But is that good or not ? 4x 1r1w regifile will be ~30% faster than a true 3r2w.

i don't know, but i'd rather like to have 8 or 16 banks instead of only 4
(less chances of collisions).

don't forget that the "2w" part comes from both "2r2w" instructions
and couples of instructions with different latencies that end at the same time.
