4-core @4.3GHz or 6-core @3.5GHz

[Mike Sierra]

Hi.
I'm considering a hardware upgrade from the specs as in my current signature (Asus Rampage IV Extreme, I7-4930K @ 6x 3,90GHz , 32GB DDR3 RAM, Asus ROG Strix GTX 1080) to the following:
ASUS ROG Strix X299-E Gaming board
Corsair Vengeance LPX 32GB, DDR4-4133
and for the cpu either a
6-core Intel Core i7-7800X, 6x 3.50GHz
or a
4-core Intel Core i7-7740X, 4x 4.30GHz
(graphic card unchanged Asus ROG Strix GTX 1080)
The question concerning me is: which CPU can provide better performance for P3D?
If I do a simple multiplication, 4x4.3=17.2 versus 6x3.5=21.0, the 6-core chip gives a higher result, but: is that equal to more capacity? and: will P3D gain profit from that?

Thanks in advance for assistance,
Michael.

Nobody knows 4 cores or 6, with less clocking, or will PREPAR 3D V4 use as many as 4 cores? I also want to know? I'm going to change the hardware can anyone help ?

4 at a higher clock rate has been my experience.

A fast core 0 determines the engines speed ( fps )
The amount of cores help with terrain loading ( prevent blurries and stutters )
Beside that , if you have several addon programs running beside P3D , like a weather engine , cockpit suite software , moving map software etc , you can set an affiniteit mask for P3D and use the free cores for those programs ( prevent small stutters )

Thank you, DJSean, for this clear statement.
I wonder, whether others will contribute or oppose...

For me it works better 4 cores with the highest oc possible. Perhaps in the future with dx12 it will improve.

Hello,
I recommend i7-7740X.
Because I am running i9-7900X with 2 GTX 1080 Ti and 4.5 GHz, satisfactory performance has not been obtained. Also, I have disabled Hyper-Threading, but I did not see any performance change. Improvement can be seen in OC better than that.
However, in the future, considerable performance improvement may occur with correspondence of V4.1 and DX12.
