Dell Precision 3551 — 15.6" mobile workstation with Quadro graphics
An eight-core Core i7-10875H mobile workstation with 32GB of memory, a 1TB SSD and an NVIDIA Quadro P620. Built for CAD, rendering and heavy data work. 12-month warranty.
Key benefits
-
Eight cores, not four — the i7-10875H has 8 cores and 16 threads, so renders, builds and large datasets finish in a fraction of the time.
-
NVIDIA Quadro P620 4GB — professional graphics certified for the CAD and design applications that will not run properly on integrated graphics.
-
32GB of memory — enough to hold large models, drawings and datasets in RAM instead of paging to disk.
-
1TB solid-state storage — entire project libraries stay local, at SSD speed.
-
15.6" Full HD display — the working area a drawing or a timeline actually needs.
-
Workstation chassis — built to run at load for sustained periods, with the cooling to match.
Performance in use
This is the most capable machine in this group by a wide margin. Eight cores and sixteen threads mean that work which is genuinely parallel — rendering, compiling, simulation, large exports — completes in a fraction of the time a four-core ultrabook takes.
The Quadro P620 is the part that matters for professional software. SolidWorks, AutoCAD, Revit and the Adobe suite are certified against Quadro drivers, and applications that merely tolerate integrated graphics will run properly here. It has 4GB of dedicated memory, so models and textures are not competing with system RAM.
With 32GB of memory and a 1TB SSD, this handles the workloads that make ordinary business laptops struggle: large assemblies, multi-layer drawings, video timelines and datasets that do not fit comfortably in 8 or 16GB. It is heavier than a Latitude, and that is the trade for the performance.

Frequently asked questions
What warranty comes with it?
A 12-month warranty from Reboot IT, covering hardware faults. The battery carries a separate 30-day warranty, as batteries are consumable.
What does "refurbished" mean here?
Every unit is wiped, tested across all major functions, cleaned and graded by our own technicians in Melbourne. It is not a factory-sealed new machine, and it is not sold as one.
Is the battery new?
No. Battery health is measured at testing: 70% or better for Grade A, 50–70% for Grade B. Replacement batteries can be supplied on request.
What is included in the box?
The laptop and a matching power adapter. No original packaging, manuals or accessories unless stated.
How much is shipping?
Free standard AU shipping is included on this item.
What operating system is installed?
Windows 11 Pro is installed and activated, ready for first boot or to join a domain.
Will it run SolidWorks, AutoCAD or Revit?
Yes. The Quadro P620 is a professional card with certified drivers for the major CAD and design applications, and with 32GB of memory and an eight-core i7 this machine is specified above the usual minimums for all three.
Warranty and support
Every machine we sell is professionally tested, cleaned and graded in our Melbourne workshop, and comes with a 12-month warranty from Reboot IT.
