Question on number of Cores v GHz of a computer

[john82088]

I am looking at buying a new computer. I have been under the impression with flying xplane that the number of cores a computer has is not as important as the GHz of the computer for better xplane performance. If that is correct, is this the best computer for xplane

Intel® Core™ Processor i7-7740X Quad-Core 4.3GHz 8MB Intel Smart Cache LGA2066 

or this one

Intel® Core™ Processor i7-7820X Eight-Core 3.6GHz 11MB Intel Smart Cache LGA2066

 

Thanks for any computer advice anyone can offer.

The  Graphic card is the bottleneck , both processors will do nicely.
Invest your money in the graphics.

FSX depends on the CPU
X-Plane depends for a huge part on the graphic card.

Thank you for the advice. Much appreciated.

It depends on what settings you prefer in X-Plane.

Some settings depends on CPU and other on GPU.

Take a look at this video from Laminar Research.

Thank you for the video. Unfortunately, they do not mention the number of cores. Less cores more GHz or more cores less GHz is what I am trying to determine before my purchase. Thanks though for your time!

At the moment X-Plane is not very good at running on many cores. This may be changed in future. But hard to say when and if.

So the best CPU will basically be the CPU with highest GHz pr core.

I.e. a 32 core CPU with 3GHz will most likely performe worse then a 8 core CPU with 4.5GHz

You can read more here from the x-plane developers.

Thank you - that is a big help. I will go then lower cores and higher GHz.

I appreciate it.
