Critical Dependencies
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.

Market Intelligence
UnverifiedCredibly-reported claims — analyst notes, sourcing citing “people familiar with the matter,” deals where the companies involved declined to comment — that haven't been officially confirmed. Kept structurally separate from the sourced evidence above; treat as a lead worth researching further, not an established fact.
Opening NVLink to third-party silicon via NVLink Fusion (Marvell, Lightmatter) while NVLink itself remains the proprietary lock-in mechanism is a calculated tension -- NVIDIA appears to be trading a degree of exclusivity for deeper ecosystem entrenchment, letting custom XPUs plug into NVIDIA's fabric rather than customers building fully independent interconnect stacks
30% confidenceThis is a defensive-offensive move: it reduces the incentive for hyperscalers to build NVLink-independent scale-up fabrics (which would erode NVIDIA's lock-in over time), while still keeping NVIDIA as the switching and coherence layer every participant depends on.
This is InsightNodes' own interpretive read on the strategic logic behind NVLink Fusion's third-party openness; NVIDIA's own announcements frame Fusion as ecosystem expansion without addressing the lock-in tradeoff.

NVLink's Timeline
A sourced, dated history of NVLink's key moments — founding to present.
Jan 2026 · NVLink 6 enters production with Rubin
NVLink 6 entered full production with NVIDIA's Rubin platform, delivering 3.6TB/s per GPU and 260TB/s across a Vera Rubin NVL72 rack.
Jun 2026 · Lightmatter joins NVLink Fusion with photonic interconnects
Photonics startup Lightmatter joined the NVLink Fusion ecosystem, following Marvell as an early third-party partner, to deliver co-packaged optics (CPO) and near-packaged optics (NPO) products compatible with NVIDIA's optical and SerDes technologies for scale-up AI infrastructure.
Aug 2026 · NVLink Fusion expands with NVHBM; Amazon Annapurna Labs first partner
NVIDIA expanded NVLink Fusion with NVHBM, a high-bandwidth-memory approach for custom XPUs that can free up to 25% of XPU die area for compute, cut HBM power by up to 15%, and boost effective bandwidth by up to 30%; Amazon's Annapurna Labs is the first partner working with NVIDIA on the technology, following earlier 2026 NVLink Fusion ecosystem additions including Marvell (backed by a $2 billion NVIDIA investment) and Ayar Labs.

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.
