The first units of Samsung’s Galaxy S7 / S7 Edge have already been subject to benchmark testing, and recently they’ve undergone stress testing as well. Along with Galaxy S7 Edge based on Snapdragon 820, the testing involved Motorola Moto X Pure, HTC One M9, Nexus 6P, iPhone 6S Plus and Galaxy Note 5. As it turned out, Samsung’s flagship did not become overheated and retained the high performance level. However, the model’s graphics processor didn’t deliver good results in the stress test, and the TouchWiz shell of the tested Galaxy S7 Edge began to lag.
With the GPU loaded for a long time, the smartphone began to skip frames, while its display was showcasing visual artifacts.
Similar problems were observed in last year’s flagship Galaxy S6; then they were directly caused by Samsung’s poor optimization of the shell.
