I recently saw the price of new i7 at newegg.com. i7 860 (2.8GHz)-$289.99 (Ringgit Malaysia 1004) i7 870 (2.93GHz)-549.99 (Ringgit Malaysia 2289) They have no differences between each other except for the clockspeed. Why the differences are so big?
More aboutexpansive compared
best way to put it, Intel likes major price jumps.
It like asking why is there a $700 difference 920 and 975 when there only 600 MHz and a 1.6 GT/s QPI difference. Intel just likes the price difference.
Because Intel price them that way. The same can be said for the i7 920 and the i7 950.
