Got me curious since I never looked at DB specs:

` It was a massively parallel, RS/6000 SP Thin P2SC-based system with 30 nodes, with each node containing a 120 MHz P2SC microprocessor, enhanced with 480 special purpose VLSI chess chips.`

I misread at first thinking it was grossly 30GHz summed but it's only 3.6GHz (I know, gross maths). So yeah the comparison is apt.. a recent SoC can outperform this old behemoth.

Not only is your smartphone hardware probably more powerful than DeepBlue, but chess engines are a lot more efficient nowadays (even without AlphaZero / reinforcement learning). The engines are getting better on the same hardware every year. On identical hardware, Stockfish (the top non-RL engine) is 800 Elo better today than it was 10 years ago.[1] A difference of 400 Elo corresponds to a 90% win rate for the better player (where a draw counts as half a win).
