This video compares Dell Precision desktop workstations for SOLIDWORKS and CAD workflows, focusing on real-world performance rather than theoretical specs. We benchmark the Precision 3660, 5860, and a 4-year-old 3000 series system across tasks like opening large assemblies, part rebuilds, simulations, and CFD analysis. Results show the 3660 delivering the fastest performance for core CAD and multi-threaded workloads, outperforming even higher-tier models in most tests. We also discuss when 5000 and 7000 series systems make sense for rendering, AI, and heavy simulations. If you want the best balance of speed and value for CAD and CAE, this review is essential.
