"Latitude’s first ever 16” model" - this is how the manufacturer labels the Dell Latitude 16 7640. It looks like the main focus here is the screen that comes with a 16:10 aspect ratio. The panel is taller so you'll have more space for work or entertainment. It's a business device but it has two huge front-firing speakers and that's why you'll not see a NumPad here. The device relies on a 13th Gen Intel Raptor Lake U and P chips. You can choose among seven CPU options so you can bring the price down if you don't need extra processor power and pick an i5 U-series chip (actually, even the base processor variant is potent enough for daily and office tasks). Or you can get a 28W P-series variant if you want to prioritize performance over battery life. At least for now, there are two 1200p IPS display models. That's okay but the absence of higher-resolution panels is a bit strange in this price class. On the bright side, the laptop brings functions that will ease your life at home or in the office such as Wi-Fi 6E, an optional WWAN slot, a battery-saving Mini-LED backlit keyboard, a Web camera with a privacy shutter, and a lot of security features. You can check the prices and configurations in our Specs System: https://www.dell.com/support/home/en-us/product-support/product/latitude-16-7640-laptop/drivers Specs, Drivers, What's in the box Drivers All drivers and utilities for this notebook can be found here: https://www.dell.com/support/home/en-us/product-support/product/g-series-16-7630-laptop/drivers What's in the box? Inside the box, you will find some manuals, the laptop itself, and a 65W Type-C adapter. There are two more variants - a 60W model for the least powerful machines and a 100W charger for the top-end configurations. Design and construction The device looks sleek and modern with its minimal branding and rounded corners. The laptop is made of aluminum and it feels premium to the touch. However, the lid rigidness is average - you can flex it but not too much. The base sturdiness is okay if we don't count the zone between the hinges and the area around the touchpad. You can open the lid with a single hand. The dimensions of the laptop look good for a 16-incher - 1.835 kg and 19.5 mm thickness. The bezels surrounding the panel are thin and this contributes to the overall modern look. The Web camera has a privacy shutter. There are two options here with Temporal Noise Reduction - both with 1080p resolution but the higher tier version has IR functionality and an Ambient Light sensor. The lid acts as a lever and it'll lift the back of the laptop when the angle of opening gets past the 90-degree mark. This enhances the cooling capabilities of the laptop and it also leads to better ergonomics during typing. Now, the optional Mini-LED backlit keyboard should be much more battery-friendly compared to a normal backlight, at least on paper. The board is comfortable for usage, the keycaps are big, and there is plenty of free space around them. The feedback is clicky and the key travel is long. The optional fingerprint reader is built into the Power button. Audiophiles should like the two huge speakers around the keyboard but because of that, the NumPad zone isn't on board. The touchpad is big and accurate. However, the clicking mechanism needs some fine-tuning because pressing the pad feels kind of sluggish and clicks are loud. Let's flip the notebook upside down. This reveals the two long rubber feet, a large ventilation grille, and two speaker cutouts. The hot air is pushed through a long vent on the back. Part of the heat is reaching the display during heavy CPU stress. Ports On the left, there is an HDMI 2.0 connector followed by two Thunderbolt 4 ports (with power delivery and DisplayPort capabilities) and an optional Smart card reader. On the right, you get a lock slot, two USB Type-A 3.2 (Gen. 1) ports (the former supports the PowerShare function), an Audio jack, and a NanoSIM slot (option). Display quality, Health impact (PWM), Sound Dell Latitude 16 7640 is equipped with a WUXGA (Wide Ultra XGA) IPS panel, model number Innolux BOE JFDKM-NV16WUM (BOE0A34). It comes with a 60Hz refresh rate. Its diagonal is 16" (40.6 cm), and the resolution - 1920 x 1200p. Additionally, the screen ratio is 16:10, the pixel density – 141 ppi, and their pitch – 0.18 x 0.18 mm. The screen can be considered Retina when viewed from at least 61 cm (from this distance, the average human eye can’t see the individual pixels). Viewing angles are good. We offer images at different angles to evaluate the quality. Also, a video with locked focus and exposure. The maximum measured brightness is 283 nits (cd/m2) in the middle of the screen and 274 nits (cd/m2) average across the surface with a maximum deviation of 8%. The Correlated Color Temperature on a white screen and at maximum brightness is 6490К. In the illustration below you can see how the display performs from a uniformity perspective. The illustration below shows how matters are for operational brightness levels (approximately 140 nits) – in this particular case at 52% Brightness (White level = 141 cd/m2, Black level = 0.11 cd/m2). Values of dE2000 over 4.0 should not occur, and this parameter is one of the first you should check if you intend to use the laptop for color-sensitive work (a maximum tolerance of 2.0). We measured a good contrast ratio - 1240:1. To make sure we are on the same page, we would like to give you a little introduction to the sRGB color gamut and the Adobe RGB. To start, there’s the CIE 1976 Uniform Chromaticity Diagram that represents the visible specter of colors by the human eye, giving you a better perception of the color gamut coverage and the color accuracy. Inside the black triangle, you will see the standard color gamut (sRGB) that is being used by millions of people on HDTV and on the web. As for the Adobe RGB, this is used in professional cameras, monitors, etc for printing. Basically, colors inside the black triangle are used by everyone and this is the essential part of the color quality and color accuracy of a mainstream notebook. 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. The yellow dotted line shows Dell Latitude 16 7640's color gamut coverage. Its display covers 50% of the sRGB/ITU-R BT.709 (web/HDTV standard) in CIE1976, and 39% of DCI-P3, ensuring a super vibrant and attractive picture. We tested the accuracy of the display with 24 commonly used colors like light and dark human skin, blue sky, green grass, orange, etc. Below you can compare the scores of the Dell Latitude 16 7640 with the default settings 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. The left side of the image represents the display with stock settings, while the right one is with the “Gaming and Web Design” profile activated. On the horizontal axis, you will find the grayscale, and on the vertical axis – the luminance of the display. On the two graphs below you can easily check for yourself how your display handles the darkest nuances but keep in mind that this also depends on the settings of your current display, the calibration, the viewing angle, and the surrounding light conditions. Response time (Gaming capabilities) We test the reaction time of the pixels with the usual “black-to-white” and “white-to-black” method from 10% to 90% and vice versa. We recorded Fall Time + Rise Time = 16 ms. After that, we test the reaction time of the pixels with the usual “Gray-to-Gray” method from 50% White to 80% White and vice versa between 10% and 90% of the amplitude. Health Impact: PWM (Screen flickering) Pulse-width modulation (PWM) is an easy way to control monitor brightness. When you lower the brightness, the light intensity of the display is not lowered, but instead turned off and on by the electronics with a frequency indistinguishable to the human eye. In these light impulses, the light/no-light time ratio varies, while brightness remains unchanged, which is harmful to your eyes. You can read more about that in our dedicated article on PWM. Dell Latitude 16 7640's display doesn't use PWM for brightness adjustment. Health Impact: Blue light emissions 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. Health Impact: Gloss-level measurement Glossy-coated displays are sometimes inconvenient in high ambient light conditions. We show the level of reflection on the screen for the respective laptop when the display is turned off and the measurement angle is 60° (in this case, the result is 48.6 GU). Sound Dell Latitude 16 7640's speakers produce a sound of pretty good quality. Its low, mid, and high tones are clear of deviations.

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. Average P-core frequency; Average E-core frequency; CPU temp.; Package Power Intel Core i7-1365U (15W TDP) 0:02 - 0:10 sec 0:15 - 0:30 sec 10:00 - 15:00 min Dell Latitude 16 7640 3.53 GHz @ 2.66 GHz @ 73°C @ 44W 3.50 GHz @ 2.63 GHz @ 86°C @ 44W 2.79 GHz @ 2.04 GHz @ 72°C @ 28W The Core i7-1365U can maintain stable ~3.50 GHz for the P cores and ~2.60 GHz for the E cores in short and medium loads which is a very good result. In the long run, the performance cores can boost close to the 2.80 GHz mark and we can see a 2.04 GHz frequency for the efficient cores. That's why the Dell Latitude 16 7640 feels very responsive no matter the task. Gaming comfort Even in "Ultra Performance" mode, the two fans are literally quiet (but not silent) during heavy CPU load. In this scenario, the left and the central part of the keyboard (as well as the two palm rest zones) feel warm but that's okay for normal usage. Battery Now, we conduct the battery tests with the Windows Better performance setting turned on, screen brightness adjusted to 120 nits and all other programs turned off except for the one we are testing the notebook with. The 57Wh battery lasts for 12 hours and 30 minutes of Web browsing, or 11 hours and 6 minutes of video playback. That's a great result for such a capacity! Disassembly, Upgrade options, and Maintenance To access the laptop's internals, you have to undo 8 Phillips-head screws. The easiest way to pop the bottom plate with a plastic tool is to start from one of the top two corners. Here's how the bottom plate looks on the inside. Our laptop is configured with the optional 57Wh battery pack, the base version is a 38Wh variant. For removing the unit, pull out the connector from the mainboard, and undo the 4 Phillips-head screws that secure the unit to the base. The optional model has enough juice for 12 hours and 30 minutes of Web browsing, or 11 hours and 6 minutes of video playback. A great result given the modest capacity! Here we have soldered memory that always comes in a dual-channel configuration. Still, the maximum amount of RAM is 32GB of LPDDR5-4800MHz which should be enough for most people. For storage, there is just one M.2 slot compatible with 2230 Gen 4 NVMes. The preinstalled SSD is protected by a metal shroud that has a thin cooling pad on the inside. There is a WWAN slot for optional 5G connectivity which is also covered by a metal cap with a preapplied thermal pad. The cooling looks good for a machine that lacks a dedicated GPU. It comprises two fans, a couple of heat pipes, a large heat sink, and a heat spreader. Storage performance The SSD of our laptop is 512GB KIOXIA KBG50ZNS512G. Below you can see some benchmarks of this SSD. It reaches just 41°C during stress. Verdict The Dell Latitude 16 7640 surprises us with its snappy performance. The cooling is potent enough with its two fans, a pair of heat sinks, and a hefty heat sink. This results in a high CPU P and E core clock no matter the load as well as a 72°C processor temperature during longer stress. On top of that, the fans are quiet, and the base feels warm, but not hot to the touch. Yes, this is a fast laptop that is also comfortable for usage when you want to push the hardware to its limits. Perhaps the implemented lever mechanism of the lid also helps because it lifts the back of the laptop which provides more fresh air to the cooling system. By the way, the iGPU performance is more than enough for light games. You can play CS:GO with ~87FPS on Max details or Dota 2 on Normal quality with 94FPS - not bad for an integrated solution. The memory works in dual-channel mode so this positively affects the power of the Intel Iris Xe Graphics G7 (96EU). This leads us to the fact that RAM is soldered but the maximum possible amount of 32GB LPDDR5-4800MHz seems plenty. On the flip side, there is just one M.2 Gen 4 slot for the shorter 2230 SSDs. The 16-inch IPS display (BOE JFDKM-NV16WUM (BOE0A34) gets the job done for home and office usage. It's taller thanks to the 16:10 aspect ratio, the viewing angles are wide, and the contrast ratio is good. The panel also lacks PWM usage so long hours of work shouldn't be a problem if you take regular breaks from time to time. The sRGB color coverage is low - it's not a mandatory thing for an office notebook but for sure we would like to see a better panel in this price range. The keyboard is definitely comfortable for typing and it has an optional Mini-LED backlight that should be more energy-efficient. Maybe that's true because the battery life is surprisingly long for a 57Wh capacity - 12 hours and 30 minutes of Web browsing, or 11 hours and 6 minutes of video playback. The big touchpad is smooth and accurate, but it's loud when pressed and the clicks feel a bit slower than usual. The I/O is up to date - four USB ports, two of which are Thunderbolt 4 connectors. The Smart card reader and the NanoSIM slot are optional. At the end of the day, there isn't a lot to moan about the cons of this machine. It's pricey and the lid is a bit flexy - perhaps these are two major downsides. On the bright side, the aluminum build feels premium, the performance is great, the Web camera has a privacy shutter, the audio quality is very good, and the portability is on point.
