Grayskull™ Tensix Processor
The Grayskull™ e75 and e150 Tensix Processor add-in boards are built using the Tenstorrent Grayskull™ Tensix Processor:
Tensix Core Count: 120
SRAM: 120MB (1MB per Tensix Core)
Memory: 8GB LPDDR4, 256-bit memory bus
e75/e150 Comparison Table
NOTE: The e150 add-in card comes 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 Active Cooling Kit is required. 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.
