Dell XPS 15 vs. HP Spectre x360 15

15-inch laptops come with extra power, but which of these wields it better?

If you’re looking for a highly portable laptop, you’ll likely limit your search to 13-inch models. If you’re looking for more power, though, you’ll probably be taking a look at 15-inch laptops. Perhaps the best example is the Dell XPS 15, a popular laptop that packs powerful components into a relatively small chassis thanks to relatively tiny display bezels.

Until now, you were mostly limited to traditional clamshell machines rather than the more flexible 2-in-1 form factor if performance was your primary need. That’s no longer true, with HP’s Spectre x360 15 adopting the same CPU and GPU as the XPS 15. Does this large 2-in-1 have what it takes to compete with Dell’s industry leader?

Design

We’ll be blunt: The Spectre x360 15 is the more striking laptop. HP calls this the “gem-cut” version, and that’s for a good reason. Every edge — along the lid, the chassis, even the keyboard deck — is chiseled at angles that resemble a fine jewel. A new, more exciting Poseidon Blue blue color joins the more subdued Dark Ash Silver to make for a truly gorgeous design. The XPS 15 is good-looking as well, with a more conservative black, silver, and carbon fiber aesthetic that’s likely better suited to a conference room.

Both laptops are built around 15.6-inch displays, but the XPS 15 enjoys much smaller bezels and thus a significantly smaller chassis. It’s 14.06 x 9.27 x 0.66 inches, compared to the Spectre x360 15 at 14.22 inches x 9.84 x 0.76 inches. The Dell is also lighter at 4.5 pounds versus 4.81 pounds. Both laptops feel equally robust.

In addition, both enjoy great keyboards with sufficient travel and precise feels — although we prefer the HP’s version for its more springy and slightly deeper mechanism. The XPS 15, though, has a much better touchpad. It’s larger than the Spectre x360’s and it supports Microsoft’s vastly superior Precision Touchpad protocol. HP continues to use Synaptics drivers that aren’t as smooth.

Connectivity is a draw. The Spectre x360 15 has two USB-C with 40 gigabit per second Thunderbolt 3 support, a single USB-A 3.1 port, and a full-size HDMI port. The XPS 15 is similar, but with two USB-A 3.1 ports, a single USB-C port Thunderbolt 3 support, and a full-size HDMI port. We give the slightest edge to the HP for its additional Thunderbolt 3 port. In addition, the Spectre x360’s combo Intel wireless chip supports Bluetooth 5.0 to the Dell’s Bluetooth 4.2, and the HP also supports two external 5K displays.

The Spectre x360 15 has a more standout design and better connectivity, but the XPS 15 is noticeably smaller.

Performance

Both of these 15-inch laptops live up to the class’s performance promises, using up to the very fast 8th-generation Intel Core i8750H CPU. That’s a six-core, 45-watt processor that churns through high-end productivity and creative tasks. In our benchmarks, the XPS 15 and Spectre x360 15 were close to identical performers. Note that the Spectre x360 15 AMOLED version ships the Core i7-8565U 15-watt CPU, while the XPS 15 will be gaining a faster 9th-gen eight-core Core i9 CPU to with the current 8th-gen six-core option.

The same held true for gaming, where the laptops are again built around the same component. Both use the Nvidia GeForce GTX 1050 Ti Max-Q, a mouthful that designates a competent CPU for 1080p gaming. As long as you’re willing to hold graphical detail to reasonable settings, then you can play most modern games on both the XPS 15 and the Spectre x360 15. Note that the AMOLED version of the Spectre x360 equips the slower Nvidia GeForce GeForce MX150, while the 2019 XPS 15 will be available with the even faster GeForce GTX 1650.

Their displays are where these laptops digress. The Spectre x360 has a very good touch- and pen-enabled 4K (3,840 x 2,160) IPS display that offers good contrast, an average color gamut (73 percent of AdobeRGB) with good accuracy, and just short of our preferred 300 nits of brightness. At this time, there’s no Full HD option, but there is that AMOLED display that’s extremely bright, has class-leading contrast, and the most accurate colors you’ll find on a Windows 10 laptop.

The XPS 15, on the other hand, has a superior 4K touch display (no pen support) that offers significantly better contrast, a wide color gamut (97 percent of AdobeRGB), and excellent accuracy. It’s also brighter at over 400 nits, and there’s a Full HD option that’s also very good if you want to save on battery life.

Each of these 15-inch machines provides the kind of performance you might be looking for in a larger laptop. However, the XPS 15 has a display that’s far better for the very market that will benefit most from its fast performance — creative types editing large photos and editing video.

As we mentioned above, you can choose the Spectre x360 15 with an AMOLED display that rivals Dell’s panel, and the XPS 15 will also be available soon with an OLED display. The equation still favors XPS 15, though, because HP forces you to choose between faster performance or an AMOLED display — Dell will let you have both.

Portability

Neither of these machines is particularly light, at 4.5 pounds or heavier. And while the XPS 15 is smaller, both will take up some room in your backpack.

That makes battery life a more important consideration. Dell packed a whopping 97 watt-hours into the XPS 15 while the Spectre x360 has a still-considerable 82 watt-hours. However, you can buy the XPS 15 with a Full HD display, meaning that if you want more longevity then you have that option.

In our testing, the Spectre x360 15 performed very well for a laptop with a 45-watt CPU and a 4K display. It lasted for eight and a half hours in our web browsing test and 12.5 hours in our local video looping test. The AMOLED version performed similarly thanks to its more efficient CPU.

That compares to the Full HD XPS 15 at roughly 10.5 hours browsing the web and 14.5 hours playing our local video. We haven’t tested the 4K XPS 15’s battery life, but it’s possible that the HP would win that battle. Given that Dell will equip its own AMOLED version with less efficient 45-watt processors, the Spectre x360 15 is likely to be the best choice for anyone who wants the highest quality display and the best possible battery life.

You can drop down in display resolution and get better battery life from the XPS 15, but neither is the most portable laptop around.

The XPS 15’s display will be more pleasing to the creative eye

The Spectre x360 starts at $1,600 for a Core i7-8750H, 16GB of RAM, and a 256GB PCIe solid-state drive (SSD), and maxes out at $2,430 with a 2TB SSD. All versions currently come with a 4K display, either IPS or AMOLED.

The XPS 15 starts out at a significantly lower $1,000 for a Core i5-8300H, 8GB of RAM, a 1TB hard disk drive (HDD), and a 56 watt-hour battery. And you can spend as much as $2,900 for a crazy-fast Core i9-8950H, 32GB of RAM, a 1TB SSD, GTX 1050 Ti, a 4K display, and the full 97 watt-hours of battery.

The Spectre x360 15 is the fastest 2-in-1 we’ve tested, and equal to the XPS 15 as long as you choose the “power” version. But Dell’s choice of a far more colorful and accurate display to go with the fastest components means it’s the better choice for creative types who might actually need all that power.
