I'm trying to encode a video 2048x2048 @ 25Hz using the last generation of Intel processor Haswell (i7-4770).
The technical specs said that Haswell processor can encode 4K videos @ 25fps. Unfortunately I can only get 15fps with a resolution of 2048x2048.
Does the Intel can really offer these performances?
What kind of problems can occur for not getting the right frequency?
