Go up one level in this thread


Deep Blue was a *Multi-Million* dollar machine. Significantly more than
"$100,000".

It has a *ton* more computing power than you seem to think. And this power is
dispersed in ways vastly different from any single-processor architecture of
today. It's a completely different architecture than any single-processor PC. It
is virtually impossible to make statements like you have made; it's kind of like
saying 'If a Chevy Malibu had the engines of the Space Shuttle, it would go
faster'. This is not true for a variety of reasons. The two are simply
incomparible on a superficial level, as is Deep Blue vs. today's typical micro
program.
