D-Matrix targets Nvidia MGX rack integration for Raptor XPU by Q4 2027

AI inference chip startup d-Matrix plans to integrate its Raptor XPU into Nvidia's MGX rack architecture by Q4 2027, with a first Raptor tape-out expected before the end of 2026. D-Matrix says Raptor, which debuted at Hot Chips 2026 in August, combines a TSMC 4nm logic die with 3D-stacked DRAM to deliver over 100 TB/s of memory bandwidth and 32 GB of capacity per card, claiming roughly 4.7 times higher throughput per card than HBM-based alternatives for generative inference. The Santa Clara company has raised between $450 million and $500 million total, including a $275 million Series C that valued it at about $2 billion, and the Raptor integration involves connectivity chipmaker Astera Labs.

The Santa Clara-based firm expects its first Raptor tape-out to land before the close of 2026, with full rack-scale deployment targeting Q4 2027. D-Matrix is integrating Raptor with Nvidia’s NVLink Fusion interconnect, which means up to 144 Raptor XPUs could operate inside a single NVLink fabric by the time 2027 wraps up. What Raptor is actually built to do Raptor debuted publicly at Hot Chips 2026 in August, and the technical specs are worth paying attention to. The platform combines a TSMC 4nm logic die with 3D-stacked DRAM, targeting over 100 TB/s of memory bandwidth with 32 GB of capacity per card. D-Matrix claims Raptor delivers approximately 4.7 times higher throughput per card compared to HBM-based alternatives for generative inference tasks. The Corsair foundation and the funding behind it Raptor is d-Matrix’s next act, but the company is not a pre-revenue concept. Its current platform, Corsair, is already in production and uses digital in-memory compute built on SRAM. The company has raised between $450 million and $500 million in total funding, including a $275 million Series C round that valued the company at roughly $2 billion. Partners in the broader ecosystem include Alchip and Andes, and the Raptor integration specifically involves Astera Labs, a connectivity chipmaker that sits inside Nvidia’s technology ecosystem.
