Microsoft's Surface Pro 4 was announced during the Windows 10 Devices event in New York City on October 6th, 2015. It features a full array of 6th generation Intel Core m3, i5, and i7 processor models, with 4GB, 8GB, and 16GB of RAM configurations, as well as up to a 1TB of storage.
The new Surface Pro 4 is thinner, down from 9.1mm to 8.4mm. It is also marginally lighter, starting 1.69 lbs (766g) for the M3 model, and 1.73 lbs (786g) for the i5 and i7 models.
The Surface Pro 4 features a larger 12.3-inch display with a higher 2736 x 1824 resolution (267 PPI) than its predecessor. Like all the current generation Surface devices, it carries a 3:2 aspect ratio. Its other dimensions remain unchanged. As such, there is noticeably less bezel on the sides of the screen than before. It’s also worth noting that the new device does not have a Start button.
