Broadcom is introducing a brand new networking chip known as Thor Extremely, designed to attach clusters of processors used usually in AI computing, based on Reuters. The chip can hyperlink a whole lot of hundreds of GPUs into clusters, to run and prepare giant AI fashions – and deepening Broadcom’s competitors with Nvidia.
The corporate introduced the chip alongside information of a serious deal to produce 10 gigawatts of customized silicon for OpenAI starting in 2026.
Broadcom shares fell about 4% after the announcement, however the firm stays assured that AI-related merchandise will maintain driving progress in its chip enterprise.
Connecting distributed AI programs
The Thor Extremely lets knowledge centre operators deploy extra chips than its earlier Tomahawk Extremely. It competes immediately with the networking interface merchandise of Nvidia, which dominate communications between GPUs in high-performance AI clusters.
“The community performs an especially necessary function in constructing these giant clusters,” stated Ram Velaga, Broadcom’s senior vp. “So I’m not shocked that anyone who’s within the GPU enterprise desires to ensure that they’re taking part within the networking.”
Networking efficiency is central to AI as a result of it determines how rapidly GPUs and accelerators can change knowledge. As AI purposes develop extra advanced, demand rises for sooner, lower-latency hyperlinks between chips.
Extending to edge and near-edge infrastructure
Whereas Thor Extremely is constructed for hyperscale knowledge centres, its design additionally helps rising edge and near-edge workloads, the corporate says, comparable to in factories, telecom networks, and regional knowledge centres.
The rising overlap between core cloud and edge programs is creating new alternatives for chipmakers. Networking now acts because the glue between the 2 ends of the computing spectrum.
Constructing on Broadcom’s latest strikes
Thor Extremely follows Broadcom’s launch of Tomahawk Extremely, a switch-level networking chip launched earlier in 2025, which centered on communication between GPUs inside a single system. Thor Extremely extends connectivity to knowledge centre campuses, letting operators to “scale out” as an alternative of simply “scale up.”
Broadcom additionally designs customized AI processors for main clients comparable to Google, and has labored on a number of generations of the Tensor Processing Unit (TPU) used to energy Google’s AI providers.
Contained in the design and testing course of
Broadcom’s engineers have doubled the bandwidth of Thor Extremely over the earlier era. Designing such processors includes coordination between chip and {hardware} groups on every little thing from energy and cooling wants by way of to packaging supplies. Broadcom doesn’t promote servers however shares reference system designs with clients to assist them construct their optimised networks.
“For each greenback we spend money on our silicon, there’s no less than $6 to $10 that our ecosystem companions make investments,” Velaga stated. “So, loads of our focus is on design, as if we’re nearly able to take [our designs] into manufacturing.”
Strengthening the AI knowledge spine
As extra enterprises deploy AI fashions that depend on distributed knowledge sources, Broadcom’s concentrate on networking might assist shut the hole between edge and cloud efficiency. The launch of Thor Extremely might place the corporate with an even bigger function in shaping how future AI programs talk.
