Are you sure a single processor being 5 times faster than a good PC
program would play better? The current selection sheme of PC programs
are quite complex (I use much selection in Chess Tiger), and I'm not
sure the logic of the chip is able to do something like that.

Take out the selection algorithms (or just make it a little less
efficient) in a deep computation (level 12-13 for example), and you will
have to wait 100 times more to get the same result.

So maybe the power of DB comes from the huge number of processors more
than from the fast NPS.

BTW, I've heard DB is brute force (no selection). Has anybody
information about that?
