The Dell XPS 12 is an actual Ultrabook that doubles as a tablet. Our test model has an Intel Core i7 3517U, a dual-core processor with HyperThreading running at 1.9 GHz and a Turbo of 3.0 GHz. The chip has 4 MB cache memory and it's a fast, energy-efficient processor. The TDP is only 17 watts. Like the other mobile Intel Core processors in the Ivy Bridge generation this model comes with Intel HD Graphics 4000 integrated graphics.
The 8 GB DDR3 RAM is soldered to the PCB. The SSD het is an mSATA PM830 with 256 GB of storage. A good size, in our opinion. WiFi is provided by an Intel Centrino 6235 WiFi adapter that can achieve 300 Mbit/s on both bands. It's a good adapter that also provides Bluetooth 4.0. Connectors consist of two USB 3.0 ports, a memory card reader and a Mini DisplayPort.
The Mini DisplayPort only supports monitors with resolutions up to Full HD. The screen on the XPS 12 itself is an excellent Full HD IPS screen with viewing angles. Rotating the screen to and from laptop and tablet modes works straight-forward and well. When you compare its weight to a conventional tablet, the 1.51 kg is a lot, but that does include a very good keyboard with large touchpad. On the sides you'll find the power button, a battery indicator, and a button that prevent the display from rotating when you tilt the laptop. The build quality is pretty solid.
