Broadcom Tomahawk 5
51.2 Tb/s Ethernet switch ASIC; the merchant-silicon answer to InfiniBand in AI fabrics.
Why this part
Merchant silicon, which is the whole argument. Broadcom does not sell switches; it sells the chip inside anyone's switch, so a hyperscaler can buy the ASIC, design its own box and run its own software without a network vendor in the middle. That is why RoCE Ethernet is a credible challenger to InfiniBand at the largest operators and nowhere else: the strategy requires you to be big enough to build your own hardware. Meta's RoCE cluster is the published example.
