I’m building a new PC in anticipation of Nivida releasing the RTX5090 and wanted to see if anyone had experience or thoughts on the best Motherboard/CPU to address the limited by main thread performance limitations.
I already have a high-end Z790/RTX4090/i9-13900KS system and started building another Z790 system with the i9-14900KS on the Asus Dark Hero as I was concerned the next intel processors may take a step back as far as high performance on just one or two threads.
So…in my mind I am thinking using core affinity to maximize FS2020 to use the highest preforming core(s) to get the most from the i9-14900KS but then started thinking, if this PC is dedicated to flight sim only and optimized just for that purpose, would the CPU limits be better addressed using a workstation class build or what other options do we have?
I’m also interested if anyone has expertise in PCI Express gen 4 vs. gen 5 and how that works with GPU’s. I know when the RTX4090 came out there was talk about any performance was being left on the table between PCIe x8 vs. x16 lanes, and I am thinking that the RTX5090 would not be limited using PCIe 5 on x8 as it would be the same as gen4 x16 right, so I could use gen 5 NVMe storage which cuts the lanes down from 16 to 8 for the GPU…
I would also prefer to stick with Intel for a number of personal reasons, so any suggestions of using the AMD solutions while may be valid, it’s not for me (and I don’t want to get into debating the pros and cons of each).
Thanks for anyone who can she their experiences or knowledge in this area.
I understand where you are coming from however just so you know AMD is coming out with their next gen Zen 5 cpu’s and probably be announced in the next month or two. The 14900KS really doesn’t provide any performance gain over the current Ryzen x3d chips with the sim so the new AMD cpu’s should outmatch it by a significant margin.
Well now I’m confused, the title says Ultimate PC, then a contradictory disclaimer stating no AMD
Kidding of course
I too was starting to look at new PC builds, but, with 2024 on the door step and not knowing what specs it will require, alongside code changes that could potentially make better use of our existing hardware, I decided to hold off for now.
If you’re going for Intel, I’d say wait for the 15th gen CPU. They’re going to be a new socket, so at least that should make it future-proof for a little while longer. While any socket that’s currently used by the 14th gen would be outdated already by now.
I’m presently running an i5-13600K and love it. Intel A770 LE GPU.
It does great with FS2020.
I’m going to go with the Intel 15th Gen Arrow Lake CPU this fall when it comes out.
And Battlemage GPU.
Probably the Intel 15th Gen Core i7-15700K.
Will need the new LGA1851 motherboard. Already have DDR5.
You won’t need any upgrade for 2024, only if you want to keep kicking the dinosaur single threaded 2020 along. Even a 5090 will still get stutters on 2020. Likely a 4070 will run 2024 far better with way more going on than a theoretical 5090 would run 2020.
That’s very true I think.
My 4070TI made friends with a Z 790 mobo, 32GB vengeance memory, i5 13600K and a 1000Watt platinum power plant.
Together with a "32 Iiama 4K monitor and Track IR5 it’s a great joy to fligh MSFS2020
I’m confident that my rig will be able to run the 2024 version as well.
Going from 13900KS to 14900KS won’t provide significant changes.
Best is to wait for MSFS2024, and Intel Core Ultra line of products.
Gen5 NVME is useful for speeding up large file transfers. But it will not change your experience in MSFS2020.
Workstation class CPUs have more cores and more pci lanes than desktop CPUs. MSFS 2020 will not benefit from that.
Other than raw power, the only thing that will help with MSFS 2020 experience CPU wise is more CPU cache, which is what current AMD processors have and future Intel processors will most likely have as well.
