DreamBig Announces world leading 800G AI-SuperNIC chip (Mercury) with Fully HW Offloaded RoCE v2 + UEC RDMA Engine

Mercury delivers 800Gbps bandwidth connectivity for any AI chipset with industry leading throughput of 800Mpps while minimizing power consumption, latency, and area. It features a hardened RDMA engine with programmable congestion control for RoCE v2 and UEC standards, making it an ideal solution for AI and HPC applications. When integrated as a chiplet compatible component with previously announced DreamBig Mars Chiplet Platform, the solution can scale to 12.8Tbps RDMA throughput.

San Jose, Calif., January. 6, 2025 — DreamBig Semiconductor, Inc. today proudly unveils Mercury AI-SuperNIC, that enables scaling-out of next generation AI Platforms  by seamlessly connecting GPUs with unparalleled efficiency.  

DreamBig Mercury chip features a hardware accelerated RDMA engine that supports existing RoCE (RDMA over Converged Ethernet) v2 and new UEC (Ultra Ethernet Consortium) standards, delivering best-in-class bandwidth (800Gbps) and throughput (800Mpps) with lowest power, ultra low latency, and smallest area.

Mercury is designed with fully programmable Congestion Control to adapt to any data center and provides the following critical functions for AI applications

• Multi-pathing and packet spraying
• Out-of-order packet placement with in-order message delivery
• Programmable congestion control for RoCE v2 and UEC algorithms
• Advanced packet trimming and telemetry congestion notifications
• Support for selective retransmission

Mercury provides UEC-compliant software drivers enabling GPU-to-GPU communication with exceptional throughput and minimal latency.

“This year marks the 25^th anniversary that the team we have assembled at DreamBig has been developing RDMA together, from Infiniband to iWARP to RoCE, and now UEC. All that experience has gone into re-architecting RDMA from the ground up for the AI era,” said Steve Majors, SVP of Engineering at DreamBig Semiconductor. “With the efficiency of full HW RDMA offload, innovative layering to adapt to evolving Ethernet transport modes and congestion control methods, and unparalleld performance scaling from 800Gbps to 12.8Tbps, DreamBig is setting the bar for the next several generations of AI networking.”

As a groundbreaking monolithic chip, Mercury redefines 800Gbps discrete networking for TPUs/GPUs, combining unmatched performance, power efficiency, and cost-effectiveness to meet the demands of next-generation AI platforms. As a chiplet compatible component, Mercury provides unparalleled scaling of upto 12.8Tbps integrated networking for AI SuperChips.
