Why Did Arm Start Selling Its Own Chips?

Rene Haas says Arm started selling a physical chip because product cycles were not slowing down, manufacturing was taking longer, and Meta could not buy the general-purpose CPU it wanted from anyone else. Arm began by licensing pieces, including CPU IP, GPU IP, and system IP. A few years earlier it moved to compute subsystems, a blueprint for how to stitch those pieces together. Demand for the subsystems was strong because they cut time to market and cost. A physical product was the next step. Some customers already have everything they need to build an Arm-based chip. Many other companies want an Arm-based product, and not every Arm customer serves those markets. Meta was the first example. It wanted a general-purpose agentic CPU, nobody else would supply one, and it asked Arm to build the project with them.

Haas says Arm asked its customers before the move, because CPU IP is only as useful as the chip and software ecosystem around it. Nvidia, Amazon, Microsoft, and Google, which build Arm-based server chips, were in favor. More software in the wild, whether proprietary or open source, helps the broader ecosystem and those customers too.
