d-Matrix Corsair

The d-Matrix Corsair is a full-height full-length PCIe inference accelerator built around a two-tier memory system rather than HBM. Each card carries 2 GB of on-die performance memory running at 150 TB/s, backed by up to 256 GB of off-die capacity memory, and delivers 2,400 TFLOPS of MXINT8 and 9,600 TFLOPS of MXINT4. d-Matrix labels those figures "dense" itself, so the basis is stated rather than inferred, and it publishes no sparse figure. Cards are joined by a 512 GB/s card-to-card DMX Bridge. Note that d-Matrix publishes card figures only for what it calls the "Corsair Dual Card", a bridged pair; the per-card values here are that pair halved, which is corroborated nine separate ways by d-Matrix's own eight-card server and sixty-four-card rack figures, every one of which divides cleanly onto a single card. The 150 TB/s belongs to the on-die SRAM and is deliberately not recorded as memory bandwidth, which on this site means DRAM bandwidth. d-Matrix publishes no TDP, no process node and no PCIe generation for this card, so those fields are left blank rather than estimated.
