SiFive Adopts Nvidia NVLink Fusion Support
SiFive announced that its RISC-V CPU cores and SoC reference designs will support Nvidia's NVLink Fusion interconnect, enabling customers to pair SiFive CPUs with Nvidia GPUs and CPUs. NVLink Fusion offers up to 3.6 TB/s chip-to-chip bandwidth and lets racks of CPUs and GPUs appear as unified accelerators; SiFive says the integration targets data-center AI infrastructure. The move adds momentum to NVLink and pressures rival UALink.
Key Points
- 1Adds NVLink Fusion support to SiFive's RISC-V cores and SoC reference designs.
- 2Enables up to 3.6 TB/s chip-to-chip bandwidth, unifying racks into single accelerator fabrics.
- 3Pressures open-standard UALink adoption; practitioners should reassess interconnect choices for AI datacenter designs.
Scoring Rationale
Official company announcement reflecting broader NVLink ecosystem momentum, but limited novelty since many major vendors already adopted NVLink Fusion.
