Dave68 Posted September 8, 2023 Share Posted September 8, 2023 Is there any CPU-limited situation in MSFS 2020 where the Ryzen 9 7950X will overtake the Ryzen 7 7800X3D? I've read reviews about the 7800X3D and the charts show that it's faster than the 7950X in MSFS 2020 but I was wondering if there were certain situations in this game where there are exceptions? For example, does a 7950X beat the 7800X3D when using the Just Flight BAe 146 inside the cockpit and the terrain level of detail set to 400 at 1920x1080 (with rendering resolution scale set to 200), and full 3rd party AI Aircraft traffic? I'm just wondering if the huge L3 cache of the Ryzen 7800X3D helps only certain CPU limited situations in MSFS 2020 more than the increased clockspeed/IPC of the 7950X and if other CPU limited situations in MSFS 2020 benefit more from increased clocked speed/IPC than the a huge L3 cache of the 7800X3D? Right now I have a 5800X3D but was considering upgrading to a 7800X3D or a 7950X. Link to comment Share on other sites More sharing options...
CrowDrivr Posted September 10, 2023 Share Posted September 10, 2023 This video is not about msfs but may be of interest. As you know to go from 5800X3D to 7800X3D or 7950X you need: a new motherboard (AM5), RAM (DDR5), and possibly a bigger power supply. But since you are going for it, I would get the 7800X3D which is reliable and rugged. The 7950X does not seem to be so (so they say). Or wait for the 8000 series X3D which are also AM5/DDR5 (rumors are they will be cheaper too). Link to comment Share on other sites More sharing options...
CrowDrivr Posted September 10, 2023 Share Posted September 10, 2023 I have an Ryzen 7 5800X3D so I only have experience with that one (probably like you). Maybe somebody else has experience with an upgrade and have had 2 or more AMD X3D gpus ? Link to comment Share on other sites More sharing options...
Dave68 Posted September 11, 2023 Author Share Posted September 11, 2023 Is the terrain level of detail be something that would benefit from a huge L3 cache in MSFS 2020? Would a complex study-level 3rd party aircraft while being inside the cockpit benefit less from a huge L3 cache but more from IPC/clockspeed?

I recall seeing a hardware onboxed review where MSFS benefitted massively from it. Have to ask though, why do you describe them as "reliable and rugged"? I think they're just as reliable as any other CPU. Also, I don't think any CPU is "rugged"; in fact, they're quite delicate - especially the PGA pins of AM5...

See the below screenshot from this a Hardware unboxed video. When CPU limited, the 5800x3d makes a massive difference.
