Intel's Core i7-3770K (ES) vs i7-2600K vs i7-3960X, nuff said!

We have also included a brief USB 3.0 controller shootout inside, involving the new Z77 (Panther Point) Native USB implementation and other popular solutions.

Prior Reading Disclaimer / Warning:

The Ivy Bridge Core i7-3770K (recent engineering sample) results might or might not be indicative of final retail performance, and is not supported or sanctioned by Intel and their partners. As such, we will refrain from making judgements or opinions.

All test setups were equipped with 16GB of 2133MHz CL9 modules and both LGA1155 processors ran on a Z77 motherboard (brand and model not featured on our site so far).
