Qualcomm Snapdragon 898 looks promising!
According to the source, the upcoming Snapdragon 898 shows a remarkable 20% performance boost correlated to the previous Snapdragon 888. Under the ARM public version, the Cortex-X2 has also been substantiated to bring a 16% development in design performance than X1. With all that, it's said that the Snapdragon 898 could surpass the mark of 1 million points in AnTuTu when it arrives.
Though, there could be one big problem for smartphone manufacturers, which is the temperature. The consequence of being powerful is high temperature for the Snapdragon 898. It's said that Qualcomm might be going down the path of increasing frequencies without concerning much about the temperature and leave the problem to someone else. With that said, future flagship devices not only need to compete in terms of power, they might also need to pay more attention to the cooling department.
