The Eluktronics Mech-15 G3R is a more expensive option with a powerful graphics card suitable for intensive gaming, demanding engineering software, and 3D or machine learning tasks. On the other hand, the Lenovo Legion Slim 7 16" is less expensive and offers a slightly larger screen with a higher aspect ratio, which could be more suitable for productivity and media consumption. The Legion is also a bit lighter and thinner, making it more portable. Both have ample storage and memory, but the Eluktronics has a better battery life, making it more suited for use away from a power source. If budget is a concern and portability is key, the Lenovo might be a better choice, while the Eluktronics is suited for users looking for top-tier performance in games and professional applications.

The Lenovo Legion Slim 7 has a better screen than the Eluktronics Mech-15 G3R for general use, gaming and AI, and engineering and design.
For general use, both the Eluktronics Mech-15 G3R and Lenovo Legion Slim 7 have high-resolution panels with good brightness, delivering sharp and clear visuals that make reading text and browsing the web enjoyable. In engineering and design work, the importance of accurate colors is met by both laptops, offering wide color gamuts that ensure designers see precise hues as intended for their projects. However, when it comes to gaming and 3D applications, the lower refresh rates of these screens might not provide as fluid motion as other laptops designed specifically for those tasks, which can diminish the overall experience.

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 Slim 7 is a slim Legion notebook that is just as excellent with Nvidia & Intel. However, the Legion Slim 7i slightly sullied by lacklustre battery life. You get a slim aluminium chassis, great input devices, decent port selection, fast high-quality WQXGA display and great performance. Supporting Thunderbolt 4 is one advantage of the Intel/Nvidia model tested in this review. Moreover, this variant has slightly higher CPU performance as well as better GPU performance in certain applications (e.g. CUDA-based apps). The Lenovo Legion S7i is thin, premium and performant – but less efficient than its AMD counterpart."
