Core i7-4770K 4.8 GHz aircooled and with only 0.9 Volt @ Ocaholic
 

Only a few days ago we found a CPU-Z validation which shows an upcoming Intel Core i7-4770K which has been driven with more than 7 GHz. It's obvious that this CPU has been cooled using liquid nitrogen and therefore those clocks are unreachable for normal users. Now our forum member "Validator" found another validation which shows a Core i7-4770K running at 4.8 GHz and only 0.9 Volt.
