Dell XPS 15 review: as good as it gets from a 15-inch home or work laptop


Super design, 4K graphics and powerful too

Incredible 4K screen ; Very powerful ; Tidy size for a 15-inch laptop

It loves fingerprints ; Only two USB ports

Dell XPS 15 (2016) review: Pursuing perfection


Laptops can usually be split into one of a few different camps. There are chunky gaming laptops that'll give you back-ache, but can handle running The Witcher 3 like no other. There are super-ultra slim laptops with amazing battery life. Or those fancy...

Very small footprint for a 15-inch laptop, a powerful and versatile machine, great keyboard and trackpad

Not all-day battery life, some odd spec configs, no dedicated SSD in entry-level model

The Dell XPS 15 is an unusual laptop. In the venn diagram of portability, power and generally looking and feeling great, it tries to cover everything. And unless you want something very light or are a turbo-nerd, it absolutely succeeds. Which is a rare...

Dell XPS 15 (Late 2015) review


Dell's superb workstation, gaming and entertainment laptop is not without flaws

Display ; Performance ; Thunderbolt 3 ; Clickpad

Battery life ; Speakers ; Keyboard ; 960M not future-proof

A powerful 15-inch laptop squeezed into a 14-inch sized chassis, the XPS 15 is a great fit for productivity work, gaming and entertainment thanks to its excellent 4K display. Just watch out for its lacklustre battery life, poor speakers and and shallow...

Dell XPS 15 (early 2015) review


This is a top-tier Windows machine that rivals the MacBook Pro

Fantastic 4K screen ; Well-rounded specification ; Stunning exterior design ; High-quality keyboard

Battery life is only middling ; Some fan noise

The XPS 15 has a stunning 4K screen, high-quality design, well-balanced components and a great keyboard – and all of this makes it a worthy rival to the MacBook Pro.

Dell XPS 15 9550 review


The XPS range is where you'll find Dell's most desirable laptops. These aren't practical workstations or budget models. XPS is where Dell's fanciest designs team up with higher-end components. Here's our Dell XPS 15 9550 review

The Dell XPS 15 is a great all-rounder laptop. Come to it expecting superlatives, especially the version tested, and you may come away disappointed. However, it is very versatile indeed.It offers a powerful CPU, a competent discrete graphics card, a...

Dell XPS 15 review


A powerful laptop, but an unresponsive touchpad and disappointing ultra-high resolution screen let it down

Despite being a lovely looking laptop, the Dell XPS 15 just has too many flaws to justify its price. We expect near-perfection at this price, and a laptop with an unresponsive touchpad and a problematic screen just isn't good enough when compared to...

Dell XPS 15 (2016) Review


Dell has been producing some of the most powerful gaming laptops since well before it purchased Alienware almost exactly a decade ago. The original XPS Gen2 was one of the most potent gaming laptops in its day, and the XPS brand has been synonymous...

Excellent battery life.

Faster 15in gaming notebooks are available.

The Dell XPS 15 combines excellent battery life with decent gaming potential into a slim, reasonably light chassis – but the beautiful 4K screen makes for a relatively high price too.

Dell XPS 15 review: A MacBook Pro rival for Windows users


Well-built, thin and light ; Comfortable keyboard ; Powerful performance options ; Beautiful 4K, color-accurate screen option

Short battery life with the 4K display ; Touchpad can be flaky

If you've been searching for a Windows-based alternative to the MacBook Pro, look no further than the Dell XPS 15. For a similar price, it offers comparable horsepower, a thin and light design and a brilliant 4K screen option. The one area where it...

Dell XPS 15 (2015) review


With the best laptop display we've ever tested, Dell's XPS 15 is as gorgeous as it is powerful.

The Dell XPS 15 is a faithful, up-sized rendition of the innovative XPS 13. Like its predecessor, the 15-incher cuts back on size and weight without sacrificing performance. In fact, the XPS 15 is a major leap over the previous model, at least in its...
