There is a thread on our hardware board that has some discussion about the new Intel CPU's that were released today:
http://yabb.jriver.com/interact/index.php?topic=71600.0Ivy Bridge class CPU's use 22nm technology, so more transistors can be squeezed into the same space, and power consumption is lowered.
It is said that they are also a little faster and that the on board graphics capabilities are significantly faster.
Please use that thread for discussion.
