Codename Haswell: Official launch and test of the Core i7-4770K

Intel chose today, a Saturday to launch its new generation of processors, known as Haswell. And since Haswell is the fourth generation of processors using the name code "i",  it will be marketed with references: Core ix-4000.  
 
Not the entire range will be launched today, we can only approach the performance of desktop processors. Our case concerns therefore the Core i7-4770K, the top of the range Haswell. Is the new architecture really faster? Is the 22nm engraving better controlled? smaller consumption? better overclocking? And what about the graphics performance, expected to be up to 3 times higher compared to Ivy Bridge?
