At the IDF 2013 held in Beijing, China, Intel gave more details about the upcoming Haswell processor focusing on it’s overclockability. In the current platform, voltage regulators are external on the mainboard. With Haswell, this are all integrated into the processor. That greatly improves the overclockability even on the lesser known brands since there aren’t corners to cut. Another improvement is that the current LGA1155 Core i5/i7, you can’t really overclock that far as BCLK is always stucked at 100MHz. With the new design, you can start from 100MHz, 125MHz or 167MHz with a +/- of 5-7 %.
