Nvidia Quadro M620 — ISV-Certified for CAD and 3D
The Nvidia Quadro M620 is a professional-grade discrete GPU with ISV certifications for leading CAD and 3D applications including AutoCAD, SolidWorks, Revit and CATIA. Unlike consumer GeForce graphics cards, Quadro drivers are validated by software vendors for stability and precision in professional workflows. With 16GB DDR4 RAM and a fast 512GB SSD, the Precision 3520 handles large CAD assemblies, complex 3D models and data-intensive professional workloads with confidence.
Casual Gaming — What This Laptop Can Run
The Nvidia Quadro M620 is equivalent in gaming performance to approximately a GeForce GTX 950M — making it more capable for gaming than many entry-level discrete GPUs. Combined with the Core i7-7820HQ and 16GB RAM, the following popular titles run comfortably at low to medium settings:
- Minecraft (Java Edition) — High settings
- League of Legends — Medium to High settings
- Dota 2 — Medium settings
- CS:GO — Medium settings
- Fortnite — Low to Medium settings
- Rocket League — Medium settings
- GTA V — Low settings
- FIFA 18/19 — Medium settings
- Stardew Valley — High settings
- Among Us — High settings
- Roblox — Medium to High settings
- Age of Empires II: Definitive Edition — Medium settings
Note: Modern AAA titles released after 2020 are not recommended on this GPU. This machine is best suited to casual, indie and older game titles.
Core i7-7820HQ and Full Workstation Connectivity
The Intel Core i7-7820HQ is a true quad-core 45W-class processor running up to 3.9GHz — a step above the lower-power ULV Core i5/i7 U-series found in ultrabooks, delivering sustained performance for demanding workloads. Thunderbolt 3 via USB-C enables single-cable docking, 4K display output and 40Gbps data transfer. HDMI and VGA both allow direct monitor connection. Three USB-A 3.0 ports, SD card reader and built-in Gigabit Ethernet round out a comprehensive port set rarely found in slim modern laptops.
Who Is This For?
The refurbished Dell Precision 3520 is ideal for CAD engineers, architects and designers who need an ISV-certified Quadro GPU for AutoCAD, SolidWorks or Revit; data professionals who need a powerful quad-core workstation with 16GB RAM and 512GB storage; and casual gamers who want a capable machine for older and indie titles without paying gaming laptop prices.
