The Dell XPS displays the world's top performance when examining SSD read and write transfered speeds, although optimized, but that isn't close to telling the whole story. Dell tied this performance in with Intel's 6th generation i7-6550U CPU, 8 or 16GB of 1866Mhz RAM, Intel Iris 540 HD Graphics, along with Dell's 13.3? QHD+ (3200×1800) Infinity Edge Touch Display. The Dell XPS 13 isn't just the best ultrabook available today, it's the best of everything. It truly is and it is great to be back Dell!
