If you wondering how iPhone 7, Galaxy S7 and LG G5 can compared, when none of these phones are released yet. But the currently available information about the Galaxy S7 and the LG G5 can help us conclude that for at least one more year, performance wise the iPhone will be superior than the Android phones.
Every year a new version of the iPhone comes out, and two things are always true:
improved camerabest CPU and GPU performance in the market.
While using it actually, new iPhone performs better although the competitors feature better hardware specifications.
The Galaxy S7 will be backed by Samsung's Exynos 8890 octa-core processor and Qulacomm's Snapdragon 820 SoC. The LG G5 will only get the latter variant .As per the benchmark tests, the comparison between these two CPUs shows that, the Exynos is better in single-core Geekbench tests (2282 vs. 1873), and the Qualcomm ship is speedier in multi-core testing (4979 vs. 5946).
These scores are less than the iPhone 6's score got in single-core tests (2490), and more in multi-core tests (4340). If Apple can achieve the same with the dual-core processor featured in the iPhone 6s, A10 chip will surely a thing to look forward to. Also taking into account the recently performed Qualcomm Snapdragon 820 performance test, Apple's A9 processor (present in iPhone 6s Plus) is superior than the other two processors.
