AMD 5800X3D performance

Agreed! I have a Arctic 420 AIO on my 5800X3D and it never gets over 60c or more than 50% load in MSFS and that with triple 55" @ 4K on a 4090 and 4 more screens on a second GTX1650 GPU. Can post screenshots of RIverTuner if interested. My issues is I can’t engage Frame Generator and I think it is because of the GTX 1650 on the same Mobo. Please, Asobo Can we have networked capabilities so I can run my Avionics displays on a second PC?

im planning to use a second gpu along with a 4080 for external instruments … what do you mean by frame génération doesn’t work because of the additional gpu ?

2 GPUs in a single motherboard = problems.
Tried myself not worth it. Unless you are using a GPU built in the processor, that would be the only way to improve performance on external instruments or fenix a320 for example.

My 3080 handle all pretty well 5800x3D + 3080

so i guess you’re running out video output for your home cockpit ? im in the same situation and still wondering about a smart solution
Im still thinking about additional monitor on LAN via a second pc but i’m not sure about performance

Ryzen 7 5800x3d is a massive improvement over my previous ryzen 5 5600x, slightly more fps but a lot more stability. Hardly any stutters even in crowded airports. When rolling down the runway with Fenix I used to have stutters and fps drops but now it’s butter smooth. Truly love this chip.

Agreed. I see posts all the time from owners of fairly new systems about great FPS but with stuttering being experienced. Since updating to a 5800X3D, I am amazed at how super smooth MSFS has become, even in VR.

Music to my ears! 7800X3D can’t launch soon enough! The only real issue I still have is microstuttering here and there (on a 7700x).

Sorry you are having mixed results running two GPUs. I’ve been doing it for years. Is it ideal? Not my preferred choice but until we get networked PC capabilities my 5800X3D and RTX 4090 and GTX1650 will do just fine.

Yeah baby! Can’t wait for the 7800X3D. If you are considering an upgrade you owe it to yourself to watch this Tom’s Hardware video. AMD X3D CPUs

Thanks, I’ll take a look. Though I’m not considering it at all, will be a day 1 buy if i can. It’s the only reason i got an AM5 board last year

Best of both worlds too this time round, high clocks and cache. I’m very eager to see how they do as it’ll be my in future build for sure. Hopefully this time around I can build a PC with a matching colour scheme, trying to build one during a pandemic was a bit chaotic with the, “it’ll do” approach.

The AMD X3D CPU series are a blessing for the performance of our MSFS sim.
The X3D CPU’s performs much better than the current Intel CPU’s because of the build-in 3D V-Cache.

I was looking forward to the 7800x3d, but AMD will hold it for another 2 months, giving them time to sell the other 3d cache versions (more expensive, of course).

Do you think they are doing that because the difference in performance between the 7800x3d and the other two (7900x3d and 7950x3d) will be irrelevant?

The main reason why this is done is all about profit. These video card vendors have learned that if you hype up your product after months and months and then start selling the low end of the product line model 1st, many people will buy it just because they can’t wait. Therefore, the sales of the higher end product, when introduced later, will be mediocre. Coming out with their highest end product 1st will do well for the same reasons and they can maximize revenue.

I know that, Nvidia and Intel also do that, but I would like to know if the 7800x3d will be enough or if the other two will worth their prices. I think I will just wait until April.

This is strictly speculation on my part, but I think, for games heavily dependent on cache performance like MSFS, we will see no real difference among the 7950X3D / 7900X3D / 7800X3D primarily because all three chips will have 3D VCache on “just” 8 cores. The other higher clocked 8/4 cores on the 7950/7900 wont have VCache and you’re not going to want MSFS running on them anyway, so there usefulness will be dubious at best.

This is why I’m so curious to see how AMD works with Microsoft to make VCached cores preferred for those applications that really need it and prevent those from inadvertently running on non-VChached cores.

AMD have already stated that games that should be run on the chiplet with V-Cache will be identified in a ‘whitelist’. The are not trusting windows scheduler to make the right decision.

Yes, I’ve heard that too. Will it work properly is the next question :slight_smile: and I’m still very curious if it’s bug-free out of the box.

From everything we’ve seen, there is no reason to get anything higher than an 7800x3D if your main use case is MSFS. Higher tiers only make sense for productivity or if it’s super important for you to run specific games that would run faster on the non-Vcache CCD at their absolute maximum possible performance.

Although not directly, we can expect a certain effect in that it will make it easier for MSFS to occupy the VCache side cores by having the VCache side CPU use MSFS and the non-VCache side use another application that the user needs at runtime.
This could be done by offloading the audio software mixer, messaging client, video distribution software, VR OculusLink application, etc. to the non-VCache core.

Conversely, applications that use Simconnect as an add-on to MSFS, etc., may not have much reason to separate into non-VCache cores. This is because these applications communicate with MSFS internally, so the communication latency is longer.
