Compact workstation for professional workflows

This Lenovo ThinkStation Mini desktop pairs a 14th Gen Intel i9-14900 processor with an NVIDIA T400 4GB GDDR6 graphics card. The 24-core, 32-thread CPU reaches 5.8 GHz for demanding compute tasks. Windows 11 Home is pre-installed on a 256GB PCIe NVMe SSD. It targets professionals who need certified application stability in a 7 x 7.25 x 1.5 inch chassis.

GPU memory dictates model fidelity

The T400 provides 4GB of GDDR6 video memory connected via a PCI Express x16 interface. This capacity handles moderate 3D assemblies, multi-display CAD viewports and light GPU compute workloads. Larger textures, complex simulation datasets or high-resolution rendering queues will exceed the frame buffer and force system memory fallback.

8GB DDR5 suits essential multitasking

The single 8GB DDR5 SO-DIMM runs the OS, office suite and one professional application comfortably. Opening large datasets, running virtual machines or keeping multiple creative projects open simultaneously will saturate the memory. The 300W power supply and mini form factor limit further internal expansion.

Questions about this item

What does the 24-core, 32-thread i9-14900 mean for real workloads?

The 14th Gen i9-14900 has 8 performance cores and 16 efficient cores, reaching 5.8 GHz boost. It handles heavy multi-threaded tasks like rendering or compilation while background processes run on the efficient cores.

What does the PCI Express x16 link for the T400 actually deliver?

The NVIDIA T400 4GB GDDR6 connects over PCI Express x16, giving full bandwidth for professional 3D viewport work and multi-display output across HDMI, DisplayPort and three mini-DisplayPort connectors.

Will the 7 × 7.25 × 1.5 inch chassis fit behind my monitor?

At 3.1 lb and only 1.5 inches tall, the mini PC slides onto a VESA mount or sits on a desk shelf. The 300 W supply is internal, so there is no external brick to hide.
