Overview

T400 is an NVIDIA GPU entry in the Quadro RTX family. It is listed with Turing architecture and TU117 silicon.

Key reference data: 384 CUDA cores/shaders, 2 GB GDDR6 memory, 64-bit memory bus, 30 W board power class.

Board-partner cards can vary in cooler, PCB, display outputs, clocks, BIOS behavior, and power connector layout.

Why It Mattered

T400 represents the professional side of Quadro RTX and the Turing generation around 2021. Certified-driver workflows, VRAM configuration, display outputs, and OEM workstation compatibility are the main historical reasons to track it separately from consumer GeForce models.

Collector Notes

For archival use, record the OEM or board-partner part number, bracket height, cooler type, memory configuration, display-output adapter or breakout cable, firmware, certified-driver branch, and the workstation model where the card was used.

Used-Market Caution

Before buying used, confirm bracket height, display adapters, mini-DP or DMS breakout cables, fan condition, VRAM errors, driver branch support, OEM firmware quirks, and whether the card needs workstation-specific airflow or auxiliary power.
