It doesn´t make any earth shattering difference, but there is a difference.
Lowering the NB frequency and voltage to have "extra headroom for CPU" is pretty brain dead idea as the NB + L3 caches consume less than 10W in average use.
I agree, i am more happy to run 4.8Ghz CPU with 2600MHz NB than 5Ghz and stock NB.
The first one just gives me more performance, not only in benchmarks but also in everyday usage. Windows feels just a tad snappier especially if you run hither than 1866MHz RAM.
Programs also opens up faster and the overall response time is faster.
Some chips need a lot of extra voltage in order to get the higher NB speeds stable and that can result in a much higher CPU speed.
I guess that is what Mega means.Edited by hurricane28 - 5/3/15 at 8:32am
