If performance during intensive engineering tasks is a priority and you require specialized features like hardware ray tracing and higher color accuracy for professional work, the Dell Precision 5470 is geared towards such requirements, though it comes at a higher price. On the other hand, the Lenovo Legion Slim 7 offers good general use and gaming performance due to a more powerful GPU, and it is more affordably priced, but it lacks some of the professional features found in the Dell. The Dell is also slightly more portable due to its smaller size and lower weight, while both laptops have similar battery life. Give Feedback

PCMag
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 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."
