variant, with an accelerated edition listed up to 2.5 GHz. Qualcomm advises checking the phone maker for the device’s CPU speed. | Four Arm Cortex-A78 cores up to 2.6 GHz and four Cortex-A55 cores. |
| Graphics | Qualcomm Adreno; the product brief lists supported graphics APIs. | Arm Mali-G615 MC2. |
| Manufacturing process | 4 nm, according to Qualcomm’s product comparison. | 4nm-class process, according to MediaTek. |
| Cellular modem | Snapdragon X62; up to 4.4 Gbps peak downlink, with mmWave and sub-6 GHz support. | Up to 3.27 Gbps peak downlink; MediaTek lists sub-6 GHz 3CC carrier aggregation. |
| Wi-Fi and Bluetooth | Wi-Fi 6E and Bluetooth 5.2. | Wi-Fi 6E and Bluetooth 5.4. |
| Camera and display platform limits | Qualcomm lists capture support up to 200 MP and display limits in its product brief; a phone’s actual features depend on its maker. | MediaTek lists camera support up to 200 MP, 4K video capture at 30 fps, and display support up to WFHD+ at 120 Hz or FHD+ at 144 Hz. |
These are platform capabilities, not a checklist of features guaranteed in every handset. Manufacturers choose the camera sensors, screen, memory, cooling, antennas, and other components. See the Qualcomm Snapdragon 7 Gen 1 product page, Qualcomm product brief, and MediaTek Dimensity 7400X product page for the manufacturers’ specifications.
CPU and graphics: a configuration advantage, not a phone-speed guarantee
The Dimensity 7400X’s listed CPU arrangement is four Cortex-A78 performance cores, clocked up to 2.6 GHz, plus four Cortex-A55 efficiency cores. Snapdragon 7 Gen 1 uses Qualcomm’s Kryo CPU architecture; its standard variant is listed at 2.4 GHz, while an accelerated edition reaches up to 2.5 GHz. The exact clock in a particular Snapdragon phone can vary, so the chipset name alone does not establish its operating speed.

What the benchmark comparisons show—and what they do not
Some published benchmark data puts the Dimensity 7400X ahead in aggregate scores, but the available figures come from different sources, devices, test versions, and sample pools. They are not a controlled head-to-head test, so they should not be combined into a single definitive ranking.
| Source and test | Dimensity 7400X | Snapdragon 7 Gen 1 | How to read it |
|---|---|---|---|
| GadgetVersus AnTuTu (version not stated in the cited comparison) | 675,389 | 595,845 | Source-reported comparison; device and testing conditions are not established as matched. |
| GadgetVersus Geekbench 6 single-core | 1,089 | 941 | Reported scores, not a controlled comparison of otherwise identical phones. |
| GadgetVersus Geekbench 6 multi-core | 3,081 | 2,674 | Reported scores; handset, firmware, and cooling can affect results. |
| NanoReview AnTuTu 11 average, Snapdragon 7 Gen 1 page | not stated (NanoReview does not provide a corresponding 7400X value in the cited data) | 859,516 | A source-specific average from AnTuTu 11; not directly comparable with GadgetVersus’s AnTuTu figure. |
| NanoReview Geekbench 6, Snapdragon 7 Gen 1 page | not stated (NanoReview does not provide a corresponding 7400X value in the cited data) | 1,044 single-core; 2,785 multi-core | Source-reported Snapdragon results; not a matched comparison with the GadgetVersus scores. |

For source data, see the Notebookcheck Dimensity 7400X benchmarks and specifications, GadgetVersus comparison, and NanoReview Snapdragon 7 Gen 1 page. Benchmark releases, device selection, firmware, cooling, and sample sizes differ. A higher result on one comparison page is evidence about those reported tests, not a guarantee that every 7400X handset will outperform every Snapdragon 7 Gen 1 handset.

MediaTek lists up to 3.27 Gbps for the Dimensity 7400X and details sub-6 GHz 3CC carrier aggregation. Those are platform specifications, not promised download speeds: actual service depends on the phone’s regional variant, supported bands, carrier deployment, signal conditions, and network congestion.

Camera, display, and memory features depend on the handset
The platform maximums can help explain what a manufacturer may build, but they do not establish the experience you will get. A 200 MP camera capability does not mean a phone has a 200 MP sensor, and support for a display resolution or refresh rate does not mean the handset uses that panel. Image quality also depends on the sensor, lenses, processing, and software.
The same distinction applies to memory and storage: a chipset’s supported configurations do not tell you how much RAM or storage a particular phone includes. Compare the exact handset model and regional configuration for camera hardware, screen resolution and refresh rate, memory, storage, and recording modes.

How to choose between phones using these chips
- Confirm the exact model and market variant. A phone name can cover different regional configurations. Check its official specification page for the chipset, cellular bands, memory, storage, and enabled features.
- Look for sustained-performance evidence. If gaming or long workloads matter, prioritize tests of the actual handset under sustained use. Short benchmark runs may not show how heat and power limits affect performance over time.
- Compare battery and display together. Battery capacity alone does not establish battery life; screen characteristics, software, and workload matter too. Check independent phone-level testing if available.
- Assess camera hardware and software. Compare the sensors and lenses, video modes, stabilization, and sample images of the specific models rather than relying on the chipset’s maximum camera capability.
- Check software support, price, and availability. Update commitments and current pricing belong to the phone maker and seller, not the chipset. Compare what is offered for the exact handset where you live.
Bottom line: which chipset is better?
The Dimensity 7400X has the more clearly specified four-core Cortex-A78 CPU cluster, and some independent benchmark comparisons report higher aggregate results for it. Snapdragon 7 Gen 1, meanwhile, documents higher peak modem throughput and mmWave as well as sub-6 GHz support. Neither difference settles which phone is better: for most buyers, the specific handset’s sustained performance, battery, display, camera implementation, regional connectivity, software support, and price are more decisive than the chipset name alone.
