I'm trying to understand how performance varies between using CL32 32GB DDR5 RAM and CL30 32GB DDR5 RAM with the 9800X3D CPU. Are there significant differences in gaming or performance metrics, or are they about the same?

Most of the benchmarks show little to no difference. The X3D CPU has a massive L3 cache, which makes RAM timings less critical. Some games do show a few FPS differences, especially in 1% lows, but overall it’s negligible for casual gamers.
Yeah, in real-world usage, the CL rating alone doesn't say much if speeds are the same. Even benchmarks with lower CL RAM showed little difference. If you're focused on gaming, probably best to aim for something around 6000 CL30 if you can.
In practical terms, there's really not much difference between CL30 and CL32 with the X3D CPU. Even lower-speed RAM like CL40 performs reasonably well. It's all about getting decent speeds over the timings when you're using these CPUs.
From what I gather, the difference between CL30 and CL32 is pretty minimal, especially with the 9800X3D. Some tests, like those from Gamers Nexus, found that when they're at the same speed, the performance varies within the margin of error.
Honestly, I've run into a similar situation with my setup. I had to downclock from 6000 MHz CL30 to 5200 MHz CL36 for stability, and even then, I barely noticed a drop in performance—like 0-1% in gaming.
