hey guys i've come across some interesting information regarding mainstream processors for laptops especially those available from dell namely the T4200 an the T6400 i was trying to figure out what is the
real difference between the two (because one costs
60US dollars more than the other) and this week i have discovered they're basically
identical !!! i.e.(both variations of the
penryn series) according to this spec sheet provided by intel (links below) the only difference is the cache size and according to some benchmarking reviews done (google) very little difference in terms of performance so if you guys want to buy ah laptop an they have these two listed save your money an get the t4200 you'll save at least 60 US well i hope this helps anyone who's in the market for a laptop and are faced with this processor decision!
