MediaTek Dimensity 8400 Ultra: AnTuTu, Geekbench scores

Jan 13, 2025

MediaTek’s Dimensity 8400 Ultra was announced in December 2024 as the world’s first all big core chip for the upper mid-range smartphone segment. It’s a powerful chip that brings strong multi-core performance and stands tough against premium chips like the Snapdragon 8s Gen 3. We’ve compared the two chipsets in this article.

All big core CPU design serves the higher performance needs of users than other chipsets. This is not the first of its kind chip from MediaTek. The flagship Dimensity 9400 also features all big CPU cores, and now it’s time for the mid-range segment.

Let’s look at the Dimensity 8400 Ultra’s performance on popular benchmarking tools, including AnTuTu and Geekbench.

MediaTek Dimensity 8400 Ultra Benchmarks

[Note: We performed these benchmark tests on the Poco X7 Pro. Results may vary slightly from device to device because of software optimizations, cooling systems, etc.]

Dimensity 8400 Ultra AnTuTu score

AnTuTu is a popular benchmarking tool to assess different aspects of a device, such as CPU, GPU, memory, and UX performance. The AnTuTu score represents the addition of all values.

On AnTuTu v10, the Dimensity 8400 Ultra has scored 1,590,202 AnTuTu points. That’s an impressive score for a mid-range chipset.

The Dimensity 8400 Ultra beats the popular Snapdragon 7+ Gen 3 chipset and even the flagship Snapdragon 8s Gen 3. The data looks impressive.

	AnTuTu score
Poco X7 Pro (D-8400 Ultra)	1,590,202
Poco F6 (SD 8s Gen 3)	1,509,243
Redmi Note 14 Pro+ (SD 7s Gen 3)	725,812
Realme GT 6T (SD 7+ Gen 3)	1,448,726

Here’s the breakdown of Dimensity 8400 Ultra AnTutu score:

Total AnTuTu score: 1,590,202
- CPU: 370,994
- GPU: 567,384
- Memory: 329,331
- UX: 322,493

Geekbench score

Geekbench evaluates a device’s performance through a series of tests designed around practical scenarios. The tests include image processing, compression (text & image), speech recognition, PDF rendering, and more.

On Geekbench v6, the Dimensity 8400 Ultra gets 1,579 single-core points, which is pretty average among mid-range chipsets, but the score significantly jumps to 6,238 in the multi-core test, and that’s because of all big CPU cores.

	Single core	Multi core
Poco X7 Pro (D-8400 Ultra)	1,579	6,238
Poco F6 (SD 8s Gen 3)	1,857	5,034
Redmi Note 14 Pro+ (SD 7s Gen 3)	1,193	3,234
Realme GT 6T (SD 7+ Gen 3)	1,924	4,571

While the Dimensity 8400 Ultra’s single-core performance is just like any of its competitors, the multi-core performance makes a real difference, where the Dimensity 8400 Ultra takes a good lead.

3D Mark WildLife Extreme Stress Test

3D Mark is a popular benchmark tool to test the gaming performance of a device/chip. The WildLife Extreme Stress test evaluates the performance under sustained heavy loads.

	Overall score
Poco X7 Pro (D-8400 Ultra)	4,086
Poco F6 (SD 8s Gen 3)	2,823
Redmi Note 14 Pro+ (SD 7s Gen 3)	3,087
Realme GT 6T (SD 7+ Gen 3)	2,737

Here, the Poco X7 Pro rocking the Dimensity 8400 Ultra did a better job than its peers, suggesting strong GPU performance. So, you’ll most likely have a better gaming experience with the Dimensity 8400 Ultra than most mid-range chips. However, that also depends on software optimizations, cooling techniques, and more.
