![]() ![]() To see how the new Surface Book 3 performs, it was run through our recently updated laptop suite. But the Core i7-1065G7 found as the only option on the 15-inch model is no slouch either. ![]() It would have also been interesting to see them go with the Comet Lake based Core i7-10710U, which offers six cores, since the GPU duties can be fulfilled with the NVIDIA GPU when needed. Microsoft certainly has more experience with Intel's SoCs, so it is not too surprising to see them stick with Ice Lake for this notebook, even though AMD could have offered twice the CPU cores and threads with Ryzen. A couple of years ago, there would be no debate about this at all, but in 2020 there are three viable choices for this notebook. Microsoft has chosen to go with Intel’s latest Ice Lake platform for their CPU option. And if you need even more performance and want to spend even more money, the Quadro RTX 3000 is an even larger GPU, plus it offers the Turing architecture’s RT Cores, which the GeForce GTX does not provide. So despite the less-powerful processor options, if your work is GPU accelerated, this could be an advantage for the Surface Book. The advantage of the Surface Book design though, with two separate thermal loads, is that Microsoft can fit a much larger dGPU in the base, since it does not need to share the thermal capacity with the CPU, and the Surface Book 3 15 ships with the NVIDIA GeForce 1660 Ti in Max-Q configuration. ![]() In CPU bound tasks, this is going to be a disadvantage. ![]() But the larger 15-inch model, as a productivity and performance targeted device, is going to be competing against devices which normally offer a 45-Watt CPU design. On the smaller 13.5-inch, that’s not such a bad thing, since almost all other notebooks in that range also feature 15-Watt platforms. This provides the Book’s unique design feature, though it's a choice that does come with some compromise, as the nature of the device locks Microsoft into the 15-Watt processor options. As with its predecessors, the Surface Book 3 packs the main CPU/SoC, RAM, SSD, wireless controller, and one of its batteries into the display section, serving as a detachable tablet. ![]()
