A few days ago, sources have revealed to us, Intel's Core i5 (Lynnfield) will feature a lower QPI multiplier than Core i7.
Intel's 5 Series mobos will be switched to single-chip design, and the PCIE 2.0 controller will be integrated into the CPU. Even this they use QPI bus inside the CPU to connect the PCIE interface, and use the DMI bus to connect with the ICH.
As we know, QPI restricts the CPU's overclocking performance. Take the Core i7 965 as an example, it comes with 6.4GT/s QPI data rate, 24x multiplier and 133MHz BCLK. Due to the limit of QPI speed (8GT/s), its maximum BCLK can only achieve 166MHz at 24x.
But according to our source, the QPI multiplier of Core i5 will be set lower at 16x, so you'll get a higher BCLK around 250MHz. When you overclock the BCLK, the QPI interface will overclock as well.
