Dell Precision 3640 review: specs, options & used prices

What this machine is

The Dell Precision 3640 is a workstation desktop, and on the used market it is one of the straightforward ways to get a complete, serviceable computer for a modest sum.

Workstation lines exist for sustained professional loads: server-derived CPU options, high memory ceilings, and a chassis designed to run all day rather than all morning.

Across 3 tracked listings, the median asking price is $280.

Configurations you will actually see

The CPU options we track for the Precision 3640 are the Core i5-10600, Core i7-10700 and Xeon W-1250P. These are 10th-generation Intel Core parts. From the 8th generation on, these generally meet Windows 11 requirements.

Memory options run from 16 GB to 32 GB (16 GB, 32 GB). Even the base 16 GB config is comfortable for typical office and home use; higher tiers are for specialized workloads.

Solid-state storage options include 512GB M.2.

Workstation notes

Workstation configurations target engineering, CAD, rendering and virtualisation workloads that run for hours, not minutes.

Expect higher idle draw and more fan noise than office small-form-factor machines; these were designed to be worked, not to whisper.

Who it fits

It fits engineering, CAD, rendering and pro-workstation roles on a budget — as long as the software tolerates the age of the platform.

Full specifications, current options and tracked prices live on its spec sheet; the desktop catalog and the Dell desktops page help place it among the alternatives.

Verdict

Judged as a tool rather than a toy, the Precision 3640 holds a clear niche at the sensible end of the used market.

Buy it when you need a cheap, repairable machine for its class of work, and verify the configuration before paying — RAM and storage vary widely between listings. Tracked prices span $270 to $460, and most of that spread is configuration, not condition.

Our composite LB Score currently sits at 19/100 — a score that mostly reflects the platform age — use it to compare like with like, not against modern hardware.
