We mixed peanut butter and chocolate
Microsoft’s use of a GPU in the base unit also sets up some pretty interesting ramifications for how a laptop could be upgraded down the road. If you bought a Surface Book without the GPU, for instance, and somehow obtained a base unit with the GPU, marrying the Clipboard to either base would work just fine, Microsoft says.
I tried it myself—yes, I got peanut butter in my chocolate. Did it work? Yup. After a few seconds of downloading drivers, it was up and running without even a need to reboot.
One important detail, should you want to try this “upgrade”: You’ll need the bigger power brick too. They may look the same, but the brick for the unit with discrete graphics puts out 60 watts, while the standard brick puts out just 31 watts. Charging with the lower-capacity brick will be slower, or you may find it discharging even when plugged in if the load is heavy enough.
Alas, the company has no plans to sell the base units with just the GPU. It’s an entire package or nothing.
Of course, that’s Microsoft’s position today, but I can see the potential to upgrade the graphics on the Surface Book by simply buying a new base unit with the latest GPU in it.
As this is a Surface, there’s pen support of course
With Microsoft’s purchase of N-Trig over the summer, it’s no surprise the Surface Book uses the same stylus technology as the Surface Pro 3. This time around, it’s much improved, with pressure levels going from 256 in the Surface Pro 3 to 1,024 levels in the Surface Book and Surface Pro 4. There was a lot of griping from early Surface Pro users that losing the 1,024 in the original Pro was a step backward.
The pen still uses a difficult to source AAAA part but you shouldn't have to worry about it for a year or so between uses. Opening it is also a little different. With the Surface Pro 3 you just unscrewed the top. The the new Surface pen you rotate it counter-clockwise a few millimeters and then pull it out.
The good news is the new pen feels great. It features a rubbery nib with optional tips to tailor the feel. Microsoft said it also burned engineering time on a new G5 controller to optimize touch and pen input for the Surface.
I’m admittedly not a heavy pen computing user, but I like them for those times when I need to sign or mark up a document. I compared the Surface Book’s pen input to a laptop with a Synaptics pen, as well as the Surface Pro 3 with its older n-Trig pen. I found the palm rejection to be fairly excellent on the Surface Book, but it couldn’t reject my knuckle-dragging ways. I like VAIO’s solution: Just switch off the touch digitizer by pushing a button.
Parallax, which is certainly better on today’s pen devices, was still a millimeter or so off from the tip of the pen when tilted over. Latency also didn’t feel like a quantum leap over the Surface Pro 3 in my book, but I’m basing this on “feel” rather than any real testing.
The 13.5-inch screen on the Surface Book is a stunner. It’s got a 3:2 aspect ratio with a resolution that’s easy to do the math on: 3,000x2,000. That’s about 6 megapixels.
Microsoft said it’s an IPS panel that uses a “negative photo-aligned liquid oxide display.” That’s a fancy way of saying that during construction of the panels, the layers are carefully aligned to increase contrast and image quality. Televisions have used this technique, and Apple recently celebrated the tech in its iPhone 6 rollout. However, those layers make the screen more prone to reflections than, say, the current MacBook Pro 13.
The display is rated for 100 percent coverage of the sRGB color gamut. It’s also spec’ed to hit a blazing 400 nits in brightness. Our meter agreed, putting our Surface Book sample actually a little brighter.
Ports of call
The Surface Book’s port array includes two USB 3.0 Type A, a miniDisplayPort and an SD card reader. For an Ultrabook, this is pretty typical. The Surface Book gets bonus points for its docking station, which gives you two more DisplayPorts, Gigabit ethernet, four USB 3.0 ports, and analog audio out. This all connects through the Surface power connector.
I’m surprised there’s no support for Intel’s new Thunderbolt 3.0 or USB 3.1 on the Surface Book for higher speed I/O devices. Sure, I’d rather have a pure miniDisplayPort over USB-C but it feels odd not having USB 3.1, at least. Read to find out what the GPU is inside the Surface Book and how it performs.
Microsoft Surface Book
Microsoft's Surface Book reboots what you'll think a laptop should be.
- Tremendous battery life
- Beautiful screen
- Doesn't compromise on laptop use and adds wonderful Clipboard mode
- Rather large and heavy
- Very expensive as you add options on
