Dell used an Intel 545s M.2 SATA drive in the review hardware, and on paper, it looks fine. But in some of our writing tests, it didn’t perform that well, and the IOPS it delivers don’t compare favorably with those you’d get from a Corsair or Western Digital. Today’s Latitude 7490 retains the 1920x1080 resolution, but exchanges the embedded touch display of our previous unit with a conventional IPS, non-touch, matte panel. Subjectively, color seems vivid, contrast appears strong, and brightness is fairly good. Our measurements revealed an average brightness of 294 cd/m²—ever-so-slightly below that of the embedded touch model—and a very good contrast ratio of 1342:1. While the ThinkPad T480s and the EliteBook 840 G5 in our comparison table only achieve results slightly above these, the X1 Carbon absolutely blows them all away with an average brightness of 533 cd/m²—and the 840 G5 offers a superior FHD IPS display option with a mind-blowing 630 cd/m² result. While today’s screen is certainly nice enough, Dell should consider stepping up their options for the next model to stay in competition.

Temperatures haven’t changed much since the Core i7 model, with load averages on top/bottom 35.2 °C and 37.5 °C, respectively (within a degree C of the previous measurements—though room temperatures were also a degree higher during today’s measurements, so it’s really closer to 1.5 °C or so of a drop). Idle values are actually higher, which might be an idiosyncrasy of firmware or something similar (because no other logical explanation suffices). Here, we recorded values of 28.7 °C and 32.5 °C, well above room temperatures. The panel’s response times are a bit on the slow side, but PWM is not used for brightness management.
The CPU-related tasks all hit great numbers, and not far from what the Core i7-8550U-based machines are capable of. As they share an identical Intel UHD Graphics 620 GPU, the results for anything graphical are almost the same. There is so much to like in the Latitude 7490, despite it being a very derivative design from what came before. The new Intel silicon performs admirably, and this Dell machine has enough battery longevity so it won’t disappoint those who like to work on the move. The Latitude 7490 finished our HandBrake video transcoding test (converting a 4K video to 1080p) in 21 minutes and 35 seconds, which is only slightly shorter than the 22:11 category average. The MateBook X Pro (27:18) took longer, and the ThinkPad T480 (18:09) took less time.

The Dell Latitude 7490 gets warm, but only on the bottom . After we streamed 15 minutes of HD video on the notebook, our heat gun captured a temperature of 99 degrees Fahrenheit on the center of its underside, and up to 107 degrees closer to its hinge. Both temperatures exceed our 95-degree comfort threshold, while the readings from the touchpad (84 degrees) and keyboard (93 degrees) did not. This means that the measured response time is worse than the average of all tested devices (21.8 ms). I should note that I had to take the photo in front of the window, where I had natural light, because images taken at my desk were far darker. The average temperature for the upper side under maximal load is 35.2 °C / 95 F, compared to the average of 29.5 °C / 85 F for the devices in the class Office. The Dell Latitude 7490 offers decent battery life, but we've seen better. When running the Laptop Mag Battery Test (web browsing at 150 nits), Dell's laptop burned through its charge in 8 hours and 55 minutes, which is pretty close to the 8:50 average for premium notebooks. The Huawei MateBook X Pro (9:55) lasted an hour longer, while the Lenovo ThinkPad T480 lasted less time in the default configuration (8:07) but provided many more hours of activity with its extended battery (17:19).

The professionally-stylish heather gray exterior is also water resistant to protect your laptop from the weather. There isn’t room for a conventional 2.5-inch SATA device, though the M.2 slot will take a bigger module, and it is also compatible with NVMe PCIe M.2 drives.

The palmrests and touchpad are cooler than skin temperature with a maximum of 30.4 °C / 86.7 F and are therefore cool to the touch. What substantially helps this model is the 60WHr battery with a whopping 7500mAh, at least 20% more capacity than most competitive products offer. With this capacity, running all day including additional time on a commute is both realistic and practical.

By slim margins, it’s in fact the quietest machine in our field, topping out at just 40.2 dB(A) and averaging under load a mere 29.9 dB(A)—barely above the ambient noise measurement of 28.2 dB(A). Like all of its competitors, while idling, the fan rarely even engages; and even when it does, noise levels barely increase to a paltry 29.9 dB(A). The included Waves MaxxAudio Pro sound utility allows you to disable its sound-boosting presets, but I recommend you leave it as is. You'll see options for adjusting width, detail and bass, but the default settings are just right. While the 8 th-generation Intel CPUs all tend to experience an initial short burst of performance before subsiding somewhat, the Intel Core i7 in our previous 7490 review unit still distances itself from the Core i5-8350U in our CPU tests—ahead by some 9% and 15% in the Cinebench R15 multi- and single-core tests, respectively. After the first few runs, average multi-core scores are closer to the 530 mark in our tests—again, below the less-consistent but still quite a bit higher (roughly) 570 we received over the long-term from the Core i7 model.
