Broadcom Introduces Thor Ultra, the Industry's First 800G UEC-Compliant AI Ethernet NIC

Broadcom Inc. (NASDAQ:AVGO) is one of the best big tech stocks to invest in now. On October 14, Broadcom announced the introduction of Thor Ultra, the industry’s first 800G AI Ethernet Network Interface Card/NIC. Thor Ultra is capable of interconnecting hundreds of thousands of XPUs to manage trillion-parameter AI workloads and is a key addition to Broadcom’s Ethernet AI networking portfolio, which includes products like Tomahawk 6, Jericho 4, and Scale-Up Ethernet/SUE.

Thor Ultra is fully compliant with the Ultra Ethernet Consortium/UEC specification, an open standard designed to modernize RDMA for large AI clusters. By adopting this open specification, the NIC provides customers with the ability to scale AI workloads with high performance and efficiency while reducing dependency on proprietary, vertically integrated solutions.

The new NIC introduces a suite of UEC-compliant, advanced RDMA innovations to address the limitations of traditional RDMA. These innovations include Packet-Level multipathing for efficient load balancing, Out-of-Order packet delivery directly to XPU memory to maximize fabric utilization, Selective retransmission for efficient data transfer, and Programmable Receiver-based and Sender-based congestion control algorithms.

Broadcom Inc. (NASDAQ:AVGO) designs, develops, and supplies various semiconductor devices and infrastructure software solutions worldwide. The company operates in two segments: Semiconductor Solutions and Infrastructure Software.
