Do the Core i7-12700K and Radeon RX 6950 XT bottleneck each other?

No. At 1080p (1920 x 1080) the Core i7-12700K keeps the Radeon RX 6950 XT fed with a little headroom to spare, which is what a balanced build looks like. Expect about 105 fps on High.

How many fps do the Core i7-12700K and Radeon RX 6950 XT get at 1080p (1920 x 1080)?

Around 105 fps on the High preset. The Core i7-12700K tops out near 149 fps and the Radeon RX 6950 XT near 110 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)	141 fps	CPU	0.9%
1080p (1920 x 1080)	105 fps	Balanced	0%
1440p (2560 x 1440)	79 fps	Balanced	0%
Ultrawide 1440p (3440 x 1440)	65 fps	GPU	10.7%
4K (3840 x 2160)	46 fps	GPU	37.9%
8K (7680 x 4320)	16 fps	GPU	78.3%

What to do about it

Nothing to fix. At 1080p (1920 x 1080) the Core i7-12700K has just enough headroom over the Radeon RX 6950 XT to keep the card fed without wasting money on either side. This is what a balanced build looks like.
