The Galaxy S9, like the S9+, sports a Qualcomm Snapdragon 845 chipset that benchmarks the fastest we've seen so far of any Android phone. It also supports every band and carrier aggregation combination used by US carriers today, just like the S9+. That's going to make a huge performance difference for people on older phones that don't have, for example, the rural Band 71 on T-Mobile or speedy 4x4 MIMO on Sprint. Actual benchmarks between the S9 and S9+ come out pretty much the same, but they don't tell quite the whole performance story.
