Memory Bandwidth Results Summary: The Dell XPS 13 9350 and Dell XPS 13 9360 both feature 8GB of DDR3 1866MHz memory with 14-17-17-40 timings with a 1T command rate. Since both systems have identical memory solutions we didn’t expect a big performance difference and didn’t get one. The reason the Dell XPS 9360 was faster was due to the higher clock speeds on the Intel Core i7-7500U Kabylake processor.
