Tomahawk 6 is First to 102.4T Through relentless execution, Broadcom has been first to market generation after generation in data-center switching. The company just announced sampling of Tomahawk 6 (TH6), its 102.4T Ethernet switch ASIC. This generation actually consists of two switch chips, TH6-200G with 512x200G SerDes, and TH6-100G with 1,024x100G SerDes, both of which are sampling now. A version with fully co-packaged optics, TH6-Davisson, will follow on a to-be-announced schedule.  Whereas Tomahawk 5 (TH5) is a monolithic 5nm chip, TH6 comprises a core die and separate chiplets for the two SerDes options, all of which use 3nm technology.

Fewer tiers mean lower latency, simpler load balancing and congestion control, and fewer optics. The new chip is first to handle 1.6T Ethernet ports, but it also handles up to 512x200GbE ports for maximum radix. Beyond sheer port density, TH...
