The short answer

In a typical one of 8 popular games at 1080p High with an RTX 5090, the Ryzen 7 7800X3D gets about 191 FPS and the Core i9-14900K about 176 FPS. With a slower graphics card, or at 1440p and 4K, the card sets the FPS more often and the gap gets smaller.

The Ryzen 7 7800X3D uses the AM5 socket and the Core i9-14900K uses LGA1700, so they need different motherboards. The Ryzen 7 7800X3D takes DDR5 memory and the Core i9-14900K takes DDR4/DDR5. Cores and threads: 8 / 16 on the Ryzen 7 7800X3D, 24 / 32 on the Core i9-14900K. Neither comes with a cooler, so budget for one.
