The 'brushed onyx' Dell XPS 15 2-in-1 (9575) is a monolithic beauty worth the extra $50

The XPS 15 2-in-1 9575 (see our full review) is one of the more fascinating laptops to be released this year. Taking the performance of the original XPS 15 (9560) and merging it with a 2-in-1 form factor yields a PC with more functionality but retains that 4K InfinityEdge display.

Tricky to order, but a gorgeous conversion

As mentioned in our review Dell has an all-black version of the 9575, but you can only order it online and one configuration. That setup brings the powerful Core i7-8705G with AMD Radeon graphics, 16GB of DDR4 RAM, and the striking 4K Ultra HD (3840 x 2160) InfinityEdge Anti-Reflective touch display. You still do get a choice for storage which runs from 256GB to 2TB options.

Choosing brushed onyx under the configuration versus the standard and familiar silver will tack on another $50 and a few days for manufacturing, but if you want something different, it's worth it.

The onyx color scheme involves three components including the top and bottom metal covers and the hinges, which go from silver to black to match. Its only on the sides can you see a sliver of silver, which gives a subtle dual-tone look.

Even the embossed Dell logo is now shiny black giving a muted appearance except when it catches some light to reflect. More details are found in the all-black hex screws on the bottom versus the matching silver ones found in the original color scheme.

As the name implies, the metal used is brushed versus the standard flat silver design giving the 9575 some texture. Being black, it also shows oils more than the silver, so you will need to wipe it down to keep it pristine occasionally.

Opening the onyx laptop reveals the same soft-touch carbon fiber design found with the silver option. Otherwise, everything else is the same between it and its silver XPS brethren.

Dell testing varying color options

It's not clear why Dell is only offering the XPS 15 2-in-1 (9575) in brushed onyx.

The current XPS 13 (9370) and regular XPS 15 9570 (updated for 2018) do not offer this possibility. The XPS 15 9570 was initially shown to press in black, but Frank Azor, VP General Manager of Alienware, Gaming & XPS at Dell has confirmed multiple times on Twitter that they scraped the choice for unspecified reasons.

Dell has been experimenting with different color schemes over the years first with gold, then rose gold for the XPS 13, then an outstanding white and gold version for this year.

The company is interested in expanding color selection for consumers but it is taking a very conservative approach trying to balance demand with costs and production constraints. For instance, the brushed-onyx XPS 15 2-in-1 (9575) is not even advertised as an option on Dell's site. You must choose the last SKU, which starts at $1,999.99, to even see the selection during configuration. That makes the choice more of a last-minute surprise for consumers. (You can also buy it direct at Best Buy as well).

Regardless of Dell's quirks if you are up to getting the XPS 15 2-in-1 (9575) with an i7 processor and 4K display you should certainly consider brushed onyx. Dell did out a fantastic job with the design and while you can always put a decal over the silver model this black brushed metal look and feel is the way to go if you want something that bucks the familiar look of Dell's XPS line.

  • I bought this at a Best Buy with a 10% off birthday coupon. Definitely worth it, although the 256GB NVMe drive is a bit small. Fortunately I had a spare 1TB SSD so I could swap it out. Upgrading the SSD was pretty simple, which is why I really appreciate that Dell still allows this on the XPS line. A 15" 2-in-1 can be a bit clunky in tablet mode, but I like the option (and why I replaced my 9560 with this model). Also, the 4 lane PCIe makes using an eGPU fantastic (the 9560 only had 2).
  • 2 thousand
  • The Ram is soldered? Deal breaker
  • If you want a very similar machine with upgradable RAM check out the hp Spectre. It wasn't a deal breaker for me, but the upgradable RAM was definitely a point in the Spectre's favour when I was comparing the two.
  • Agree! Dell's lack of transparency in RAM options wasted me lots of time
  • I find often Dell's discussions by users at reddit, forum, are unclear when come to Ram upgrade, NO transparent discussion on max RAM support, RAM slot, which one is soldered, using confusing jargon "on board"
    , not consumer friendly descriptions
  • It makes No sense to me that for notebooks that come with 6 cores, we have no corresponding increase in RAM capacity discussions! We need discussion when will 32GB single ram chip come! What limit the existing notebooks with 2 Ram slots to install 2x 32 GB Ram? Cpu?, Bios?
  • Very pretty... Much nicer than the silver. Doesn't have me regretting my Spectre though.
  • Just to clarify, Dell to me is first to bring customizable 6 core notebooks (Full HD vs UHD) that are not only thin but high performance. I need 4 channels eGPU, possibility to go 64GB Ram in future, these unique needs lead me to the blind spot of DELL notebook communication. I could not imagine that I could not get clear answers when come to memory, wasted lots of time. Lenovo workstations seems to be the next best thing - waiting for 6 core using e.g. i7-8750 instead of Xeon 6 cores
  • Multi cores beyond 4 e.g. 6 or more for notebook makes sense NOT just for gaming, but for developers that need to persue microservice-based compute intensive Intelligent Edge computing (Azure IoT edge)
  • Love the black one. I wish they made the xps 13 2 in 1 in white and rose gold as well. I would have the wifey one in a hot second, and myself the black 15 2 in 1.
  • Wish they would've had this for early birds who ordered within days of release! 🙄
  • The brushed oynx is available for the Dell Precision 5530 which is the business version of the XPS 15. At launch they had their inventory system misconfigured so after waiting 12 days they had to cancel my order because it was registered as 'black' instead of 'oynx' (which isn't even a valid part) in their system and apparently they aren't smart enough to modify 'black' back to 'oynx'. So I had to completely cancel and reorder and still waiting...
  • I would have just ordered the "black" one. Onyx IS a black.
  • There wasn't a black one to choose. It never existed. The only options on their website were, and remain silver or brushed onyx. It was the configuration in their actual inventory system that was broken (the mapping from front end choices to internal part numbers). Which makes it even more frustrating they couldn't just fix it. Turns out they didn't even have it in stock which added another 1-2 weeks delay.
