Why not stick with a proven solution 8700K, 9700K, or 8600K?

Hey, stop discouraging people from becoming Guinea pigs for AMD. How will we ever know what to buy?

some examples one of the first to brake 4ghz with Fx57 and member of 8ghz club fx8320 8.4ghz.

Ah the AMD FX57.  I had one of those way back when (2005 or so?) and it was a great clocker.  I was the cpu of choice, for a time anyway, for FS2004, in my opinion.  I think I was just under 4 ghz, that was the holy grail back then.

Good question.  So looking at roughly the same price point as the AMD 3700 I see an i7 8700K Coffee Lake 3.2GHz and an i7 9700K 3.6GHz.  So same question, would I notice any significant performance increase over what I have?  Another point to add....I am not the most computer savvy guy and AMD's ease of over clocking is appealing to me, although I also understand that there's not much head room to increase it by a large amount.  Isn't AMD's higher GHz a good thing?

 The thing is, it isn't higher. The 3700X base is 3.6 and boosts to 4.4. The 8700K base is 3.7 boosting to 4.7 (I run mine with the first two cores at 5.0 and the rest at 4.9 without any mods to the cpu) and the 9700K base is 3.6 with the turbo at 4.9. I wouldn't say the AMD overclocks any easier than the Intel chips, but they sure don't overclock as far.

you run the sim at 4.9ghz the 5.0ghz is only when when an app use 2cores, its a common that misstake to think that 2cores run 5ghz then the rest 4 cores at 4.9ghz.

the X299 2066 cpus that you can clock cores with differnt multis.

You have me at a loss here for what you are trying to say? Are you saying that an X299 can't overclock individual cores to different speeds? If so you are wrong the multiplier is selectable per core. I think you are also assuming Dave_YVR hasn't assigned the tasks to specific cores.

my eng is bad, yes X299 you can do that and mainstream 1151 you can not

50 to 65%, so not 100%. Have you been able to maximize the CPU usage to 100% by doing heavy scenery load cases? Set texture resolution to the max and LOD to 6.5 and fly/slew around at FL350. My big question  is just have many threads can P3D really make use of: 16  in a 9900K, 20 in a 7900x, 24 in a 3900x, 32 in a 3950x ??

One of the problems I have about this sort of question is that most only ever refer to P3D flatly and not globally in other words you need to look at how many plug ins and add-ons are going to be making calls on your system and on P3D. My objective isn't to get all cores to 100% because you your system will crash if it does, in fact I look for ways to lower the load without major quality hits to the image. My target was to get a smooth sim with the add ons I use at 4K and that's why I opted for the best of both worlds - high core count (at the time) and high overclocking ability. I was lucky my CPU will actually run 6 cores at 5GHz and the rest at 4.8 ( after delidding and my cooling helps a lot) but frankly the 2% improvement I measured over what I have now 24x7 wasn't worth the voltage.  I think somewhere between 8 and 12 cores is ideal however I am keen to see the difference with AMD's version of hyperthreading after a couple of bios updates-.

OK understood cheers - yes it is a big plus for the X299 and I found using that tune-ability in conjunction with Process Lasso has balanced the load on my CPU very well. I frankly in the last year or so am the happiest I have been with P3D and the other flight sim on my system.

i have 2pcs 2066 I9 delidded cpus , 7920x and 7980XE that one do 5ghz on water HToff on all 18cores

Tested my work horse AMD 1800X in p3d clocked to 4.1ghz with 3600mhz c16 mems the diff was quite big 10 15 fps , with locked 30fps the 1800X strugled with dips to 20-25fps the 9900k hold the 30fps all the time , that with same settings in p3d.

Thanks for your input.  Curious, what are your P3D settings?  And any idea how many frames you could be getting with your 9900K if not locked at 30?  I'm still uncertain if I want to go through a potentially big hassle of upgrading my CPU and motherboard to get the most out of my new RTX2060 card or just leave well enough alone. I know this comment will drive many folks here crazy, but I've never overclocked or changed the BIOS of anything...ever....and I don't know if I want to try to find the most trustworthy youtube video to teach me how.

That Time Spy result is good (excellent actually) I frankly think largely due to the the 2x 2030Ti - nice to have.

As I said I dropped back in clocks because I was not comfortable with the voltage under full P3D load at 5GHZ. I followed Asus advice on not cranking the weaker cores (2) they identify in the BIOS and found that dropping all cores back the 100MHz took a full 0.175 volts off the cores and 8C at idle for a 2% loss in Geek Bench and Time Spy and no discernable difference in P3D. Having 10 Cores @ 4.8- at 36C idle in 23C room will do me for now. The only time I get stutters is when I play around with texture size bumping it up from 10 to 11 - 12 that makes things interesting (sub optimal)  at 4k when you jump out of the plane and start admiring the scenery. 

The OP said he is running a GTX 2060 and I assume that is at 1080p I think he will be fine with a stock 3700X using PBO

I would go for the Ryzen.

Why?

Cause Intel sh*ts on us just as well as NVIDIA does. 

[joemiller 269]

AMD is catching up very quickly. Today's reviews are showing about 5 points difference with Intel ahead in single thread.  Those "roughly" 5 points equals to... very likely nothing in the real-world. So when people say Intel is the best or the top CPU, honestly , it means little to nothing now.  For P3D to react or "feel" any difference you need to count by the Ghz.  So 4.5 to 5.1, hardly any difference to P3D. However, bring a 5.5 Ghz or 6Ghz CPU, then yes, there will be a good performance increase. 

Obviously Intel and AMD can build 6Ghz CPU as of long ago, but that's the point, milk their way up to that point, so the filthy rich can continue to be filthy rich.

And apparently rather than trying to o/c the core speed, one should o/c the Infinity Fabric and Memory settings. Several Youtube sites (like Gamers Nexus) have done this with good results!
