We are about to compare Exynos vs Snapdragon, which is the most common questions is simple:
“Which processor faster, better performance and stays cooler during gaming and heavy tasks?”
Heat affects performance, battery life, and even long-term durability, so choosing a cooler chipset actually matters more than raw benchmark numbers.

In this detailed breakdown, we compare the latest chipsets from both sides — including Exynos 2400 vs Snapdragon 8 Gen 3 — providing with real-world thermal behavior, gaming temperature trends, efficiency, and sustained performance.

1. Exynos vs Snapdragon: Why Heat Matters

Smartphone SoCs can generate heat from:

• CPU performance
• GPU load during gaming
• AI/ISP workloads
• Higher clock speeds
• Power efficiency differences

A chipset that runs cooler = maintains performance longer without thermal throttling.

Snapdragon is historically known for better thermals, but Exynos 2400 changed the trend with a modern 4nm design and stronger thermal management.

CPU Architecture Comparison (Latest Models)

Feature	Exynos 2400	Snapdragon 8 Gen 3
Process	4nm (Samsung)	4nm (TSMC)
Big Core	Cortex-X4 @ 3.2GHz	Cortex-X4 @ 3.3GHz
Cluster	10-core design	8-core design
GPU	Xclipse 940 (RDNA3)	Adreno 750
AI Engine	17K TOPS	45 TOPS

Snapdragon still wins in efficiency, thanks to TSMC’s 4nm node.
Exynos wins in multi-core performance, thanks to its 10-core setup.

3. Thermal Performance Test (Gaming)

(Based on public gaming stress tests from reviewers such as NLTech, PBK, GSMArena-style data interpretation — no scraping, just benchmark-based conclusions.)

Test Device Assumptions

• Exynos 2400 → Galaxy S24 / S24+
• Snapdragon 8 Gen 3 → Galaxy S24 Ultra, Xiaomi 14, OnePlus 12

15-Minute Gaming Temperature Rise

Lower is better

Exynos 2400	42°C
Snapdragon 8G3	39°C

30-Minute Extreme Gaming (Genshin Impact / COD Mobile)

Exynos 2400	47°C
Snapdragon 8G3	44°C

At extended loads, we can clearcy see that Exynos heats up faster, and especially on GPU-heavy games.
Snapdragon’s Adreno 750 remains much more power efficient.

4. Thermal Throttling Comparison

Sustained Performance After 20 Minutes

Chipset	Performance Retained	Notes
Snapdragon 8 Gen 3	85–90%	Little to no throttling
Exynos 2400	80–85%	Mild throttling under GPU load

Here Snapdragon throttles less, that means more consistent gaming performance. Also you can read the article about how to reduce the phone heat.

5. Battery Drain During Heat Stress

Battery Consumption (per 30 mins Gaming)

Chipset	Battery Drop	Efficiency
Snapdragon 8 Gen 3	9–11%	Excellent
Exynos 2400	11–14%	Moderate

Again, Snapdragon’s efficiency advantage keeps both temperature and battery usage lower.

6. Real-World Temperature Notes

Exynos runs hotter when:

• Playing heavy GPU games
• Using camera/ISP for longer duration video recording
• Running multiple apps and background tasks

Snapdragon can be hotter when:

• Using AI features (because of higher NPU load)
• Pushing extreme sustained performance (benchmarks)

But overall, Snapdragon can maintain cooler average temperatures in most scenarios.

7. “Does Exynos Overheat?” — Modern Answer

Older Exynos chips (990, 2100, 2200) had big heat problems.

But Exynos 2400 improved significantly:

✔ Better multi-core performance
✔ Better thermal distribution
✔ New RDNA GPU is more stable

But still, Snapdragon remains the king of efficiency and thermals.

8. Verdict: Which One Runs Cooler?

Winner: Snapdragon (Cooler & More Efficient)

We can see that Snapdragon 8 Gen 3 runs 2–4°C cooler on average under heavy load.
Its TSMC 4nm process + Adreno GPU efficiency, you can take it as a big difference.

Exynos 2400 is close, but still:

• throttles earlier
• consumes slightly more power
• runs hotter in long gaming sessions

9. Should You Avoid Exynos?

No.
The latest Exynos is a solid performer and not the overheating disaster of old times.

But if cooling and gaming matter the most → Snapdragon is the safer choice.
