Unpredictable Antutu Scores: Why Identical Phones with Similar Hardware Vary
When it comes to smartphone performance benchmarks, particularly the Antutu test, many wonder whether two devices with the same processor and RAM will yield identical results. The answer is a resounding No. Despite having similar hardware, factors such as software optimization, thermal management, storage speed, display resolution, background processes, and manufacturing variations all contribute to varying Antutu benchmark scores. This article delves into these nuances and sheds light on why scores can differ even in seemingly identical devices.
Software Optimization
One of the key reasons behind differing Antutu scores is the way manufacturers optimize their software. Even with the same hardware, different optimization techniques, operating system drivers, and additional software can significantly affect performance. Some phones may have more optimized settings or higher driver performance, leading to better benchmark scores.
Thermal Management
The way a phone manages heat is crucial for maintaining optimal performance during testing. Cooling solutions like vapor chambers, copper layers, and graphite can vary greatly between devices. A phone that better manages its temperature can theoretically sustain higher performance, resulting in a higher benchmark score.
Storage Speed
The type and speed of storage can also impact performance. For instance, a UFS 2.1 memory might be faster than UFS 3.0 in real-world use, and these differences can be reflected in the benchmark scores. The read/write speeds of the internal storage are components of the Antutu score, and even slight variations can lead to differences.
Display Resolution
The same goes for display resolution. A device with a higher resolution might have a different GPU performance, which can influence the overall benchmark score. Even if the core hardware is identical, the rendering capabilities can differ, leading to variance in the score.
Background Processes
Background processes and system tasks can also affect Antutu scores. Any additional processes running in the background can consume resources and lower the overall score. Ensuring a clean environment during the test can help achieve a more accurate score, but it's nearly impossible to maintain a perfectly idle state.
Manufacturing Variations
Even identical components can have slight performance variations due to manufacturing tolerances. Manufacturing processes can introduce minor differences, and these can be enough to affect benchmark scores. This is particularly true for more complex components like processors, which can have slight variances in clock speeds and performance.
Real-World Example: OnePlus 10 Pro
To illustrate these points, let's consider a real-world example. A user ran the Antutu test on a OnePlus 10 Pro and achieved a score of around 970,000 in the afternoon. After cooling the device and optimizing settings, the same user obtained a score above 1,000,000. This highlights how external factors such as heat management and software settings can significantly impact the final benchmark score.
Conclusion: Variability and Scope for External Factors
No two smartphones can achieve the same Antutu score, even if they are the same model. External factors such as ambient temperature, background apps, and real-world usage can all influence the results. The score's six-digit range leaves ample room for variations, and it's nearly impossible to control for all external factors.
In conclusion, while two devices may have similar hardware, the final Antutu score is a result of a complex interplay of factors, making it highly unpredictable and seemingly random.
