NVIDIA T400 4GB Professional GPU

Driving multiple high-resolution displays from a small, efficient card. It supports up to four 5K monitors, or 8K output, from a low-profile, single-slot, 30W card, which makes it the natural choice for multi-display professional workstations, trading and monitoring walls, control rooms, digital signage, and CAD or design setups where the need is many sharp displays rather than heavy compute.

No, and this is the clearest case in the lineup. With 384 CUDA cores and 1.094 TFLOPS, the T400 is an entry display and light-graphics card, not a compute or AI GPU. It cannot train or meaningfully serve AI models. For AI work, the catalog's A10 (inference and VDI) and the Hopper and Blackwell systems (training) are the right tools, and the Ada professional cards for workstation compute and rendering.

Up to four displays at 5K resolution, with support for output up to 8K (7680 x 4320) at 60Hz. That multi-display capability from a single small, low-power card is the T400's core strength, and the reason it is chosen for multi-monitor productivity, financial and monitoring walls, and control-room setups.

2D work, light 3D, design and CAD model viewing, video playback, and general multi-display productivity, comfortably. What it is not for is heavy 3D rendering, simulation, or compute, its 384 CUDA cores and 4GB of memory are sized for display and light graphics, not for those workloads. Match it to display-and-light-graphics needs and it does its job well.

It lets the T400 run in almost any system without a supplemental power connector, including compact, small-form-factor, and low-power workstations. Combined with the low-profile single-slot form, that efficiency is why the T400 fits where larger cards cannot, and why it suits dense multi-workstation or signage deployments where power and space add up.

384 CUDA cores, 4GB of GDDR6 on a 64-bit interface, 80 GB/s memory bandwidth, 1.094 TFLOPS of FP32, PCIe 3.0 x16, up to four 5K displays or 8K output, and 30W maximum power, in a low-profile single-slot form. MillionMiner confirms the card in the quote.

It is the entry floor. The Ada professional cards (RTX 2000 through 5000 Ada) offer far more compute and memory for rendering and design work; the A10 is a data center inference and VDI card; the Hopper and Blackwell systems are for AI. The T400 is below all of them on compute, and chosen specifically when the need is many displays and light graphics in a tiny, efficient, affordable card. MillionMiner matches the card to your actual workload.

Yes, it is part of NVIDIA's professional line with certified drivers, which gives professional 2D and 3D applications the validated stability they expect. For multi-display professional productivity and design viewing, that certification and driver support are part of its value over a consumer card.

As a current entry-level professional card, the T400 is typically available new. MillionMiner confirms the card and its condition in the quote and verifies every unit before shipment. If you need a specific quantity for a multi-workstation or signage rollout, that is sized in the quote.

Submit your requirements, display count, workstation type, and quantity, through the quote form. A MillionMiner specialist confirms the card, quantity, and any multi-display or multi-workstation considerations, with delivery. Every unit is tested before shipment and shipped worldwide DDP with duties handled, and the specialist will tell you honestly if a higher card or different hardware better fits your workload.
