Tom’s Hardware MSFS results at 1080p. The 5800X3D still kills them all.
To quote Tom’s Hardware:
"The Ryzen 7 5800X3D is simply outstanding in this title, highlighting that the chip can provide huge speedups in some titles. However, that can skew overall rankings. This is why the chip is, on average, the fastest gaming chip in the world, but be aware that can change drastically based on the game you’re playing.
The stock 7950X and 7600X lead the 12900K and 12600K by ~14%. The Intel 12900K and 12600K profit heavily from overclocking, gaining 19% and 16%, respectively, while the Ryzen 7000 chips gain roughly 5% from tuning. Despite Alder’s big overclocking gains, the tuned Ryzen chips land within a few percent of their price-comparable competitors."
