Professional GPU for visual computing

The NVIDIA RTX 4000 Ada 20GB is a workstation graphics card built on the Ada architecture for professional visual computing. It delivers 6144 CUDA cores and 20 GB of GDDR6 memory across a 160-bit interface connected through PCI Express 4.0 x16. The single-slot design suits dense workstations and rack deployments where space is limited. Windows and Linux operating systems are supported for broad software compatibility.

Thermal and power profile

A single-slot cooler manages heat within the constraints of a compact form factor while the card draws power appropriate for professional workloads. Fan speed ramps under sustained compute or render tasks and settles to a low acoustic level during typical desktop or viewport use. The 160-bit memory bus and Ada efficiency help keep power draw proportional to the work performed. Driver controls let users tune thermal targets for quieter or cooler operation as needed.

Build quality and connectivity

Four DisplayPort 1.4a outputs drive multiple high-resolution displays with audio and HDCP 2.2 support for protected content. A dedicated stereo connector enables 3D stereo workflows in compatible applications. GPUDirect for Video and RDMA allow direct data paths between the GPU and capture or storage devices, reducing latency in broadcast and scientific pipelines. Quadro Sync II compatibility adds frame-lock across cards for multi-display installations.

Perguntas sobre este artigo

How do I install the RTX 4000 Ada 20GB in a PCI Express 4.0 x16 slot without bending the single-slot bracket?

Align the card's PCIe 4.0 x16 edge connector with the slot, press straight down until the retention clip clicks, then secure the single-slot bracket with one screw; the common mistake is angling the card during insertion, which can bend the thin bracket or damage the connector.

What maintenance will the 20 GB GDDR6 memory and cooling assembly need over time?

Dust the heatsink fins and fan blades with compressed air every few months; the 20 GB GDDR6 modules are soldered and require no user service, while the fan bearing is sealed and not user-replaceable.

At sustained load, does the 160-bit memory interface or the 6144 CUDA cores hit their limit first?

The 160-bit memory interface typically saturates before the 6144 CUDA cores reach peak utilisation, making memory bandwidth the first bottleneck in prolonged compute or render workloads.
