Performance Tests: Snapdragon 8 Elite vs Dimensity 9400

Let’s delve into the key performance benchmarks that give us insight into how each chipset performs under real-world conditions.

1. CPU Performance (Geekbench 6)

In Geekbench 6, which measures CPU single-core and multi-core performance, the Snapdragon 8 Elite outshines the Dimensity 9400.

• Snapdragon 8 Elite achieves a 10% higher single-core score and a 17% higher multi-core score compared to the Dimensity 9400. This advantage in multi-core performance highlights the powerful custom Orion cores developed by Qualcomm.
• The Dimensity 9400 still performs respectably, especially considering its reliance on standard ARM Cortex cores rather than Qualcomm’s custom design. This keeps the chip more power-efficient, which we’ll explore further.

2. Gaming & Graphics Performance (3DMark WildLife Extreme)

Both chipsets were subjected to the 3DMark WildLife Extreme test, a graphic-intensive benchmark that simulates high-performance gaming.

• Snapdragon 8 Elite scored 6,774 points, only 6% higher than Dimensity 9400’s 6,383 points, showing a slight edge in graphics performance. However, it’s worth noting that this gap was smaller than expected, especially considering Qualcomm’s reputation for gaming.
• Dimensity 9400’s GPU, the Mali G925 Immortalis, is optimized for efficiency, running slightly cooler than Snapdragon’s Adreno 830, even under heavy load.

3. AI Performance (Geekbench AI)

With AI becoming an essential part of smartphone performance, we conducted tests on both chipsets using Geekbench AI to assess on-device AI processing.

• Snapdragon 8 Elite demonstrates a 33% lead in AI tasks. This advantage is largely due to the dedicated AI cores in the custom Orion architecture, optimized specifically for machine learning and natural language processing tasks.
• The Dimensity 9400 does well but falls behind, making the Snapdragon 8 Elite the better choice for those who rely on AI-driven features in their day-to-day usage.

4. Battery Efficiency & Thermal Management

Battery efficiency and heat generation become critical factors in continuous, heavy-use scenarios like gaming and multitasking.

• Battery Efficiency: The Dimensity 9400 is 45% more efficient than the Snapdragon 8 Elite, which drained 30% of its battery after prolonged usage compared to Dimensity’s 21%. MediaTek’s chip also managed to stay cooler during intensive tasks, showing a lower temperature across several tests.
• Thermal Performance: The Snapdragon 8 Elite runs warmer, sometimes by as much as 5°C compared to the Dimensity 9400. This temperature difference is especially significant for users who engage in long gaming sessions or heavy multitasking.

Core Architecture Breakdown

To fully understand the performance differences, let’s look at each chipset’s core structure.

• Custom Orion Cores in Snapdragon 8 Elite provide higher peak performance for single-threaded tasks but may sacrifice efficiency, contributing to higher battery consumption.
• ARM Cortex Cores in Dimensity 9400, though slightly slower, emphasize efficiency and consistency, making the chip run cooler with less energy.

Key Takeaways on Architecture

1. Qualcomm’s Custom Cores: Qualcomm’s custom Phoenix L and M cores push the Snapdragon 8 Elite to excel in high-performance tasks.
2. ARM-Based Efficiency: Dimensity 9400’s ARM Cortex core design shines in thermal efficiency and battery life, making it a great choice for sustained, heavy use.

Stress Test Results: Real-World Performance Under Pressure

A 20-minute stress test was conducted on both SoCs using 3DMark WildLife Extreme, simulating intense usage over a prolonged period.

• Snapdragon 8 Elite started with a performance lead of around 6.5% but ended up 4.5% behind due to thermal throttling.
• Dimensity 9400 maintained more consistent performance over time, thanks to its superior thermal management, making it a good option for users who demand stability under heavy loads.

Battery Drain Analysis

A direct comparison of battery drain showed that the Dimensity 9400 is more efficient for prolonged use. Here’s how battery life was impacted:

The battery efficiency of the Dimensity 9400 makes it an excellent choice for users who prioritize long-lasting power and cooler device temperatures.

Final Verdict: Which Flagship SoC Should You Choose?

To sum it up, both Snapdragon 8 Elite and Dimensity 9400 bring their own strengths to the table. Here’s a breakdown to help you choose the best SoC based on your needs:

Snapdragon 8 Elite: Best For

• High Performance & AI Tasks: Snapdragon’s custom cores and dedicated AI units make it ideal for users focused on on-device AI, high-speed CPU tasks, and high-end gaming.
