There is an extremely good chance I am wrong about that. I always buy a new motherboard when I buy a new processor so I really don't keep track of that stuff. It just seems like I would remember the huge outcry if that were the case, so I assumed it would work.

indeed forward compatibility of old processors should be possible considering that they just refreshed 1600AF and 1200AF, otherwise whats the point when they aren't even compatible with X570 and B550 motherboards?

trolling an adult is very dangerous, don't try it at home nor at work. you don't want to play tag with a rabid man.

IMO its great news, if true.

The backward compability taken to extremes has been a huge burden to the motherboard manufacturers, to a point where it started inflating the cost of the new products and reduce the motivation to
invest in products for this platform altogether. Not to mention it definitely affected the support of the "prime time" (i.e. current gen) product support as well, since some of the resources had to be spent on products of the past generations).

I've been waiting for this final DDR4 gen and the B550 boards to finally build a new PC, and while it doesn't bother me that there might be no backwards compatibility, I can understand there are many who are unhappy about it.

Does this mean there won't be a new chipset with the 4000 series, no x670?

This. I ran a 1700X, 3700X, and now a 3900X in my X370 ROG CrossHair VI. Ive gotten my money worth out of the board and Im sure Asus is tired of supporting a product that was revenue for them many financial quarters ago. Move toward the future and stop hacking together bios fixes and updates to support my old chipset.

I don't think I could disagree with you more. I don't see why they wouldn't inflate the costs more now that you have to update your mobo to get the new chips. The Intel boards seemed to have crept up in price too.

Aside from the Bios ROM size limitations, which seemed like manufacturers being cheap more than anything, I don't really see how having to support more CPUs limited X470 in any way (or how X570 was really any better than X470 assuming that X570 did in fact not support Zen 1; I saw reviews of the 3950X on a cheap B350 board and it didn't perform much worse [if at all]). I could understand if they changed the pin-out, but it really seems odd that a high-end X470 board is that much worse than a B550 board that it can't support Zen 3 (or that the CPU would care that much about PCIe 3 vs 4 as that seems to be the main difference).

Now obviously you know WAY more than I do, but from my perspective, this was the one nice thing AMD had over Intel (okay, maybe not the only thing, but I liked knowing thinking that I'd get more CPU support). It gets cumbersome having to switch everything out/possibly reinstall windows+other programs every time I upgrade CPUs (which isn't even that often compared to some of yall!). At least, I usually update every other Gen (I didn't get Ivy or DC for my P67 or Z87 boards). Got my 2700X for ~<$100 open box with BL3 or I'd still be using my 1800x.

Again, I don't mind upgrading the board that much, but it bothers me that the chip is likely going to fit in my board, but won't work. Hopefully AMD can give us a reason (not that they owe that to us). I'll be sticking with AMD regardless, I'm just a bit disappointed about this (was hoping to skip Ryzen 3K).

I am! I upgraded specifically assuming I would be able to run the next gen chips.... lame

Since they didn't keep their promise, I won't keep mine of supporting AMD.

They are doing what they said they would do 3 years ago

Also tend to agree with The Stilt on the subject - it's time.

Three gens of chip , managing to double the core count and generally being able to use the same motherboard for all without major sacrifices is pretty remarkable.
