Xeon is still better for complex workloads like databases since its inter-core latency is lower. Epyc is better when there is no shared data between cores. I'd say public cloud will pick up Epyc for such workloads. They may also use Epyc as a 4x8 core VMs with VM affinity locked to each die. Xeon will continue to be the standard for complex workloads.

Has that been demonstrated to be true, though, especially in light of Epyc's much wider PCIe bandwidth? For example, would a high-concurrency OLTP-type workload suffer as much from increased inter-core latency as a single-query OLAP workload?
