XPS 12 XPS 12 (9Q23) The XPS 12 is a convertible laptop. The convertible mirrors the general aesthetic of the Dell XPS 13 ultrabook and other models in the XPS lineup, although the hybrid swaps out its predecessors' aluminum look for a carbon-fiber exterior. The lid and exterior edge are framed by a machined aluminum edge, while the interior consists of a magnesium-alloy palm rest coated in matte black paint. The Dell XPS 12's body was made with a fingerprint-resisting coating. It possesses a hinged, flip-screen LCD. Applying a push to the top of the screen frees the 12.5 inches, 1920×1080 resolution, 400-nit brightness display from the magnetic locks that hold it in place. The convertible's 1.7 GHz Core i5-3317U processor sports Intel HD Graphics 4000 integrated graphics, which combine with 4 GiB of RAM and a 128 GB solid-state drive and Core i5 processor, but ups the memory to 8 GiB and the storage to 256 GB. Some models configuration includes the Core i7 processor, 8 GiB of RAM, and the 256 GB SSD. XPS 12 (9Q33) In July 2013, Dell released its XPS 12 with Intel Haswell (4th Generation) processor.
