Due to the improvements Microsoft made to cooling, as well as enhancements with Skylake, the Surface Pro 4 has throttling in check, and that carries through to the Surface Book as well. We’ve already taken a look at what Skylake can bring to the tablet in terms of performance with the Surface Pro 4. This should be plenty to handle virtualization of small workloads, and with the Surface Book coming with Windows 10 Pro, Hyper-V is an option. Memory is dual-channel LPDDR3-1866 that is soldered into the top half of the unit. The Surface Book can be had with up to 16 GB of memory, which should be plenty for most tasks that are done on an Ultrabook. Both have the same Intel HD Graphics 520, although the i7 has a maximum GPU frequency of 1.05 GHz versus 1.0 GHz on the i5.

The i7 bumps the base frequency to 2.6 GHz, and the turbo to 3.4 GHz, which is a 13% increase in turbo.

The i5 is a dual-core processor, with a base frequency of 2.4 GHz and a turbo frequency of 3 GHz, and it has 3 MB of cache available. The base model is an Intel Core i5-6300U, and the top end model moves to a Core i7-6600U. The Surface Book comes with just two CPU options.
