This summer I want to upgrade my 5820K  6 core processor running at 4.3 GHz.

A 8700 6 core processor might run at 4.7-4.8 Ghz in my system ( triple view which is more taxing ) .

However , Rob A has a very good experience with his 10 core 7900 x processor compared to his former 5960 , which is the same series as mine.

The larger the L2 + L3 cache the higher the framerate as it seems.

You never know dave, that CRJ of yours might even fly straight on a 6 cores.

In both cases HT was off. No affinity mask.

Try with HT and AM 4052.

The benefit of two additional cores is that you can give the main P3D job and add-ons some breathing space. 

Lets look at the attached picture from my current flight with FSLabs A320 and zoom to the Task Manager. Yellow-marked logical cores provide that breathing space. Notice, that the main P3D core is not completely used, which is some achievement with FSLabs. Without the affinity mask, the main P3D thread would take 100% of the first core. In my setup, masking-out the first physical core increased FPS with FSLabs by 20%. The reason for skipping the 6th logical core is this - when you combine threads of red and blue cores to one physical core (e.g. with AM 4084), the main P3D thread that runs on the red core will be throttled by the blue texture-loading thread. And why HT on? Look at the last six cores – they all work very hard to load those textures and they do it well, because this is a kind of task where HT technology is very efficient.

Ok have no 7900, have a7920  and testing a 7980xe 

I have not seen big diff to a 7700k/5.2ghz compared  to a 5ghz  7920x or the 7980xe /4.8ghz

The 7700k was the fastest then 7920x and last the 7980xe when it mesure the framrate all inside 2% difference

Keep in mind that the 7980XE has a lot of cash 

 

 

The moment I disabled HT and left out the AM , my terrain cores activity dropped a lot and the blurries I experienced near Frankfurt ( FTX Germany + AS Frankfurt + Heavy weather from ASP4 ) were gone ....

My core 0 during FS is 97-98% .. 

I always used HT + AM up to V4.0 , but V4.1 is better of with all 6 cores on my system ...

Thanks Hasse.

The 7980 XE looks great , but it costs a lot ... 

I have a triple view real size cockpit with the server running P3D and several Prosim and cockpit modules.

All other Prosim modules , AS + ASCA + PSXseeconTraffic on a cliënt pc. 

I am curious about your 7970 XE findings and If it would be the processor for my triple view setup.
