The XPS 13 (7390) is Dell’s retreaded convertible: The camera moves back up, the keyboard uses magnets and there is a 4K display. Thanks to Ice-Lake-U-Quadcore and up to 32 GB of RAM, the speed increases drastically, but the passive cooling is missing.

Features of Dell XPS 13 Laptop

Dell has unveiled the XPS 13 Convertible (7390), the successor to the XPS 13 Convertible (9365) of 2017. The 2-in-1 device is still a 360-degree convertible, but Dell has the XPS 13 except for the actual form factor has been completely reworked: the display, the camera, the processor, the memory, the cooling, the battery, the keyboard and one of the USB-C ports are new.

Dell XPS 13

With 297 x 207 x 13 mm at 1.32 kg, the XPS 13 (7390) is as compact as the previous XPS 13 Convertible with 304 x 199 x 13.7 mm at 1.24 kg. The micro-SD card reader and the 3.5 mm jack audio have remained, the eyelet for Noble Castle has disappeared; the side power button and the five-level LED battery indicator are also missing. 

Both USB-C sockets are now designed as Thunderbolt 3 and are connected to four PCIe Gen3 lanes for full speed for external graphics (eGPU).

For the 13.4-inch display, Dell advertises with a slightly slimmer frame around the panel. Instead of the 16: 9 format, they solve this in a 16:10 ratio, which should be pleasant in everyday work due to the additional vertical pixels.

The new XPS 13 is available with 1,920 x 1,200 or 3,840 x 2,400 pixels, both variants support touch and should provide a good brightness of 500 candelas per square meter. 

At least the lower-resolution panel has an anti-glare coating, according to Dell, while the 4K + should cover 90 percent of the DCI-P3 color space. The tiny 720p webcam sits above the center of the display instead of the previous one.

For the keyboard, Dell takes over the XPS 15 (9575) known Maglev technology: The keys are not returned by a diaphragm or a spring, but quickly magnetically return to their position – hence Maglev (Magnetic Levitation). 

At least with the XPS 15, the stroke is extremely short, which is why we do not get any tactile feedback, as pressing is hard right through. In the power button is a fingerprint sensor for biometric authentication via Windows Hello, all buttons are white backlit. The Precision trackpad with a glass layer is well known.

Inside the convertible, Intel just introduced Ice Lake U-chips are installed: In the previous XPS 13 still stuck Kaby Lake Y processors, so dual cores with 5 watts. The ICL-U, on the other hand, are 15W quad circuits, and Intel has redesigned the CPU and iGPU architecture. 

Dell speaks of the two and a half times performance in the Cinebench R15 nT, which should have the new XPS 13 compared to its predecessor. Instead of passive cooling, however, there are two fans, but due to the evaporation chamber including Gore insulation with light or short high load should not turn.

Matching to the processors, Dell soldered up to 32 GB instead of 16 GB of memory and very fast LPDDR4-3733 instead of LPDDR3-1866. In addition, NVMe PCIe Gen3 x4 SSDs with up to 1 TB instead of previously up to 512 GB, but these are now also soldered instead of being plugged in M.2 format.

The battery capacity increases from 46 watt-hours to 51 watt-hours, resulting in a runtime of up to 16 hours instead of up to 15 hours. When testing the previous XPS 13 Convertible (9365), however, we achieved only 10 hours under light load and average brightness of 150 cd / m². 

The new XPS 13 supports Bluetooth 5 and 802.11ax WiFi (WiFi 6) via the AX1650 module.
