Steamroller is part of the 15h family, and has a module approach similar to Bulldozer and Piledriver. After which is where the similarities start to become fuzzy.
Steamroller peak IPC = Excavator peak IPC
Steamroller/Excavator peak IPC = 2.2x Bulldozer/Piledriver peak IPC.
Steamroller is 15h derived, bulldozer module derived, but it isn't architecturally derived from Bulldozer or Piledriver. Excavator is 15h derived, bulldozer module derived, and is architecturally Steamroller-derived.
What can differentiate Steamroller and Excavator is;
TSMC or GlobalFoundries
Instruction Set Extensions
