Quantifying Power: Benchmark Analysis
Architectures are one thing, but how do they perform? We dive into the numbers from Geekbench and AnTuTu.
Geekbench 6 CPU Performance
AnTuTu 10 Overall Score
Note: Benchmark scores are compiled from a range of pre-release and launch-day sources. Performance can vary based on device thermals, software, and testing conditions. These charts represent the higher end of reported scores to show peak potential.
The Endurance Test: Sustained Performance & Thermals
Peak benchmark scores only tell half the story. In the real world, especially during extended gaming sessions, a chip's ability to manage heat and maintain performance is paramount. Thermal throttling—the process of reducing clock speeds to prevent overheating—is the great equalizer, and the physical design of the phone is as important as the silicon itself.
The Throttling Factor
Reports indicate that all three 3nm chips generate significant heat. The Exynos 2500, particularly in the compact Galaxy Z Flip 7, throttles heavily to stay within its thermal budget. The Snapdragon 8 Elite, with its high clock speeds, also requires robust cooling solutions. The key takeaway is that a phone with a superior cooling system (e.g., a large vapor chamber) will deliver a better-sustained performance, regardless of which of these powerful chips is inside.
The Intelligence Engine
The defining feature of the 2025 SoC generation is the pivot toward powerful on-device Artificial Intelligence. The competition is evolving from a simple contest of Trillion Operations Per Second (TOPS) to a more nuanced race to enable specific, marketable generative AI experiences.

Connectivity: The Satellite Race
All three chips feature Wi-Fi 7 and advanced 5G modems. The key differentiators are in satellite connectivity: The Exynos 2500 and Snapdragon 8 Elite integrate NTN for emergency messaging, while the Dimensity 9400 offers an innovative direct phone-to-phone connection for off-grid communication.
Content Creation: The AI-Powered ISP
The camera battle is fought with AI. The Snapdragon 8 Elite offers real-time semantic segmentation for video, while the Dimensity 9400 boasts Gen-AI Super Zoom and AI Audio Focus. The Exynos 2500 leverages its powerful NPU for advanced noise reduction. Both Snapdragon and Dimensity pull ahead with 8K/60fps video capture.
Memory: The Unsung Hero
Often overlooked, memory speed is critical. The Dimensity 9400 holds a significant advantage, supporting blazing-fast 10,667 Mbps LPDDR5X RAM. This provides a wider data pipeline for the entire chip, boosting system-wide performance and contributing to its excellent AnTuTu scores, leaving the Snapdragon (5300 MHz) and Exynos (4800 MHz) behind.
