“Networking should do more than just move data quickly – it should unlock the full potential of every compute cycle,” said Lisa Spelman, CEO of Cornelis. “That’s the performance we are offering customers with the CN5000 – a new breed of network-led application acceleration for AI and HPC applications where our scale-out network becomes a force-multiplier for performance at any scale.”
The World’s Highest-Performance Scale-Out Network for AI & HPC
CN5000 enables AI and HPC applications to achieve faster and more predictable job completion times, and greater computational efficiency by minimizing congestion events and maintaining highest throughput under load. For HPC workloads, CN5000 outperforms InfiniBand NDR with 2X higher message rates1, 35% lower latency1 and up to 30% faster simulation times2 driven by its advanced, congestion-free architecture. For AI applications, CN5000 delivers 6X faster collective communication3 compared to RoCE, driven by Omni-Path’s lossless architecture.
- AI at Scale: CN5000 delivers near-linear scaling of training performance for large language models and unlocks advanced inference with extended reasoning enabling higher-quality outputs and tackling previously intractable problems.
- Faster, More Predictable HPC: CN5000 delivers up to 30% faster execution for compute intensive HPC workloads like computational fluid dynamics (CFD), climate modeling, and seismic simulations with higher sustained throughput under real-world conditions compared to InfiniBand NDR.
- Universal Interoperability: CN5000 seamlessly interoperates with GPUs, CPUs, and accelerators, from AMD, Intel, NVIDIA, and more. Fully supports OpenFabrics software stacks for truly vendor-neutral deployments.

Strategic Innovation Roadmap
CN5000 is the first step in Cornelis’ long-term vision to revolutionize performance in scale out computing. The upcoming CN6000 (800G) will unify Omni-Path and RoCE-enabled Ethernet for double the bandwidth and seamless cross-paradigm integration. CN7000 (1.6T) is a revolutionary platform integrating Ultra Ethernet Consortium standards with Cornelis’ proven Omni-Path architecture, establishing a new performance frontier for the most demanding AI and HPC environments.
Availability
CN5000, Cornelis’ breakthrough AI and HPC scale-out networking solution, begins shipping to customers this month and will be broadly available starting Q3 2025 from all major OEMs.
