I don't think it will be supported on most the Z790 boards themselves, but the lower chipsets from what I have read. Though this article conflicts that.Interesting, also what advantage does Z790 have over Z690 would be my question? Zen 4 IPC and clock speed increase still appears to not match even Alder Lake P core performance while Raptor Lake should take it a notch above Alder Lake. Anyways Intel supporting both DDR 4 and 5 with their newest generations does put the squeeze on AMD I do believe. I hope Intel does support DDR4/5 with Z790.
If that option is available for the motherboard makers, I see them having cheaper Z790 boards with DDR4 if they can make money from them. Plus later when DDR 5 only CPUs from Intel, some of those same buyers will migrate yet again to a new motherboard. Win Win. Plus if Raptor Lake with DDR 4 is just as fast or faster than Zen 4 with DDR5 in most tasks then that would be icing on the cake. I see Intel as already turning it around in the CPU department against AMD.I don't think it will be supported on most the Z790 boards themselves, but the lower chipsets from what I have read.

The memory controller is on the CPU; obviously there is some implementation logic associated with the chipset, but if Z790 supports Alder Lake, then DDR4 Z790 boards should also be possible.I hope Intel does support DDR4/5 with Z790.
Yep limits the cost of the upgrade. And that is nice.It's an added incentive for people running DDR4 boards to finally upgrade to something new while still retaining older parts that are still usefull.
