According to articles on Forbes and Extremetech, Intel currently has 99% of the server market. This is a new product that may affect Intel, but it hasn't done anything yet. So far this is just speculation then.
It hasn't done anything yet because it hasn't been released yet. So of course it is speculation. However, based on the downclocked Ryzen benchmarks I have seen, it should significantly outperform anything Intel has in Perf/W at the 5W/core level. And Perf/W is what datacenters care about.
I'm just trying to relate OP's comment to changes in the conference or even claims about a market effect. It seems like wishful thinking.
AMD will have to also do chipsets right for the platform to have a chance - they didn't really prove that yet.
