## Summary

AMD architect Mike Clark says Zen 6c keeps the same software-facing design as Zen 6 but uses larger queues because it has a lower frequency target. Clark says Zen 6 reduces integer multiply units from three to two, adds two VNNI units, and enables full 4MB-per-core L3 cache in the dense Zen 6 core, with 32 cores and 128MB of L3.
