If portability and screen quality are important to you, the Lenovo Slim Pro 9i stands out with a higher resolution and brighter display suitable for a wide range of color-critical tasks, while also being lighter and thinner. On the other hand, if you're more concerned with gaming and engineering work, the Eluktronics RP-15, while heavier, has a more potent graphics card and higher performance scores in those areas. Both laptops have high-quality keyboards and build, but if budget is a concern, the RP-15 is less expensive. Keep in mind that while the Slim Pro 9i has longer battery life, the RP-15 offers an RGB keyboard and hardware suited for ray tracing in gaming. Give Feedback

Eber Anthony | October 2020
"To conclude, I’m genuinely impressed with Eluktronics and what they have been able to deliver with the RP-15. You see this is all about maximizing performance, cooling, and giving users the most flexible I/O, and then wrapping it into a chassis that doesn’t feel super cheap. Let’s also not forget the price point, I think they have really nailed it in that department."

"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."
