The main problem with those is the memory controller starts to degrade a lot when you use all 128 of those cores.
We were doing some testing and > 96 cores at 100% caused a massive degradation in performance. We ended up going with dual 32C/64T Epycs (which cost twice as much) as a result. If they fix it in the Altra One chips they will be back on the table though because they were very good power wise for our workload and quite price competitive in a supermicro chassis.
