If you value high performance for tasks like gaming, 3D modeling, or video editing, investing in the Razer Blade 15 makes sense despite its higher price; however, its bulkier design and possibly shorter battery life compared to the Lenovo ThinkBook 13x could make it less ideal for on-the-go usage. The Lenovo ThinkBook 13x offers more portability and longer battery life, making it suitable for general use, but it may not handle intensive tasks as well as the Razer. Consider your primary use and whether the additional cost is justified for your needs. Give Feedback

NotebookCheck

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."
