Question

Iron

Hello! Tell me on the example of the Intel® Core™ i5 / 6200U processor what maximum frequency should be taken, there are two of them on this site: www.cpu-world.com/CPUs/Core_i5/Intel-Core%20i5-620...
Maximum turbo frequency: 2800 MHz (1 core) , 2700 MHz (2 cores)
What does this mean and what will be the maximum?

Answer 1

As far as I understand this processor is not overclocked. Usually operates at a frequency of 2300, with a heavy load it accelerates automatically to 2800
