Shark is network based deep search meta engine. It is based on unique idea by which it reaches to depth of 25+ easily with the help of only 6 CPUs in less than a minute. Currently a dual core CPU takes more than an hour to reach to this depth.

Not that it matters all that much. Hardware is important, but in a game anything can happen. I remember Rybka on my quad beat Spark 1.30 running on 16 cores.
