The PC industry has introduced some remarkably exciting designs over the last five years or so. Some of those designs, such as the thin-bezel laptop, have been adopted by almost all players in the industry. Microsoft has certainly been an innovator in the space as well, and the Surface Pro series has become the baseline for an entire category that did not exist in any volume before their launch.

But almost certainly, one of the quirkiest designs to come out of the Surface group has been the Surface Book. First launched in 2015, the Surface Book took an unusual approach to convertible laptops, incorporating an electromechanically detachable screen, and putting processors in both halves of the laptop. The original Surface Book was succeeded by the Surface Book 2 in 2017, and recently Microsoft launched the third generation of their most powerful notebook computer.

With Surface Book 2, Microsoft first introduced the 15-inch version of the notebook, and for 2020, the company is continuing to offer both 13.5-inch and 15-inch models. The electromechanically detachable tablet portion is certainly the highlight feature, and one which the entire design hinges on, pun intended. Microsoft’s Dynamic Fulcrum hinge, which expands the footprint of the base as the laptop is opened, is what provides the Surface Book with its very unique look and feel. Fittingly, for Surface Book 3, Microsoft has opted to keep chassis virtually identical to its predecessor.

Instead the Surface Book 3 is all about the internal upgrades, and they are all significant. The new Book gets an infusion of Intel's Sunny Cove CPU architecture in the form of their newest Ice Lake platform. Built on the company's 10 nm process, it is the first major architectural change since 2015's Skylake, and brings with it more performance, better power management, and a much-improved iGPU. Microsoft has also included the latest NVIDIA GPUs targeting laptops in 2020, with the smaller 13.5-inch Surface Book 3 offering an optional GeForce GTX 1650 Max-Q, while the larger 15-inch model sports the GeForce GTX 1660 Ti Max-Q, both of which are nice steps up in performance over the previous generation's GTX 1050, and GTX 1060 offerings. Also in a first for Surface, the new Book 3 is also optionally available with a NVIDIA Quadro RTX 3000, one of the company's professional-focused GPUs.

The move to Ice Lake also means that for the first time, the Surface Book 3 is now available with up to 32 GB of LPDDR4X RAM, double the maximum capacity versus the previous generation. The 16 GB limit was a function of previous Intel laptop CPUs only supporting LPDDR3, and for a laptop that competes against powerful opponents, this is an important addition.

Although Microsoft still seems reluctant to include Thunderbolt 3 support, they did add a USB Type-C connector on the previous Surface Book 2. That port is now upgraded to USB 3.2 Gen 2, as are the Type-A ports. The Surface Connect charging / docking connector also gets a substantial upgrade as well, and now finally allows two UHD 60 Hz display connections via the new Surface Dock.

As for wireless connectivity, Microsoft if finally moving away from Marvell network adapters as well. As a result, the Surface Book 3 goes all-Intel, using the company's AX201 adapter with Wi-Fi 6.

Past this, the Surface Book 3 sees a relatively minor refresh for 2020, with no cosmetic changes, but certainly welcome changes under the hood. When the Surface Book first launched, it was one of the most interesting laptops on the market. Now, five years later, let us see how that design holds up with some fresh internals.

    Thanks Brett! Too bad that "refreshing dip into Ice Lake" requires such a deep dive into ones bank account! I really like the design, but a more affordable version would make the Surface Book form factor a lot more compelling.

    I mean, it's a premium device. Sure they could've made it out of plastic and sourced bargain components, but then it wouldn't be a Surface. It wouldn't even be a decent laptop. Besides the Book family has always had excellent sales periodically. If you don't like the entry price for quality and innovation, that's your choice, but making snarky comments about it isn't compelling at all.

    lmfao, quality and innovation. The SP series has stagnated so much people are calling the SP7 a "SP4.99", nor is it known for its reliability or build quality. The XPS 13 2-in-1 has comparable (arguably better) build quality, a much bigger battery, a CPU that boosts far better(hardly throttles while SP7 throttles 30%), and its price is still about a tier below the spec-matched SP7 accounting for the pricing and SP7's mandatory keyboard and pen purchases(both included in the XPS, keyboard obviously, but the stylus also comes bundled). Better yet, it's easy to come across factory refurbished XPS13 that come with extended warranty, but not SP7, if they even sell those at all.

    ...and the XPS doesn't detach at all to a straight tablet, double the overall weight, fans, etc. iPads haven't changed much in 5 years. Laptops are still clamshells. And your "minor" spec bumps include doubling cores or threads (or both), WiFi 6, Intel ax adapters, USB - C, 50% better graphics output, instant on.... Etc, etc.... Yes, DEFINITELY NOT EXACTLY WHAT SURFACE FANS HAVE BEEN REQUESTING. How dare Microsoft listen to their customers!
  • ArcadeEngineer - Thursday, June 4, 2020 - link

    Why are we still paying a big price for 'innovation' in a product that's only had spec bumps in four years?
  • Deicidium369 - Friday, June 5, 2020 - link

    has the laptop surface been out for 4 years?
  • Spunjji - Thursday, June 4, 2020 - link

    You're pounding on the concept of "premium = expensive" to avoid discussing the fact that the design is no longer innovative, has been plagued by performance, stability and driver problems throughout its existence, and - as others have noted - you can get equivalent or better quality for less.

    A price drop now that they've presumably amortised the costs of the design would make any and/or all of those concerns more palatable.
  • PeachNCream - Thursday, June 4, 2020 - link

    Agreed that the hardware is interesting, but the price is quite high. As always. someone or some company will make purchases, but for the rest of us that like seeing their net worth go up rather than own status symbol hardware, there are alternatives.
  • Deicidium369 - Friday, June 5, 2020 - link

    those two are not mutually exclusive
  • PeachNCream - Friday, June 5, 2020 - link

    You have absolutely no idea and that much is painfully obvious from your comments.
