I am in the process of building a new PC for MSFS2020 and need some help selecting the processor.  I am looking at the I9-10900KF, do you see any issues going with the KF processor over the standard K processor as it relates to MSFS2020?  The system would be a I9-10900KF, RTX-3090 and 32 GB of memory.  I don't know enough about the hardware side of things to understand the difference between the KF and K processors and how it affects performance in MSFS2020.  Any ideas?

Thanks,

John

They are close enough to identical. If anything the KF may be faster by an infinitesimal amount as it lacks a GPU to generate heat.

Basically the only practical difference:

• the KF needs your 3090 to work and the display ports on your MB will be disabled - you have to use the 3090.   
• the K has a low performance GPU built in and is capable of generating a display of sorts (very poor quality) on the MB display ports without any other GPU at all.

So, you don't see any issues with that setup with regard to MSFS2020?

Absolutely not, no difference performance-wise. I've got one.

Perfect, thank you!

The difference is irrelevant to FS2020.

 

The KS may be faster yes Intel is at it again reports they are releasing a 10900KS milking it i think, good news for Intel AMD unavailable Intel make big profits and market share.

This seems to indicate the 10900K is (slightly) better, so the 10900KF is the slightly slower processor - if you are paying that much anyway - but on the other hand you can't really go wrong with either they are so similar! 🙂

I think from a consumer perspective I would probably go for the more mainstream 10900K processor but it really is much of a muchness. So jellous! 🙂

Went with the I9-10900KF, RTX 3090 24gb and 64gb of memory, should be here March 8th.  Cost about 2k more than I was planning but, just don't tell my wife.  LOL  Thanks for your help guys!

No entertaining an AMD CPU? They are smoking fast, and generally a bit cheaper. 

After decades with Intel I've recently switched from a i9900K to AMD and really love the 5950X for daily usage and particularly for MSFS.

It's pretty hard to get your hands on AMD CPUs right now. I really like my 3950X, I'd like a 5950X but I don't have time to sit clicking the refresh button all day on weekdays to try to snag one.  At this point we are so long into the release cycle that I might just suck it up and wait for AM5 and whatever comes next for my next CPU upgrade.  Really need a GPU though.

The fastest AMD 16-core CPUs have a Peak Power Target (the most power they will every draw from the socket even under boost) of 142W

These Intel 14nm++++++ (I forget how many pluses we are on right now) CPUs have a PL2 turbo power draw of 250W, for both the 10-core current series and the upcoming Rocket Lake that only has 8 cores.

Granted you typically only hit these huge power draws under heavy multicore load, but Intel's process is way behind, and I hate to support rewarming over the same thing for 6+ years.

I am really happy with my AMD CPU... not so much on my 5700XT in the sim. Other games it is fantastic though.

I could have said that myself!😊

We have a very similiar PC. Mostly with the 5700XT I have had to keep old drivers, otherwise I get constant CTDs in the sim.
