Yes massive better.

Hsu has written many articles.

here is a summary of what Chrilly has said in way more words (voice)
when he was staying here for a few days:

  Hsu was one of the first to make a move generator. He didn't write it in
  verilog but in the direct logics of the chip. Very incompatible method.
  Custom made by hand. It is incredible that he managed to write at such a
  low level anyway. However, a bad result from writing at such a low level is
  that the scale and size of the logics is so big that he must have
  lost oversight. I write in a more compatible language called Verilog and
  that is not comparable to C but way closer than the very 'assembly' way
  in which Hsu has written his logics at. It means in short that Brutus
  move generator therefore is very small. Note that i MUST make it small
  because i am commercial and more gates is more money to pay for. In the
  first chip i had just 50000 gates in total and that is very very little to
  get a chessprogram working in.
  From my viewpoint all the things i have seen so far is utmost beginners
  level. This is logical, They are hardware designers, not chessprogrammers.
  I focus upon the chess programming technical result. They had so much other
  problems to deal with from hardware viewpoint that we can not even compare
  it in that sense.

Best regards,
Vincent
