AI chip startup d-Matrix is pushing into rack scale with the introduction of its JetStream I/O cards, which are designed to allow larger models to be distributed across multiple servers or even racks while minimizing performance bottlenecks.
At face value, JetStream presents itself as a fairly standard PCIe 5.0 NIC. It supports two ports at 200 Gb/s or a single port at 400 Gb/s and operates over standard Ethernet.
