About the Gigabyte NVIDIA RTX 4000 Ada 20GB GDDR6 PCIe Low-Profile GPU
The Gigabyte NVIDIA RTX 4000 Ada 20GB GDDR6 PCIe Low-Profile GPU (part number GV-N4KRTXA-20G) combines space-efficient low-profile form factor design with powerful Ada Lovelace architecture, making it ideal for dense server deployments where thermal efficiency and compact installation matter. Gigabyte's engineering delivers 6,144 CUDA cores, 192 third-generation RT cores, and 192 fourth-generation Tensor cores paired with 20 GB of GDDR6 ECC memory across a 160-bit bus, achieving 360 GB/s memory bandwidth. The single-slot bracket and 130 W TDP allow seamless integration into standard PCIe 4.0 x16 slots using just one 6-pin power connector, eliminating the need for specialized power infrastructure upgrades.
This GPU supports ECC memory for mission-critical workloads, NVIDIA vGPU virtualization, and reaches a boost clock of 2505 MHz. Native support for DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.3 ensures broad application compatibility. Four DisplayPort 1.4 outputs enable 8K resolution workflows at 7680 x 4320. AI infrastructure teams, data center engineers, and IT procurement professionals choosing Gigabyte hardware gain a professional-grade accelerator that balances performance, reliability, and thermal efficiency for visualization, AI inference, and scientific computing in space-constrained environments.
Primary Use Cases
- Medical imaging and diagnostic visualization requiring ECC memory stability and 8K output capability

Frequently Asked Questions about Gigabyte NVIDIA RTX 4000 Ada 20GB GDDR6 PCIe Low-Profile GPU
What server platforms accept the Gigabyte NVIDIA RTX 4000 Ada 20GB GDDR6 PCIe Low-Profile 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.
