About the Lenovo ThinkSystem NVIDIA RTX 4000 Ada 20GB PCIe GPU

The Lenovo ThinkSystem NVIDIA RTX 4000 Ada Generation 20GB PCIe GPU (4X67A84446) is built on NVIDIA's Ada Lovelace architecture, delivering professional-grade graphics and compute performance engineered for enterprise servers and workstations. Featuring 6,144 CUDA cores, 192 third-generation Tensor cores, and 48 fourth-generation RT cores, it is designed to accelerate demanding visualization, AI inferencing, and simulation workloads within ThinkSystem server environments.

With 20GB of GDDR6 ECC memory on a 160-bit memory bus, the RTX 4000 Ada provides substantial frame buffer capacity for large datasets, complex 3D scenes, and concurrent virtual workstation sessions. The card supports PCIe 4.0 x16 connectivity and operates within a 130W TDP envelope, making it suitable for rack-mounted server deployments where power and thermal budgets are tightly managed. Hardware-accelerated ray tracing and DLSS 3 capabilities further extend its utility across real-time rendering and AI-enhanced visual computing tasks.

As a Lenovo ThinkSystem-validated component, the RTX 4000 Ada carries full firmware and driver compatibility guarantees within Lenovo's server ecosystem, simplifying integration into managed datacenter infrastructure. It is well-suited for organizations deploying virtual desktop infrastructure (VDI), AI-assisted design pipelines, scientific visualization, and edge AI inference at scale, where a balance of GPU compute density, memory capacity, and power efficiency is essential.

Ideal for

  • Virtual Desktop Infrastructure (VDI) hosting multiple high-fidelity GPU-accelerated remote workstation sessions simultaneously
  • AI inferencing at the edge or in the datacenter for computer vision, natural language processing, and recommendation models
  • Professional 3D rendering and real-time visualization for CAD, BIM, and product design workflows in enterprise environments
  • Scientific and engineering simulation including CFD, FEA, and molecular dynamics requiring large on-GPU memory capacity
  • Medical imaging processing and AI-assisted diagnostics leveraging ECC memory for data integrity in clinical deployments
  • GPU-accelerated media transcoding and streaming production workflows within broadcast or enterprise media infrastructure

Frequently Asked Questions about Lenovo ThinkSystem NVIDIA RTX 4000 Ada 20GB PCIe GPU

What server platforms accept the Lenovo ThinkSystem NVIDIA RTX 4000 Ada 20GB PCIe GPU?

Reference servers include Dell PowerEdge XE9680 / XE9712, HPE Cray XD670, Lenovo ThinkSystem SR685a / SR675 V3, Supermicro AS-A21GE / SYS-821GE, Gigabyte G593 / G894, ASUS ESC. Share your target platform in the RFQ and we will confirm chassis-to-GPU compatibility and recommended NIC pairing.

How long is the lead time on AI GPUs?

Highly model-dependent. L40S / RTX-class: typically 3-6 weeks. H100/H200/B200 in SXM form factor: 12-16 weeks for whole-platform allocations. We quote genuine-channel ETAs only — no grey-market promises.

Do you supply matched networking (Quantum InfiniBand / Spectrum-X)?

Yes — Omnixon stocks the full NVIDIA networking lineup (Quantum-2 / Quantum-X InfiniBand, Spectrum-X Ethernet, ConnectX NICs, BlueField DPUs) so we can quote a complete training-cluster BOM, not just the GPUs.

Can you help with NVIDIA AI Enterprise licensing?

Yes. We hold genuine-channels for NVIDIA AI Enterprise software subscriptions. Add it to your RFQ and we quote node-aligned licensing along with the hardware.
