Analyzing the performance of Samsung Galaxy J7 Prime and Oppo F1s. Which phone boasts stronger performance, smooth gaming experience, and whether a 720p or 1080p display will emerge victorious.
1. Comparing Samsung Galaxy J7 Prime and Oppo F1s (Part 2): Performance Analysis
Following the design comparison in part 1, let's delve into testing the performance of these two 6-million phones. In theory, Oppo F1s holds an advantage with its powerful GPU and a 720p display instead of 1080p. However, reality often tells a different story.
To assess the performance of these devices, we conducted three different tests. The first involved running benchmark applications, the second tested response speed when running applications, and the final test evaluated performance during gaming sessions.
Firstly, let's review some information about these two phones. Both utilize octa-core processors, but one employs Exynos while the other uses MediaTek. Samsung operates at 1.6GHz while Oppo runs at 1.5GHz, theoretically giving Samsung an edge in CPU performance.
Regarding the graphic chip,
Benchmark:
Across all benchmark tests, the scores of J7 Prime and F1s are similar, with negligible differences despite J7 Prime slightly edging ahead. While unsurprising, two aspects caught my attention: multi-core GeekBench scores and graphic scores.
If J7 Prime and F1s show minimal disparity in multi-core performance, the story changes entirely for multi-core scores. J7 Prime exhibits a robust 30% increase, a considerable gap. The explanation? J7 Prime utilizes Exynos 7870 supporting big.Little architecture, enabling both CPU clusters to be activated simultaneously for heavy processing tasks, whereas F1s with MT6750 only utilizes one of the two clusters. If you're looking for a CPU equivalent to 7870, it must be MT6753, featuring big.Little support.
In reality, instances where all 8 processing cores are activated are rare, yet it significantly impacts loading heavy applications, as evident in the gaming benchmarks below.
Concerning graphic benchmarks, I was surprised to find Samsung outperforming. The 3D Mark score on J7 Prime reaches 298 points while F1s only manages 241. This difference likely stems from two factors: interface and Android version. Samsung customizes J7 Prime's Android version to a lesser extent compared to F1s, while the device runs on Android 6.0, better optimized for lower-end configurations compared to the outdated Android 5.1 on Oppo F1s.
Responsiveness:
In this aspect, Oppo claims the entire advantage. Nearly all applications respond instantly upon touch. For daily tasks, this stands as a significant advantage.
Heavy Gaming and App Loading:
Upon tapping an application, it immediately responds, followed by the processing by the CPU. The stronger the chip, the shorter the loading time. Clearly, J7 Prime outperforms F1s in this aspect with big.Little. The difference in game loading times between the two devices can reach up to 50%, a substantial figure. If Oppo equipped MTK6753, the story would be different, but unfortunately, they stopped at 6750.
Conclusion:
While F1s holds the advantage in daily tasks such as calling, messaging, or emailing, i.e., lightweight applications, all advantages in gaming or heavy applications belong to J7 Prime. Most notably, when activating the camera, F1s displays the screen immediately, whereas the first device to load the entire screen and capture is J7 Prime. Overall, the performance advantage heavily favors Samsung.
