Precision 3650 workstation for professional

The Dell Precision 3650 mid-tower workstation is built for engineers, designers and analysts who need reliable performance for CAD, 3D modelling and financial applications. It ships with Windows 11 Pro and an Intel Core i9-10900K 10-core processor running at 3.70 GHz with a 5.3 GHz turbo frequency. The 32 GB DDR4 2933 memory and 500 GB NVMe SSD provide a responsive platform for daily production tasks.

LGA 1200 platform limits memory and expansion

The system uses the LGA 1200 socket and supports a maximum of 128 GB of DDR4 memory across four slots. The 460 W 80 PLUS Gold power supply and mid-tower chassis constrain the graphics power budget and the number of full-length add-in cards that can be installed. Integrated Intel I219-LM Gigabit Ethernet and Realtek ALC3246 audio handle networking and sound without additional cards.

Quadro P620 2 GB GDDR5 suits entry 3D workloads

The Nvidia Quadro P620 with 2 GB GDDR5 memory on a 128-bit bus and four Mini DisplayPort 1.4 outputs drives multi-monitor setups for 2D drafting and light 3D visualisation. It is not suited for heavy GPU rendering, large-model simulation or compute workloads that need more video memory or higher memory bandwidth. Buyers needing greater graphics performance should choose a workstation with a higher-tier professional GPU.

Questions about this item

Should I choose the 32 GB DDR4 2933 MHz configuration or add more memory up to the 128 GB maximum?

The system ships with 32 GB as four 8 GB DDR4 2933 MHz modules and supports up to 128 GB total, so you can add three more 8 GB sticks later if workloads demand it.

What does the 5.3 GHz turbo on the 10-core i9-10900K deliver in actual workloads?

The 10-core i9-10900K runs at 3.70 GHz base and can boost to 5.3 GHz on active cores, giving strong single-thread speed for CAD and snappy multi-thread throughput for rendering.

What display outputs does the Quadro P620 2 GB GDDR5 provide and what resolution does mDP 1.4 cap at?

The card has four mini-DisplayPort 1.4 connectors, each driving up to 4K at 60 Hz or 5K at 60 Hz with DSC, so you can run four 4K monitors simultaneously.
