Microsoft Surface Pro 3 review: specifications

The Surface Pro 3 comes in a wide variety of specifications. You can choose from Core i3, Core i5 and Core i7 CPUs, as well as a spectrum of SSD capacities ranging from 64GB right up to 512GB. Pricing varies dramatically as a result, with the low-end model starting at a very tempting £639. We’d avoid this one, though: its Core i3 CPU and 4GB of RAM may do everything you need, but a 64GB SSD is too tiny these days.
A slightly better bet is the £849 version, which gets you a Core i5, 4GB of RAM and a 128GB SSD, but ideally we’d pick the 256GB model, which also doubles the RAM, at £1,109. If nothing but the best will do, you’ll have to dig deep: the Core i7 versions are both equipped with 8GB of RAM, and the 256GB or 512GB SSD options come in at £1,339 and £1,649 respectively. Bear in mind that none of these prices include the Type Cover, which adds another £110 on top.

Microsoft Surface Pro 3 review: design

The Surface Pro 3 makes a great first impression – it’s exactly what we’ve come to expect from Microsoft hardware. The clean, unfussy design oozes luxury, and while we prefer the moody, all-black exterior of the Surface Pro 2, there is something rather alluring about the Surface Pro 3. Light grey metal reaches all around the back and along the tapered edges, and a slight sparkle shimmers under the matte finish.
And while the the Surface Pro 3 is substantially wider and taller than what’s come before, Microsoft has used the extra surface area to spread the components more thinly and slash the overall weight – the chassis now measures a dainty 9.1mm thick and weighs 800g.
The 12in, 2,160 x 1,440 screen (protected by a glossy panel of Gorilla Glass 3) is a big step up from the 10.6in, 1,920 x 1,080 panels of previous Pro generations. It’s also a different shape, forsaking the Surface Pro 2’s widescreen 16:9 format in favour of a 3:2 ratio. This may not sound like a revolutionary change, but the ergonomic impact is huge. In laptop mode, the display’s extra height brings back happy memories of 4:3, square-screened laptops from the 1990s; held vertically in tablet mode, with the Surface Pen in hand, the extra width gives the feel of a slightly shrunken A4 page. No matter how you use it, the Surface Pro 3 feels like a more natural fit than previous models.

Microsoft Surface Pro 3 review: features

Microsoft has made a few other tweaks here and there, too. The Surface Pro 3’s power connector is another thing that has been redesigned, from the press-on design much like Apple’s Magsafe to a neater, spade-like connector that’s far less prone to being yanked or knocked out.
In previous versions, the Surface Pen could be stored by clipping it into the magnetic power socket. That wasn't ideal, since you couldn't clip the pen in and charge the tablet at the same time. Now, you can stow the pen while the tablet is charging, with concealed magnets allowing you to attach the pen to anywhere on the edge of the tablet.
It still isn't the ideal solution, though, because the attachment isn't strong enough to survive being jostled around in a bag without it being knocked off. Annoyingly, there remains no slot in the edge of the Surface Pro 3's chassis. However, Microsoft includes a small loop of fabric which attaches to the Type Cover, so you can stow the pen there.

Microsoft Surface Pro 3 review: battery life

The Surface Pro 3’s battery life strides past its predecessors. With the screen dimmed to 75cd/m2 and Wi-Fi switched off, our light-use test saw the Surface Pro 3 survive a 10hrs 33mins. Dialling the screen brightness up to maximum and pushing the Core i5 CPU flat-out with our looping Cinebench test saw that figure drop dramatically, but even here the Surface Pro 3 acquitted itself well; it lasted 2hrs 31mins before expiring. In normal usage, we had no problem getting through a full working day of word processing, accessing email and watching the occasional video on YouTube before we needed to reach for the mains charger.
