If I use 2.5GHz processor on 4K image, am I right to think...

that I have only 2.5 billion / 8.3 million = 301.2 operations per clock cycle to work on and optimize with?

2.5 billion refers to that 2.5 GHz processing speed and 8.3 million refers to the total number of pixels in 4K image.

Or in other way of saying, to what extent will a 4K image (compare to lower resolution images) going to take its toll on the computer's processing capacity? Is it multiplicative or additive?

Note: I am a …
