I plan on upgrading from a 10900K soon. I’m wondering should I go with the 9800X3D or 14900K? I know the 285K has done poorly by comparison to the 14900K.
With FG Enabled and optimized settings I get about 80 fps but the issue has been the 1% lows and they drop to about 30 sometimes and induce stutter. I’ve overclocked my 10900K to 5.3 GHz and the 1% lows are still pretty bad.
What do you all recommend?
Thanks!
I used to have an i9-10900K / RTX 3070 and now have an i9-14900KF / RTX 4090 and i9-13900K / RTX 4080 Super. While I am not having issues with the latter two CPUs because I got an RMA on both and upgraded my BIOS I would avoid them. You can read up on their issues.
Ah so 13900K and 14900K are a no go… I’ve heard some reports about the CPU’s degrading over time but that Intel released an update to stop that issue but people say only time will tell if it really was fixed?
Without the issues how’s your performance been in the sim with the 14900K as far as 1% lows?
I’m not sure about 1% lows but I play maxed out and can fly for hours on end and it’s silky smooth using TrackIR. My monitor is 27” 2560x1440p @ 180Hz.
My personal preference was and is intel for quite a while now, but about a month ago I was facing the same dilemma and decided to go buy amd cpu. I hope that intel will feel the backlash for the poor design of their latest generations and clean up their game, until then I’d rather buy the less prefered name but with the better product.
Btw I had no issues with the amd cpu I bought
Oh nice! I’m flying at 4K at the moment but it’s been bugging me how every few seconds I notice the stuttering. It usually happens when my 1% lows dip below 60 frames with frame gen on. You can check your 1% lows with Nvidia Overlay.
Moved to User Support Hub as OP is requesting assistance.
In MSFS 2020, the AMD X3D processors were clearly superior. For 2024 it’s less clear. The new sim still likes the extra 3D cache from AMD, but the extra cores and speed from the 13/14900 KS versions make the intel chips more competitive with the improved multi-core optimisation.
Either will be better than your current 10th gen, and for MSFS either might be better then the newest Core Ultra 9 285K.
2024 has additional (self-inflicted) issues that impact performance, particularly the streaming of scenery and other items. You may find that other aspects of your PC build can help a bit with these, like having lots of fast ram and a large cache set up on a fast m2 ssd, fast hard-wired data connection etc.
I have a 13900 KS S and it works very well in both sims. All the motherboard manufacturers now have BIOS updates that reduce the original ridiculous 4000 watt power max settings that could cause issues, although I tweaked this manually along with voltage & LLC when I first installed it.
You can also help performance and minimise noise by having all the PC’s fans linked via the Fan Control app. Whichever CPU you choose, I would definitely recommend this: https://getfancontrol.com/
I upgraded from a 10900k to a 7800X3D last year and I was super happy. In MSFS2024 I have a super smooth experience stutters free locked at 60 FPS. In my experience 24 runs a bit smoother then 2020. All cores are utilized and temps are lower then MS2020. Probably intel CPU will also perform better in 24 then in 20. Note that with AM5 platform you will able to upgrade at least for the next 2/3 years without changing your mobo
I would wait until the benchmarks of the other X3D chips come out, propably in january. 9800X3D is looking like it will be the best value for money. But they may have fixed the latency issues with games of the higher end versions 9900X3D and 9950X3D, if you want to throw money at the fastest option. If they aren’t much faster like in the last generation i will probably buy the 9800X3D. But currently i have the 7950X3D and i use the non-cache cores for everything but MSFS so the cache cores are fully available to the game.
After quite a bit of testing (posted in various threads here) I’ve done the same with my 7950X3D. I use Process Lasso to assign the sim to the vCache cores, and everything else to the non-Vcache cores. I do quite a bit of encoding with Handbrake, and for that app having all 16-cores is a benefit. I don’t fly when I’m doing that task, since Handbrake will use as much CPU power as you can give it. CPU’s with split cores (like the 7950X3D and Intel’s P-core/E-core designs) are great. I probably could fly while using Handbrake assigned to the non-Vcache cores, since the processes would mostly stay out of each other’s way. I might try that test, just for fun.
To focus on the thread topic better, I think the 7950X3D is a great CPU for this sim, but you have to be willing to do some work tuning it. A single chiplet CPU like the 9800X3D (or 7800X3D on lower budget) is perfect if you just want to let Windows handle the core assignments.
I left Intel long ago. The i9-14900K is a great CPU, but it has issues that makes me question its suitability for my needs. The OP might get one and it would work fine for a long time. It’s no slouch, and would be a significant upgrade from the 10900K.
I (seriously) recommend more VRAM for FS24.
It’s a known weakness at the moment.
You haven’t mentioned which GPU you have, 8GB is probably not enough.
There’s a reason the humble 1080TI has 11GB VRAM.
Yep. I also have Netgear’s low cost 1Gig unmanaged 4-port switch. It has a small memory buffer, which definitely reduced dropouts when streaming on an older HD TV.
I think it reduces packet loss, which obviously impacts data streaming.
Our broadband router feeds the switch, which then feeds the PCs.
Wi-Fi has been hyped and overpromised. Avoid.
I’m running a i9-14900KF, I had stability issues with it until I dropped the number of active cores from 32 to 30 and dropped my P Core ratio from 57 to 55. Technically it’s lowered performance but I can’t tell. Now 2024 runs smooth as could be for hours on end. I’m running a 4080 super for my GPU. Just food for thought if you go 14thgen intel
I wasn’t having issues with MSFS / MSFS 2024 but was in War Thunder (it was crashing). I did this and it fixed it.
I used to discourage buying AMD CPUs, but now I wholeheartedly recommend AMD X3D series. After 30 years of using Intel, I switched to AMD and have no regrets. Until recently, I had an Intel i9 13900K but I returned it to Intel for obvious reasons and they refunded my money. I bought a Ryzen 7 7800X3D and on its release day a Ryzen 7 9800X3D. I gave the Ryzen 7 7800X3D to my son. I don’t regret switching from Intel to AMD and plan to stick with AMD CPUs for a long time because (right now) there’s nothing better for gaming.
I’ve had no issues with AMD Ryzen 7 9800X3D or the motherboards designed for Ryzen X3D CPUs. Additionally, my latest CPU, the Ryzen 7 9800X3D stays cool during gaming like snow in Antarctica 
I’m right there with you Cipher. I’m in the exact same boat as you, I can’t decide between the AMD Ryzen 7 9800x3d and the Intel Core i7-14700k. Where I’m struggling is the only “gaming” I do is flight sim, the rest of the time I’m using the computer for daily tasks, internet surfing etc. I currently have a 1080ti that I’m going to keep riding with until I can save up enough $ to buy a new card.
From what I can tell with the two builds I’m looking at, the AMD would be $283 more. Wondering if I go with the intel and take the savings for a new GPU. Let me know what you decide to do!
I faced the same choice as you. I was debating whether to stick with Intel or switch to AMD. After 30 years of using Intel, I decided to make the switch to AMD, and I have no regrets. If I don’t regret it, you won’t either - you’ll be very satisfied with Ryzen 7 9800X3D CPU.
The first thing I would do is check the sim’s built in fps display to see if it’s the CPU or GPU causing the stutter. If it’s the GPU spiking, then it’s unlikely a CPU upgrade will help.
If you do want to upgrade the CPU, maybe consider the 7800x3d. It’ll still perform great at a lower price.
Hi WillB, and welcome to the forum.
Of the two CPU’s mentioned, I think the 9800X3D would be significantly better for MSFS than the i7. If you particularly wanted to use Intel, then an i9 (preferably KS or KS S variant) would get you closer in performance to the AMD, but would probably cost even more and it will require more beefy cooling.
I am no expert like some of the other posters, but if your other uses for the PC are regular daily stuff like work & browsing then I doubt the higher intel core count would make any difference.
