Yes but have you seen this actually measured, as being a net performance problem for AMD as compared to Intel, yet? I understand the theoretical concern.

Older (Zen 1), but you can see how even a AMD EPYC 7601 (32-core) is far slower than Intel Xeon Gold 6138 (20-core) in Postgres.
Apparently Java-benchmarks are also L3 cache heavy or something, because the Xeon Gold is faster in Java as well (at least, whatever Java benchmark Phoronix was running)
Look at PostgreSQL, where the split-L3 cache hampers the EPYC 7601's design.
As I stated earlier: in many workloads, the split-cache of EPYC seems to be a benfit. But in DATABASES, which is one major workload for any modern business, EPYC loses to a much weaker system.
