This is AMD's mulligan because Intel's Raptor Lake kicked the shit out of their original launch. Glorified rebrand so they could cut pricing without looking weak.
In line with what I said earlier about Intel, with this generation, the new value strat for tech-savvy CPU buyers is to buy the non-K or non-X variants, and then run them in a higher power state (i.e. PL1 for Intel; PBO for AMD). With AMD there isn't even a binning advantage for the X-variants this generation. The non-X variants are holding equal or superior overclocks. Their on-paper turbo is a mere 1.8% less, and both the stock and PBO benchmark roundup averages are ~1.0% inferior. For savings of $70 (R5/R7), or $120 (R9), it's a no brainer.
As he mentions everything else is the same unlike with Intel's non-K variants. Don't waste time with manual overclocks, either, even though you can on the non-X variants, that's a thing of the past, the automatically handled dynamic overclocking is superior for nearly all real-world tasks, specifically gaming, the point is to just feed the CPU more power and let it automatically sort out its dynamic overclocking with what it is given. PBO is the way to go.
Only thing now is to wait to see how much of a benefit the 3D cache offers this time around, and how much AMD is going to charge for it.
