Microsoft is expected to launch the Surface Book 3 in a matter of weeks and a new leak suggests it will offer a major spec upgrade under the hood. 

The leak, courtesy of tipster Roland Quandt, all but confirms that the Surface Book 3 will feature Intel 10th-generation Comet Lake processors, with the 13-inch model and 15-inch variants set to pack Core i5-10210U and Core i7-10510U CPUs, respectively.
