The Eluktronics RP-15 is a bit more expensive and excels in 3D tasks and engineering work, thanks to its superior GPU. It also has a higher resolution display but is a bit heavier, making it less portable. The Lenovo Legion Slim 7, on the other hand, is a bit less costly, lighter, and has longer battery life, which enhances its portability. Its GPU is less powerful, affecting performance in intensive gaming or professional applications, but it boasts better build quality and portability, making it suitable for everyday use and travel. Consider your primary need: if it's performance for demanding tasks, go for the RP-15; if you prioritize portability with adequate performance for general use, choose the Legion Slim 7. Give Feedback

The Eluktronics RP-15 has a better screen than the Lenovo Legion Slim 7 for general use, gaming and AI, and engineering and design.
The Eluktronics RP-15's display, with its higher resolution, makes for sharp and clear image quality, crucial for general use and detailed engineering work, and its color accuracy benefits professional design tasks. However, the relatively lower refresh rate can detract from the smooth visuals demanded in gaming and 3D applications. In contrast, the Lenovo Legion Slim 7's screen, while offering good resolution and fine color representation for everyday tasks and precision work, also falls short for gaming and 3D content due to its limited refresh rate.

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."

Benjamin Herzig | November 2022
"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."
