Some info from the Nature paper.<p>AlphaGo played Fan Hui using 1202 CPUs and 176 GPUs.<p>It&#x27;s strenght was assessed to be 3140 ELO on the scale used by www.goratings.org&#x2F; (BTW, this is different from the European ELO system)<p>That would put it at #279 in the world. Fan Hui is number 633 at 2916. AlphaGo&#x27;s next opponent will be Lee Sedol, #5 at 3515.<p>The single computer version of AlphaGo is estimated to be 2890 ELO, which would be #679 in the world. It&#x27;s is closer to what we might be playing against on our laptops and phones but still 48 CPUs and 8 GPUs.
