NVIDIA NVLink-C2C

Extending NVLink to chip-level integration.

Ultra-Fast Chip Interconnect Technology for Custom Silicon Integration

NVIDIA NVLink™-C2C extends the industry-leading NVLink technology to a chip-to-chip interconnect. This enables the creation of a new class of integrated products with NVIDIA partners, built via chiplets, allowing NVIDIA GPUs or CPUs to have a high-bandwidth, coherent connection with custom silicon.

Products Using NVLink-C2C

NVIDIA GB300 NVL72

NVIDIA's GB300 NVL72 integrates 72 NVIDIA Blackwell Ultra GPUs and 36 NVIDIA Grace™ CPUs, offering a 50x increase in AI factory output with optimized inference capabilities.

NVIDIA GB200 NVL72

The NVIDIA GB200 Superchip combines two NVIDIA Blackwell GPUs and an NVIDIA Grace CPU connected over NVLink-C2C and can scale up to the GB200 NVL72, a massive 72-GPU system connected by NVIDIA NVLink.

NVIDIA Grace Hopper Superchip

The NVIDIA Grace Hopper™ Superchip combines the Grace and Hopper architectures using NVIDIA NVLink-C2C to deliver a CPU+GPU coherent memory model for accelerated AI and high-performance computing (HPC) applications.

NVIDIA Grace CPU Superchip

NVIDIA Grace CPU Superchip uses the NVLink-C2C technology to deliver 144 cores and 1 TB/s of memory bandwidth for cloud, enterprise, and high-performance computing.

NVIDIA DGX Spark

NVIDIA DGX Spark is a compact, personal AI supercomputer accelerated by the NVIDIA GB10 Grace Blackwell Superchip, delivering high-performance AI capabilities and support for models up to 200 billion parameters.

NVIDIA NVLink Fusion

NVIDIA NVLink™ Fusion delivers industry-leading AI scale-up and scale-out performance with NVIDIA technology plus semi-custom ASICs or CPUs, enabling hyperscalers to build an ASIC hybrid AI infrastructure with NVIDIA NVLink technology and rack-scale architecture.

NVLink-C2C Benefits

High Bandwidth

Supports high-bandwidth, coherent data transfers between processors and accelerators.

Low Latency

Supports atomics between processors and accelerators to perform fast synchronization and high-frequency updates to shared data.

Low-Power High Density

Uses advanced packaging to deliver 25x more energy efficiency and 90x more area-efficiency than PCIe Gen 5 PHY on NVIDIA chips.

Industry Standards

Supports Arm’s AMBA CHI (Coherent Hub Interface) or Compute Express Link (CXL) industry standard protocols for interoperability between devices.
