The Dell Inspiron 14 7425 might offer everyday efficiency with respectable battery life at a more affordable price, which is adequate if you prioritize work and leisure usage without heavy graphics demands. On the other hand, the Razer Blade 15 is designed for high-performance gaming, 3D rendering, or machine learning tasks, providing top-tier graphics and processing power but at a higher cost and potentially shorter battery life. The Razer Blade 15 is less portable due to its weight and size, targeting users who need a mobile workstation rather than a device for casual use. Consider your primary activities and whether high-end graphics and processing capabilities justify the extra expense and reduced portability. Give Feedback

Jared Newman | December 2021
"Overall, this Dell Inspiron 14 2-in-1 offers a lot to like, especially at its oft-discounted price of $800. It’s a sturdy laptop with strong performance, a convertible touchscreen, loud speakers, and a convenient fingerprint reader. But the trade-offs you’ll make in pursuit of that lower price—most notably the dim display and stiff trackpad—might just keep you from outright loving it."

Allen Ngo | March 2022
"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."
