The Surface Pro 4 is the fourth-generation Surface-series 2-in-1 detachable, designed, developed, marketed, and produced by Microsoft. The Surface Pro 4 was announced on October 6, 2015 alongside the Surface Book. In the U.S. and Canada, the Surface Pro 4 was released on October 26, 2015.
The Surface Pro 4 is an update over its predecessor, featuring Skylake CPUs, more RAM and SSD options and a 12.3-inch display with a greater resolution. At the same time, the device is compatible with most of its predecessor's accessories.
The Surface Pro 4 was announced on October 6, 2015 alongside the Surface Book. Both devices were available for pre-order the following day and available for customers beginning on October 26, 2015.
The device initially exhibited failure to sleep properly, which drained the battery very quickly. Microsoft subsequently developed a fix that was made available on February 17, 2016.
The Surface Pro 4 is the same size as the Surface Pro 3, but has a thinner screen bezel which allows for a display of a slightly greater size of 12.3 inches (31 cm). The screen resolution is also greater than the Surface Pro 3's, at 2736x1824 at 267 PPI, with the same aspect ratio of 3:2 and 10-point multi-touch. The chassis is 0.03 inches (0.76 mm) thinner and 0.03 pounds (14 g) lighter than the Surface Pro 3.
The cooling system of the 2-in-1 has been redesigned and dubbed hybrid liquid cooling system. It includes heat pipes with a flowing liquid, which is meant to avoid the use of the internal fan when the device is used for less demanding tasks such as web browsing.
All Surface Pro 4 models feature 6th-generation Skylake Intel Core processors—m3, i5 or i7—which are more powerful and run cooler over its Intel Core Haswell predecessors found in the Surface Pro 3 and 2. The maximum clock rate of the most powerful CPU option (i7-6650U) is also greater at 2.2 GHz, with up to 3.4 GHz in the Turbo Boost mode. The m3-powered model is completely fanless.
