I wouldn't compare the 7980XE and 2990WX but rather the 2950X. The power consumption scales with the core count so only 18 vs 16 cores makes sense, both 18 vs 32 and 18 vs 8 are equally pointless.

The real question is does the IF figure include L2/L3 intra CCX traffic?
Because if that still has to be added on top of it all the IF is seriously power hungry will the cores themselves are impressively efficient.
