Whatever the reviews are this is what I am going to do, compare apples-to-apples. That means comparing eight core parts against each other, 5800X vs i7-11700K and 5800X vs i9-11900K. If I need a 10, 12, 14, 16 or 18 core product then we move to Intel's last generation parts, either their HEDT or i9-10900K parts.
AMD might also release another eight core part something like 5800XT or 5850X with a boost single core clock of say 5.0GHz. If I were AMD I would have been binning the higher end 5800X parts from the get go, call it Operation Counterstrike, building up an inventory of those parts, so that even if slightly slower in single core performance, would be in stock vs what is likely to be out of stock eight core Rocket Lake parts.
