Hi

I work a lot within premiere pro and after effects and do some light 3d work inside cinema 4d.

what is the best all round cpu for these programs that intel provides.

i had me eye on the 7940x but the 7900x is cheaper and seems to yield similar results.

Anyone got any tips or advice?

    It going to depends on what you are doing in your workflow.  Premiere Pro and Cinema 4d have quite well mutithreaded effects and features which love lots of cores, but After Effects is not well threaded and lots of cores actually slow down performance.  For best After Effects performance the best rated CPU is a 6-core 4.7GHz i7-8700K processor.  See this testing by Puget for the numbers to verify this.  The reason it is outstanding with non-mutithreaded applications is the high basic core clock, i.e. the 4.7GHz Turbo Speed

    The thread is old but Intel CPUs have Quick Sync AMD CPUs do not. That being said it would be best to wait a few more months to see what Intel's 10 nm Alder Lake CPUs can do. Will Alder Lake be the best bang for the buck in 2021? Only time will tell.

    Hey Andy, hope you're doing well. 
    Can you tell me what's the situation now? I need to upgrade my PC for AE and I'm not sure which CPU to get.

    I will building a new workstation and I forget how many post that I have ever read about it watched bunch of videos and finally I am so confused.

    I was thinking to buy i9 7940x but that CPU is really bad for after effects? If it is.. only getting render? I do not have any time issue for rendering. I just want to work on huge project like 4K-6K footage and cinemaDNG codec as a live preview.

    i9 7940x is really bad choose for After Effects? Or the almost the same performance with i7 8700K? everybody is choosing i7 8700K because of price/performance?

    I have been thinking to fix multi-core issue with rendergarden, if it bothers me

    So could you help me out please? I am really so confused what I need to choose

    Yes I know, its about rendering right? But I do not have any render time issue, I just curious about live preview. i9 7940x is worst from i7 8700K? And Have you ever worked with cDNG codec in AE? Its sooooooo slow with i7 8700K and curious how it is with i9 7940x


    Yes, it would be worse with the 7940X than with the 8700K because renders from AE, in its present form, still scales very poorly with more than eight threads.

    I found that out by doing a sample render with cDNG, using a borrowed desktop PC with 8 cores and 16 threads, and discovered that half of the PC's virtual cores went completely unused (0% utilization) during that render. This just goes to show how poorly the current version of AE is multithreaded.

    What's more, with only four cores getting any load, the i9-7940X only runs at 4.1 GHz - noticeably lower than the 4.4 GHz that the i7-8700K runs at under the same conditions. Plus, the Skylake architecture is a tad less efficient than the Coffee Lake architecture.

    Note that this is with standard projects, without using Cinema4D (C4D) at all. If on the other hand your projects incorporate the use of C4D, then yes, that portion of AE is well multithreaded. Thus, for AE, the 7940X is worth it only if you're going to use C4D extensively.
