It was roughly a year ago that we had a chance to review Dell’s XPS 13, which was the first laptop from Dell to feature the Infinity Edge display. In addition to making the laptop look as much like a bezel-less display as possible, it also let Dell squeeze a 13-inch laptop into a much smaller chassis. The XPS 13 is still, to this day, unparalleled in the PC space in this context. So the obvious question at the time was when or if Dell was going to do the same to the rest of the XPS lineup? That question was answered in October  2015,  when Dell launched the updated XPS 15 with Skylake and Infinity Edge. Just like the XPS 13 before it, the laptop was bezel-less and the larger 15.6-inch model fits into a laptop chassis that would normally house a 14-inch display. Smaller, lighter, and with the same styling as the XPS 13, Dell has the potential to set the bar higher in the larger laptop segment as well.

With the updated chassis also came an update in the internals. Dell moved to Skylake for the 9550 model, with Core i3, i5, and i7 models based on Intel’s H Series chips. The Core i3-6100H is a dual-core 35-Watt CPU, and the Core i5 and i7 are both quad-core 45-Watt processors. The base RAM option is 8 GB of DDR4, and you can order up to 16 GB from Dell, although this laptop does have SODIMM slots so you can add up to 32 GB if needed. Graphics on the Core i3 model is just the base integrated solution, but all other models come with a 2 GB GeForce GTX 960M graphics card, which has 640 CUDA cores, 1096 MHz frequency plus boost, and a 128-bit GDDR5 memory subsystem.

Dell offers two display choices. The standard model is a 1920x1080 15.6-inch model, or you can opt for the $350 upgrade to a 3840x2106 touch display which has a backlight which can cover the Adobe RGB color space.

Dell offers a 500 GB hybrid hard drive as the base offering, and a 1 TB hybrid upgrade, or you can get rid of the spinning disk altogether and choose PCIe based solid state drives, with 256 and 512 GB options. If you elect for an SSD, you also have the option of getting an 84 Wh battery instead of the standard 56 Wh version. The 84 Wh battery takes up the space where the 2.5-inch hard drive would have been, which is a smart idea.

Wireless options are interesting as well. The base model comes with a 2x2 802.11ac wireless card, but the upgraded models feature a 3x3 802.11ac offering, which is rare indeed on a Windows PC. This gives a maximum connection rate of 1.3 Gbps, assuming you have a router that can support 3x3 connections. This should, in theory, give a lot better throughput than the more common 2x2 implementations we see on most notebooks, but this is certainly something we’ll test later on.

We also see Dell continue to support Thunderbolt 3 ports, which is coupled with a USB Type-C connector. This port provides 40 Gbps of bandwidth when in Thunderbolt mode and can be used for various peripherals including Dell’s own Thunderbolt dock which gives a single cable docking solution. The dock adds Gigabit Ethernet, HDMI, two DisplayPort connections, VGA, three USB 3.0 connectors, two USB 2.0 connectors, headset, and even a speaker output. The laptop itself also has two more USB 3.0 ports, HDMI, and a SD card reader.

Overall this is a pretty compelling package. Dell is offering a 15.6-inch notebook which is about the same size as a 14-inch model, but at the same time they’ve found enough space to pack in plenty of performance, along with Thunderbolt 3 and one of the few 3x3 wireless implementation to date.

    Installing linux on latest hardware is generally a nightmare... which distro are you using? Do they now (finally) support switchable graphics and hi-dpi display?
  • cpoole - Monday, March 7, 2016 - link

    not sure about rstuart but I am running ubuntu-gnome 15.10 with kernel 4.4 built from intel DRM nightlies and I have almost 0 problems with the laptop. Hi-dpi works great and if you're running the nvidia proprietary drivers turning the gpu on and off with the nvidia tweak tool is a breeze... although I havent used it for anything other than a cuda demo.
  • nils_ - Tuesday, March 8, 2016 - link

    Switchable graphics do work on a per-program basis but it's a hassle. Makes the NVidia chip pretty much a waste. Everything else is due to Intel being slow to get their drivers into the kernel and distributions running on outdated, sometimes self-maintained kernel versions.

    So yeah it now sucks a bit more than t used to.

    There's a lot of complaints about the photo quality which I get but - why would you use a 4:3 wallpaper as your cover photo on a laptop specifically featuring an ultra small bezel? It's kind of mystifying because then the black fill..... looks like a huge bezel. This is currently the featured article on the front page and it makes something that honestly looks pretty futuristic/cool into what looks like somebody's office computer.

    I stand by my original statement, the readers around here are now more informed than the editorial/review staff. No amount of excuse making will change this. In the past Anand (the person) worked with manufacturers on a regular basis to identify and correct issues like the one pointed out with this machine. We will never hear of a resolution to this problem on this website, unless it is in the comment section. And yes, if you are in the business of reviewing products, it IS your responsibility to investigate the issue...a simple check on the forums and a warning paragraph would have sufficed, you'd think the reviewers would haver a checklist to follow by now lol.

    I really like the infinity display, other than that I could do without the GTX960M (give me Iris Pro instead) and I don't need a touch screen. Would be great to have more BTO options.

    Why put the XPS 13 keyboard in the bigger XPS15?

    This is design laziness from Dell. I have an XPS 13, and miss the proper key layout, but perhaps it wouldn't fit.

    PgUp, PgDn and bigger arrow keys are a must. Look at Lenovo for how to do a laptop keyboard.

    Am I the only one who would want a dGPU-less (but preferably Iris/Iris Pro-powered) version of this? Slightly slimmer (if possible), same battery size, and a QHD display. And external GPU support through TB3, of course.
  • nils_ - Wednesday, March 9, 2016 - link

    nope. I don't need dedicated graphics in a laptop.
  • Valantar - Saturday, March 12, 2016 - link

    Exactly. Dedicated graphics add too much power draw for too little gain outside of humongous gaming "laptops." A good iGPU and the option of external graphics through TB3 (either with a desktop class chassis or a dock/slice/brick style mobile GPU with it's own battery) is all anyone would need in a device like this.
