Actually the dual CPU Xeon's are still going to be a bit too much horsepower. They're worth testing on, absolutely, but our concern here is really about hitting an approximate render time target for a "middle of the road" enthusiast hardware, which is about Ryzen 2700x level. An 1800x would be a decent stand-in though, i.e. close enough. So jaf, you'd actually be our best bet at present. Get in touch if you want to give it a run. It may take some back-and-forth, i.e. multiple tests.
