Microsoft officially unveiled the Surface Book 3 today, successfully succeeding the Surface Book 2 from around two years ago. The software giant promises that the new notebook will deliver up to a 50 percent increase in performance and that it will be available to purchase in two display sizes. One will be a smaller 13.5-inch version while the other will sport a 15-inch screen. While there weren’t any significant design changes made to the new lineup, let us see if the hardware inside the new notebooks is worth it.

Both the 13.5-inch and 15-inch models of the Surface Book 3 will ship with Intel’s 10th-generation processors, but before you get confused, you need to be reminded that both versions will be outfitted with the ‘U’ series ones with a 15W TDP and not the 45W ones found in the 16-inch MacBook Pro. While that is disappointing to see, there are still other things to look forward to. For example, the Surface Book 3 now comes with the option to incorporate powerful GPUs.
