Hello guys

I want to upgrade my system but my question is:

Need After Effects more Cores or higher GHz to Render fast as possible?

Or is both of them important?

I mean a CPU like an Intel Xeon Processor E5-2699 v4 (2,20 GHz / turbo: 3,60 GHz)

Or Intel Core i7-7820X (3,60 GHz / turbo: 4,30 GHz)

Xeon: Intel® Xeon® Processor E5-2699 v4 (55M Cache, 2.20 GHz) Produktspezifikationen

Core X: Intel® Core™ i7-7820X X-series Processor (11M Cache, up to 4.30 GHz) Produktspezifikationen

My System: (Today)

Intel Core I7 4790K 4GHz 4Cores

32GB Ram

Nvidea GeaForce GTX 980 ti

SSD m2 512GB

Can you advise me?

For After Effects only, processor speed is more important than the number of cores.

    Intel Core i7 4790K 4Cores (4GHz / turbo 4,5) better is as the new

    Intel Core i7-7820X 8Cores (3,60 GHz / turbo: 4,30 GHz)

    CPU architecture also matters here. Due to the lower system memory bandwidth, the i7-4790K (which officially runs only DDR3-1600 memory) at an all-core speed that's been overclocked to 4.5 GHz (default all-core Turbo speed: 4.2 GHz) is actually slower than the i7-7700 (non-K, running DDR4-2400 memory) at its default, non-overclockable all-core Turbo speed of 4.0 GHz (based on my own testing using all cores and threads). By extension, it is slower than the i7-7820X (default Turbo: 4.1 GHz on all cores) even in single-threaded applications.
