Broadcom Releases 7nm Tomahawk 4 Network Chip: A Single Chip Can Carry 64 400,000 Mbit

- Jan 25, 2021-

Semiconductor giant Broadcom announced that it has built a new Tomahawk 4 network chip based on TSMC’s 7nm process, which can carry 64-port 400Gbps (400 Gigabit) or 256-port 100GbE (100,000 Gigabit) switching and routing services on a single chip.

The chip integrates up to 31 billion transistors, the power consumption is 75% lower than the same utility solution, and the throughput is twice that of competing products.


According to Broadcom, this network chip uses a 4-core design, ARM solution, and clocked at 1GHz.

Broadcom said that many of its major customers are already trialling devices equipped with Tomahawk 4 chips, including Alibaba Cloud, Google Cloud, Microsoft, Tencent and Uber.

Yiqun Cai, vice president of Alibaba Cloud Intelligence network, said that the company has worked closely with Broadcom on Tomahawk 4 products, and the company is accelerating its ability to adopt 100/200/400 GbE Ethernet solutions.
