The "K" in Intel CPU's

Seriously "noob" question, but what does the "K" in a processor signify?

What's the difference between a 4690 and a 4690K?

Many thanks!
 
The addition of a "K" indicates that the processor's clock multiplier is "unlocKed", making it suitable for overclocking.
 
4690 vs 4690K is also "Haswell Refresh" vs "Devil's Canyon" (4690K should run cooler)
4790 vs 4790K the same + 400Mhz more for the K

and the unlocked multi.
 
The only K CPU you might consider is the i7 4790K, as it has higher clocks than its non-K counterpart. Otherwise, go with a non-K CPU.
 
Dont forget that even a non-k i5/i7 can be turbo-bin overclocked pretty significantly. You can get almost all the way to the max achievable overclock just playing with the turbo bins.
 
Probably they knew that if they kept the turbo bin thingy just like it was on SB, yo could achieve the same clocks than most mild K sku average overvlocks.
 
"K" is potassium in the Periodic Table. Intel has fortified these processors with extra potassium and due to this they are able to overlock.

/no, not really, but it sounds fun...
 
I always thought it was a clever nod to AMD's "Black Edition" processors, which were also unlocked.
