Mellanox Network Cards
Overview
Product sourcing insights & recommendations
The market for Mellanox (NVIDIA) network cards is currently undergoing a significant generational shift driven by the massive I/O demands of AI and Large Language Model (LLM) training. As NVIDIA integrates Mellanox technology deeper into its AI ecosystem, the product roadmap has evolved from traditional high-speed networking to AI-optimized SuperNICs.
Market Trends & Generation Insights
* ConnectX-8 (XDR/800G): The emerging standard designed for NVIDIA Blackwell clusters. It introduces the "SuperNIC" category, offering 800 Gb/s throughput and advanced hardware-based congestion control to manage "east-west" GPU traffic. Lead times are currently the longest, often exceeding 20 weeks for enterprise buyers NaddodFibermall.
* ConnectX-7 (NDR/400G): Currently the mainstream choice for H100/Hopper deployments. It provides 400 Gb/s speeds and is the first to support PCIe Gen 5.0, which is critical for saturating modern GPU bandwidth. Lead times have stabilized to approximately 8–12 weeks PhilisunNvidia.
* ConnectX-6 (HDR/200G): The enterprise "workhorse." While it remains widely used for cloud networking and smaller AI clusters, it is increasingly viewed as a legacy option for high-end AI due to its 200 Gb/s and PCIe Gen 4.0 limitations. Standard configurations typically have short lead times of 2–4 weeks PhilisunReddit.
Sourcing & Product Summary
For sourcing, prices range from $250 for mid-range 25GbE cards to over $2,500 for high-end 400G adapters.
* ConnectX-7 400G OSFP: High-end NDR adapters are priced around $1,100–$1,550 per unit in the B2B market .
* ConnectX-6 Dx 100G QSFP56: A popular middle-ground for data centers, currently available for $740–$790 .
