Idle runtime at minimum brightness (still readable, 22 cd/m²) is over 23 hours. Here, the competition lasts just as long or longer. This runtime has little significance for practical use, which is why it is not available for all models. The unit I tried had a 2.1-megapixel 1080p webcam with a proximity sensor. I was a bit disappointed in the camera—even though it’s higher resolution than the 720p cameras I see on a lot of machines, the video was a bit softer in focus and had more of a tendency to whiteout than I’d like. It's adequate, but the cameras in the machines I've most recently tested from both Lenovo and HP are better than what I've seen from Dell. In my benchmarks, the 1145 tended to run 10 to 20 percent slower than the 1185-based systems, which wasn’t a surprise. On tougher tests, transcoding a 4K video to FHD took 3 hours and 15 minutes on the 7420 compared with two hours and 32 minutes on the 9420. A big Excel data table took 46 minutes to run, compared with about 41 on the other systems; and a MatLab portfolio simulation took 52 minutes, compared with 47-49 minutes on the others. One important thing to note: even this slower Tiger Lake chip performed notably better than the high-end 14nm Comet Lake chips that were in this class of machine a year ago. When I tested last year’s Latitude 7410 with a four core/eight thread Core i7-10610, the Excel data table took 63 minutes and the MatLab simulation took 73 minutes; so the difference is significant. Typical users should be quite pleased with the performance.
In 2023, Dell had an approximate 17% market share of global PC sales, ranking #3 after Lenovo and HP.New Intel Kaby Lake R processors have gone beyond what designers could previously imagine with a 15W budget, and the review model had an Intel Core i5-8350U quad-core 1.7GHz (Turbo 3.6GHz) processor under the hood, which is the equal of many desktop CPUs. Interestingly, the performance here is weirdly biased towards the integrated graphics, at the expense of pure computational power. Especially with the Core i7-1185G7, which is the top-of-the-line unit from the Tiger Lake lineup. As far as performance goes, the unit I had was based on an Intel Core i5-1145G7 processor (Tiger Lake), which has four cores and eight threads, with a rated speed of 2.6 GHz and a maximum turbo speed of 4.4 GHz, manufactured on Intel’s 10 nm SuperFin process. You can get it with the higher-end Core i7-1185, which has a base speed of 3.0 GHz and a turbo of 4.8 GHz, which is what the higher-spec laptops I’ve been testing this year have had. Both processors have integrated graphics and support vPro, Intel's enterprise management feature. The unit I used had 16GB of memory and a 512GB solid-state drive, similar to the others. Dell currently ships the Latitude 9420 with Windows 10 Pro, and the company plans to offer a Ubuntu Linux version starting later this year. Before I joined the tech-journalism ranks, I wrote on topics as diverse as Borneo's rain forests, Middle Eastern airlines, and Big Data's role in presidential elections. A graduate of Middlebury College, I also have a master's degree in journalism and French Studies from New York University.
The maximum temperature on the upper side is 37.1 °C / 99 F, compared to the average of 34.2 °C / 94 F, ranging from 21.2 to 62.5 °C for the class Office. Note: For a more detailed description about each location, please go to the system manuals at www.dell.com/manuals Table of Contents: There are hardly any tablets in this display size range anymore. For subnotebooks, on the other hand, it is the standard format. I'm also including the ThinkPad X1 Yoga, a 2-in-1 that competes with the convertible version of the Latitude 7420. Finally, since our Latitude is a clamshell laptop without a touch screen, a comparison with the 13-inch Apple MacBook Pro is also useful. Many corporate users covet Mac laptops, too.The unit I tested had a carbon fiber weave design, which I don’t find as modern as the aluminum case in the 9420, but it’s a good-looking laptop and carbon fiber is about 0.2 pounds lighter. Measuring 0.68 by 12.65 by 8.22 inches (HWD), the 7420 is a bit bigger than the 9420 two-in-one I tested (0.54 by 12.2 by 8.5 inches), but still pretty small (HWD). It’s actually lighter, with a starting weight of 2.7 pounds. The unit I tested, which has a touch screen, weighed 3.0 pounds, 3.8 pounds with the charger; the Lenovo Carbon X1 and HP EliteBook 840 Aero are both a little lighter, but this is an easy machine to carry. The bezels around the screen are noticeably larger, but that certainly doesn’t impact the usability of the machine. It has a solid, modern look. Ergonomically, this is one of the smaller machines in this category, if only by a few millimeters. There are smaller machines, like the Lenovo X1 Carbon, but this device is certainly very portable.

Flagship business laptops aren't meant for hardcore gaming, and the Latitude 7420 is no exception. It's nice to see Intel's newer Iris Xe integrated graphics outperform the older UHD Graphics of the ThinkPads, but the Dell's scores in our 3DMark and Superposition gaming simulations are nothing to get excited about.The ports haven’t changed at all from the 7480 series, with triple USB 3.1 (Gen 1) Type-A ports and a single Thunderbolt 3 USB Type-C. There is also an RJ-45 Ethernet port, Smart Card slot, microSD card and SIM card receptacles.
