Intel QX6850 Quad-Core CPU - 1333MHz FSB
 

For the most part the 266MHz (or 1066MHz quad pumped) FSB has been the big power behind the success of the Core 2, now Intel has upped this to 333MHz (or 1333MHz quad pumped).

Today we are testing out the high-end Core 2 Extreme QX6850 along with some other processors to see if the 1333MHz FSB offers a noticable performance increase over the usual 1066MHz parts.
