People are overclocking using liquid Nitrogen for getting records but that is not something you can use practically, the backlash against what Intel did is that this overclock was hard to pull for regular use, it used so much power for cooling that some people on reddit suggested that you can't pull it from a regular power wall socket in some countries, also the demo was run for a few seconds that implies that if you would run it for a few minutes you may lose the ability to cool it enough and you will get less frequency. A really cool feature the new AMD CPUs have is that they have a very well implemented turbo, if you give it good cooling it will know how to exploit it and give you more power. As a side note, is a weird feeling running a 4 core/4 threads CPU when now workstation CPUs could reach up to 64 threads
