The Eluktronics Mech-15 G3R is a premium-priced laptop that offers high performance for intensive engineering, 3D rendering, and machine learning tasks with its higher-tier graphics card. It has a high refresh rate display, which is great for fast-paced games. However, it's not the most portable option and has a battery life suited for short to mid-duration unplugged use. On the other hand, the Lenovo Legion 5 17" is more affordable and provides good performance for general use and gaming but may falter with more demanding engineering software. It has a larger screen but a lower resolution and refresh rate compared to the Eluktronics. While it’s heavier, which affects portability, it makes up for that with a numpad on the keyboard and additional available ports. Both have a backlit keyboard, support hardware ray tracing, DLSS, and are suitable for gaming; your choice should align with your priority for either higher performance and display quality or a larger screen and cost savings.

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 17 is a current-gen 17-inch gaming laptop and equipped with the latest AMD CPU and a powerful GPU, that manages to reach its full potential. The AMD Ryzen 5 5600H is a very good choice for this laptop and able to maintain its performance level for long periods of time. Our test model only falls behind consistently in a direct comparison with its competitors that are often equipped with eight cores and 16 threads. Despite this, the Legion 5 17 leaves an excellent impression and is almost able to keep up with an Nvidia GeForce RTX 3070 mobile GPU in synthetic benchmarks."
