Zen 4 Infinity Fabric clock reaches 3 GHz

I was wondering if AMD would make Infinity Fabric wider or faster to support DDR5 bandwidth and the latest rumors indicate that they're continuing to clock up with an FCLK of 3.0 GHz supporting DDR5-6000 at 1:1 ratio.

I'm still not sure how AMD's LPDDR5 implementation works; maybe the CCX can only realize half of main memory bandwidth? Apple has a similar bottleneck.
