This is more the *average* speed of the system. I have seen figures of up to 1
billion nodes per second, in favourable (for speed) positions.

This doesn't say, of course, what the search speed would have been in your test
position. Could have been 150M nodes/s, could have been 950M nodes/s...


The comparison of speed is also somewhat flawed by the fact that Deep Blue was
explicitly designed to be fast (as in nodes per second), which most of the other
programs are not.

This is somewhat like comparing Intel and AMD, where the P4 *is* designed to
have a high clock rate, even if it means doing less work per clock.
