For intensive tasks like gaming or engineering software, the Eluktronics Mech-15 G3R will offer better performance, but it comes at a higher cost. The Lenovo Legion 5 15", while more affordable, may have slightly lower performance. If you often travel or move around, the Legion 5 may be a better option due to possibly better battery life and portability. On the other hand, if you require the highest possible performance for tasks like 3D modeling or machine learning and can afford the price, then the Mech-15 G3R is a strong choice. Remember that the higher performance may also mean a heavier laptop with less battery life. Consider how much you value performance over cost, portability, and battery life when making your decision.

The Eluktronics Mech-15 G3R has a better screen than the Lenovo Legion 5 15" for gaming and AI, engineering and design, software development, and content creation.
For general use, a laptop with a high-resolution, bright display with a good panel type ensures crisp text, vivid images, and comfortable viewing, which both the Eluktronics Mech-15 G3R and Lenovo Legion 5 15" offer. Engineering and design work benefits from accurate color reproduction, where the Eluktronics may have the edge with superior color gamut coverage, essential for tasks that demand color precision. Meanwhile, gaming and 3D applications require smooth motion, provided by high refresh rates, where both laptops fall short, making them less suitable for fast-paced, visually intensive games or 3D rendering that benefit from quick screen updates.

Aaron Ritchie | September 2022
"Everything considered, the XMG Neo 15 (Mech-15 G3R) with RTX 3070 Ti is a great gaming performer. The combination of the Ti graphics card with the new Intel 12th gen CPU is enough to go toe-to-toe, and even slightly pull ahead of the RTX 3080 in most titles, though on games with Ray-Tracing enabled, particularly with graphics set to the maximum and on higher resolutions, the additional VRAM of the RTX 3080 makes a big impact, and the 8GB RTX 3070 Ti machine simply can’t compete, even with the more powerful processor."

"The Lenovo Legion 5 15 is an affordable gaming laptop with a lot of power. The new AMD processor Ryzen 7 5800H offers plenty of performance and it is also very efficient. The combination with the fast 130W version of the GeForce RTX 3060 ensures high gaming performance. We also like the fast 165 Hz display with the 1080p resolution. The automatic graphics switching causes some problems with stutters, which are very annoying. If you do not need long battery runtimes, you should definitely deactivate the hybrid graphics mode in Lenovo's Vantage app. The Legion 5 15 is never silent."
