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. on Dell internal analysis using publicly available specs in August 2023 comparing maximum effective capacity for PowerStore 1200 and FlashArray //X20. Assumes average 4:1 data reduction for PowerStore, 5:1 for Pure Storage. Actual results vary. We strongly recommend springing for the upgraded 4-cell, 63-watt-hour battery in our review unit, since the base model comes with a 3-cell, 42-watt-hour battery that likely won't last as long. 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. We also run a custom Adobe Photoshop image-editing benchmark. Using an early 2018 release of the Creative Cloud version of Photoshop, we apply a series of 10 complex filters and effects to a standard JPEG test image, timing each operation and adding up the total. As with Handbrake, lower times are better here. The Photoshop test stresses the CPU, storage subsystem, and RAM, but it can also take advantage of most GPUs to speed up the process of applying filters, so systems with powerful graphics chips or cards may see a boost.
Dell Latitude 14 3420 features a Full HD IPS screen, model number Sharp XWXRY-LQ140M1 (SHP1542). Its diagonal is 14″ (35.6 cm), and the resolution – 1920 х 1080. Additionally, the screen ratio is 16:9, the pixel density – 157 ppi, their pitch – 0.16 x 0.16 mm. The screen can be considered Retina when viewed from at least 55 cm (from this distance, the average human eye can’t see the individual pixels). Obviously, this device is entirely made out of plastic. It weighs 1.52 kg and has a profile of 17.6mm, which makes it pretty compact. On the other hand, the plastic material is not very structurally sound, as the base shows quite a lot of flex when twisted. 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. Hard drive retention: Hard drive retention is not available on models with a soldered hard drive, including XPS 9315 2in1, Chromebooks or Venue tablets, except the Venue 11 Pro. In this test we use 100% on the CPU cores, monitoring their frequencies and chip temperature. The first column shows a computer’s reaction to a short load (2-10 seconds), the second column simulates a serious task (between 15 and 30 seconds), and the third column is a good indicator of how good the laptop is for long loads such as video rendering.

Storage performance as measured by PCMark 8 proved roughly equal across the Latitude 7420 and its competitors, since they all use speedy SSDs as their boot drives. Estimated valueis Dell’s estimate of product value based on industry data, including the prices at which third-party retailers have offered or valued the same or comparable products, in its most recent survey of major online and/or off-line retailers. Third-party retailer data may not be based on actual sales. To be honest, the laptop is worth its money if it’s going to be used as an everyday office device. Indeed, it is a bit boring, and the build quality is not great, but the features outweigh the quirks in our opinion. Accidental Damage-Additional Information: Accidental Damage Service excludes theft, loss, and damage due to fire, flood or other acts of nature, or intentional damage. Customer may be required to return damaged unit to Dell. Limit of 1 qualified incident per contract year. For more information, consumers visit Accidental Damage Service Contract (Consumer) or commercial customers visit Accidental Damage Service Contract (Commercial). Weirdly, the Latitude 14 3420 performs better than its larger 15-inch brother. Indeed, the temperature of the CPU is a bit high. But it’s worth mentioning that we used the “Ultra Performance” profile from the BIOS settings. This allows you to get the maximum out of the processor. Well, as much as the cooling solution can provide anyways. Comfort during full load

Sound quality is basic for such an expensive laptop. With a mic integrated into the webcam assembly and dual stereo speakers, videoconferencing and voice calls are clear but not exceptional on the Latitude 7420. The ThinkPad X1 Carbon also offers a basic audio experience; even Dell's flagship Latitude 9410 uses a similar audio setup. CompleteCover: Service is available for personal computers, Axim PDAs, Dell branded projectors and LCD TV. CompleteCover excludes theft, loss, and damage due to fire, intentional damage, acts of God or natural disasters, animals, pets or pests. Customer may be required to return unit to Dell. This service is only available in selected countries. The results of our Handbrake video editing trial are clustered close together, and although the Latitude 7420 tied for last place the differences were negligible. Handbrake is another tough, threaded workout that's highly CPU-dependent and scales well with cores and threads. In it, we put a stopwatch on test systems as they transcode a standard 12-minute clip of 4K video to a 1080p MP4 file. It’s a timed test, and lower results are better. Before we go to the test results, let’s take the laptop out of the box, and see the inevitable cost-cutting measures on the outside.
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. In addition to that, you get a choice of three displays. The first is a 768p TN panel, which should be avoided at all costs. Then, there is a 1080p IPS one, which has a narrow color coverage but is the sweet spot for business computing. And the last one supposedly covers 100% of the sRGB gamut and should be suitable for color-sensitive work. Dell’s Latitude 3000 series is definitely not among the premium offerings from the marque. This is clearly visible by observing the outside of the Latitude 14 3420. It is entirely made out of plastic, and unfortunately – the body doesn’t have a very rigid structure.
The maximum measured brightness is 273 nits (cd/m2) in the middle of the screen and 255 nits (cd/m2) average across the surface with a maximum deviation of 12%. The Correlated Color Temperature on a white screen and at maximum brightness is 6410K (average) – slightly warmer than the 6500K optimum for sRGB. ProSupport Plus includes Keep Your Hard Drive & Accidental Damage Protection to cover everyday accidents like drops, spills or electrical surges. Standard wireless connectivity comprises an Intel Wi-Fi 6 (802.11ax) chipset with built-in 2x2 MIMO support and Bluetooth 5.1. The Latitude 7420 supports eSIM, so if you opt for the optional mobile broadband and your carrier supports eSIM as well, you won't need to use the physical slot. First responders and public safety organizations eyeing the Latitude 7420 may appreciate that the LTE version supports the dedicated, high-capacity FirstNet LTE bands. All other products will be delivered via the fastest available method (excluding bank holidays and weekends) and generally within 3-5 days, depending on customer location.
The next figure shows how well the display is able to reproduce really dark parts of an image, which is essential when watching movies or playing games in low ambient light. The Latitude 7420 finished in about the same amount of time as the Elite Dragonfly Max, significantly ahead of the 10th Gen Core i5 Carbon. Graphics and Battery Testing: Running Time to Spare
