Computing Interconnects
NVLink
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.

NVLink ↔ NVIDIA
Jun 2026
NVIDIA confirmed Vera Rubin entered full production with NVLink 6, delivering 3.6TB/s of bandwidth per GPU and 260TB/s across a Vera Rubin NVL72 rack — double the bandwidth of fifth-generation NVLink shipped with Blackwell.
Now
NVLink is NVIDIA's proprietary interconnect technology, developed and controlled exclusively by NVIDIA.
NVLink ↔ Blackwell
Mar 2024
Fifth-generation NVLink shipped with Blackwell delivering 1.8TB/s of bidirectional bandwidth per GPU, enabling coherent communication among up to 576 GPUs for large language and mixture-of-experts models.
Now
Fifth-generation NVLink enables Blackwell GPUs to operate as a single coherent fabric across up to 72-576 GPUs for large-scale model training.
NVLink ↔ Blackwell
Mar 2024
Blackwell's GB200/GB300 NVL72 rack-scale systems relied on fifth-generation NVLink's 1.8TB/s per-GPU bandwidth to connect up to 72 GPUs as a single coherent fabric.
Now
Blackwell GPUs depend on fifth-generation NVLink to operate as a coherent multi-GPU fabric for large-scale model training.
NVLink ↔ Marvell Technology
Mar 2026
NVIDIA and Marvell announced a strategic partnership connecting Marvell to NVIDIA's AI factory ecosystem through NVLink Fusion, with NVIDIA investing $2 billion in Marvell and the companies also collaborating on silicon photonics.
Now
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.
