Xiaomi's new Redmi Turbo 4 debuted this week as the first Dimensity 8400 device on the market. The MediaTek chipset arrives as a sub-premium alternative to upcoming Qualcomm offerings like the Snapdragon 7+ Gen 4, and benchmarks have now revealed the SoC's performance numbers.
On Geekbench 6, the Dimensity 8400 on the Turbo 4 records a single-core score of 1639 and a multi-core score of 6500. That's a disappointing peak performance upgrade on the Dimensity 8300, which scores 1548 on Geekbench's single-core test. Those numbers are consistent when the Dimensity 8400 is stacked against similar chipsets. It fails to outperform rivals like the Snapdragon 7+ Gen 3 and Snapdragon 8s Gen 3 on the single-core test, but typically blows them away on the multi-core one.
On AnTuTu's CPU test, the Redmi Turbo 4 earns a score of 394,810. Comparatively, a Snapdragon 8s Gen 3 device like the iQOO Z9 Turbo scores 374,782, while a Snapdragon 7+ Gen 3 phone like the OnePlus Ace3V scores 369,828 on the same test.
On the GPU side, the Dimensity 8400 on the Redmi Turbo 4 finishes with a score of 4,086 on 3DMark's WildLife Extreme test, ahead of the Snapdragon 8s Gen 3 (3161). That carries over to AnTuTu's GPU test, where the Turbo 4 scores 658,114, vs the Snapdragon 8s Gen 3's 506,197 and the Snapdragon 7+ Gen 3's scores of 472,913.
The Dimensity 8400 can be summarily said to offer both better CPU and GPU performance than those two Qualcomm chipsets. That's to be expected, of course, as both the Snapdragon 8s Gen 3 and Snapdragon 7+ Gen 3 are effectively last-gen at this point. The Dimensity 8400's actual competition will be the successors to those SoCs. Compared to past Qualcomm flagship chipsets, the Dimensity 8400 does outperform the Snapdragon 8 Gen 2 on both the CPU and GPU sides, but fails to keep up with the Snapdragon 8 Gen 3.
