The AI boom made GPUs famous. The dull chips that wire thousands of those GPUs together are quietly becoming just as valuable.
Xsight Labs, an Israeli chipmaker, has raised more than $300 million at a $2.8 billion valuation, it said on Thursday. Fidelity led the round. That is more than five times what the company was worth in 2021, a jump it made in a single year.
Xsight builds the plumbing of the AI data centre. Its two chips, the E1 processor and the X2 switch, shuttle data between servers, memory and networks. As models grow, moving that data has become one of the industry’s tightest bottlenecks, and the wiring between GPUs is now a prize of its own.
Taking on Nvidia’s other monopoly
Nvidia does not just sell the GPUs. It also dominates the networking layer, which it bought its way into with Mellanox. Xsight’s pitch is the opposite...
