Tenstorrent Wormhole n150s — 72-Core RISC-V AI Accelerator PCIe Card

Specifications

Overview

The Tenstorrent Wormhole n150s (order code TC-02001) is a single-ASIC PCIe accelerator card built around 72 Tensix cores — RISC-V based compute tiles with their own vector and matrix engines. Tenstorrent publishes the whole Wormhole PCIe card family openly, and the n150s is the single-chip, actively-cooled member.

The design trades on memory density close to compute: 108 MB of distributed on-chip SRAM sits next to the Tensix cores, backed by 12 GB of GDDR6 at 288 GB/s and a 160 W envelope. For inference workloads the open-source TT-Metalium / TT-NN / TT-Forge stack lets teams write and tune their own kernels rather than depend on a closed compiler.

QS Compute supplies Wormhole cards alongside the Blackwell-generation Tenstorrent parts and the mainstream NVIDIA and AMD accelerators, so customers can build heterogeneous inference nodes.

Key Benefits

72 Tensix RISC-V cores with 108 MB SRAM keep activations on-chip for LLM and vision inference. Open-source TT-Metal stack avoids vendor lock-in and lets teams tune kernels. 160 W / single slot-class power enables dense edge inference nodes. 12 GB GDDR6 at 288 GB/s holds larger models and batched weights.

Applications

Edge and on-premises LLM inference; vision and transformer inference nodes; research and university AI clusters; heterogeneous inference servers needing low power per token; and model-development workstations using the open TT-Metal stack.
