Introduction
In 2025, the battle for the best flagship processor is fiercer than ever. The top contenders – Snapdragon 8 Gen 4, MediaTek Dimensity 9400 Plus, and Apple A18 Pro-are pushing the boundaries of smartphone performance. If you’re wondering which chip delivers the best experience, this in-depth comparison of Snapdragon 8 Gen 4 vs Dimensity 9400 Plus vs Apple A18 Pro will help you decide.
Architecture and Manufacturing Process
All three processors-Snapdragon 8 Gen 4, Dimensity 9400 Plus, and Apple A18 Pro-are built on advanced TSMC 3nm processes. However, there are subtle differences:
- Snapdragon 8 Gen 4 uses TSMC’s N3E process and features Qualcomm’s custom Orion core, previously seen in their X Elite processors. This core is designed for high-end tasks, offering improved stability, thermals, and efficiency.
- Dimensity 9400 Plus is an overclocked version of the standard 9400, with its ARM Cortex-X925 core clocked at 3.7 GHz and a slightly enhanced GPU for better efficiency.
- Apple A18 Pro is based on TSMC’s N3P process, which is the most efficient among the three. This efficiency translates to longer battery life and less heat, especially in the iPhone 16 Pro and Pro Max, the only devices currently using this chip.
Benchmark Performance
Single-Core and Multi-Core Scores
- Apple A18 Pro leads in single-core performance, scoring between 3300 and 3400 in Geekbench tests, thanks to its highly optimized architecture.
- Snapdragon 8 Gen 4 follows, reaching up to 3000 in single-core Geekbench scores.
- Dimensity 9400 Plus trails slightly in single-core but catches up in multi-core performance, where Snapdragon 8 Gen 4 takes the top spot, followed by Dimensity 9400 Plus, and then Apple A18 Pro.
GPU and Graphics
- Dimensity 9400 Plus stands out in GPU benchmarks, especially in 3DMark, due to its efficient Immortalis GPU.
- Snapdragon 8 Gen 4 also offers strong GPU performance with support for ray tracing, making it a top choice for high-fps gaming.
- Apple A18 Pro’s GPU is less powerful on paper but excels in real-world gaming thanks to Apple’s Metal API and game optimization for iOS devices.
Real-World Performance
Gaming
- Snapdragon 8 Gen 4 and Dimensity 9400 Plus both provide excellent gaming experiences on Android, with consistent high FPS and support for advanced graphics features.
- Apple A18 Pro delivers smooth, stable gaming, especially in titles optimized for iOS, despite its lower benchmark numbers.
AI and Machine Learning
- Snapdragon 8 Gen 4 leads in AI tasks, thanks to its advanced NPU and on-device AI capabilities.
- Dimensity 9400 Plus performs well but lags slightly behind Snapdragon in AI benchmarks.
- Apple A18 Pro is strong in computational photography but is less versatile in broader AI applications compared to its rivals.
Efficiency and Battery Life
- Apple A18 Pro is the most efficient, offering superior battery life due to its advanced N3P process.
- Snapdragon 8 Gen 4 and Dimensity 9400 Plus are efficient but not on the same level as Apple’s chip.
Device Availability and Software Support
- Snapdragon 8 Gen 4 is widely available across flagship Android devices, such as the Galaxy S25, OnePlus 13, and Realme GT 7 Pro. It also offers up to 8 years of Android updates, a significant advantage for long-term users.
- Dimensity 9400 Plus is currently limited to select devices, like the Vivo X200 Pro and a few upcoming models.
- Apple A18 Pro is exclusive to the iPhone 16 Pro and Pro Max.
