Large Ivy Bridge 3570K vs Sandy Bridge comparison.

[xdan]

Keeping in mind that 2600K has more cache.

+1
It was a mistake from the begining to compare i5 2500K 6MB L3 cache with i7 2600K 8MB L3 cache.
L3 cache has it's role and in some application make's a big difference.
2600K benefits best from HT but bigger cache helps too quite qood.
Here are some of my results with my 2500K.
More results tomorow.

Stock results are looking pretty good 7-10% and in some cases will be probably 13-15%.
Average will be probably 10% improvement as it was sad from the begining.
What it's strange in both Eggy results and mine is that after overclock to 4.5ghz the improvement of IB drops 40-50%.
May be some early imature bioses which hinder performance of IB during overclock?
Or higher cores temperatures to IB which affects performance.
