The Dell Inspiron 15 3520, being budget-friendly, is suitable if you need a laptop for general use and want to save money, with moderate battery life and a standard Full HD screen. However, for more demanding tasks like 3D rendering, machine learning, or gaming, the Eluktronics RP-15, while more expensive, offers significantly better performance due to its advanced processor and graphics card, higher resolution display, and larger battery capacity—it also features hardware ray tracing for enhanced gaming visuals and a higher refresh rate screen for smoother motion. The RP-15 is heavier, though, impacting its portability compared to the lighter Inspiron. Give Feedback

PCMag

Mark Knapp | January 2023
"Dell's Inspiron 15 (3525) is a peppy-enough and affordable-enough home or remote work machine, but it's not very ambitious; it does little to go beyond the basics. More the concern: It’s readily overshadowed by a number of machines that outperform and outclass it. Even if the Inspiron can get the job done today, its competition has the mettle to keep doing the job tomorrow in a way the Inspiron simply can’t promise. Plus, those alternatives are much more enjoyable after work."

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."
