  The Apache #’s pretty much give the game away: An Itanium clocked 50% higher was losing to a 2yo Alpha by about 20% on throughput at peak.

  VLIW made sense when Intel wanted to win the FP-heavy workstation market. But while it was in development, integer-heavy web workloads became dominant and that was basically the ballgame.

  Amusingly similar to the much more recent slide decks about the x86 port, e.g. https://vmssoftware.com/docs/State_of_Port_20171006.pdf
