All of this may change after the upcoming patch which they said in the latest Dev Q&A is going to improve the threading of the sim to give a performance uplift for people who are ‘limited by Mainthread’.
I’d recommend waiting for that before running off to get a new CPU.
I think single core performance is still going to be critical just because of the nature of simulation
It may not be a binding constraint for 4K after the patch but may still be relevant for lower resolution displays.
Hi RappeFiets, Welcome to the community
I think you may have misunderstood something. The gamer nexus video explained that there is no such thing as dual channel or quad channel RAM sticks. It is the platform i.e. CPU and motherboard. that determines if you RAM works in dual channel or quad channel mode - and that X570 boards and the AMD 5000 CPU’s are not quad channel design.
What gamer nexus discovered was that their 4 x 8GB RAM sticks showed about 10% performance increase compared to their 2 x 16GB RAM sticks. Using the 4 sticks does not give the platform quad channel memory. The seen performance appears to be due to the number of ranks on the RAM sticks. i.e single or dual ranks
My understanding of the conclusion given by gamer nexus ‘expert’ is that he is awaiting input (better opinion) from an ‘expert’ called Wendell
Looking a bit better than I was expecting.
Logical that on 4K there’s no difference (GPU limited), but on the other 2 resolutions that’s around a 30% increase. Pretty good.
I recieve my 5600X next monday, can’t wait to test everything out…
Please update!
Very interesting whats the difference between 3900x/xt and 5900x in 4K. It seems to me I hastened to buy 3900xt…
Here is a Dutch article about CPU/GPU and MSFS: https://tweakers.net/reviews/8356/microsoft-flight-simulator-op-reis-met-ryzen-5000-en-geforce-3000.html
You’re probably correct.
Even so, the 3900 doesn’t really bring anything to MSFS over the 3600/3700, just like the 5900X doesn’t really bring anything over the 5600X.
MSFS (and almost all games at that) simply can not utilize all those extra cores/threads.
Any ideas what’s causing the slight ding on the 5900x fps? It’s not really significant, and maybe it’s just error margins, but if it’s consistent or magnified by future updates, one might consider a lesser processor that costs less, or going for the 5950x because of its gain in other multithreaded apps.
Folks have mentioned latency due to how the cores are split between the 5900x and 5800x. However, compared to the 5950x I’d expect the 5900x might have the edge sometimes due to potentially boosting higher and generating less heat. Maybe that’s a non-issue since all the extra cores aren’t going to be doing anything anyway in Flight Simulator.
the 5800X also has 100MHz higher clockspeeds than the 5900X, and yes, it does have 2 CCX’s, which can add a bit of latency.
In general though; if you’re only going to be gaming/simming, stick with the 5600X or 5800X, if you’ll be doing rendering/video editing, the 5900X might be worth it for you.
Thanks. I do quite a bit of video editing and 3D work. I have a 5900 in my hands, or hypothetically a 5950 in 3 weeks if this order ships. I’m weighing the pros and cons of just throwing the 5900 in now and canceling the 5950. Money is not a huge concern here, but if the 5900 has the edge in some gaming situations, and performance is only marginally better in other multi-threaded apps on the 5950, I might as well just use what I have. I’m trying to talk myself into patience though if Flight Simulator is taking a ding, I’m looking at these huge 4k video edits, and since the hard to get 5950 is already in the bag hopefully.
Take it with a pinch of salt as well, it could’ve been a bad 5900x versus an awesome 5600x bin.
The silicon lottery eh? I was surprised because they’re all scoring pretty much the same in single threaded performance.
