Overview
NVIDIA's proprietary high-speed GPU-to-GPU interconnect that lets multiple GPUs act as a single coherent compute fabric; the fifth-generation version shipped with Blackwell at 1.8TB/s per GPU, and NVLink 6 has since entered full production with the Rubin platform, delivering 3.6TB/s per GPU and 260TB/s across a Vera Rubin NVL72 rack.
Strategic Connections
- Blackwell: Blackwell GPUs depend on fifth-generation NVLink to operate as a coherent multi-GPU fabric for large-scale model training.
- NVIDIA: NVLink is NVIDIA's proprietary interconnect technology, developed and controlled exclusively by NVIDIA.
- Blackwell: Fifth-generation NVLink enables Blackwell GPUs to operate as a single coherent fabric across up to 72-576 GPUs for large-scale model training.
- Marvell Technology: NVLink Fusion, unveiled in 2026, opens NVIDIA's interconnect to third-party silicon for the first time; Marvell is the first partner, building custom XPUs and scale-up networking compatible with NVLink Fusion as part of a deal that included a $2 billion NVIDIA equity investment in Marvell.
Strategic Risks
- NVLink coherence is proprietary to NVIDIA hardware, creating lock-in that prevents mixed-vendor GPU clusters
- Scaling beyond a single NVLink domain requires falling back to slower InfiniBand or Ethernet interconnects
Future Outlook
- NVLink 6 and the Rubin platform now in full production, targeting up to 10x lower inference token cost and 4x fewer GPUs needed to train MoE models versus Blackwell
- Growing importance as mixture-of-experts model architectures increase inter-GPU communication demands
