When rumors began spreading that Intel was going to collaborate with AMD in the integration of Radeon graphics cards in its processors, it sounded more like a joke than a real project. However, it turned out that the two Californian giants have really shaken their hands and have prepared something big, and the first laptop manufacturer to take advantage of the new chips is another US company – Dell.
XPS 15 9575 2-in-1 is the name of the first model that uses a hybrid Intel/AMD processor. When it comes to the chip, the machine arrives in two options – with either Core i5-8305G or Core i7-8705G. Both models are quad-core and work with a Radeon RX Vega M GL integrated graphics card (also called Radeon RX Vega 870), as the bigger one runs at higher frequencies and has more cache memory.
However, this is not the only intriguing feature of XPS 15 9575 2-in-1. The new series offers an innovative cooling system, great display options, and sleek body.

Dell XPS 15 9575 2-in-1 configurations
What’s in the box?
Opening the box of XPS 15 9575 2-in-1 reveals another box – this time far thinner and more elegant. So thin that there is no room for the Dell Premium Active Pen stylus, which we hoped we’d find inside, considering the laptop price.
In turned out that the stylus is bought separately and its price in the USA is $99. The stylus itself sounds amazing on paper – 4096 pressure levels and 1-year battery life. Overcoming the slight disappointment of its lack, we notice a 130W charging device featuring Type-C port, Type-А to Type-C dongle and some user manuals.
We were pleasantly surprised by the label “100% recycled plastics, 25% from oceans” – PR or not, Dell has put some effort into helping the nature and this is worthy of respect.
We know you wouldn’t otherwise type it, so here is the link.
Design and construction
Dell XPS 15 9575 2-in-1 is the tiniest and thinnest 15.6-inch 2-in-1 laptop in the world. This is a pretty good start to the Design and construction section when it comes to a notebook that can easily be considered a working station. The thickness of XPS 15 9575 2-in-1 is between 9 mm (front) and 16 mm (rear) and its weight starts at 2.0 kg.
The construction itself is extremely tight and robust which is great for two reasons – the first one being the relatively high price of the laptop, and the second – its ability to rotate at 360 degrees and it’s important after 5 years of use to continue getting its job done. It seems that we can trust Dell engineers in this respect given the fact that the construction is a pretty solid mix of aluminum (in the chassis), carbon (in the palm rest area), steel (in the hinges) and Gorilla Glass 4 (in the display).
We have no complaints about the appearance, the model looks amazing – the ultra-thin bezels called “InfinityEdge” by Dell contribute to that.
In addition, the keyboard that Dell calls MagLev is pretty interesting. It looks very much like those in modern MacBook Pro models – very short key travel and tactile feedback. Its construction is based on a butterfly mechanism and magnets that allow long-term reliability that doesn’t wear out.
At the top, on the right side of the keyboard we notice a fingerprint reader which is combined with the Power button. It is convenient and simple to use, but keep in mind it is optional so your configuration may not feature one.
The first thing that will catch your attention while looking at the Dell’s XPS 15 9575 2-in-1 body is the lack of “big” USB Type-A ports. Yes, the model works only with USB Type-C, and as we mentioned at the beginning of the review, there is a dongle available for your Type-A accessories.
On its left side, Dell XPS 15 9575 2-in-1 is equipped with two USB Type-C ports, MicroSD card slot, and a battery indicator button.
The right side incorporates other two USB Type-C ports (support for DisplayPort / HDMI), combo audio jack and Noble Lock slot.
All Type-C ports can be used for charging the laptop.
Dell XPS 15 9575 2-in-1 is equipped with a Full HD IPS touch-sensitive panel with a model number Sharp SHP148E (4xx10-LQ156M1). It has a diagonal of 15.6 inches and a resolution of 1920 x 1080, leading to a 16:9 aspect ratio, pixel pitch of 0.18 х 0.18 mm and a pixel density of 142 ppi, thus making it appear as “Retina” when viewed from at least 60 cm.
The viewing angles are comfortable. We offer images at 45° to evaluate image quality.
The screen of the Dell XPS 15 9575 2-in-1 has an excellent maximum brightness of 410 nits in the middle of the screen and 367 nits as an average for the whole area, with a maximum deviation of 18%. The Correlated Color Temperature on a white screen is 6600K – very close to the optimal for the sRGB standard of 6500K. The average color temperature through the grey scale before profiling is 6800K.
In the illustration below you can see how the display performs from uniformity perspective. In other words the leakage of light from the light source.
Values of dE2000 over 4.0 should not occur, and this parameter is one of the first you should check if you intend to use the laptop for color sensitive work.
The contrast ratio of the panel is very good – 1620:1 (1460:1 after profiling).
To make sure we are on the same page, we would like to give you a little introduction of the sRGB color gamut and the Adobe RGB. To start, there’s the CIE 1976 Uniform Chromaticity Diagram that represents the visible specter of colors by the human eye, giving you a better perception of the color gamut coverage and the color accuracy.
Inside the black triangle, you will see the standard color gamut (sRGB) that is being used by millions of people in HDTV and on the web. As for the Adobe RGB, this is used in professional cameras, monitors etc for printing. Basically, colors inside the black triangle are used by everyone and this is the essential part of the color quality and color accuracy of a mainstream notebook.
Still, we’ve included other color spaces like the famous DCI-P3 standard used by movie studios, as well as the digital UHD Rec.2020 standard. Rec.2020, however, is still a thing of the future and it’s difficult for today’s displays to cover that well. We’ve also included the so-called Michael Pointer gamut, or Pointer’s gamut, which represents the colors that naturally occur around us every day.
The coverage of Dell XPS 15 9575 2-in-1 is shown by the yellow pointed line. Its display covers 95% of the sRGB gamut of sRGB/ITU-R BT.709 (web/HDTV standard) in CIE1976.
Our “Design and Gaming” profile delivers optimal color temperature (6500K) at 140 cd/m2 luminance and sRGB gamma mode.
We tested the accuracy of the display with 24 commonly used colors like light and dark human skin, blue sky, green grass, orange etc. You can check out the results at factory condition and also, with the “Design and Gaming” profile.
Below you can compare the scores of Dell XPS 15 9575 2-in-1 with the default settings (left), and with the “Gaming and Web design” profile (right).
The next figure shows how well the display is able to reproduce really dark parts of an image, which is essential when watching movies or playing games in low ambient light.
The left side of the image represents the display with stock settings, while the right one is with the “Gaming and Web Design” profile activated. On the horizontal axis, you will find the grayscale and on the vertical axis – the luminance of the display. On the two graphs below you can easily check for yourself how your display handles the darkest nuances but keep in mind that this also depends on the settings of your current display, the calibration, the viewing angle and the surrounding light conditions.
We test the reaction time of the pixels with the usual “black-to-white” and “white-to-black” method from 10% to 90% and vice versa.
We recorded Fall Time + Rise Time = 32 ms. The matrix is not one of the fastest.
PWM (Screen flickering)
Pulse-width modulation (PWM) is an easy way to control monitor brightness. When you lower the brightness, the light intensity of the backlight is not lowered, but instead turned off and on by the electronics with a frequency indistinguishable to the human eye. In these light impulses, the light/no-light time ratio varies, while brightness remains unchanged, which is harmful to your eyes. You can read more about that in our dedicated article on PWM.
The light emitted from this panel pulsates (uses PWM) up until 110 nits meaning that the display is comfortable for extended periods of use in this aspect.
Blue light emissions
Installing of our Health-Guard profile not only eliminates PWM but also reduces the harmful Blue Light emissions while keeping the colors of the screen perceptually accurate. If you’re not familiar with the Blue light, the TL;DR version is – emissions that negatively affect your eyes, skin and your whole body. You can find more information about that in our dedicated article on Blue Light.
You can see the levels of emitted blue light on the spectral power distribution (SPD) graph.
The display of Dell XPS 15 9575 2-in-1 is equipped with a touch-enabled panel by a manufacturer well-known for its innovations and elite displays. The bright and contrasty image, accurate colors and lack of PWM above 110 nits would have made it a great choice for many applications including presentations of web designers. However, we are using a conditional sentence because the sample has too high Luminance Nonuniformity along the surface of the screen compared to the center, which directly makes it not the most desirable device for color work.

Office Work should be used mostly by users who spend most of the time looking at pieces of text, tables or just surfing. This profile aims to deliver better distinctness and clarity by keeping a flat gamma curve (2.20), native color temperature and perceptually accurate colors.
Design and Gaming
This profile is aimed at designers who work with colors professionally, and for games and movies as well. Design and Gaming takes display panels to their limits, making them as accurate as possible in the sRGB IEC61966-2-1 standard for Web and HDTV, at white point D65.
THealth-Guard eliminates the harmful Pulse-Width Modulation (PWM) and reduces the negative Blue Light which affects our eyes and body. Since it’s custom tailored for every panel, it manages to keep the colors perceptually accurate. Health-Guard simulates paper so the pressure on the eyes is greatly reduced.

Now, we conduct the battery tests with Windows Better performance setting turned on, screen brightness adjusted to 120 nits and all other programs turned off except for the one we are testing the notebook with.
Despite its small dimensions, XPS 15 9575 2-in-1 features a 75Wh battery – impressive.
In order to simulate real-life conditions, we used our own script for automatic web browsing through over 70 websites.
For every test like this, we use the same video in HD.
We use F1 2017’s built-in benchmark on loop in order to simulate real-life gaming.
The Dell XPS 15 9575 2-in-1 comes with 2 different processors – Intel Core i5-8305G and Core i7-8705G. Both are based on the Kaby Lake architecture and differ only in clock speed and cache memory. The more powerful one, 8705G, outperforms significantly Core i7-8550U but drags with 8-9% behind the ULV Core i5-8300H.
|Intel Core i5-8305G||Intel Core i7-8705G|
|Cores / Threads||4/8||4/8|
|Base frequency / Turbo Boost||2.80 GHz / 3.80 GHz||3.10 GHz / 4.10 GHz|
|LL cache memory||6MB||8MB|
Both processors feature two graphics cards each – Intel HD Graphics 630 + AMD Radeon RX Vega M GL. There is a minimal difference in the maximum frequency of the HD Graphics chip – +100 MHz in favor of the i7-8705G (1.1 GHz vs 1.0 GHz).
Results are from the Cinebench 15 CPU test (the higher the score, the better)
Results are from the Fritz chess benchmark (the higher the score, the better)
Results are from our Photoshop benchmark test (the lower the score, the better)
As we already mentioned, no matter which processor you will opt for, you get HD Graphics 630 + AMD Radeon RX Vega M GL. It turned out that the latter is suitable even for gaming and it comes close in some tests to GeForce GTX 1050 Ti as regards performance. However, as far as games are concerned, the optimization is not on point at the moment. Either way, the XPS 15 9575 2-in-1 is far from being the most suitable for a gaming notebook.
Results are from the 3DMark: Fire Strike (Graphics) benchmark (higher the score, the better)
Results are from the Unigine Heaven 3.0 benchmark (higher the score, the better)
Results are from the Unigine Heaven 4.0 benchmark (higher the score, the better)
Results are from the Unigine Superposition benchmark (higher the score, the better)
Here we have to note that XPS 15 9575 2-in-1 works with V-Sync, which we weren’t able to turn off, so the minimum frames per second (if below 60) should be taken into account for potential comparisons. AMD Radeon RX Vega M GL is around 10-20% less powerful than GeForce GTX 1050 Ti in the gaming tests and approximately on par with GTX 1050.

Temperatures and Comfort
As it suits a serious business notebook, the temperatures of Dell XPS 15 9575 2-in-1 at high load are within the normal. At the hottest point, during extended processor work period at 100%, the degrees reached 50.7°C.
As we’ve already mentioned several times, the price of an XPS 15 9575 2-in-1 is pretty high. But if this is not a problem for you, then the machine is worth it in every aspect. Many business laptops, even high-end ones, are bulky and solid in order to be more reliable but XPS 15 9575 is only 9-16 mm thick, and in terms of dimensions looks like a 13-14-inch model thanks to its super slim bezels. However, this doesn’t mean it’s unreliable – its construction is made of aluminum, steel, carbon and Gorilla Glas 4 glass, and it also doesn’t sink in or make awkward noises even under significant pressure. The only setback as a result of the dimensions is the lack of USB Type-A ports, however, there is a dongle in the package.
Taking into account the size of XPS 15 9575 2-in-1, we were pretty surprised by the battery capacity – 75Wh turned out to be enough to supply the powerful processor and graphics card for more than one working day.
The screen has a very high color accuracy (with our Design and Gaming profile), and uses PWM only at low brightness levels (our Health-Guard profile fixes this issue).
