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.
