zen 2 was 8 cores per chiplet, 4 cores per ccx. It looks like zen 3 is 8 cores per CCX. I don't know enough about cpu architecture to speculate on core config though.They mentioned earlier on in the presentation that gaming performance benefits from the low latency of having all 8 cores on a single chiplet. So I'd assume they'd make the 5800X have all 8 cores on one in that case.
