I guess this is not macbook pro specific, so mods can move this thread if they want. Today, i got to thinking about CPU performance the last 5-20 years, and it really got me thinking. In 1993 the clock freq on a normal cpu at 60mhz. In 2003, 10 years later, we had clock freq at 3.0Ghz. Thats a 50 times increase in 10 years. Where are we now 9 years later? We are still around the 3.0ghz mark. Know, of course in this years we have gotten more threads/cores and improved cache, integrated graphics and other goodies. However, many many programs still don't take advantage of all this cores. From a gaming point of view, there are very few games that actually take advantages of 4 cores. Example 1: (taken from anandtech) Thats 21% increase. Example 2: (also from anandtech) - with a even beefier current cpu Thats a 14% increase. I don't know that much about CPU's, but why are we going down this path? With improved thermals and TDP shouldn't higher clocks be easily achievable? x86 is so dated, and there is a lot more interesting things happening elsewhere: http://en.wikipedia.org/wiki/TRIPS_architecture Please note: That of course for some areas of work, for example: Folding, number crunching, more cores is desirable, I'm just talking about the average joe here. Please note 2: There is a lot of interesting stuff happening in quantum mechanics which is going to translate into CPU's, however thats far away still.
