There are no Epyc workstations chips with clock speeds comparable to Threadripper/Xeon-W. At least for the currently released products. And thus I consider Threadripper the closest competition to Xeon-W, not Epyc. AMD also lists ECC memory support as a feature for Threadripper.

That said, the new Xeon-W series has more memory channels (6) and supports more RAM (up to 2 TB) than any existing Threadripper product. I.e., AMD doesn't have an equivalent product for all use cases yet.

However, we don't know the Zen 2 Threadripper lineup and the frequencies for the different Zen 2 Epyc SKUs are also not public yet. AMD could release Threadripper with support for RDIMM/LRDIMM or Epyc chips with higher clock speeds to better compete against Xeon-W.
