I currently have an Intel Core i7-12700K paired with an AMD Radeon RX 9070 XT, and I game at 1440p on an ultrawide monitor. I keep hearing that AMD processors can be significantly better for gaming, but my current motherboard only supports Intel CPUs. Would replacing the motherboard and moving to an AMD processor produce a noticeable FPS increase? I'm using DDR5 memory.

With DDR5, moving to an AM5 system would be relatively straightforward, but you’d still need a new motherboard and CPU, so the cost may not be justified. Benchmarks can show anything from a minor improvement to a very large one in unusually CPU-bound situations, but the typical result at your resolution should be modest. If you do find a good deal on a used X3D processor and motherboard, you could consider selling the existing parts, but otherwise enjoying the current setup is probably the better choice.
The 12700K is still a strong gaming processor and should be perfectly adequate for this GPU. A newer AMD X3D chip can make a substantial difference in CPU-limited games, especially esports titles, simulation-heavy games, or games like Rust and Tarkov. However, those gains are much less common at 1440p ultrawide, so I’d wait until you have a specific game where the CPU is clearly holding you back.
It depends heavily on the games and settings, but at 1440p ultrawide your RX 9070 XT will usually be the limiting factor before the 12700K. In most games at high or ultra settings, switching platforms would provide little or no noticeable improvement. I’d keep the current system rather than spend money on a motherboard and CPU upgrade.
A cheaper alternative would be looking for a reasonably priced used X3D CPU and motherboard bundle, then selling the 12700K platform. DDR5 makes that swap easier, but I’d still compare the total cost against the actual FPS gains in the games you play.
