If you require a laptop with higher performance for tasks like 3D rendering, machine learning, or engineering software, the Eluktronics Mech-15 G3R stands out due to its more powerful graphics card. However, it is less portable and has a shorter battery life than the Lenovo Slim Pro 9i, which is lighter and more compact, making it more travel-friendly. The Lenovo also boasts a higher quality display with better color range and brightness, excellent for creative work where display quality is crucial. Additionally, if budget is a concern, the Lenovo Slim Pro 9i is the less expensive option with more RAM, aiding in multitasking and complex tasks. The trade-off is that the Lenovo may not perform as well in graphics-intensive scenarios compared to the Eluktronics. Give Feedback

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 Slim Pro 9i is an impressive laptop with a brilliant Mini-LED display, a powerful 100-watt version of Nvidia RTX 4050 graphics, and excellent connectivity. Having run the Cinebench benchmark again, we were impressed with the CPU performance. That makes the Slim Pro 9i is an easy recommendation, especially for those who care about GPU and CPU performance. It’s also a fantastic choice if you frequently view HDR movies and games on your laptop."
