The fellas at PC Perspective have the Intel Core i7-3930K Sandy Bridge-E CPU strapped to the test bench today for a little review action. Here's a quote to get you started: The Core i7-3930K runs at about 100 MHz slower than the Core i7-3960X (I say "about" because depending on the core usage count, Turbo Boost may have that at 0 MHz or 200 MHz in a single case) and the program and application performance seen with that frequency gap is about what you would expect: 2.5% in areas where the CPU performance is a straight bottleneck. If the performance of the Core i7-3960X impressed you in our first review, then this should as well. If it didn't, the Core i7-3930K isn't going to change your mind.
