The Tofino chips were amazingly programmable, and before that, the Fulcrum chips were amazingly fast. Intel got ahold of both of them, and the magic was gone.
The latest Tofino 3 is... quite something to look at. Might actually take the cake for largest MCM and largest BGA package at over 10k pins. The POWER5 MCM is a similar size but has much fewer contacts.
