Henry T. Casey | April 2018
"The Dell Latitude 7490's got the speed you need (and then some), a keyboard that's comfortable enough for writing all day long and a battery that supports a full 8-hour workday. If only the display were brighter and it managed heat better. If you need every minute of battery life you can get, the extended-battery version of the Lenovo ThinkPad T480 lasts 8 hours longer than the Latitude 7490, but its display is much less colorful."

"The 2022 Blade 15 offers roughly 15 to 25 percent faster graphics performance and 20 percent faster CPU performance over last year's Core i7-11800H and RTX 3080 model. Thankfully, the system doesn't need to run noticeably louder or warmer to achieve faster results, but both power consumption and battery life take a hit. The higher consumption in particular appears to be a trend amongst many 12th gen Core laptops including the Schenker Uniwill Technology GM7AG8P or MSI Vector GP66 when compared to their previous generation counterparts. We're also glad to not see below-average CPU performance which was the case for the 10th gen Core i7-10875H model."
