When we measured the E5470's display with our colorimeter, it reproduced 113.1 percent of the sRGB color gamut. That's well above the average thin-and-light notebook (83.2 percent), and it also beats the EliteBook, ThinkPad and Tecra.
Additionally, when I was multitasking with Chrome and Windows Defender, the space to the left of the keyboard spiked a temperature of 115 degrees. That unpleasant mark didn't change when we set the AMD Catalyst Control Center to "Optimize power savings" or "Force power-saving graphics." Changing the Dell Power Manager utility's Thermal Management setting from Optimized to Cool did not help, either. The E5470 may disappoint road warriors, as it offers shorter endurance than other business laptops. The system lasted 7 hours and 16 minutes on the Laptop Mag Battery Test (Web surfing with 100 nits of brightness). While that runtime beats the EliteBook (5:54), it's shorter than the ThinkPad (7:31, 15:26 with extended battery), Tecra (8:23) and the average thin-and-light notebook (8:14).
When it comes to formal benchmarks, the battery life falls a bit short of its nearest competitors. On the Peacekeeper battery test the Latitude managed just over four and a half hours, while the Thinkpad, which features hot-swappable batteries, managed about four hours and fifty minutes, with the XPS 13 lasting about six minutes longer. The E5470 also performed well in the Delta-E test for color accuracy (where best scores are closer to 0), with a mark of 1.07. The Tecra (0.9) was slightly better in this test, but the Latitude's colors are more precise than those of the EliteBook, ThinkPad and average ultraportable notebook. Despite having a mostly plastic body, the Latitude E5470 is built like a small, plastic tank. The body doesn’t flex, or give in any troubling way, and it would absolutely survive several years of being hauled in and out of a messenger bag, facing the rigors of daily use.
The Dell Latitude E5470's strong performance seems to come at the price of a few hot points on the notebook. After 15 minutes of streaming video on the laptop, the notebook's undercarriage hit an uncomfortable temperature of 104 degrees Fahrenheit, well above our 95-degree threshold. The notebook's touchpad and keyboard were a cooler 82 and 92 degrees, respectively. The Latitude E5470 scored a solid 9,760 on Geekbench 3, a synthetic benchmark that measures overall performance. That mark handily beats the results earned by the AMD A12-powered EliteBook 745 G3 (5,494), Core i5-5300U-powered ThinkPad T450s (5,993), Core i7-5600U-powered Tecra Z40t-B (6,427) and the average thin-and-light notebook (6,229).The E5470 comes with Dell's standard Limited Hardware Warranty, which has one year of mail-in services that require after remote diagnosis. The Latitude E5470 isn’t going to win any industrial design awards, but it has a certain quiet elegance.
