Compact workstation for professional workloads

The Lenovo ThinkStation Mini pairs a 14th Gen Intel Core i9-14900 processor with 24 cores and 32 threads with an NVIDIA T400 graphics card offering 4GB of GDDR6 memory. It ships with 8GB of DDR5 SO-DIMM memory and a 2TB PCIe NVMe SSD, all powered by a 300W supply. Windows 11 Pro is pre-installed on this 7 x 7.25 x 1.5 inch chassis.

Suited for multi-threaded applications

The 36MB cache and high core count handle rendering, compilation and data analysis, while the T400 drives up to four monitors via one DisplayPort, three mini-DisplayPorts and HDMI. WiFi 6 and Bluetooth 5.3 provide modern wireless connectivity. Buyers needing more than 8GB of system memory or a higher-wattage power supply for larger GPUs should consider other configurations.

8GB DDR5 and 2TB NVMe deliver responsive everyday

The current memory capacity supports typical office suites, development environments and light creative tasks without paging. The 2TB solid-state drive holds large project libraries and OS images with ample headroom. Memory-intensive workloads such as heavy virtualisation or large dataset processing will exceed the installed 8GB, and the 300W PSU limits further internal expansion.
