And for me i'm kinda curious about the 600 series chipset. I wonder if you will be able to clock the IF higher and if the chipset will be passively cooled.
If I had to guess, the chipset will probably be passively cooled. I suspect one of the main reasons it's not with X570 is that PCIe 4.0 capable chipsets were not yet available from manufacturers like ASMedia, so AMD had to design their own. From what I've heard, the X570 chipset may actually utilize the same IO chip used in Ryzen 3000-series processors, just manufactured on a 14nm process rather than 12nm. While PCIe 4.0 may play a role in increasing power consumption, I would think that a chipset from the usual manufacturers might be a bit more efficient.
I wonder if AMD decided to just skip mid-range and lower boards entirely this generation, leaving B450 and A320 to fill those roles. The current processors have already been out for over 9 months, with the next generation likely coming within the next 6 month or so. Perhaps they'll just hold off on a motherboard lineup refresh until near the release of the 4000-series, so that they can guarantee compatibility with the new processors at launch.
