Microcode doesn't control everything the CPU hardware does

  I'm aware, that's why I asked. Do you know? Do you have a reference? (And I'll laugh pretty hard if it's confirmed that these super-complex branch buffer adjustments are possible, but simple prefetch filters are just not possible on current Intel hardware.)

    No I don't have any reference. But I don't find it soon hard to believe that complex things have knobs while simple things don't.
