A (not very sensible) alternative: FMADD + FADD

As an alternative to having two FMADD units at c. 1.3 GHz, one could imagine having one FMADD unit and one FADD unit at c. 1.74 GHz. This is presumably still too high a clock for the design target (though less implausible than 2.6 GHz), but it seems not entirely crazy within wild mass guessing.
