I really wished they kept ddr4 support and could bring this to AM4, it could have been the true swan song for the platform instead of the 5800X3D that is looking to be mostly disappointing. I know i know, AM4 had a good run, but a person can always dream.
It will be interesting to see what AM5 launches with, there's little information on how the line up will look like but there's a lot of talk about Zen 4 having some compute units either in the IO die or some chiplet and APUs are destined to move to a modular design instead of the current monolithic dies, with how long it will take for something like this to come to the desktop AM5 is anyones guess, there may be no reason to, after all it's zen3+ and not zen4, why adapt it to fit into the AM5 platform when they can move forward with whatever plans they have for future APUs? (only reason I can see is prebuilts that certainly want new material to market asap)
