Microsoft upgrades Surface Book with Core-i7 processor for better performance, battery-life

Microsoft has just launched the upgraded Surface Book i7 packing more powerful internals with better battery life.

The new Surface Book is powered by Intel's top of the line Core-i7 processor. This coupled with a powerful GPU, Microsoft claims twice the graphics performance of the previous-gen Surface Book and thrice that of the MacBook Pro.

The 13.5-inch 2-in-1 has all new thermals to keep it working cooler with the addition of a second fan and hyperbaric cooling. With newer internals, battery life has also seen a significant jump by about 30 percent and according to Microsoft, the Surface Book i7 can last up to 16 hours on a single charge. Just like the previous Surface Book, you can detach the display portion which works like a tablet with support for the Surface Pen.

The new laptop will be going on pre-order today starting at $2399 and ship in November. The previous-gen Surface Book will remain in stores along with the Surface Pro tablets which haven't seen an upgrade yet.
