Don't quote me exactly but, They use a 64 bit IU bus which I believe is
divided up 32bits integer/ 32bits floating point instruction. So we are
talking 2 OPS per edge. How they get 120MOPS is something I don't want
(or care) to think about now (it's past my bed time).

)few simple TTL gates.

I didn't think (or get the impression) that it was GaAs.
