7nm process 31 billion transistors Broadcom 25.6Tb/s bandwidth network chip shipped

In 2020, desktop vendors will start pushing 2.5Gbps or even 10Gbps NICs, ¬†entering ¬†10-megabyte network era, but it’s going to be weak compared to Broadcom’s latest network chips. Recently, Broadcom announced that its latest Tomahawk 4 network chip has been shipped at a rate of up to 25.6Tb/s, with a single chip supporting 64 sets of 400,000 megabit networks.

Broadcom is the world’s largest semiconductor design company, in addition to the familiar Bluetooth, WiFi chip, Broadcom on the high-performance network chip more powerful. The Tomahawk 4 chip is based on TSMC’s 7nm process, integrating 31 billion transistors, with four ARM cores and a frequency of 1.0GHz.

Compared to the previous Generation Ofahawk 3 chip, the Tomahawk 4’s network bandwidth doubled from 12.8Tb/s to 25.6Tb/s, and 512 PAM4 SerDes units were internally integrated, each supporting 50Gb/s of bandwidth, for a total of 25.6Tb/s, and a single chip that could support 64 sets of 400G or 256 100be-g network ports, which is 256 gigabit.

Thanks to the latest technology and architecture, the Tomahawk 4 chip will reduce customer operating costs by 75 percent, having previously been trialled in the networks of companies such as Ali, Google, Microsoft, Tencent and Uber, and is now officially delivered to customers.
