The Marvel Wi-Fi hardware was a problem in the past with instability issues for some users. But since Intel is the predominant maker of Wi-Fi 6 laptop chips, it is an excellent move away from Microsoft's previous supplier Marvel. Wi-Fi 6 (ax) is standard these days in most new laptops, so it being here is not remarkable. With Surface Book 3 15-inch, 16GB is now the lowest model, and it is only available in one of the four models, with the other three being 32GB configurations. Surface Book 2 could only be purchased with 16GB of RAM max, but developers and engineers demanded more.

The new 127-watt charger fixes this problem. When maxing out Surface Book 2 for CPU and GPU, say during video gaming, it was possible to drain the battery while plugged into the wall. The larger charger - now at 127 watts versus just 102 previously - may seem minor, but it matters a lot. Intel Wi-Fi 6 + Bluetooth 5.0 (instead of Marvel)
