No, AMD's latency is generally worse than Intel's on Zen chips. Here's the first example I could Google [1], but the same trends repeat themselves across many benchmarks.

My overall impression is that the typical gap is 5-10 ns.

Thanks for the link. I will take a look.

As I clarified below, in my other comment, we were unable to get new Zen systems. So I’m not knowledgeable about their behavior.

However, I need to make my own benchmarks to see how this increased latency affects performance of different work loads and scenarios.
