Tenstorrent Wormhole

Tenstorrent Wormhole is a scalable PCIe AI accelerator family for workstation and server workloads.

Tenstorrent Wormhole

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.

Features

  • n150 and n300 PCIe accelerator cards
  • Multichip mesh networking for workstations and servers
  • Tensix Cores with compute, local cache, NoC, and RISC-V cores
  • Supports broad data precision formats
  • Open-source TT-Forge SDK for high-level development
  • Open-source TT-Metalium SDK for low-level development
  • PCI Express 4.0 x16 system interface
  • Active or passive cooling options

Use cases

  • Develop and test AI inference workloads
  • Run models on single or multiple accelerator cards
  • Build scalable workstation and server AI systems
  • Port high-performance computing libraries
  • Experiment with low-level AI kernels
  • Access Wormhole hardware through cloud instances
