Straight out of the box, the new machine plays at the same level as the best conventional chess engines, many of which have been fine-tuned over many years. On a human level, it is equivalent to FIDE International Master status, placing it within the top 2.2 percent of tournament chess players. But even with this disadvantage, it is competitive. “Giraffe is able to play at the level of an FIDE International Master on a modern mainstream PC,” says Lai. By comparison, the top engines play at super-Grandmaster level.

That's a pretty hard contradiction right there. The latter quote is probably the correct one. Modern chess engines beat any human player these days, even running on relatively modest hardware. That's assuming full length games. At blitz games computers are much better still, compared to humans, because humans are much more error prone.

So if this neural net is playing at master level it's still much, much weaker than the best computers. From master to grandmaster is a big leap, from grandmaster to world top is another big leap, and the best computers are above even that.

Still interesting of course.
