The Actual highest overclock is 6ghz.It was done on Amd Phenom II Dragon Platform.And yes it is in the world record so its not fake

If you wish to know the worlds fastest processor clock it isn't measured in Ghz. It is measured in something called Petaflops. This type of recording is much faster than any commercial processor will achieve any time soon. It is used for super computers and that is the only place you can currently find this speed

FLOPS - floating-point operations per second
peta - a prefix in the metric system standing for 10^15
Clock rate- refers to the number of cycles per unit of time (usually seconds)
The original post is talking about clock rates, which is measure by its frequency, or hertz. FLOPS has more to do with a processor's ability to perform instructions, which take into account its' clock rate and many other factors such as its' architecture, instruction set, the system its running on, and even the task it is running (smarter use of caches can improve FLOPS by dozens of magnitudes). You can't really talk about FLOPs between processors without taking into account many other things, but clock rate is essentially set for a processor since it is an atribute of it.
If you want to go into the category of measuring processor 'speed' based on flops, CPUs wouldn't even be in the race.
As you mentioned, super computers are in the petaflop range, but many of those super computers actually use a mix of GPUs, GPGPUs, and CPUs to achieve that speed (infact, most of the performance actually comes from the GPUs).
GPUs tend to have much, MUCH, higher FLOPS than CPUs (on the magnitude of 10-100x currently): For comparisson, a i7-3960x has a 64.9275 GFLOPs rating, http://www.brightsid...i.aspx?pageid=5
while a Nvidia GTX 680 has a 3090 GFLOPs rating. http://hexus.net/tec...cs-card/?page=3
These two are pretty much the high end cpu/gpus for 2012, but the trend of GPUs outpacing CPUs in flops have been like this for years.
But since this post has been talking about CPUs, and clock rates, the fastest CPU I've heard of is currently an AMD Bulldozer running at 8580 MHz. http://www.engadget....h-a-8-58ghz-vi/
