At 4K (where it matters 😆 ) looks like nearly a tie. Slip in some faster memory for the 13900K and it's a win for Intel.

On a GPU-bound scenario, sure. The X3D still may have an edge in populated hubs, though. 

Based on different reviews, I will probably wait until the 7800X3D is released to see how things play out. Frame Generation has given such a boost to my fps on big airports, that I might postpone an upgrade indefinitely.

Well, which GPU was used for those benchmarks? I mean, roughly 90 FPS in FullHD? Those graphs look like GPU limited already in 1080P to be honest...

They used an RTX 4090.

Interesting, I would never have thought that regarding the FPS number they get in FullHD...

Gaming benchmarks on the previous X3D processor suggested the cache advantages seemed to diminish at higher resolutions (don't ask me why) so I don't find this result too surprising.

I do, irrespective of the cache, 89 FPS for a 4090 in FullHD is rather low, especially because the 1440p result then is 92 FPS suddenly. Talking about the 13900K...

I see your point. 13900k looks like it was being held back, which puts all the results in question. Need more independent test results!

exactly my thinking, or wait it out until Ryzen 8000x3D which supposedly is closer than it may seem in your rear mirror, with another 30% performance boost over the 7900x3D.

"Enabling the EXPO memory profile brings our memory speeds from the stock DDR5-5200 to Ryzen’s sweet spot at DDR5-6000, which yields less than a 1% improvement in performance."

Imagine: Ryzen 7900x3D + RTX 4090 with FrameGeneration set to ON. the above test was DX11, Ultra settings, without FrameGeneration and still 90 fps 😀

My point was Intel's memory controller is acknowledged as superior to AMD and can hand memory speeds that AMD can't touch (eg. 8000 ddr5 is out now). In these benchmarks, the 13900k is being held back by using the same memory as the 7950x3d 'to be fair'. But consumers are not bound by these fairness constraints.

not sure that matters for MSFS for the AMD x3D versions when code can run so much faster in cache memory than in external slower main memory.

The cache size is about 2% of the ram required to load MSFS so faster ram has got to provide some benefit. Otherwise, buy the slowest cheapest ram you can find for your next 7950x3d build... I dare you!

If 7 FPS is 48% then we are all doing our maths wrong.
