The Lenovo Legion 7 is somewhat less expensive than the Razer Blade 15 and has a high refresh rate display with decent color accuracy, making it suitable for gaming and general use. However, it is heavier and thicker compared to the Razer Blade 15, which is more portable due to its lighter and thinner design. The Blade 15 also offers a higher screen refresh rate, which is advantageous for fast-paced gaming. Both have similar storage, RAM, and battery capacity. If portability and a higher refresh rate are priorities, consider the Blade 15, but for a more cost-effective option with a solid build and good performance, the Legion 7 is a strong contender.

Andreas Osthoff | September 2022
"The Lenovo Legion 7 is a fast 16-inch gamer with 165 Hz display. The new Lenovo Legion 7 is a very good gaming notebook that, despite its comparatively compact compact 16-inch case, does not have to do without the most powerful components. Thanks to good cooling, no compromises are made in terms of performance. Both the Core i9-12900HX and the GeForce RTX 3080 Ti perform at a very high level."

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."
