Broadcom’s AI chip revenue tripled, and none of it is a GPU

Broadcom’s AI semiconductor revenue reached $16.7 billion in the quarter to 2 August, against $5.2 billion a year earlier. It guided the next quarter to $21.7 billion. Total revenue was $29.6 billion, against $15.9 billion a year ago.

None of that line is a GPU. A custom accelerator is designed to one customer’s specification and fabricated for that customer alone, so it never appears in a catalogue and cannot be bought by anyone else. Broadcom also supplies the Ethernet switching silicon that wires those parts into racks, which is why the accelerator and the network sell together.

Nothing here asks a builder to change anything this week. The path shows up as one cloud’s API endpoint long before it shows up as a chip anybody can buy, and by then the choice has already been made for you.

What it changes The alternative to waiting for Nvidia allocation is increasingly a part your cloud designed itself, which you reach through that cloud’s API and not through CUDA.
