S24’s Exynos 2400 Stumbles: GPU 15% Slower than Snapdragon 8 Gen 3
Recently, the Samsung Galaxy S24, Galaxy S24+, and Galaxy S24 Ultra were launched across various regions, with the series known to introduce the Exynos 2400 version in specific areas. Digital blogger @Golden Reviewer recently conducted a series of performance benchmark tests on the Exynos 2400’s GPU, concluding that the SoC’s GPU overall performance lags behind the third-generation Snapdragon 8 mobile platform by approximately 10-15%.
The Exynos 2400’s GPU, leveraging the AMD RDNA 3 architecture, exhibited a power consumption of about 11.4 W in the GFXBench 1440P test, with an average FPS of 80 frames. In the 3DMark Wild Life Extreme benchmark scenario, it consumed around 10.1 watts with an average FPS of 249 frames. This indicates that the Exynos 2400’s GPU not only falls behind the third-generation Snapdragon 8 mobile platform in power efficiency by about 5.6% but also in performance by roughly 15.8%. Surprisingly, in the aforementioned tests, the Exynos 2400’s energy efficiency even trails behind the second-generation Snapdragon 8 mobile platform and the Dimensity 9200 mobile platform. However, it’s fortunate that its performance still surpasses its predecessor flagship SoC.
Nonetheless, the Exynos 2400 shines in certain aspects, notably outperforming the third-generation Snapdragon 8 mobile platform in the 3DMark Solar Bay ray tracing benchmark test, albeit with 20.5% lower power consumption.
Regarding CPU performance, the processor scored 2266 in single-thread and 7326 in multi-thread tests in Geekbench 6, surpassing the average score of the third-generation Snapdragon 8 mobile platform, according to Notebookcheck. However, the chip still exhibits high power consumption in some tests.
Notebookcheck attributes the Exynos 2400’s high power consumption yet subpar performance primarily to the Cortex-X4 core. The Exynos 2400’s Cortex-X4 core operates at a frequency of only 3.2 GHz but with a high power draw of 7.34W. In contrast, the third-generation Snapdragon 8 mobile platform’s Cortex-X4 core has a frequency of 3.3 GHz with just 6.27W power consumption. Similarly, the Exynos 2400’s Cortex-A720 core also exhibits higher power consumption by about 1W compared to the third-generation Snapdragon 8 mobile platform, despite its lower frequency.
