Most of the changes are on the inside for this generational refresh, with the 9315 model getting new processors, RAM and storage. It’s still one of the best Dell laptops available, and it’s a standout for the best Windows laptops, too. Here’s a breakdown of the specs you’ll find in both XPS 13 laptops.

Design and features

The new XPS 13 (9315) looks a lot like the 9310 model. It lacks the new haptic touchpad, capacitive feature row, and fancy keyboard of the XPS 13 Plus (9320), which helps keep the price down. The 9315 is slightly thinner and lighter than the 9310, and it’s available in two new colors: Sky and Umber.

In his OLED XPS 13 (9310) review, editor Daniel Rubino said the laptop “is the pinnacle of non-convertible 13-inch Ultrabooks.” Many design choices and features are retained for the 9315.

The keyboard is still outstanding, and Dell makes great use of the space below for a sizable touchpad. Both laptops have a maximum output of 4W from stereo speakers, and both have 720p webcams with IR for Windows Hello. The 9315 goes one step further by separating the RGB and IR parts for a clearer picture, and it now features Dell ExpressSign-In. This is a fancy name for human presence detection, which can lock and unlock your PC automatically when you arrive or leave. An ambient light sensor is built into both laptops.

We saw the XPS 13 ports get lighter on the Plus model (9320), and that trend continued with the 9315. There are now just two Thunderbolt 4 ports. If you’re not looking to connect to a Thunderbolt 4 hub or dock, the XPS 13 (9310)’s extra microSD card reader and 3.5mm audio jack might steer you back to the old PC.

The 9315’s wireless module has upgraded to Wi-Fi 6E, while the 9310 still uses Wi-Fi 6. If you want to use the 6 GHz spectrum, you’ll have to stick with the 9315. Fingerprint integrated into the power button for additional biometric security.

The 9315 and 9310 models of the XPS 13 both have 13.4-inch screens with a 16:10 aspect ratio, Dolby Vision, and Eyesafe certification. You can get 1920×1200 resolution (FHD+) in touch or non-touch, with an anti-glare finish for the former and an anti-glare finish for the latter. There’s also a UHD+ option for both PCs, with touchscreen, 500 nits brightness, HDR 400, anti-glare finish and 90% DCI-P3 color coverage.

Dell added a 3.5K OLED display option to the 9310, but unfortunately it doesn’t appear to have carried over to the 9315. It’s now offered in the XPS 13 Plus (9320) to help boost the appeal premium. XPS 13 (9310) models are dwindling as stock goes, but you can still find the 3.5K OLED display at select retailers.

Performance and price

This is where the XPS 13 (9315) really shines. It features the new 12th Gen Intel Core U-series processors along with faster LPDDR5-5200 RAM and speedy PCIe 4.0 SSD storage. Up to 32 GB of RAM can be obtained from the factory, as well as a drive of up to 1 TB. If you want the best possible performance, the 9315 model is definitely the laptop for you.

That’s not to say the XPS 13 (9310) isn’t also a workhorse. Its 11th Gen Intel Core processors are still very fast and you can get up to 32GB of LPDDR4x-4267 RAM and up to 2TB of M.2 PCIe 3.0 storage.

The 9315’s battery is actually a hair smaller at 51Wh (up from 52Wh), but you should expect about the same battery life depending on which display you choose. The XPS 13 (9310) with FHD+ display lasted over 10 hours in our tests, and you should expect the same from the 9315.
