Samsung Galaxy S24: Performance and efficiency comparisons result in clear defeat for the Exynos 2400
The choice between the Samsung Galaxy S24, the Galaxy S24+ and the Galaxy S24 Ultra depends not least on how well the Samsung Exynos 2400 can perform against the Qualcomm Snapdragon 8 Gen 3. The latest benchmark results from Golden Reviewer now provide a deeper insight into the performance and efficiency of Samsung's latest flagship SoC.
The graphics chip based on AMD's RDNA 3 architecture consumes around 11.4 watts under load, while the somewhat more practical 3DMark Wild Life Extreme benchmark consumes 10.1 watts. This means that the chip consumes 5.6% less energy than the Snapdragon 8 Gen 3, but is also 15.8% slower and thus less efficient. GFXBench 3.1 and Aztec Ruins show similar results. The Exynos 2400 is even less efficient than the Snapdragon 8 Gen 2 and the MediaTek Dimensity 9200, but still more powerful than the flagship chips of the previous generation.
On the other hand, the Exynos 2400 can set itself apart from the competition in at least one discipline, namely ray tracing. Its performance values in the 3DMark Solar Bay ray tracing benchmark are only slightly higher than that of the Snapdragon 8 Gen 3, but with 20.5% lower power consumption.
The processor also managed to achieve a solid performance of 2266 points (single-thread) and 7326 points (multi-thread) in Geekbench 6, thus just surpassing the average result of the Snapdragon 8 Gen 3 in our benchmark database. However, the chip consumes 23 watts in some places during the benchmark run - not a good sign for the battery life of the Galaxy S24.
This high consumption is easy to explain because the ARM Cortex-X4 performance core alone can consume over 7 watts. Despite around 1 watt higher consumption, the core is slower than its counterpart in the Snapdragon 8 Gen 3. The same applies to the Cortex-A720 cores, which consume almost 1 watt more power in the Exynos 2400, but still work slower. Samsung has room for optimization here.
