We all know Microsoft Surface Book can be bought with a discrete GPU. Microsoft has only mentioned that it is a NVIDIA GeForce Graphics Processor and they didn’t reveal any technical specifications of it. Microsoft didn’t announce the model name of the GeForce processor as they have built a custom GPU for Surface Book working with NVIDIA. We have confirmed that Surface Book features a Maxwell architecture-powered GeForce GPU with 1GB of video memory. I think this custom GPU will be more or less equal to GeForce GTX 950M in terms of power and performance.

Maxwell is NVIDIA’s next-generation architecture for CUDA compute applications. Maxwell introduces an all-new design for the Streaming Multiprocessor (SM) that dramatically improves energy efficiency. Improvements to control logic partitioning, workload balancing, clock-gating granularity, compiler-based scheduling, number of instructions issued per clock cycle, and many other enhancements allow the Maxwell SM (also called SMM) to far exceed Kepler SMX efficiency.

When Surface team does Reddit AMA next week, I guess we will come to know more about it.

Surface Book is now available for pre-order from Amazon and Microsoft Store. Find links below.
