Galaxy S7 Loses 25% Performance after gaming for 15 minutes, overheating throttled?

It seems like Samsung might face serious issue on its flagship Galaxy S7 smartphone, with some reports stating that after gaming for around 15 minutes, the Galaxy S7 loses 25% of its performance. Overheating could be the issue, which is something that NordicHardware looked into.

According to report, the SoC performance gets throttled and is forced to reduce its clock speed when the temperature of the chip rises, leaning that the Exynos 8890 and its 14nm FinFET LPP process might not be perfect. During some 3DMark SlingShot benchmarking, the Galaxy S7 runs at 38C, and over five rounds, the performance begins to fall drastically from 2200 points to 1571 point with temp just rising 30°C to 38°C. Keep it in mind that chips manufactured on a smaller (14nm) node tend to have smaller temperature thresholds compared to those made on a bigger manufacturing process.

There are two different Galaxy S7 smartphones in the market, one with Samsung’s own Exynos 8890 processor and another with the Snapdragon 820. If you’re purchasing the one with Samsung’s own Exynos 8890, you might experience these performance-related problems. hopefully Samsung will come out with some update to address this in the near future.
