What happened
Nicholas Carlini ported Stockfish to a 200 MHz Intel Pentium Pro with 64 MB of RAM — hardware from the same era as Deep Blue — and estimates it plays at Elo 3300 ± 87 at classical time controls, well above Kasparov's roughly 2800 in 1996. Deep Blue cost several million dollars in R&D and relied on 480 custom VLSI chess co-processors plus 30 P2SC processors at ~120 MHz to analyze 200 million positions per second, ranking 259th among supercomputers of the time. The Pentium machine is online via a Realtek RTL8139C Ethernet card and playable through a Lichess link, with its VGA text screen refreshing every second.
Why it matters
Thirty years of algorithmic work bought roughly 500 Elo on hardware of the same class — the engine's strength came from move selection and evaluation, not from a bigger machine. Before you budget for more GPUs or a faster cluster, check whether the bottleneck is really compute or the method; this is a concrete, playable counterexample to 'just scale it'. The ±87 Elo error bar also means the exact number is an estimate, so treat it as a directional result, not a measurement.
Discussion angle
Ask the room where a smarter algorithm has replaced a bigger machine in their own stack in the last few years — and how Carlini's estimated Elo was actually derived, since a ±87 error bar on a self-reported engine rating is the weakest link in an otherwise very concrete claim.
