"In 2027, we believe each of them plans to deploy 1 million XPU clusters across a single fabric," Tan said of the three hyperscale customers.
In addition to AI chips, AI server clusters need powerful networking parts to train the most advanced models. Networking chips for AI accounted for 76% of Broadcom's $4.5 billion of networking sales in the fourth quarter.
Broadcom said that, in total, about 40% of its $30.1 billion in 2024 semiconductor sales were related to AI, and that AI revenue would increase 65% in the first quarter to $3.8 billion.
"The degree of success amongst the hyperscalers in their initiatives here is clearly an area up for debate," Cantor analyst C.J. Muse, who recommends buying Broadcom shares, wrote in a report on Dec. 18. "But any way you slice it, the focus here will continue to be a meaningful boon for those levered to custom silicon."
