https://wccftech.com/microsoft-surface-book-3-gpu-options-gtx-1660-ti-quadro-options/ > Just yesterday, we were discussing the screen sizes and other specs of the upcoming Microsoft Surface Book 3, and thanks to fresh details, we’ve come to know more about the GPU side of things. Since we talked about the Surface Book 3 arriving in two display sizes, it’s only logical that there will be different graphics processors present in both versions. > The Surface Book 3 is expected to arrive in the 13.5-inch and 15-inch display size variants. According to Roland Quandt, the smaller 13.5-inch model will be treated to an NVIDIA GeForce GTX 1650 with 4GB of GDDR5, while the bigger one will feature a GTX 1660 Ti with GDDR5 memory. Now there is something strange we noticed about this configuration and we believe you might have noticed it too.
