Could someone please help me?
It's a very frustrating situation, changin CPU with a technically powerful one that Render in the double of the time
What are your AE memory and multiprocessor settings for both machines?
Note: the clock speed on your older processor is faster. If something is a single-core operation, it could easily be faster on the old machine.
Also, what is the exact version number of AE? CS6's version number should start with 11 (e.g., 11.0.4)
You only changed two things from computer to computer, so one of those two must be the problem. Maybe its made cheaper/poorer quality.
The 5820K is supposed to be faster than the 4670k since yeah it's 200mhz slower but it's a 6 core and with HT so for AE it's a 12 core (even if HT is not a real core)
2 more core should "beat" 200mhz less the fact is that is really slower
My AE Version anyway is 18.104.22.168
My settings for MultiProcessing is... Nothing
I mean I don't enable multiprocessing I just put as much RAM as I can for AE, that's all so the configuration is pretty similar for both machines, I just imported a video that I rendered on OLD pc on the NEW one and try a render
You would THINK that more but slower processors would beat out fewer, but faster processors. That's not always the case in AE -- some effects are constrained to using just ONE processor, and guess which machine wins that race?
Follow the link Szalam provided for memory settings. You'll learn that sometimes AE is really counter-intuitive in the way you'd expect it to work.
