"Zen 3 is looking like an incremental improvement over Zen 2 rather than a radical manufacturing shift."

That is close to what I recall Norrod saying in one of the early interviews about zen3.  Later, though, a couple from AMD, including Norrod, started talking about big gains in zen3.   So, when do we get the true story?  Is all the improvement depending on that core grouping redesign?

According to OEM slides obtained by German website HardwareLUXX, AMD's upcoming Zen 3-based EPYC Milan server CPUs will offer up to a 20% increase over the current Zen 2-based EPYC Rome CPUs. Milan CPUs may also reorganize the L3 cache on the chip, allowing for all 32 MB of L3 cache to be shared between all cores rather than splitting the L3 cache into two 16 MB segments.
