Do the Core i7-12700K and GeForce RTX 4080 bottleneck each other?

Yes. At 1080p (1920 x 1080) the Core i7-12700K is the limit and holds the GeForce RTX 4080 back by about 1.7%, for roughly 141 fps on High. No practical impact.

How many fps do the Core i7-12700K and GeForce RTX 4080 get at 1080p (1920 x 1080)?

Around 141 fps on the High preset. The Core i7-12700K tops out near 149 fps and the GeForce RTX 4080 near 152 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)	143 fps	CPU	28.2%
1080p (1920 x 1080)	141 fps	CPU	1.7%
1440p (2560 x 1440)	107 fps	Balanced	0%
Ultrawide 1440p (3440 x 1440)	89 fps	Balanced	0%
4K (3840 x 2160)	62 fps	GPU	14.3%
8K (7680 x 4320)	22 fps	GPU	70%

What to do about it

No CPU on the market fully feeds the GeForce RTX 4080 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.
