If you prioritize performance in intensive tasks such as 3D rendering, machine learning, or engineering programs, the MSI Stealth may justify the higher price, but it's less portable than the Razer Blade 15, which offers a balance of performance and portability for general use and gaming. The Razer may have better battery life, making it more suitable for on-the-go use, while the MSI is typically chosen for its superior processing capabilities which can be more demanding on battery consumption. Consider the primary use and whether it's worth trading off portability and battery life for higher performance in specialized tasks. Give Feedback

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."
