Tomahawk 6: The industry’s first 100-terabit switch chip

Part 2: Data Centre Switching

Peter Del Vecchio, product manager for the Tomahawk switch family at Broadcom, outlines the role of the company’s latest Tomahawk 6 Ethernet switch chip in AI data centres.

Broadcom is now shipping samples of its Tomahawk 6, the industry’s first 102.4-terabit-per-second (Tbps) Ethernet switch chip.

The chip highlights AI's impact on Ethernet networking switch chip design since Broadcom launched its current leading device, the 51.2-terabit Tomahawk 5.

The Tomahawk 6 is more evolutionary, rather than a complete change, notes Del Vecchio.

The design doubles bandwidth and includes enhanced networking features to support AI scale-up and scale-out networks.

Trident 4 boosts enterprise switch capacity to 12.8 terabit

  • Broadcom’s Trident 4 switch chip has a capacity of 12.8 terabits, 4x the capacity of its Trident 3.
  • The chip reduces fourfold the cost of a 128x100-gigabit switch.  
  • The Trident 4 adds compiler programmability  
  • This is the company’s first switch chip in 7nm CMOS. 

Broadcom has unveiled the Trident 4, its latest family of switch chips for the enterprise. 

The largest-capacity Trident 4 family member, the X11 chip, has a switching capacity of 12.8 terabits. This is a fourfold increase in capacity compared to Broadcom’s current high-end enterprise chip, the Trident 3, announced in June 2017.  

The Trident 4 will also reduce the cost of a 128x100-gigabit switch by a factor of four. The current cost of a 12.8-terabit switch, a multi-chassis solution, is $245,000 not including the pluggable optics, says Broadcom, citing market research firm, The Dell’Oro Group.

“The announcement is significant both in updating the Trident line for enterprise and in adding compiler programmability thereby limiting the openings for competitors such as Barefoot - soon Intel - Innovium, and Marvell,” says Bob Wheeler, vice president of The Linley Group and principal analyst for networking.
