If you need a laptop primarily for general use with the added benefit of good portability and a lower price, the Lenovo IdeaPad 5 15" would be a suitable choice; it offers a budget-friendly option with decent performance for everyday tasks, a comfortable keyboard, and a longer battery life. However, if you're looking for higher performance for activities like gaming, 3D rendering, or intensive engineering tasks, the Razer Blade 15 stands out with its powerful processor and high-end graphics card, though it comes at a higher cost and with a shorter battery life. The Razer Blade also has a higher resolution display with better color accuracy, making it well-suited for creative professionals. However, both laptops have similar portability with a minimal difference in weight. Give Feedback

Marcus Schwarten | August 2021
"The Lenovo IdeaPad 5 is convincing due to its long battery life. The device scores points especially with its large battery and long battery runtimes combined with its low consumption. The CPU and GPU perform in the test as one would expect, and in line with what was familiar from the somewhat smaller 14-inch sister model, the Lenovo IdeaPad 5 14."

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."
