[In-Depth Comparison] Dell XPS 13 9310 vs Dell XPS 13 9305 – very similar yet too different

The XPS series from Dell offers some of the most recognizable business laptops and ultrabooks, from the very-portable 13-inch devices that we will cover today, to the larger 17-inch laptops that don’t shy away from more powerful hardware.

Today we have the two XPS 13 laptops, the 9310 and 9305, which come with efficient Tiger lake U-series processors, integrated Iris Xe Graphics, and displays with very high resolutions, especially for the screen size.

Today we are giving you an in-depth comparison between the Dell XPS 13 9310 and the XPS 13 9305.

Design and construction

Both laptops come with an identical chassis, which is built using metal, carbon fiber, and glass fiber. This allows for the body to be both thin and light, making for some of the most portable devices. In terms of looks, both sport rounded corners, sharp edges, and a debossed Dell logo. In terms of weight and height, both laptops hover around the 1.20 kg to 1.30 kg mark.

Keyboard and touchpad

The bases do have some differences, with the keyboard of the XPS 13 9310 spanning wider, leading to less space on the sides. This leads to the power button getting mashed into the other buttons, which isn’t optimal as it can lead to accidental presses and shutdowns. As for the overall typing and user experience, both laptops come with surprisingly long key travel, considering the thin profile, however, it’s still nowhere close to gaming and workstation devices. The feedback is also a lot more clicky on the 9310.

As for the touchpads, both of them come with the same finish, amazing gliding and accuracy, and unrivaled responsiveness. It’s the closest experience to the MacBook pads that we have seen.

The XPS 13 9310 might as well take the title as the laptop with the most scarce I/O, offering only two Thunderbolt 4 connectors, a MicroSD card slot, and a 3.5 mm audio jack. Inside the package, you also get a Thunderbolt 4 to USB Type-A adapter. The XPS 13 9305 forgets the adapter but adds one more USB Type-C 3.2 (Gen. 2) port.

Display quality

The XPS 13 9310 comes with three 13.4-inch 16:10 panels. The base configuration has an FHD+ IPS panel. If that’s not enough, you can pick between a UHD+ IPS panel and a 3.5K OLED panel.

The XPS 13 9305 has 16:9 panels, with one Full HD panel and one 4K UHD panel. We tested the FHD panels on both notebooks, which come with a similar pixel density of 169 PPI and 166 PPI, a pitch of 0.15 mm x 0.15 mm and 0.153 mm x 0.153 mm, and a Retina distance of 50 cm and 53 cm, respectively for the XPS 13 9310 and XPS 13 9305.

Color coverage

To make sure we are on the same page, we would like to give you a little introduction to 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 on 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 yellow dotted line shows the color coverage of both the XPS 13 9310 and the XPS 13 9305.

Both laptops show near full sRGB coverage, with 96% for the 9310 and 99% for the 9305.

Color accuracy

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 in factory condition and also, with the “Design and Gaming” profile.

Below you can check the results from the test of both laptops, with both the factory settings (left) and with our “Design and Gaming” profile applied (right).

Both devices make huge gains with our profile, lowering the dE value to around 1.

Response time (Gaming capabilities)

We test the reaction time of the pixels with the usual “black-to-white” and “white-to-black” methods from 10% to 90% and vice versa.

Both laptops have very close results with a difference of only 0.7 ms. Still, the XPS 13 9305 has a Fall + Rise time of 38.2 ms.

Health Impact / PWM (Blue light)

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 from 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.

Both laptops show PWM usage, up to 140 nits for the XPS 13 9310 and up to 115 nits for the XPS 13 9305.

Blue light emissions

Installing 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 won’t find any large differences between the two devices, as they are essentially the same, using the same hardware and a lot of other components. Although both are built from a combination of aluminum and carbon fiber, the devices sport different designs. Due to the 16:10 aspect ratio, the XPS 13 9310 has a higher screen-to-body ratio and generally looks better. It also presents a better keyboard, which offers much clickier feedback.

We will put the I/O as a draw, as despite the one more USB Type-C port, the 9305 forgets the Type-A adapter, which is a versatile addition to the 9310. Both laptops have quality displays with high color coverage and amazing accuracy. They also both utilize PWM at lower levels of brightness.

We would favor the 9305 in the battery tests, as it shows a more noticeable difference in video playback. Completely expected, the same device also shows higher performance thanks to its Core i7-1165G7 and Iris Xe Graphics G7 combo, which can be seen both in benchmarks and in games. The laptop has higher clock speeds across all three stages of our stress test. It’s also cooler on the outside, which doesn’t affect performance, but will equate to a more comfortable experience.

We’re really struggling to pick a winner, as you’re not losing a lot by picking either of these. With their efficient CPUs and quality displays, you can definitely do Creator work on the go.

Why choose the Dell XPS 13 9310?

  • + Speakers with no deviations across all frequencies
  • + 16:10 displays
  • + Keyboard with clickier feedback

Why choose the Dell XPS 13 9305?

I have owned the XPS 13 9305 for just over 6 months now – and – love it. I have a fairly lower-end configuration of 8 GB RAM and 125 GB SSD, however, it does everything I need it to – and – has demonstrated an amazing battery life! The 16:9 display is crisp and ample. The keypad is responsive – and – the camera does the trick. I highly recommend this product for anyone demanding an “as good as get’s” laptop!
