Dell Precision 3581 15.6" Mobile Workstation — i9, 64GB, RTX 2000 Ada
This is the Precision 3581 at the top of its range. A 14-core Core i9-13900H, 64GB of memory, a 1TB NVMe SSD and an NVIDIA RTX 2000 Ada Generation professional graphics card with 8GB of GDDR6, behind a Full HD touchscreen. The RTX 2000 Ada is a current-generation professional GPU — a substantial step above the entry-level workstation cards usually found in a 15.6-inch chassis — and with 64GB of memory alongside it, this machine takes on work that would normally need a desktop.
Key Benefits
- NVIDIA RTX 2000 Ada Generation with 8GB GDDR6 — a current-generation professional graphics card
- Intel Core i9-13900H, 14 cores, the fastest processor offered in this chassis
- 64GB of memory — desktop-class capacity for very large models and datasets
- 1TB NVMe SSD, so large projects live on the machine rather than on an external drive
- 15.6-inch Full HD (1920x1080) touchscreen at 250 nits, with a backlit keyboard
- Factory-fitted 4G LTE modem (Intel XMM 7560R) — add a data SIM and work anywhere
- Intel vPro for remote management, and an infrared camera for Windows Hello face sign-in
Performance
Very little in a 15.6-inch chassis is specified like this. The RTX 2000 Ada has 8GB of dedicated memory and current-generation Ada architecture, which means it handles large CAD assemblies, GPU rendering and real-time visualisation rather than merely running the software. The Core i9-13900H supplies 14 cores of sustained processing for renders, simulations and compiles, and 64GB of memory removes the ceiling that forces most laptops to swap to disk. The 1TB NVMe SSD means project files, libraries and virtual machines can all sit locally.

Frequently Asked Questions
How much faster is the RTX 2000 Ada than an entry workstation card?
Considerably. It has 8GB of dedicated memory against 4GB on entry cards, and a current-generation Ada architecture, so it handles larger models and GPU rendering rather than just displaying them.
Is 64GB of memory excessive?
Not for large assemblies, point clouds, video projects or several virtual machines at once. For general office work it is far more than you need.
Can this replace a desktop workstation?
For most professional work, yes. Add an external monitor, keyboard and mouse and it will do the job of a desktop while still travelling when you need it to.
Does it come with a charger?
Yes, a compatible power adapter is included. This configuration uses a higher-wattage adapter, so please use the one supplied.
Is Windows included and activated?
Yes. Windows 11 Pro is installed and activated.
Do I need a special SIM for the 4G?
No. The laptop takes a standard Australian data SIM. You will need a data plan; the SIM itself is not included.
