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.
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. 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.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’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.
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. 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. 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. 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 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.
