About this deal

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. 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. Buyers can choose between a 42 Wh or 63 Wh battery. Our model was equipped with the ExpressCharge battery with four cells and 63 Wh. Fast charging is detrimental to battery life, which is why it has to be selectively activated in the Dell Power Manager. After that, the battery charges to 80% in one hour. The Latitude lasted 14 hours at 100% in the Wi-Fi test with reduced brightness to 150 cd/m², which is a very good value. Only the Ryzen ThinkPad T14s can top this figure.

Dell Latitude 7420 Review: Windows PC - Maximum Security Dell Latitude 7420 Review: Windows PC - Maximum Security

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. 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. 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.

Dimensions & Weight

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. 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. 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. Up to 2400 Mbps in dual-band 2.4GHz/5GHz WiFi 802.11 a/b/g WiFi 4 (802.11n) WiFi 5 (802.11ac) WiFi 6 (802.11ax) Bluetooth 5.1 The multi-core rate falls short of our expectations, especially when you look at the smaller i5-1135G7 ( ThinkPad X1 Carbon). The Core i7 Tiger Lake in the test field performed more or less better, depending on the cooling system. The ThinkPad T14s with the Ryzen 5850U are right in front. In the single-core tests, we see the i5-1145G7 11% behind the Ryzen 7 Pro 5850U and 8% behind the ThinkPad T14's Core i7-1165G7.

The CPU and graphics are optimized for light office work. Dell's power control allows for whisper-quiet work with little waste heat or, alternatively, moderate performance. However, this 14-incher is not made for continuous performance. Anyone looking for this should look at AMD Ryzen alternatives ( ThinkPad T14s) or individual Core i7 models ( ThinkPad T14 Gen2). Installing our Health-Guard profile not only eliminates PWM but also reduces the harmful Blue Light emissions while keeping the colors of the screen perceptually accurate. If you’re not familiar with the Blue light, the TL;DR version is – emissions that negatively affect your eyes, skin, and your whole body. You can find more information about that in our dedicated article on Blue Light. Conclusions

Testing the Latitude 7420: Getting Work Done Is a Cinch

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 Dell's hardware offering includes a wide range of 7420 clamshell and 2-in-1 SKUs from 1,275 to 2,950 Euros with 11th-generation Intel Tiger Lake U CPUs and the options of vPro, 8GB or 16GB permanently soldered RAM, and M.2 PCIe SSDs. The touchscreen and 4K option of the predecessor are omitted, while the FHD touchscreen is only available in the 2-in-1 system.
