> [...] it took until 2009 for something (really) interesting to happen, a program called ‘pocket Fritz’ achieved parity with Deep Blue in terms of strength while running on a mobile phone and evaluating only a small fraction of the number of positions evaluated by Deep Blue. In terms of power efficiency that’s an absolutely enormous leap and it brought - in my view at least - for the first time the game on a level footing. Humans and Chess computers were now competing at approximately the same level of energy consumption. -- https://jacquesmattheij.com/another-way-of-looking-at-lee-sedol-vs-alphago/ https://jacquesmattheij.com/another-way-of-looking-at-lee-se... > In 2009, a chess engine running on slower hardware, a 528 MHz HTC Touch HD mobile phone, reached the grandmaster level. The mobile phone won a category 6 tournament with a performance rating of 2898. The chess engine Hiarcs 13 runs inside Pocket Fritz 4 on the mobile phone HTC Touch HD. Pocket Fritz 4 won the Copa Mercosur tournament in Buenos Aires, Argentina with 9 wins and 1 draw on 4–14 August 2009.[33] Pocket Fritz 4 searches fewer than 20,000 positions per second.[34] This is in contrast to supercomputers such as Deep Blue that searched 200 million positions per second. Pocket Fritz 4 achieves a higher performance level than Deep Blue. -- https://en.wikipedia.org/wiki/Human%E2%80%93computer_chess_matches#Pocket_Fritz_4_.282009.29 https://en.wikipedia.org/wiki/Human%E2%80%93computer_chess_m...
