The Dell XPS 15 9560 Review: Infinity Edge Part Two
 

Near the end of 2015, Dell rolled out their new XPS styling queues, that were so successful on the XPS 13, to its larger sibling, the XPS 15. Thanks to the Infinity Edge display, Dell’s new XPS 15 packed a full 15.6-inch display into a notebook closer to the size of a 14-inch model. Perhaps the size reduction is not quite as dramatic as the XPS 13 when it first launched with the thin-bezel design, but Dell also kept the performance heart of the XPS 15 intact with the change, keeping a quad-core 45-Watt CPU, and NVIDIA GTX 960M graphics.

Dell has since done a revision from that XPS 15 9550 model to the latest 9560 version. The small model number change might signify that this is a small revision. On the exterior that is certainly the case, with the overall XPS 15 design remaining relatively unchanged, but under the hood there are some more impressive changes awaiting.
