Specifications/Requirements
Wormhole™ Tensix Processor
The Wormhole™ n150d, n150s, n300d, and n300s Tensix Processor add-in boards are built using the Tenstorrent Wormhole™ Tensix Processor:
Tensix Core Count: 80
SRAM: 120MB (1.5MB per Tensix Core)
Memory: 12GB GDDR6, 192-bit memory bus
Card Comparison Table
NOTE: The n150s and n300s add-in cards come with a heatsink for passive cooling in systems which can provide sufficient forced airflow to the card. If your system does not (for example, a desktop workstation), installing the bundled Active Cooling Kit is required; we strongly recommend desktop workstations use the n150d and n300d add-in cards which are designed for desktop deployment. If the card isn’t sufficiently cooled, performance will be substantially reduced to stay in a safe operating temperature range and you risk damage to the card.

Connectivity
Wormhole™ cards include two different methods for interconnecting cards. (n150s/n300s pictured; n150d and n300d will have the same ports and bridges.)
The Warp 100 notches are for attaching internal Warp 100 bridges between Wormhole™ cards.
The two QSFP-DD ports are active and support 400GbE connectivity between cards and/or Wormhole™-based systems/servers.
