The Lenovo Legion 7i Pro offers a more powerful processor and higher-end graphics card than the Razer Blade 15, making it a better option for intensive engineering tasks, 3D rendering, machine learning, and gaming. However, the Razer Blade 15 is lighter and offers a higher portability score, making it more suited for those who prioritize ease of carrying their laptop around. Both have great build quality, good keyboards, and similar battery life for typical usage. If you need higher performance for demanding applications, the Lenovo is a strong choice, but if portability and a slightly more premium laptop appearance matter more, consider the Razer Blade 15.

The Lenovo Legion Pro 7i is very good for general use, while the Razer Blade 15 is good.
The Lenovo Legion 7i Pro's top-tier CPU and ample RAM make it standout for demanding tasks and multitasking, plus its high-resolution, high-brightness screen is great for viewing content, yet it's heavier and has decent battery life, making it less ideal for on-the-go usage. In contrast, the Razer Blade 15 is more portable with its lighter frame and better battery life, but it trades off some performance with a lower-tier CPU and half the memory, although it still has a quality screen and solid build, making it a good option for general use with added mobility.

The Lenovo Legion Pro 7i is excellent for engineering and design, while the Razer Blade 15 is very good.
The Lenovo Legion Pro 7i stands out for engineering and design use due to its more powerful Intel i9 processor, higher RAM capacity, and superior Nvidia RTX 4080 graphics card, which are critical for running intensive applications smoothly. While the Razer Blade 15 is very capable with its Intel i7 processor and Nvidia RTX 3070 Ti graphics, it is more portable and offers better screen color accuracy, but for raw performance in engineering tasks, the Legion Pro 7i takes the lead.

The Lenovo Legion Pro 7i has a better screen than the Razer Blade 15 for general use, gaming and AI, engineering and design, software development, and content creation.
For general use, both the Lenovo Legion Pro 7i and Razer Blade 15 offer clear, vivid displays with sharp resolutions and high brightness, which contribute to crisp text and vibrant images that are easy on the eyes. When considering engineering and design, these laptops' screens display a wide range of colors accurately, essential for tasks requiring precise color work such as photo editing or CAD. However, for gaming and 3D applications, their screens fall short because they do not refresh as quickly as gaming-optimized laptops, leading to less fluid motion and potential visual delays in fast-paced scenarios.

"Passionate gamers who want to play demanding modern titles with maximum details and don't mind spending the moolah will find the Lenovo Legion 7 Pro to be the right choice. The bright, sharp, and color-accurate 16:10 QHD 240 Hz display makes for an immersive viewing experience. The hardware is housed in a stylish chassis that feels premium and scores well in terms of workmanship and stability. Other aspects such as sound quality, input devices, and connectivity also seem to be near-perfect."

"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."
