The Dell Precision 5470, at a higher price, offers a portable design, professional build, and adequate performance for engineering tasks; however, its smaller storage may limit data-heavy applications. The Lenovo Legion Slim 7, less expensive and with more storage, provides better performance for 3D, gaming, and intensive workloads due to its powerful graphics, but it is slightly heavier which affects portability. The Lenovo also has a higher resolution and refresh rate display, which is better for visual tasks but may reduce battery life compared to the Dell's more modest display. Give Feedback

The Lenovo Legion Slim 7 has a better screen than the Dell Precision 5470 for general use, gaming and AI, engineering and design, content creation, and software development.
The Dell Precision 5470 has a display that provides clear images and vibrant colors suitable for professionals in engineering and design due to its high resolution and a wide color gamut, which ensures accuracy when working with detailed visual content. However, for gaming and 3D work, it falls short because it lacks a high refresh rate, making it less smooth for fast-paced visuals which are crucial in those fields. The Lenovo Legion Slim 7, while sharing a similar high-resolution panel and rich color coverage for precise design tasks, isn't optimal for gaming either due to a refresh rate that's not tailored for the fast action seen in many modern games.

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."
