Goodness. Soo get this: good 13900K CPUs get up binned to 13900KS CPUs, the best of which have recently turned into 14900K CPUs, making the latest flagship an up-bin of an up-bin. And all you're paying for with each up-bin is 100-200MHz at similar voltages, no guarantee of IMC which is still all over the place and for all you know, an i5 may run DDR5 better than your up-binned up-bin. And now you're telling me there's even more up-binning to the 14900KS?? Making this, what? An up-bin, of an up-bin, of an up-bin, of an up-bin?? Amazing!!
Bought a used, open box without original box ROG Z690 Maximus and ordered a 12100 just for a boot test. Plan is (was?) to return it after checking that all’s well with the motherboard and keep an eye for sales in i7s and i9s this season, just happened to glance at the Silicon Prediction (SP) score and it says 148! Wtf? I believe the average for the 13900k is like 99 with the best being around 115. Does this mean anything in the context of an i3 or is it sort of meaningless?
What will matter more than the Z690 or Z790 chipset is the overall feature-set and design of the board, as the only difference between the two chipsets is one is capable of more connectivity. But just because it is, doesn't mean all Z790 boards will offer the connectivity the chipset is capable of and will in all likelihood use the name purely for marketing. So when looking up boards, look at the overall feature-set of the board and judge the price-value accordingly. For RAM OC, I again do not think the chipset matters, as a 2-DIMM Z690 APEX will likely edge out all 4-DIMM Z790 boards, so again it comes down to the specific board, what it offers and how much it costs. Beyond that the chipset name is just marketing.
