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.

    In a laptop as thin as this, you need to consider that the last 1.5-2cm of each side is unusable for keyboards due to ports directly under the keyboard bezel. Unless you want a thicker laptop or a keyboard with zero key travel, this would leave you with far too little space for a numpad.

    It is appalling that a computer at that price is a do it yourself project (assemble yourself)!
    Firmware updates back and forth, take it apart to move the mother board so USB and other ports fit into the holes so the connectors can come in!
    Chinese junk, why would Dell put there name on this?

    It seems like you've had a bad experience, would you mind expanding on that? Taking it apart to move the motherboard (which should be very firmly screwed in, after all) seems pretty drastic.

    Just start reading this thread!

    Ouch, that looks bad. Hopefully they get that sorted out pronto, and fix the issue for anyone involved free of charge. That should NOT have passed QC.

    Hi AnandTech, will you be able to confirm what thunderbolt 3 controller does XPS 15 9550 use? It seems to me that i cannot find any x4 link in PCIe configuration with HWINFO64, so i am suspecting that it uses a x2 link for thunderbolt 3. If this is true, then it can only interact with motherboard with a rate up to 20Gbps for PCIe 3.0 x2. I hope i am wrong.

    It would be great if Anandtech would contact Dell, for an explanation of all these problems buyers have experienced with their Dell XPS 15 9550, but it is perhaps too much to ask for?

    The question is, when it is possible to have one that is not faulty (if at all)?

    Can anyone that owns an XPS 15 9550 comment on how long the fans take to return back to idle after playing an intensive game? I've had Dells in the past not be able to reduce fan speed back to idle after gaming. Thanks in advance. Looking into a UHD/i7/16GB/512GB model.
