Do the Core i5-13400F and GeForce RTX 5090 bottleneck each other?

Yes. At 1080p (1920 x 1080) the Core i5-13400F is the limit and holds the GeForce RTX 5090 back by about 44.6%, for roughly 137 fps on High. Low. At 137 fps the imbalance costs you headroom rather than playability.

How many fps do the Core i5-13400F and GeForce RTX 5090 get at 1080p (1920 x 1080)?

Around 137 fps on the High preset. The Core i5-13400F tops out near 142 fps and the GeForce RTX 5090 near 256 fps, and the lower of the two sets the frame rate.

The same pair at every resolution

A processor pushes roughly the same number of frames whatever the resolution. A graphics card pushes far fewer as pixels go up. That is why the limit moves as you climb this table, and why a bottleneck figure quoted without a resolution means nothing.

Resolution	Estimated fps	Limited by	Gap
720p (1280 x 720)	139 fps	CPU	59.5%
1080p (1920 x 1080)	137 fps	CPU	44.6%
1440p (2560 x 1440)	136 fps	CPU	24.8%
Ultrawide 1440p (3440 x 1440)	134 fps	CPU	8.4%
4K (3840 x 2160)	103 fps	Balanced	0%
8K (7680 x 4320)	46 fps	GPU	33.5%

What to do about it

No CPU on the market fully feeds the GeForce RTX 5090 at 1080p (1920 x 1080), because at this resolution the card is simply faster than any processor can keep up with. The Ryzen 7 9850X3D closes most of the gap; the rest of it disappears on its own the moment you move to a higher resolution or preset.
