Retym Secures $75 Million for AI Networking Chips

Retym has raised $75 million this year as part of a $180 million total funding effort to develop networking chips for artificial intelligence computing in data centers, reports Reuters. The company focuses on digital signal processing (DSP) chips that facilitate rapid data transfer between large data centers, a critical need as AI applications grow.

Retym's DSP chips aim to solve connectivity bottlenecks in data centers, a challenge that arises when numerous chips must work together on AI tasks. The company's first chip is designed to move data over distances ranging from 10 to 120 kilometers, optimized for 30 to 40 kilometers. This chip uses a modulation technique to ensure data integrity during transfer.

The Series D funding round was led by Spark Capital, and Retym plans to bring its first product to market this year. The chips are being developed using Taiwan Semiconductor Manufacturing Co.'s five-nanometer process, with engineers currently testing and validating samples.
