Tenstorrent Wormhole
Tenstorrent Wormhole is a scalable PCIe AI accelerator family for workstation and server workloads.
Wormhole provides n150 and n300 PCIe accelerator cards built with Tensix Cores. The cards support multichip meshes, multiple data formats, and Tenstorrent’s open-source TT-Forge and TT-Metalium SDKs.
Developers use Wormhole cards for AI inference, model development, and high-performance computing. Cards require a compatible PCIe 4.0 x16 system and EPS12V power; cables, bridges, workstations, and cloud access may cost extra.
