March 4, 2000 release = 10.5 million transistors November 11, 2006 release = 235 million transistors. Difference of 2,444 days, or 80.2895 months, between each release. Hypothesis: transistor count doubles every 18 months. 80.2895/18=4.460. So the hypothesized transistor count of a PS3, assuming a doubling of transistors every 18 months, should equal 231.09 million: 10.5*2^4.460 = 231.09. This is pretty close to the actual number of 235 million.
