Dell XPS 15 review: the perfect Windows laptop?

Dell's 15in flagship takes the fight to Apple with a superb and relatively affordable high-performance laptop.

Dell has hit a rich seam of form in recent years. Now, it’s taken the elegant carbon-fibre and metal design of the XPS 13 and again scaled it up to bring the company’s stylish 15in laptop, the Dell XPS 15, into 2017.

Throw in Intel’s latest seventh-generation quad-core processors, Nvidia’s gaming-class graphics and blazingly quick PCIe solid state drives, and the Dell XPS 15 is ready and raring to do serious damage to credit cards across the globe.


If you’ve seen the XPS 13, then you know exactly what to expect here. Over the years, Dell has worked hard behind the scenes to refine the design of its XPS models, and the result is some of the finest Windows devices the world has ever seen.

Squared-off slabs of cool-to-the-touch metal sandwich a thin wedge of carbon fibre; long rubber feet poke through the underside; and the clean, crisp design is all straight-line geometry and subtle curves. Suffice to say, the XPS 15 is a handsome devil. There’s something about the visible weave of the carbon fibre and the fine sheen of the metal that make for a high-end yet understated appearance.

Tilt back the lid, and there are barely a few millimetres of bezel framing the Dell’s 15.6in display. This looks great (we’re big fans of tiny bezels), but it also means the Dell XPS 15 is smaller than laptops with similarly sized displays.

It’s a couple of millimetres thinner and narrower even than the equivalent MacBook Pro, and a more significant 12mm less deep. If you want a larger laptop with the smallest possible footprint, then the XPS 15 emphatically ticks that box. It’s not too heavy, either, at 2kg.

What’s most impressive, though, is that Dell has made a beautiful-looking laptop without compromising on the essentials. The backlit keyboard provides just enough key travel and feedback to make for comfortable typing, with no cramped cursor keys or layout issues to sour the deal, and the touchscreen above feels superbly responsive, with a layer of Gorilla Glass 3 providing a smooth, silky feel for prods and gestures.

Even the buttonless touchpad, often a weak point for Windows devices, is good, and we found myself acclimatising to its solid clicks and range of multi-finger gestures with little in the way of annoyances and frustrations.

Features and connectivity

As ever, though, it’s connectivity that finds itself sacrificed at the altar of slimline loveliness. Dell has equipped the XPS 15 with a pair of USB 3 ports, a USB 3.1 Gen 2 Type-C port (which also doubles as a 40Gbits/sec Thunderbolt 3 connection), an SD card reader, a 3.5mm headset jack and an HDMI 1.4 port.

That’s not particularly generous for a 15in laptop, but it would be sufficient for many people – and while there’s no Ethernet port, Dell has included a blazingly quick 3x3-stream Broadcom 802.11ac Wi-Fi adapter. This means is that, with the right router, you’ll be able to connect at link speeds of up to 1,300Mbits/sec, which is fast by any measure.

Elsewhere, Dell has included a one-touch battery meter – press a button, and five LEDs light up to indicate remaining capacity – but we’re not sure anyone will get excited about the 720p webcam. We wish manufacturers would pony up for decent image sensors on high-end laptops.

Still, we can take solace in the fact that the XPS 15 at least has a decent set of speakers hidden away inside. Crank them up and switch the Waves MaxxAudio Pro app to its Music setting (the default MaxxSense mode tends to distort a little too much for our taste), and the result is better audio quality with music, movie and game soundtracks than most laptops we’ve encountered.


While the entry-level models make do with a Full HD non-touch display, the pricier models in the lineup add a 4K touchscreen to the laptop. Suffice to say, everything looks razor-sharp, and it hits all the right notes.

The glossy layer of Gorilla Glass 4 across the display might not be to everyone’s taste, but it does give images a tremendously vibrant, punchy look. While skulking through the darkened corridors of Metro: Last Light, the Dell’s Full HD display picks out a huge amount of detail while delivering deep, inky black. It’s simply superb.

Brightness rises up to a respectable 365cd/m2, contrast reaches to 1,612:1 and it covers an impressive 91.2% of the Adobe RGB colour gamut. The best news of all, however, is that Dell has done away with the dynamic contrast feature it forced on the XPS 13. Brightness remains stable regardless of what you’re viewing onscreen, which is good news for those looking to use the XPS 15 for reliable photo- and video-editing duties.

The display’s ability to reproduce a huge palette of colours means onscreen colours often look overly intense, which is a common issue with wide-gamut displays, but Dell’s PremierColor app aims to counter that by allowing users to swap between a range of display modes including sRGB, Adobe RGB, Rec 601 (the standard for SD video), Rec 709 (HD video) and Rec 2020 (4K video).

The XPS 15’s default display mode just so happens to be perfectly calibrated for the Adobe RGB spectrum, delivering a superbly low average Delta E of 1.82 – that's fantastic news for anyone working in colour-managed applications such as Photoshop. It’s exceedingly accurate from the moment you take it out of the box.

Next: Performance and verdict


It might not look it, but the XPS 15 is something of a performance heavyweight. Unlike its smaller stablemate, the XPS 15 ups the ante with a seventh-generation (Kaby Lake) Intel Core i7-7700HQ processor across the range, along with dedicated graphics in the guise of Nvidia’s capable GeForce GTX 1050 GPU and superfast PCIe SSDs. Oh, and you have a choice of 8GB, 16GB or 32GB of DDR4 RAM for good measure.

The result is a laptop that feels brutally fast in pretty much every scenario. Press the power button, and Windows 10 is up and running in seconds. This is largely due to the PCIe SSD: with sequential read speeds of over 1,291MB/sec, it’s something of a revelation, and everything feels supremely responsive as a result.

Largely thanks to the quad-core Intel Core i7-7700HQ chip, the XPS 15 produced stunning test results. In our demanding suite of image-processing, video-transcoding and multitasking benchmarks, the XPS 15 skipped through to a very respectable score of 127 – a near perfect score.

On games, the XPS 15 is unusually capable when it comes to 3D gaming. Our current go-to benchmark is Metro: Last Light, and while it’s no walkover, the Dell’s GeForce GTX 1050 and its 4GB of GDDR5 memory are more than capable of doing it justice. Running at Full HD resolution and lowering the detail to Medium provided a silky smooth and if utterly gorgeous-looking experience, sending average framerates well above 60fps. Frankly, it’s hugely impressive that this laptop didn't immediately melt itself to a pile of hot metal and plastic.

Yet more impressive is the fact that the XPS 15 doesn’t cook itself while working flat out. Crucially, we observed no stuttering or throttling at all – the case felt warm to the touch, with a particularly hot area above the keyboard’s function keys, but this is nothing to worry about.

Battery life

All that power-hungry hardware inside the XPS 15 didn’t even take a toll on battery life, either. Dell includes a 56Whr battery with Full HD screen and a 97Wh battery with the more power-hungry 4K screen. We tested the latter and the XPS 15 managed to survive 10 hours 25 minutes in our video-rundown test.

That’s almost twice the longevity than last year’s Skylake-equipped model and would translate to a full day without a recharge for an average business day.


With close to perfection across the board, Dell should be patting itself on the back for delivering yet another top-notch Windows 10 laptop. The XPS 15 is powerful, portable and packed with high-end features. Factor in the genuine gaming capabilities, and we can see the XPS 15 being very popular everywhere from the bedroom to the boardroom.

Considering what’s on offer, the XPS 15 is good value too. Even the entry-level $2,499 model includes the Core i7-7700HQ and GTX 1050, along with a fast 256GB PCIe SSD, 8GB of RAM and Full HD non-touch display.

That’s $1,000 less than the entry-level MacBook Pro 15-inch with roughly similar specs. For $500 less than that MacBook, you’ll get better specs – including a 4K touchscreen and 512GB PCIe SSD – and you can find even better value if you wait for one of Dell's frequent specials.

This is exactly the kind of laptop that manufacturers need to be making if they’re going to take the fight to Apple. It’s fast, gorgeous and good value.

Those who prefer an ultraportable, a hybrid device or MacOS will, of course, look elsewhere. But for everyone who wants regular laptop with a full-size screen and keyboard, this really is the do-it-all Windows laptop we’ve been waiting for.

It’s not overly generous with expansion ports, but otherwise the Dell XPS 15 is close to perfection, with powerful processor and graphics, all-day battery life, excellent display, and light and compact for a 15in laptop. For those looking for regular notebook with a full-size screen and keyboard, this really is the do-it-all Windows laptop we’ve been waiting for.
