Cisco UCSC-GPU-H200-NVL | H200 NVL GPU, 141GB HBM3e, 4.8TB/s, 600W PCIe 5.0

Q: What types of workloads is the H200 NVL optimized for?
A: The H200 NVL is optimized for AI training and inference, large language models like GPT and Llama, generative AI applications, scientific simulations, high-performance computing, and memory-intensive deep learning workloads. Its 141GB HBM3e memory enables processing of massive datasets and large-scale models that exceed traditional GPU memory limits.

Q: How does the H200 NVL differ from the H200 SXM variant?
A: The H200 NVL is a PCIe 5.0 add-in card with 600W TDP, designed for air-cooled enterprise racks and standard server hardware. The H200 SXM5 variant uses SXM5 packaging with higher TDP, typically requires liquid cooling, and is optimized for HGX/DGX systems with NVSwitch fabric. Both share the same GH100 die and 141GB HBM3e memory subsystem.

Q: Can the H200 NVL be used in multi-GPU configurations?
A: Yes, the H200 NVL supports NVLink bridge connectors enabling 2-way or 4-way GPU configurations with 900GB/s bidirectional bandwidth per GPU. This allows up to four GPUs to work together for accelerated large language model inference and HPC applications, providing up to 1.7x faster LLM performance and 1.3x better HPC performance compared to H100 NVL configurations.

Q: Is the H200 NVL compatible with existing H100 or A100 infrastructure?
A: Yes, the H200 NVL PCIe card maintains backward compatibility and is a drop-in replacement for H100 and A100 GPUs in existing systems. It uses the same PCIe 5.0 interface and works with NVIDIA's full software stack including CUDA, cuDNN, and TensorRT, enabling seamless upgrades without infrastructure changes.

Q: What cooling requirements does the H200 NVL have?
A: The H200 NVL is designed for air-cooled enterprise rack environments and operates at 600W TDP with configurable power profiles down to 450W for constrained thermal environments. This makes it suitable for standard data center deployments with proper ventilation, unlike the SXM5 variant which typically requires liquid cooling.
