Both chipsets use a 4nm manufacturing process, but the Exynos 2400 takes a more aggressive core approach.
- Exynos 2400 features a 10-core layout: 1x Cortex-X4, 2x Cortex-A720, 3x Cortex-A720, and 4x Cortex-A520. The Exynos 2400 has shown improvements in both single-core and multi-core performance compared to its predecessor. In Geekbench tests, it scored 2,067 in single-core and 6,520 in multi-core, which represents a 5% improvement in single-threaded performance and a 22% improvement in multi-threaded performance over the Snapdragon 8 Gen 2-powered Galaxy S23 Ultra.
- Snapdragon 8 Gen 2 comes with an 8-core setup: 1x Cortex-X3, 2x Cortex-A715, 2x Cortex-A710, and 3x Cortex-A510. The Snapdragon 8 Gen 2, on the other hand, has a slight edge in CPU performance, with early Geekbench results showing it outperforming the Exynos 2400 in terms of CPU benchmarks. However, the Exynos 2400 is closing the gap, with recent results showing a reduced performance difference.
Benchmark Comparison:
| Benchmark | Exynos 2400 | Snapdragon 8 Gen 2 |
|---|---|---|
| Geekbench 6 Single | ~2,196 | ~1,985 |
| Geekbench 6 Multi | ~6,971 | ~5,315 |
The Exynos 2400 clearly leads in both single and multi-core performance, showing a significant architectural improvement over Samsung’s previous chips and outperforming the Snapdragon 8 Gen 2 in raw CPU speed.
GPU and Graphics Performance
The Exynos 2400 features an Xclipse 940 GPU, co-developed with AMD, which scored slightly lower than the Adreno 740 GPU in the Snapdragon 8 Gen 2 in early benchmarks. This suggests that the Snapdragon 8 Gen 2 may have a slight advantage in graphics performance.
Despite this, the Exynos 2400 is rumored to have 10 GPU cores, which could indicate promising graphics capabilities and potential improvements in future optimizations.
- Exynos 2400 uses the Xclipse 940 GPU, co-developed with AMD, and runs at 1.10 GHz.
- Snapdragon 8 Gen 2 is equipped with the Adreno 740 GPU, clocked at 0.68 GHz.
Compute Power (GFLOPS):
- Exynos 2400: ~1,825 GFLOPS
- Snapdragon 8 Gen 2: ~1,740 GFLOPS
While the Exynos GPU outpaces Snapdragon slightly in theoretical compute performance, actual gaming performance may vary by optimization. The Adreno GPU has been more consistent in real-world gaming and app rendering.
Power Efficiency and Battery Life
Both processors are manufactured using advanced 4nm processes, aiming to reduce heat and improve battery efficiency. However:
- The Snapdragon 8 Gen 2 has earned praise for its well-balanced efficiency in 2023 devices.
- The Exynos 2400, though more powerful, could consume more power under load, depending on optimization.
Efficiency will largely depend on the specific smartphone’s thermal design and software tuning.
AI and Machine Learning Capabilities
AI tasks are becoming more relevant in mobile devices, from voice recognition to image enhancement.
- Exynos 2400 delivers up to 42 TOPS (trillions of operations per second) via its dual-core AI engine.
- Snapdragon 8 Gen 2 offers around 26 TOPS with its Hexagon NPU.
The Exynos 2400 holds a theoretical advantage in AI performance, which may be noticeable in camera processing, language translation, and background AI tasks in supported apps.
Real-World Usage and Optimization
While benchmarks provide important data, real-world user experience depends on how chipsets interact with software and device hardware.
- Exynos 2400 shows major improvements in thermal control and sustained performance over past Exynos models.
- Snapdragon 8 Gen 2 benefits from years of refinement and stronger app-level optimization, particularly for gaming.
In everyday usage, both chips offer smooth multitasking, fast app loading, and reliable 5G connectivity. Most users would find the differences subtle unless performing demanding tasks like gaming or 4K video editing.
