At Microsoft’s hardware event this week, the company showed off a wide range of new hardware from phones to the brand new Surface Book. The laptop, or more technically a 2-1, has several unique features to it but the one most people seem to be interested in, is the dual-GPU setup that the Book offers.
Here’s how it works, inside the tablet portion of the device, or clipboard as Microsoft calls it, is an Intel Iris setup that works in harmony with the integrated chipset but if you opt for a higher end model, there is a second GPU in the base. This additional GPU, paired with additional batteries in the base, is what helps separate the Book from other devices on the market.
For those that are curious about what this extra GPU adds to the setup, Microsoft tells me that it is a custom NVIDIA GPU designed specifically for Surface Book and is based on the Maxwell architecture. The chip has 1GB GDDR5 memory which should be enough for most activities but for those looking to do serious gaming on this machine, this chip may not offer everything you need. Still, it’s important to wait for the benchmarks to come out before definitively deciding what this GPU can and can’t handle.
For those that are on the fence about if you should splurge for the higher end model with the secondary GPU, hopefully this additional information makes the decision easier for you.
