Our Verdict

HP ZBook Firefly 15 G8 (2021)

Dell Precision 3571 (2022)

The HP ZBook Firefly 15 G8 (2021) and the Dell Precision 3571 (2022) are both mobile workstations; however, they're very different. The HP prioritizes portability and general user experience over sheer performance, while the Dell laptop prioritizes performance over user experience. If performance isn't the most important aspect and you just want a portable laptop with a comfortable keyboard or better-sounding speakers, go with the HP. However, if performance is the most important aspect, go with the Dell, as its Intel 12th Gen processors and NVIDIA discrete graphics are significantly more powerful.
