The Dimensity 9400+ has the newer CPU configuration on paper, led by a Cortex-X925 core rated up to 3.73 GHz, while Samsung’s Exynos 2400 pairs a deca-core CPU with Xclipse 940 graphics. But benchmark figures often cited for the Exynos-versus-Dimensity matchup are for the base Dimensity 9400—not the 9400+. That distinction matters: the available scores are useful context, not a direct 9400+ result.
First, distinguish Dimensity 9400 from Dimensity 9400+
MediaTek sells both a Dimensity 9400 and a Dimensity 9400+. They are different chip models, so a result labeled “Dimensity 9400” cannot be reported as a 9400+ benchmark. The head-to-head comparison page cited below covers the base 9400. MediaTek’s official Dimensity 9400+ specifications describe the Plus model, while its Dimensity 9400 page describes the base model.
How the specifications compare
| Category | Samsung Exynos 2400 | MediaTek Dimensity 9400+ |
|---|---|---|
| CPU configuration | Deca-core, tri-cluster architecture; Samsung highlights Arm Cortex-X4 | 1× Arm Cortex-X925 up to 3.73 GHz, 3× Cortex-X4, 4× Cortex-A720 |
| GPU | Xclipse 940, based on AMD RDNA 3; Samsung highlights hardware-accelerated ray tracing | Arm Immortalis-G925 MC12 |
| Manufacturing process | Samsung describes a third-generation 4 nm low-power process | MediaTek lists a 3 nm process |
| AI | Samsung claims a 14.7-fold improvement over Exynos 2200 | MediaTek lists NPU 890 and generative and agentic AI features |
| Memory and storage support | The cited product page emphasizes headline capabilities; a complete maximum configuration is not stated there | LPDDR5X up to 10,667 Mbps and UFS 4 with MCQ |
Sources: Samsung’s Exynos 2400 product page and MediaTek’s Dimensity 9400+ specifications. These are manufacturer platform claims, not guarantees that a particular phone uses every supported memory or storage feature. Samsung’s AI comparison is specifically against the Exynos 2200; it is not a claim that the Exynos 2400 outperforms the Dimensity 9400+ in AI.

What the published benchmark numbers show—and do not show
NanoReview’s page compares Exynos 2400 with the base Dimensity 9400. As displayed on October 7, 2026, it reported the following database aggregates:

| Benchmark | Exynos 2400 | Dimensity 9400 (base model) | Reported samples |
|---|---|---|---|
| Geekbench 6 single-core | 2,115 | 2,797 | 38 Exynos devices; 22 Dimensity devices |
| Geekbench 6 multi-core | 6,826 | 8,767 | 38 Exynos devices; 22 Dimensity devices |
| AnTuTu 11 total | 2,046,435 | 2,825,187 | 93 Exynos devices; 72 Dimensity devices |
These figures are reported by NanoReview’s Exynos 2400 vs Dimensity 9400 comparison. They are mixed-device database results, not measurements from a controlled, matched-device test, and the Dimensity column is not the 9400+. They support a comparison of the listed Exynos 2400 and base 9400 samples in those benchmark versions; they do not establish how the 9400+ scores against the Exynos 2400.
Device identity matters as much as the chip label. Geekbench’s Android benchmark listings associate results with specific devices, including a Galaxy S24 using Exynos 2400 and a Galaxy Tab S11 Ultra using Dimensity 9400+. That is useful evidence of device-level variation, not a same-condition head-to-head test of the two processors.

- Please note, this device does not support E-SIM; This 4G model is compatible with all GSM networks worldwide outside of the U.S. In the US, ONLY compatible with T-Mobile and their MVNO's (Metro and Standup). It will NOT work with other CDMA carriers, and it is also not compatible with their MVNO (Visible, Xfinity Mobile, US Mobile, Cricket Wireless, etc).
- Compatibility with certain third-party devices and accessibility accessories, including some hearing aids, may vary depending on manufacturer support, Bluetooth protocols, software compatibility, and regional firmware limitations. For additional hearing aid compatibility information, please refer to Samsung’s official support documentation.

What these differences mean when choosing a device
CPU speed
The 9400+ specification lists a Cortex-X925 peak frequency of up to 3.73 GHz, alongside three Cortex-X4 and four Cortex-A720 cores. The Exynos 2400 is a deca-core design. Core count and maximum clock alone do not determine everyday speed: workloads, software, cooling, and the phone or tablet’s power limits also shape performance.

The chips take different GPU approaches: Samsung identifies the Xclipse 940 as AMD RDNA 3-based and highlights hardware ray tracing; MediaTek lists an Immortalis-G925 MC12. Those specifications do not settle which device delivers higher frame rates, better image quality, or more stable performance over a long gaming session. A meaningful gaming comparison needs tests of the actual devices, games, graphics settings, and sustained run time.

Efficiency and thermals
The listed process labels—Samsung’s third-generation 4 nm low-power process and MediaTek’s 3 nm process—are not, by themselves, a complete efficiency comparison. The available sources do not establish matched handset battery-life, thermal, or sustained-performance results for Exynos 2400 versus Dimensity 9400+.
Memory, storage, and device implementation
MediaTek’s LPDDR5X speed and UFS 4 with MCQ are supported platform specifications, not proof that every 9400+ device implements the maximum configuration. A phone maker’s memory, storage, cooling, battery, firmware, and regional model choices can affect the experience. The official 9400+ page surfaced in this comparison is categorized under tablets, so confirm the exact product and form factor rather than assuming a handset match.

How to make a fair comparison before buying
- Confirm the exact chip. Check the device’s full model and market-specific specification sheet. Do not treat Dimensity 9400 and Dimensity 9400+ as interchangeable.
- Compare the actual devices. Look for tests using the same benchmark version and comparable software, ambient conditions, and performance settings. Scores from different devices are not a controlled chipset-only test.
- For gaming, check sustained behavior. Seek frame-rate and temperature results from the game and settings you care about, not GPU names alone.
- For battery life, use device-level results. Chip process labels do not account for screen, battery capacity, radios, firmware, or power management.
- Verify the regional variant and full configuration. Confirm processor, memory, storage, cooling, price, and software support on the specific device available to you.
Samsung’s Exynos 2400 product page and MediaTek’s Dimensity 9400+ specification page establish headline chip features. MediaTek’s announcement dates the 9400+ introduction to April 10, 2025: Dimensity 9400+ announcement.
