Design and features

The two 15-inch laptops share a similar footprint, though the XPS 15 is actually the thinner laptop despite the powerful hardware options inside. It is, however, considerably heavier. The LG gram lives up to its name, weighing in at just 2.5 pounds (1.1kg). The non-touch XPS 15 with a smaller battery hits 4 pounds (1.8kg), while the touch models with a larger battery hit 4.5 pounds (2.0kg). If you want the most portable option to carry on frequent travels, the gram 15 should win you over.

Part of the gram's secret to weight loss is a magnesium alloy chassis, whereas the XPS 15 goes with machined aluminum and a carbon fiber palm rest. Both laptops have a premium look with attractive lines, and you're not going to feel out of place in a cafe or boardroom with either option. Ports are almost the same, with Thunderbolt 3 for a docking station, USB-A (the gram has one extra), HDMI, and 3.5mm audio. The XPS 15 includes a full-size SD card reader, while the gram 15 has a smaller microSD card reader.

Speedy Wi-Fi 6 connectivity comes standard in both laptops, setting you up for future networking. Both have an available fingerprint reader for increased security through Windows Hello, though neither offers IR facial recognition.

Laptops this size are built for productivity, so the keyboard and touchpad play a significant role. If you're a lover of number pads, only the gram 15 includes the extra keys. Both keyboards are backlit and shouldn't take long to get used to. We always recommend testing in person, but if you can't, just keep in mind that there's nothing wrong with either setup. As for the touchpad, both laptops use Precision drivers, and both are sized large enough that they won't interfere with productivity.

Display options are where the differences between these two laptops really begin to open up. The gram 15 has a single touch FHD IPS option available, albeit with high sRGB color reproduction and excellent contrast. If you'd like to up things to 4K, you'll have to turn to the XPS 15.

Dell's laptop has three different displays to choose from. Baseline models come with an FHD non-touch screen with perfect sRGB color reproduction and about 500 nits brightness. Moving up to 4K, choices are split between touch with 100% AdobeRGB color or OLED non-touch with 100% DCI-P3 color reproduction. OLED offers the best picture, but it's also the biggest drain on the battery. If you're looking at getting into specialized design and development work, one of these two 4K displays likely makes the most sense, especially when you factor in the performance hardware under the hood.

Thanks to 10th Gen Intel Core "Ice Lake" CPUs and integrated Intel Iris Plus graphics, the LG gram 15 will hold its own when given a considerable load. It's nothing miraculous, but it's going to perform well with standard office and productivity work. It also has two M.2 SSD slots, allowing you to add or upgrade storage after purchase.

The XPS 15 is what you'll want if performance truly matters. 9th Gen Intel Core H and HK CPU options shred, and the NVIDIA GTX 1650 dedicated GPU offers relatively impressive power for gaming and specialized work. Due to there being so many customization options, it's much easier to get precisely the laptop you need from Dell.

The LG gram 17 that we reviewed, which has the same 80Wh battery as the gram 15, is capable of hitting about 10 hours of life when going about standard productivity work. That should hold true here as well. On the other hand, the XPS 15 is a mixed bag. There are two battery sizes available, so those who want the best life possible should opt for the 97Wh option. A Core i5 CPU with an FHD display is likely going to push the same 10 hours as the gram 15. In our XPS 15 testing, a model with Core i9 CPU, GTX 1650 GPU, and 4K OLED display still managed about seven hours when not pushing the system.

Go with the XPS 15 for power and buying options

Thanks to beefy CPUs and dedicated NVIDIA GPU, the XPS 15 is the right choice for power-hungry users. Add in plenty of customization options, including two 4K displays, and you should find it easy to get exactly what you want.
