When deciding between the Dell Precision 5470 and the Lenovo Legion Slim 5i, consider your primary use case. The Dell, with its professional-grade GPU and certification for engineering software, suits intensive engineering and professional workloads, but may cost more and has less storage. In contrast, the Lenovo, sporting a more powerful gaming-oriented GPU and a higher resolution display, is tailored towards gaming and multimedia tasks, supports high-refresh-rate experiences, and comes with a larger storage capacity, albeit with a shorter battery life and higher weight, potentially reducing its portability. Choose the Dell for specialized work and travel friendliness, or the Lenovo for gaming and media, accepting the tradeoff in portability and battery duration. Give Feedback

The Lenovo Legion Slim 5i is very good for gaming and AI, while the Dell Precision 5470 is only fair.
The Lenovo Legion Slim 5i offers a superior gaming and 3D experience due to its more powerful Nvidia RTX 4060 GPU and a much higher screen refresh rate than the Dell Precision 5470, which comes with an Nvidia RTX A1000 GPU and a standard refresh rate.

Brian Westover | August 2022
"The Dell Precision 5470 is a mobile workstation that's far more portable than most alternatives. Between its slim 14-inch design and top-quality MIL-STD 810H build, it's one of the best options around for taking professional-grade performance on the road or to the job site. There are tradeoffs for its portability, and users of the most demanding, graphics-intensive applications will need to carry something heavier. But the Dell's exceptional battery life underscores its desirability as the most portable workstation we've seen."

"The Lenovo Legion Slim 5 Gen 8 acknowledges that a gaming laptop doesn’t have to be as thick as possible and can still ensure adequate cooling when the muscles need flexing. To this end, in the Slim 5 Gen 8, it finds a neat balance of refined, trimmed-down design that still lets its internals cruise (even above their max power ratings). Lenovo then added in some high-end build quality with an altogether excellent keyboard that’s useful for both work and play."
