Snapdragon 8s Gen 4 vs Exynos 2400e Specs & Benchmarks

The Snapdragon 8s Gen 4 and Exynos 2400e are two 2024 smartphone chipsets aimed at upper-midrange and flagship-lite devices. In short, the Snapdragon 8s Gen 4 offers better GPU gaming performance and efficiency, while the Exynos 2400e has a more powerful CPU in multi-core workloads but runs hotter and consumes more power. Below we break down the full specs, benchmark comparisons, and real-world implications to help you decide which chipset suits your needs.

Background: Where These Chips Fit

Qualcomm’s Snapdragon 8s Gen 4 (SM8735) is a trimmed version of the flagship Snapdragon 8 Gen 4, designed for phones priced around $500–700. It uses a 4nm TSMC process and features a custom Oryon CPU core layout. Samsung’s Exynos 2400e is a slightly underclocked variant of the Exynos 2400, found in the Galaxy S24 FE and some regional Galaxy S24 models. It uses Samsung’s 4nm LPP+ process and a 10-core CPU cluster. Both chips support 5G, Wi-Fi 7, and LPDDR5X RAM, but they differ significantly in architecture and thermal behavior.

Specifications Comparison

• CPU: Snapdragon 8s Gen 4: 1x Oryon prime core @ 3.0 GHz, 3x Oryon performance @ 2.8 GHz, 4x Oryon efficiency @ 2.0 GHz. Exynos 2400e: 1x Cortex-X4 @ 3.1 GHz, 2x Cortex-A720 @ 2.9 GHz, 3x Cortex-A720 @ 2.6 GHz, 4x Cortex-A520 @ 1.9 GHz.
• GPU: Snapdragon 8s Gen 4: Adreno 830 (same as the full 8 Gen 4 but clocked lower). Exynos 2400e: Xclipse 940 (based on AMD RDNA 3).
• Process: Snapdragon: TSMC 4nm (N4P). Exynos: Samsung 4nm (LPP+).
• Memory: Both support LPDDR5X up to 4200 MHz (Snapdragon) and 4266 MHz (Exynos).
• Modem: Snapdragon X70 5G (integrated). Exynos 2400e uses the Exynos 5300 5G modem.
• AI: Snapdragon has a Hexagon NPU with 45 TOPS; Exynos has a 17K MAC NPU (roughly 34 TOPS).

Benchmark Results (AnTuTu & Geekbench)

In AnTuTu 10, the Snapdragon 8s Gen 4 typically scores around 1.9–2.0 million points, while the Exynos 2400e scores about 1.7–1.8 million. The GPU subscore is where the Snapdragon pulls ahead by 20–30% in stress tests like 3DMark Wild Life Extreme. In Geekbench 6, the Exynos 2400e often edges out single-core (around 2200 vs 2100) and multi-core (6800 vs 6400) due to its higher core count and clock speeds. However, sustained performance is better on the Snapdragon because it throttles less under prolonged load.

Real-World Gaming Performance

In games like Genshin Impact and Honkai: Star Rail, the Snapdragon 8s Gen 4 maintains higher average frame rates (55–60 fps at high settings) with fewer frame drops. The Exynos 2400e also hits 50–60 fps but tends to drop to 40 fps after 15–20 minutes of play due to thermal throttling. The Adreno 830 GPU is more efficient, drawing less power per frame. For emulation (e.g., Switch emulators), the Snapdragon is the clear winner because of better driver support and raw GPU compute.

Thermals and Battery Life

The Exynos 2400e runs noticeably hotter under stress. In thermal imaging tests, the Exynos chip reaches 45–48°C on the phone’s surface after 30 minutes of gaming, while the Snapdragon stays around 40–43°C. This translates to better battery life on Snapdragon devices: about 10–15% longer in video playback and web browsing. The Exynos 2400e’s 10-core CPU cluster also draws more idle power, which hurts standby time.

How to Choose Between Them

If you prioritize gaming, sustained performance, and battery efficiency, choose a phone with the Snapdragon 8s Gen 4. If you want slightly better multi-core CPU performance for productivity tasks like video editing or compiling code, the Exynos 2400e is acceptable, but be prepared for more heat and lower battery life. Also consider the phone’s cooling system: some Exynos phones have vapor chambers that mitigate throttling, but the Snapdragon still has the edge in most scenarios.

Common Problems and Misconceptions

A common misconception is that the Exynos 2400e is “the same” as the Exynos 2400. It’s not: the 2400e has lower clock speeds and a less powerful NPU, making it about 10% slower in AI tasks. Another issue is that some users report Wi-Fi connectivity drops on Exynos 2400e devices due to the modem’s firmware. This is not widespread but has been noted in forums. For the Snapdragon 8s Gen 4, some early units had GPU driver bugs that caused crashes in specific games, but updates have largely fixed these.

Frequently Asked Questions

Is the Snapdragon 8s Gen 4 better than the Exynos 2400e for emulation?

Yes, the Snapdragon 8s Gen 4 is significantly better for emulation due to its Adreno GPU’s superior driver support and raw performance. Switch emulators like Yuzu run at higher and more stable frame rates on Snapdragon devices.

Which chip has better AI performance?

The Snapdragon 8s Gen 4 has a more powerful Hexagon NPU (45 TOPS vs ~34 TOPS), so it handles on-device AI tasks like photo editing and voice recognition faster and more efficiently.

Does the Exynos 2400e support ray tracing?

Yes, both chips support hardware ray tracing. The Exynos 2400e’s Xclipse 940 (RDNA 3) supports it, but the Snapdragon’s Adreno 830 provides better ray tracing performance in supported games.

Which chip is more power efficient?

The Snapdragon 8s Gen 4 is more power efficient, especially under load. It uses TSMC’s N4P process, which is more mature and efficient than Samsung’s 4nm LPP+ used in the Exynos 2400e.

Will the Exynos 2400e overheat in daily use?

No, in normal daily use (browsing, social media, calls) it stays cool. Overheating only occurs during sustained heavy gaming or video recording, where it throttles more aggressively than the Snapdragon.

Can I upgrade from Exynos 2400e to Snapdragon 8s Gen 4?

No, these are soldered onto the motherboard. You cannot upgrade the chipset; you would need to buy a new phone with the desired chip.

Final Verdict

For most users, the Snapdragon 8s Gen 4 is the better chip overall: it offers superior gaming, better battery life, and more efficient AI processing. The Exynos 2400e is not a bad chip, but it struggles under sustained load and has less efficient power consumption. If you’re choosing between two phones with these chips, the Snapdragon 8s Gen 4 is the safer bet for a smooth and long-lasting experience.
