About Us · Contact Us · Editorial Team · Advertising · Privacy Policy · Subscriber Services · © 2026 Digital Engineering 24/7 · It’s been nearly three years since we last reviewed a Dell Precision workstation, and needless to say, a lot has changed in that time. This time around, the Dell Precision T3500 that we received is powered by one of the latest Xeon processors, based on Intel’s Nehalem microarchitecture. Midrange performance Dell included two identical hard drives, so we could perform benchmark tests under both Windows XP and Windows Vista, and all of the results were very respectable. The Dell Precision T3500 easily outperformed older systems, although it lagged somewhat behind the most recent workstations we’ve looked at from HP and Lenovo, owing to Dell’s decision to send us a somewhat slower CPU and graphics accelerator. The same proved true for the AutoCAD rendering test—although here, thanks to hyper-threading, the results were still quite respectable. With eight threads, the Dell Precision T3500 took exactly twice as long to complete the rendering as the faster HP workstation, which benefited from the equivalent of 16 simultaneous processes.
