Tenstorrent Wormhole PCIe Cards (n150d/n150s/n300d/n300s) - official card comparison table

Vendor comparison table, all rows verified: Wormhole ASICs 1 (n150) / 2 (n300); Tensix cores 72 (n150, enabled) / 128 (n300, 64 per ASIC) out of 80 built per ASIC; SRAM 108 MB (n150) / 192 MB (n300); Memory 12 GB GDDR6 (n150) / 24 GB (n300); Memory Speed 12 GT/sec; Memory Bandwidth 288 GB/sec (n150) / 576 GB/sec (n300); TeraFLOPS (FP8) 262 (n150) / 466 (n300); TeraFLOPS (FP16) 74 (n150) / 131 (n300); TeraFLOPS (BLOCKFP8) 148 (n150) / 262 (n300); TBP 160W (n150) / 300W (n300); AI Clock 1 GHz; Connectivity 2x Warp 100 Bridge + 2x QSFP-DD 200G active on ALL four SKUs; Internal Chip-to-Chip N/A (n150) / 200G (n300); System Interface PCI Express 4.0 x16. IMPORTANT: the TFLOPS table has only FP8, FP16 and BLOCKFP8 rows. There is NO BFLOAT16 throughput row - BFLOAT16 appears only in the separate precision-support list. So a BF16 = 74 TFLOPS value is an inference, not a vendor figure. Process node is NOT published on this page.
