The Dell XPS 15 9550 Review: Infinity Edge Lineup Expands
by Brett Howse on March 4, 2016 8:00 AM ESTFinal Words
After everything we've seen so far, what is there to say about the XPS 15? As a pure exercise in style, mimicking the look and feel of the XPS 13 was definitely the right way to go. The same Infinity Edge display allows Dell to squeeze a 15-inch notebook into the space that most 14-inch models take up. The aluminum outside feels great in the hand, but the contrasting dark carbon fibre weave on the keyboard deck makes the keys easier to read, and it also does a better job resisting fingerprints. The soft touch coating makes typing on the XPS 15 very comfortable.
XPS 15 Compared to 15.6-inch Lenovo Y700
The keyboard is roughly (if not exactly) the same as the XPS 13 keyboard, which I liked. The 1.3 mm of travel is kind of shallow for a laptop this large, but overall it is pretty good. There are better keyboards around, but it would not take long to get used to typing on the XPS 15. The trackpad is excellent, with plenty of room to work, and nice smooth scrolling. The Microsoft Precision Touchpad drivers lack some of the customizability of other trackpad drivers, but the gestures available are enough for what I need.
Performance is very good, thanks to a quad-core Skylake processor and a NVIDIA GTX 960M graphics card. This isn’t a dedicated gaming system, but the GPU can hold its own and even allow you to play modern games as long as you are OK turning the graphics down a bit. The CPU performance is strong, although as with the Lenovo Y700, the Skylake quad-core didn’t bring a big jump in performance over Broadwell.
The display shipped on the review unit is the 3840x2160 UHD panel with support for the Adobe RGB color space, but the wider gamut can't make up for the disappointing accuracy out of the box. Once calibrated though, this display can hold its own with pretty much anything out there. Text is very crisp, and colors are very vibrant. It’s a shame that there’s not an easier way to use Adobe RGB, but with more devices starting to support this color space perhaps Windows will work on how it deals with different gamuts. We can hope.
The downside of the over 8 million pixels though is the less than amazing battery life. With a large 84 Wh battery, I was hoping for more than 7.5 hours on our light test, but that wasn’t the case. The efficiency is not fantastic, and it is also hindered by LED backlighting that supports a higher gamut, although we did run our testing on sRGB mode. Overall battery life isn’t much different than the XPS 15 9530 that we tested a while back, despite the IGZO display and latest generation processor. It’s hard to get around driving light through that many pixels. The 1920x1080 IPS panel offered in the base model would certainly help here, though not having tested that model it's hard to say just how much it would help.
Dell didn’t load the XPS 15 down with too much extra software either, which is nice. The Dell PremierColor application is great though, and being able to make improvements to the built in Windows Snap assist is a good move. Much of the time I’m not interested in extra software, but if an OEM can improve upon something that is built in, it’s hard to argue with them adding it in.
Overall, the XPS 15 is one of the sleekest 15-inch laptops on the market. If I was looking to purchase something of this size, the XPS 15 would be near the top of my list, thanks to the excellent build quality, great design, and compact size. When you work it, it does get loud, but the combination of good qualities in the XPS 15 are hard to ignore.

We've checked, and there's only a single drive (and not a RAID device) present in the Windows device manager.Soac - Wednesday, March 9, 2016 - link
I don`t think I have explained correctly. The Laptop came setup in RAID mode on the BIOS, from the forums I saw that it happened to everyone, and yes this is for the 1 single drive 512 samsung m.2. Hence why I said it didn`t make sense. However, if you change the BIOS setting to AHCI the read speeds go up to 1.7Gbps.-----------------------------------------------------------------------

Funny enough, someone was saying that in RAID mode the drive felt faster... so it would be cool if you could test it.

Would be interesting to see how it fares at gaming vs amd's carrizo notebooks.iks - Sunday, March 6, 2016 - link
While this is surely a great piece of tech, with a superb screen, capable hardware, and decent, cooling I still wonder, what is the target audience of this and other similar devices? Have the guys over at Dell and other companies actually tried to do productive work that involves a lot of typing on this so-called "keyboard"? Especially programming? Using impossible to hit buttons with no proper spacing, a short F row, minuscule arrows and no dedicated page up / page down / home / end. Sorry, but a keyboard like that is just dumb, and a torture to use.nerd1 - Sunday, March 6, 2016 - link
Say that to millions of mac users. Apple's DESKTOP keyboard is even worse than this.BPB - Monday, March 7, 2016 - link
I am a developer, and I use a company issued Dell at work (decent specs). The keyboard doesn't matter to me since I dock it at work. At home I leave it closed and plug a monitor/keyboard/mouse into it. So why should I care? I do occasionally use it by itself, but I don't mind since it's not very often. I guess what I'm saying is, how many developers use a notebook without plugging in peripherals?iks - Thursday, March 10, 2016 - link
Well, I'm learning to use Vim to overcome button limitations on the different keyboards I may get to work on in future. People work on 60% boards after all.As far as plugging peripherals in / out, aren't you afraid of the ports coming loose over time?

I wanted to point out that the laptop on this article has different materials depending on if you get the 1080p version vs the 4k version.The 1080p version has a lot more plastic vs the 4k one.

1080p version lacks the glossy glass (which I hate), but it is identical elsewhere.rstuart - Monday, March 7, 2016 - link
I own one of these, but I run Linux. Typical Linux issues - if enable the NVidia card it doesn't boot, and it will be because NVidia hasn't released drivers for it yet. I'm mostly a command line user, so that doesn't worry me overly. The Intel drivers causing the kernel to crash 2 out of 3 boots on the other hand drove me nuts. The latest kernel has fixed that thank god, so it's rock solid now. I was surprised to read people running Windows are having the similar issues - here I was putting it down to Intel's poor support for Linux. It's more of a case of Intel not having good drivers, at all, on anything. Be patient, and be forgiving of Dell - it's Intel's problem, not Dell's.Apart from the display, it works extraordinarily well out of the box. As a Linux user, this is not something I'm used to. On the down side, there is not much in the box as Dell hasn't got their act together yet accessories - mostly because of the change to USB-C.
The one thing I do question myself about is going with the UHD display. It is gorgeous. But according to Dell the HD display roughly doubles the battery life, and in reality eye candy fade but not having to worry about charging during the day would have been appreciated for a long, long time.
One other feature not mentioned in the review is everything (battery, WiFi card, DIMM's, HDD/SSD, fans for cleaning) is accessible with the removal of 8 or so easy to find screws on the back. Unlike some other makes, Dell laptops have been getting better in this regard over the years.
