Did you ever think about that the BETA board not use a NV30?
I remeber that the BETA board from 3dfx for the VSA-100 (Voodoo 5 chips) was a monster of several Voodoo 2 (or 3) chips.
So maybe the BETA board use ASICS and maybe several NV25 chips(?)
It could be thrught, that there are BETA boards available and also the NV30 hasen't taped out. Nobody say that the silicon on the BETA boards is the same design than the NV30. So maybe the BETA boards are multichip (?) and the NV30 is only one (?)
So the CEO is right, NV30 not taped out and all the other who saw (?) BETA board are right too. And even the performance could be estimated with such a board.
Just my 2 cents
