The Dell Inspiron 14 5425 is more affordable and offers good performance for general use with a decent battery life, making it suitable for everyday tasks and portable use. It's lighter, adding to its portability, but it lacks a high-performance GPU, which impacts tasks like 3D rendering, machine learning, and gaming. On the other hand, the Razer Blade 15 is pricier and features a more powerful CPU and GPU combination for intensive tasks such as 3D modeling, machine learning, gaming, and engineering. It has a higher capacity battery but shorter battery life due to its more powerful components, also weighing more which affects portability. Give Feedback

Sascha Mölck | August 2022
"A slim chassis, an acceptable weight (1.6 kg) and a real-world battery life of almost 13 hours turn the Inspiron into a mobile companion. Good: The battery can not only be charged using Dell's proprietary power adapter, but also with a universal USB-C power adapter (min. 45 watts). Office and Internet applications are handled by the built-in combination of Ryzen 5 5625U APU and 16 GB of RAM just as easily as modest computer games. Heat and noise development are generally okay, but the laptop should work a bit quieter under full load."

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."
