The Eluktronics Mech-15 G3R offers high performance for intensive gaming and tasks like 3D rendering and engineering thanks to a potent processor and advanced graphics. However, it's heavier and has shorter battery life compared to the Lenovo. The Lenovo IdeaPad Slim 7i Pro is more affordable, lighter for greater portability, and has a longer battery life, making it well-suited for general use, though it's less powerful for demanding tasks and lacks dedicated gaming features. Both feature high-quality keyboards, numerous ports including Thunderbolt, and are equipped with Windows 11 Home, but the Eluktronics has added gaming-oriented capabilities such as ray tracing and DLSS support.

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."

Allen Ngo | October 2021
"The main selling point of the IdeaPad Slim 7i Pro versus a regular IdeaPad Slim 7 is its faster Core H-series CPU. In reality, the Core i7-11370H is only marginally faster than the U-series Core i7-1165G7 to the point where most users are not likely to notice the benefits. The slight performance uptick comes at the cost of slightly higher power consumption as well meaning owners will have to deal with potentially warmer temperatures or louder fans to compensate. Unless if you happen to be a power user, then the regular non-Pro model will be more than enough. Once you go 90 Hz, you can't go back."
